iRobot Roomba 800 Series vacuum
Welcome to a Vacuum Cleaner Battery specialist of the iRobot Roomba Battery
iRobot has introduced its latest Roomba vacuum, the Roomba 800 Series. With this latest iteration of the cordless, self-operating vacuum, the company has elected to get rid of bristles in favor of AeroForce technology, which is said to pick up 50-percent more dirt and other trappings than previous Roomba models. There are two rotors in place, each made of rubber with treads, that spins to break up and grab debris. We've got a video of the system in action after the jump.
With the new design, iRobot says jams and hair clogs are nearly impossible, and that overall cleaning is greatly improved over previous models. Particles -- such as allergens -- are trapped in an air filter, keeping them from being dispersed around the room, while the angle of the rubber treads and the system's design both allows for maximum debris churning and optimal suction on the floor's surface.
Aside from the changes made to the 800 Series with battery like iRobot Roomba 80501 Battery, iRobot Roomba 500 Battery, iRobot Roomba 510 Battery, iRobot Roomba 530 Battery, iRobot Roomba 560 Battery, iRobot Roomba 580 Battery, iRobot Roomba 600 Battery, iRobot Roomba 700 Battery, iRobot Scooba 5800 Battery, iRobot Scooba 5900 Battery, iRobot Scooba 6000 Battery, iRobot Scooba 350 Battery, it largely works the same way you'd expect, with the vacuum offering the press-to-clean-button in the center. Owners can schedule cleaning times for when they're not home, and a combination of software and sensors allows it to travel around a room without sucking up stray wires or falling down stairs. When finished, the vacuum returns to its cradle.
Said Roomba 800 Product Manager Max Makeev: "With the Roomba 800 Series, we developed a highly efficient cleaning system that will revolutionize robotic vacuuming. From the air flow accelerator to the high efficiency vacuum, everything about AeroForce was designed to multiply and maximize cleaning performance. In fact, the Roomba 800 Series has a 5x more powerful vacuum that removes up to 50-percent more dirt, debris, hair, and harmful allergens than previous Roomba models."

Nikon D7100
Welcome to a Battery Grip specialist of the Nikon Battery Grip
In a long line of expert-level APS-C SLRs, the Nikon D7100 has arrived as a descendant of the D7000—a favourite of Nikon aficionados and a hit among reviewers—while also taking over from the ageing Nikon D300s, which is still hanging around despite being released in 2009. As a model that seeks to accommodate both enthusiast consumers and pro users, the D7100 is being billed as the best ever Nikon APS-C SLR. So does it live up to expectations?
Over time, Nikon's design has been getting gradually rounder, with curvier corners and a generally less stocky kind of look. Even though the D7100 is slightly larger than its predecessor, it's actually a bit lighter as Nikon has used more more magnesium alloy, notably on the top of the camera. The "100% magnesium" frame seems to be reserved for Nikon's higher-end models for the time being. As usual, the finish is very high-quality and the controls all work well, with nicely notched dials and pleasant-to-press buttons. Our only slight regret is that the shutter-release has quite a long press. On the other hand, we very much like the reworked grip handle, with a new curvier design that's comfortable to hold no matter how big or small your hands. You won't be able to complain about grip such as Nikon MB-D80 Battery Grip, Nikon D5000 Battery Grip, Nikon EL4A Battery Grip, Nikon MB-D10 Battery Grip, Nikon MB-D11 Battery Grip, Nikon MB-D31 Battery Grip, Nikon MB-D51 Battery Grip, Pentax BP-K7 Battery Grip, Pentax K10D Battery Grip, Sony VG-B50AM Battery Grip, Sony VG-B30AM Battery Grip here!
The general controls and layout haven't changed too much in the D7100. New features include a lock button in the middle of the mode-selection dial, a Live View button in the middle of the photo/video mode switch and an extra button down the left-hand side of the screen. This new and rather strangely named "i" button offers direct access to the camera's main settings.
The screen, however, has changed quite a bit. First of all, the two little clips for attaching a plastic screen protector have gone. Today's Gorilla-Glass-style protective finishes are clearly considered sufficiently robust to do away with such "unsightly" add-ons (even if they are very practical). It's like the end of an era! But nostalgic Nikon users may find solace in the screen's boosted specs. The screen has been upped from 3" to 3.2" in size and boasts 1,229,000-dot definition thanks to the new RGBW backlighting system (Red, Green, Blue, White) with white pixels on hand to push up the brightness. Plus, our tests found that screen calibration is spot on in this DSLR. We measured the average colour temperature at 6468 K, the average Delta E 94 (colour fidelity) at 2.1 and the gamma bang on 2.2. If we really wanted to nit-pick we could say that blacks are a bit too light and whites are a bit too dark, but these "faults" aren't really problematic. In fact, they actually help improve the screen's readability!
The D7100 has a good range of connections, with microphone and headphones ports, a USB connection (but still no sign of USB 3.0), a HDMI port, a remote control port and two memory card slots (SDXC-compatible). The memory cards can be filled up sequentially one after the other, or used in parallel to back up shots or to save different formats. For Wi-Fi you'll need to pick up the optional WU-1a adapter. Similarly, a separate module (GP-1) is available for GPS. And anyone who's not satisfied with the built-in flash can pick up the WR-1 wireless remote controller—a snip at £650!
The menus are typically Nikon-esque. Packed full to the brim with settings and detailed options, they can feel quite dense. You may need to give up your bed-time novel for a while in order to get through the instruction manual. But the upside is that absolutely everything can be user-adjusted, which is great for users looking to set up their SLR to suit particular preferences. And that makes perfect sense when you think about who this camera is aimed at. Otherwise, we still think it's a shame that the ISO AUTO option isn't active by default, and that you still have to go into the menu to delete several shots at once (that doesn't make editing any easier).
Canon unveils EOS T5i and Rebel SL1
Welcome to a Battery Grip specialist of the Canon Battery Grip
If you haven't already come to grips like Canon BG-E2N Battery Grip, Canon EOS 350D Battery Grip, Canon EOS Rebel XSi Battery Grip, Canon Eos 5D Mark II Battery Grip, Canon EOS 7D Battery Grip, Canon EOS 550D Battery Grip, Canon 60D Battery Grip, Canon EOS 1100D Battery Grip, Canon 5D Battery Grip, Nikon D60 Battery Grip, Nikon D3000 Battery Grip with the fact that Canon won't be releasing a mirrorless camera with DSLR-like performance, you might as well cut your losses now. Instead of replacing the sluggish EOS M with a compelling shooter, the company has decided to focus on shrinking its DSLR. The result, the EOS Rebel SL1, is the world's smallest Digital SLