cientists at Northwestern University announced new technology for Canon BP-911 Charger batteries that could last 10 times as long and charge 10 times as fast as they do today. What would it be like to charge your laptop from empty to full in 15 minutes?
For years now, ORANGE SPV M600 PDA battery have been the weak link in most consumer electronics. Take smart phones, for example. You can stream video in HD over a fast 4G data connection, but you won’t be able to do it for long without plugging in. The blazing multi-core chips that allow laptops to multitask effectively also drain their Canon Bp-711 Battery in just a few hours under heavy use. But scientists at Northwestern University in Chicago announced a breakthrough last week that could result in lithium-ion batteries (the kind found in most rechargeable gadgets) with a 10-fold increase in both SONY HDR-SR60 Battery life and charging speed.

Just to put that in perspective, imagine being able to use your smart phone for a solid week without getting a low-battery warning – and then being able to charge it up again in just minutes. The technology is still a long way from mass production, but BBC News quotes one scientist from the team as saying that these new ACER Aspire 5670 Series Laptop AC Adapter batteries could hit the market in three to five years.

How does it work? Well, lithium-ion OLYMPUS EVOLT E-410 Digital Camera batteries consist of layers upon layers of graphene, sheets of carbon atoms just one atom thick. Lithium ions occupy the space between these layers, and creep from layer to layer as the battery charges or empties. A HP Pavilion dv9700 Laptop AC Adapter battery can only hold so many ions in a certain amount of physical space, and speed at which the ions can move from layer to layer limits charging speeds.

The Northwestern scientists, led by Professor Harold Kung, made two discoveries. First, they filled the area between the graphene sheets with tiny, flexible clusters of silicon, which allows about 10 times as many lithium ions to be held. Both the graphene (carbon) and the silicon flex with the Panasonic Lumix Dmc-fz30 Battery ’s charge cycles, but don’t break.

Second, Professor Kung’s team decided to perforate the graphene sheets. If charge time is limited by how quickly ions can move from layer to layer, why not give them a shortcut? The researchers drilled millions of tiny holes (around 20 nanometers wide) in the sheets, allowing the ions to flow more freely. That means power can be pumped much more quickly into the Compaq Presario nx9010 Battery, allowing it to be fully charged in just minutes.

The downside to the new technique is that the comPAQ Presario CQ61-100 Laptop AC Adapter battery is more susceptible to degradation: after about 150 charge cycles, or about a year of operation, the capacity and charging speed start to diminish sharply. But even at that point, the battery would still be five times more effective than what we have today, and 150 charge cycles equals 1,500 charge cycles of a current SONY DCR-SR32E Battery.

Readers, are you excited about the prospect of a tenfold-improved SONY DCR-SR32E Battery? Or are you jaded by previous battery breakthroughs that never made it to market? Let us know in the comments.

WASHINGTON (AP) — New fires involving the lithium-ion Dell Inspiron 8600 Laptop AC Adapter batteries in General Motors Co.’s Chevrolet Volt have prompted an investigation to assess the risk of fire in the electric car after a serious crash, the National Highway Traffic Safety Administration said Friday.

One Volt OLYMPUS Tough 700 Series Charger battery pack that was being closely monitored following a government crash test caught fire Thursday, the safety administration said in a statement. Another recently crash-tested Motorola GP1200 battery emitted smoke and sparks, the statement said.

GM, which was informed of the investigation on Friday, said in a statement that the Volt “is safe and does not present undue risk as part of normal operation or immediately after a severe crash.”

The latest fires are in addition to a KENWOOD PB34 battery fire in a crash-tested Volt six months ago.

NHTSA learned of a possible fire risk involving damaged Volt Compaq 610 Battery when a fire erupted in a Volt that was being stored in a parking lot of a test facility in Burlington, Wis. The fire was severe enough to cause several other vehicles parked nearby to catch fire as well.

The car had been subjected to a side-impact crash test more than three weeks earlier, on May 12, during which the ACER Aspire 5580 Laptop AC Adapter battery was punctured and its coolant line ruptured.

Last week’s tests of three battery packs were designed to replicate the May test. In that test, the Volt was subjected to a simulated side-impact collision into a narrow object like a tree or pole followed by a rollover, the agency said.

The first battery tested last week didn’t catch fire. But a SONY CCD-TR105 Battery test on Nov. 17 initially experienced a temporary temperature increase, and on Thursday caught fire while being monitored. Another SAMSUNG PL70 Charger battery tested on Nov. 18, which was rotated 180 degrees within hours after the test, began to smoke and emit sparks shortly after the rotation.

The tests were conducted by NHTSA and the Energy and Defense departments at a defense facility near Hampton Roads, Va.

So far, no fires have been reported in Volts involved in roadway crashes, NHTSA said. More than 5,000 of the vehicles have been sold.

It’s too soon to tell whether the investigation will lead to a recall of any vehicles or parts, but the government will ensure consumers are informed promptly if that occurs, the agency said.

With its OnStar safety communications systems a part of the car, “GM knows real time about any crash significant enough to potentially compromise Sony Cybershot DSC-T100 Charger battery integrity,” the automaker said. “Since July, GM has implemented a post-crash protocol that includes the depowering of the battery after a severe crash, returning the Olympus Li-70b Battery to a safe and low-powered state.”

Electric vehicles are critical to President Barack Obama’s plans to reduce U.S. dependence on foreign oil. He has called for putting 1 million of the vehicles on the road by 2015.

The Volt and Nissan’s Leaf, with more than 8,000 cars on the road in the U.S., are among the first mass-marketed plug-in electric cars. They went on sale in the 2011 model year. Other automakers are also working on electric vehicles.

Safety testing hasn’t raised concerns about electric vehicles other than the Volt, NHTSA said. But the agency is asking manufacturers who have electric cars on the market, or who plan to introduce electric vehicles in the near future, for more detailed information on their Toshiba pa3285u-1brs Battery testing as well as what procedures they have established for discharging and handling batteries, including recommendations for reducing fire risks.

“NHTSA continues to believe that electric vehicles have incredible potential to save consumers money at the pump, help protect the environment, create jobs and strengthen national security by reducing our dependence on oil,” the agency said.

After the first CANON NB-2LH battery fire, GM officials complained that NHTSA did not drain the battery of energy as called for under the automaker’s crash procedures. NHTSA normally drains fuel from gasoline-powered cars after crash tests, they said.

Lithium-ion Dell 312-0711 Battery, which are rechargeable, have been the subject of several recalls of consumer electronics. Millions of laptop Acer Aspire 7551-3634 Battery made by Sony Corp. for Apple Inc., Dell Inc., Lenovo Group Ltd. and other PC makers were recalled in 2006 and 2007 after it was discovered that they could overheat and ignite.

The Federal Aviation Administration issued a warning to airlines about the potential for fires in cargo containing lithium-ion and non-rechargeable lithium metal ACER Aspire 5310 Laptop AC Adapter batteries after a United Parcel Service plane crashed near Dubai last year, killing both pilots. The plane, which was on fire, was carrying thousands of lithium batteries.

Incorrectly packaged, damaged or overheated Konica Minolta Np-700 Battery can catch fire, the FAA said. Fires involving lithium-ion batteries can reach 1,100 degrees, close to the melting point of aluminum, a key material in airplane construction. Lithium-metal SONY CCD-SC55 Battery fires are far hotter, capable of reaching 4,000 degrees.

GM and NHTSA have pointed out that cars with gasoline-powered engines are susceptible to fires after a crash.

In the event of a crash, NHTSA’s advice to consumers is to do the same thing they would do in a gasoline-powered car — get out of the vehicle and move a safe distance away. The agency also recommends against storing a severely damaged electric car in a garage or near other vehicles.

There are many features that your NP-130 CASIO camera performs which consume more battery power. The absolute worst is using a camera light that is powered from your camera’s battery. We recommend using the camera light that is powered from its own power supply or CASIO NP-130 battery. Another is by never rewinding or fast-forwarding your tapes on your camera. Before you leave your house, cue up your tapes to the desired location with your camera plugged to the ac power supply Fit Models:Casio EXILIM EX-H30,Casio EXILIM EX-ZR100.

Use rechargeable batteries
Use rechargeable batteries for notebook computer desktop relative to one of the advantages, it can greatly facilitate the environment in a variety of laptop use. Introduced the first battery is nickel-cadmium battery (NiCd), but this battery has a “memory effect”, each must be discharged before charging, very easy to use, soon to be nickel-metal hydride battery (NiMH) replaced, NiMH is not only not “memory effect”, and can make more per unit weight of 10% of the electricity. The most commonly used battery is a lithium-ion battery (Li-Ion), it is also no “memory effect”, compared with NiMH, get more weight per unit of electricity, the price twice as high than the NiMH. In the same weight, battery life of these three ratio is 1:1.2:1.9.
Laptop batteries currently used in three main categories: 1. Nickel-cadmium batteries, 2 NiMH batteries, 3 lithium acer aspire 3000 battery; they are generally expressed as: nickel-cadmium NI-CD, Ni-MH NI-MH, lithium LI.
Purchase or replace the battery pack when, for many users, the “batteries” may be unfamiliar. The outset, batteries and battery are two concepts. A battery is composed of several slightly larger than the thumb, cylindrical, about 7-8 cm high, the voltage of 3.6v small units. They are the batteries, like a small battery, after a series combination, we see the battery. Then talk about how to determine if the battery is a few core:
One way: Disconnect the battery for dell latitude d630 to see him the number of contacts, a few is a few of the core. But this is the “minister” approach. We take a look at “Cao Chong,” is how, “said the elephant”: take a look at your battery’s nominal number of v, such as 14.4v, then divide by 3.6 to get 4, then the proof is the four cells in series together. Then look at the capacity of the battery block, such as 3800mAh, then prove the above mentioned two series acer aspire 1410 series battery, because the small battery capacity of 1500-2000mAh, even more, to two groups in order to achieve 3800mAh. According to these two judgments, then the battery is 4 × 2 = 8 cores.
The composition of dell laptop battery
Laptop battery from the shell, circuit board and batteries, belonging to lithium-ion battery. Ordinary people talking about batteries means the number of batteries within the battery, mAh refers to the notebook battery capacity.
Mainly by the protection circuit board (or secondary protection circuit), and the capacity indicator circuit of two parts, the laptop battery charge and discharge, and security management.
Battery standby time determined mainly by the mAh value. Under normal circumstances, a few more batteries, mAh greater the longer standby time. The life of hp laptop battery charge and discharge times measured by the quality of qualified products generally 500-600 times. Therefore, the effective use of laptop battery life of 2 years or less, will be expire aging battery, standby time dropped dramatically affect the mobility of notebook computers.
Laptop battery tips
In fact, how to make good use of laptop battery battery, how to extend their use of time and the life of the other issues, no doubt troubled by the majority of laptop users in the heart of a problem, the use of dell inspiron 1545 laptop battery there are a variety of methods and techniques, which requires us to usually use more learning and application.
(A) to sleep fast
Temporarily using a laptop computer, to save battery ac adapter for compaq presario 945ap power, we can set the power management options, allowing the system to sleep after a period of time, but shorter or longer will have to wait a few minutes, there is no way to make the notebook computer system immediately enter the sleep state?
The notebook computer system to sleep, a quick and easy way is to directly turn off the display. Press display just little things, you can immediately make the laptop sleep, effectively conserve battery power. When you need to re-use, simply open the display, the system will automatically return to the state before the operation.
(B) screen-saving mode
TFT screen is the largest notebook computer power components, in order to reduce the use of the hp pavilion zv5000 battery when the power it consumes, notebook computer manufacturers of all kinds of devices, but in general are based on the lower screen brightness, and even off-screen method.
In some laptops the power management settings you can customize the brightness of the screen, most laptops can be specific shortcut keys adjust the screen brightness, generally 6 to 8 level brightness adjustment.
(C) energy-saving settings
Desktop using the AC, the computer most people may not attach great importance to energy-saving features, but need to use battery-powered notebook computers, the use of energy-saving features should be taken seriously. How to design more energy-efficient computer hardware, this is not the user to solve the problem. The user can do is set the computer on the effective use of energy-saving options.
Energy-saving setting, there are two require the user to adjust: First, the computer’s BIOS setup program on the energy saving mode setting; the most important is in the operating system has many energy-saving settings and operation. In the practical implementation of computer systems, Windows systems should give priority to energy-saving settings in the CMOS settings.
1.BIOS energy-saving settings
In the CMOS settings and large have a “PowerSavings”, where you can select “MaximumBatteryLife” and “MaximumPerformance” and many other options. “MaximumBatteryLife” energy-saving mode is the default setting. Laptop power saving mode in several states, such IdleMode idle mode, StandbyMode standby (wait) mode, SuspendMode suspension (sleep) mode. These settings on the laptop, able to regulate power consumption, mainly in the computer power state, the timely closure of some facilities without the use of the system. If the wait state, turn off the monitor and hard drive; to sleep, in addition to turning off the display and hard drive, but also the contents of memory can be saved to the hard disk, the basic maintenance of the entire computer system off, once activated, or restart the computer, the desktop return to the exact state before sleep. Energy-saving settings in the CMOS is mainly set by the IdleMode into StandbyMode of StandbyTimeout time, set by the StandbyMode into SuspendMode of SuspendTimeout time. Laptop PhoenixBIOS the majority. Different BIOS settings may be somewhat different energy, should carefully read the screen prompts.
2.Windows energy-saving settings
For general users, in the Windows system may operate better understanding of energy management simpler. Windows help file, in the “management of hardware and software” entries, there are two energy-saving notebook computers with the content: “Managing energy consumption” and “use of portable machine” in the “management of portable computer power.” Energy-saving settings during Windows, should read these.
In the Windows “Control Panel”, click “Power Management”, you can open the “Power Management Properties” dialog box. In the “Power Management Properties” dialog box, should be “power scheme” set to “Portable / Laptop” and reasonable arrangements “system waiting for”, “Close the Monitor,” “Turn off hard disks” option . The computer can manipulate the different options will have some differences, the new factory and the latest computer software will be more operational options, a detailed set of functions should be based on the computer itself and the Windows help file to.
In addition, if your laptop built-in infrared port, when not to ban it, you can extend laptop battery life.
(D) alarm settings
Set the battery alarm in time to give prompt the user to save the information. Method is to click open the “Control Panel”, double-click “Power” option, click on “alert” menu bar, “Low battery alarm” column Windows98 default is 10%, “a serious shortage of dell inspiron 1525 battery alarm” column Windows98 default is 3%, can be appropriate changes as needed. Click on both the [Alarm Response] button, the “Sound Alarm” and “message” is selected, the “power level” is optional. This is used when the battery alarm limit, a warning window will pop up, and the buzzer alarm will sound to prompt the user to save information in a timely manner. Finally click [OK] button to exit the power management settings.
(E) on energy-saving function
In the “extended laptop compaq presario v3070tu battery life technology” section, we have introduced energy-saving feature is a CPU usage of the technology, which allows the performance of laptop computers will play its battery to achieve the best balance between.
Most new models of notebook computers in the BIOS, the CPU energy-saving technologies are given support is enabled by default, if not open as long as the BIOS will support the option to open it OK.
(F) the use of third-party software to monitor battery for compaq contura 430cx status
In addition to Windows built-in power management features, there are a lot of utility to monitor battery status. For example, PowerCenter is a power monitoring tool, available for free download . Only 800KB, is a service designed for notebook software. PowerCenter not only shows the percentage of battery capacity, but also to show the actual hours and minutes the time available.
There are three kinds of PowerCenter display.
(1) FullDisplay: In the open window displays detailed information, including the use of battery or AC power, the percentage of battery remaining and available time.
(2) CompactDisplay: in use is always displayed at the top of the window.
(3) MinimizeDisplay: PowerCenter reduced to make the Windows taskbar, and the information is relatively simple.
PowerCenter is also attached to a control center, can make up to six kinds of warning. When the dell mini 1012 n450 laptop battery- down to a certain extent, timely warning to the user, save the file being processed. In order not to waste electricity and CPU resources, PowerCenter automatically detect the battery status changes.
(G) intentionally run out of battery
Regularly run out of battery, in order to ensure a full charge. If you need to completely run out of battery power, which would be: in PowerManagement dialog box, select BatteryDrain this particular power mode, all of its three RunningonBatteries options are set to Never, this laptop is the computer will continue to run. Select the mode, then enter the Alarms tab, remove the LowBattery and CriticalBattery Warning check box check mark (so that when sony vaio pcg-k37 battery power is low, the machine will not enter the suspended state). Next, let the computer run the CPU-time tasks, such as the computer automatically run some of the computational complexity of the 3D demo program, which will soon run out of battery power remaining, of course, these disposal Do not forget to unplug the AC the plug.

For the consumer handheld devices, the historic two AA (alkaline or Ni-MH battery) power is the most commonly used Panasonic Nv-gs11 Battery solutions, especially in the GPS navigation devices, digital cameras and MP3 players. AA batteries easy to buy, low cost and high power density. In these portable devices, many have adopted the plug-in AC adapter, and provides a USB bus (for data transfer) as a supplement battery power. USB bus power can also be used. The question is how these three different power supply (two AA batteries, AC adapter and USB) to seamlessly switch between. LTC3456 is a suitable solution.

 LTC3456 is a complete system power supply IC, AC adapter can be achieved, USB and two AA Dell Lite-On PA-1131-02D Adapter batteries power flux between the seamless management and comply with USB power standards, all of these functions are integrated in a 4mm x 4mm QFN within the package (Figure 1). The device generates two separate power rails: a 3.3V (fixed) main power supply and a 1.8V (adjustable) core power supply. In addition, LTC3456 also includes a fully functional USB power manager, used to store a hot plug power supply (Hot Swap) output and is suitable for low-battery comparator or LDO controller gain independent parts. The device also generates an always-running VMAX output, the output is suitable for such real-time clock for the shutdown period also necessary even in the working state of the key components in power transmission.

        LTC3456 contains four high efficiency up to 92% of the 1MHz fixed-frequency switching regulators. Figure 2 shows a typical LTC3456 application. Used in portable applications, most processors require dual-supply voltage. The voltage can be 3.3V (for I / O circuits) and 1.5V or 1.8V (for the processor core). In addition, the processor may also require the power to start in a specific order to prevent blocking or error processor start. Typically, the core power to the I / O power supply before the rise.
 

Figure 2 is based LTC3456 complete power solutions, including a 1.8V output (for the processor core), a 3.3V output (for I / O), a hot-plug power supply 3.3V (used to store plug-in) and a VMAX output (for RTC)
        LTC3456 has a main output for the kernel and built-in power sequencing function. On power, VINT output (a fixed 3.3V power supply) on the implementation of the first power-on operation. It is responsible for most of the internal circuitry. Response to the external load on the output size is limited. Adjustable from 0.8V to 1.8V core output then increased, followed by VMAIN output. VMAIN output (a fixed 3.3V power supply) into the regulation state in the kernel output after delay 0.8ms (typical) power. VMAIN output by the VINT output through an internal 0.4Ω (typ) PMOS switch and produce, and can be used to I / O circuitry. 0.8ms delay processor power in the external circuit to complete the system clock on the stability and load internal registers provide a sufficient time.

        LTC3456 generates an adjustable 0.8V to 1.8V core output, the output for the new low-voltage processors (ARM, etc.) power supply. LTC3456 output control circuit allows the kernel to work 100% duty cycle. When the kernel output from the ACER TravelMate 527 Laptop AC Adapter batteries to power, it provides low dropout operation, extending battery life. When the battery-powered, the main converter and core converters offer a burst mode operation (MODE pin can be used to select), so in light load conditions to achieve high efficiency. In the case of battery-powered, the kernel has more than 92% converter efficiency. When the USB / wall power supply to power, the Burst Mode operation is disabled. When powered from the USB to the main converter up to 90% efficiency.

        LTC3456 suitable for flash memory card with a built-in hot swap power supply output. The hot-plug output with short circuit and reverse voltage isolation. It allows plug-in system stored on the hot plug. It has a suitable power supply to the flash memory card, 120mA (typical) Built-in current limit.

        LTC3456 provides the core for the main output and output short circuit protection. It also provides all of the output (VMAX output excluded) provides output disconnect. In shutdown mode, the core output, main output, and outputs are discharged to ground hot. In VBATT, VINT, VEXT and USB voltage, VMAX output is the highest. The output can be used to provide the maximum output current of 1mA. Even if the IC is in shutdown mode in the case, VMAX output will remain running, and thus suitable for real-time clock to the critical system components such as power supply.

        Table 1 LTC3456 PowerPath summary of the work patterns and characteristics

PowerPath control

        LTC3456 includes a proprietary PowerPath control circuitry to achieve seamless handover between system power (from two AA NOKIA 9210 PDA battery to USB / wall power, or vice versa). Figure 3 shows a simplified block diagram of an internal power supply path. AC adapter and the USB bus through the VEXT pin to the switching regulator power supply. LTC3456 includes a full-featured USB Power Manager to take advantage of USBHP and SUSPEND pin to control the state of the power flux from the USB pin. USB pin current is flowing through the precise limit of 100mA or 500mA (depending USBHP pin on the state). By SUSPEND pin pulled high to disable all USB functions.
When must raise two AA Panasonic Lumix Dmc-fx30 Battery voltage (1.8 V to 3.2 V) to generate 3.3 V output, and USB/the wall must be the power (4 V to 5.5 V) to produce the same antihypertensive operation voltage, DC-DC changeover will be a particularly challenging job. LTC3456 through the BOOST and BUCK2 converter finished this task. This is a generated 3.3 V power rail the most efficient way. When the battery or USB/communication from adapter to generate 3.3 V output, LTC3456 realizes the higher than 90% efficiency. The kernel output (1.8 V) is through the BUCK1 (by USB/the wall power to power supply) and BUCK3 (by the Canon Eos-300d Battery to power supply) converter to generate. The unique LTC3456 topological structure of a single inductor available to generate 1.8 V power rail, which saves the cost and space. When from the battery to generate 1.8 V output, it achieved more than 92% efficiency. Table 1 LTC3456 lists the different work model.

Portable devices need to realize from battery power to USB or the wall seamless switching power supply (and vice versa) to ensure the smooth operation of the system. For example, a user is a USB cable to connect the portable MP3 music played on board. If the USB cable is suddenly pulled off from the equipment, the user should be able to continue to listen to music, and won’t aware of any interruption phenomenon. LTC3456 through the realization of switching power supply system and make the desire of seamless become possible. When SUSPEND pin was low electricity from PingLa to high electricity at ordinary times, not with USB power supply. The main output and the kernel when switching output in both showed less than? % of total deviation, and thus realizes the processor core and periphery circuit to the seamless switch.

Is it Worth Adding a Battery Grip for the Extra Expense?

 Each Canon battery grip is different. You will need to choose the right one for your camera.

If you own either a Canon 550D , Canon 500D , Canon 350D  or the Canon 5D Mark II ,, you have probably either got or have considered adding an additional Canon Battery Grip.

Some forum posts that I have read state that they are a waste of money that could be better spent on a lens or other more useful accessories…I tend to disagree, as do many other Canon users.

It all depends on 3 things really;

• Your disposable cash
• How much you use the camera and what for
• And the size of your hands

Also think about this. Why do most, if not all professional digital or film SLR’s have the huge camera packs actually built into the body if they are a waste of money?

Personally, when I first bought the Canon EOS 6D a few years ago now, the first accessory I got with it was the Canon battery pack. The camera was fairly large without it but always felt to me like something was missing. I have used pro film SLR’s in the past and the canon 5D just didn’t feel right.

Once I had added the Canon 50d battery grip, all was well in my world once more. I wondered why Canon didn’t make the cameras with the grip already attached and then realised that there has to be more distinction between the “semi-pro” range and the professional cameras (plus it is a nifty marketing ploy I must admit).

The additional grip for me adds certain functionality that I just couldn’t do without, the main one being the vertical shutter release and controls. When you are shooting heavily with little time to play around, it is nice and so less awkward to be able to throw the camera into a vertical “portrait” position and feel just at home as in “landscape” mode.

This was all emphasised even more when I upgraded to the EOS 350D in around 2004/2005 which Canon had made even smaller. In my hands it felt almost like a toy so the Canon battery grip 500d was fitted immediately. Once again, all was well.

The way I tend to carry a camera has changed too. I very rarely have it around my neck and use the strap to wrap around my wrist for security (from dropping as well as “snatch” theft). I tend to hold it by one of the grips, either the built in side grip or the added battery pack grip.

 As you can see from this image, by adding the Canon battery grip, both grips become the same length, again making life just a little easier. Also, don’t forget one very important point…what the grip is really for…adding extra battery power!

The additional battery life in your camera could be the difference between getting all the shots and just most of the shots…quite an important issue if you shoot weddings etc.

If you haven’t tried your camera with a grip, give it a go or better still just buy one, you won’t be disappointed and it will add to the resale value when you come to upgrade and lets face it, they look good too! The best prices I have found, and where I bought my grip for the EOS 7D was B and H. They have just about every accessory you can think of at the best prices, and they deliver on time too
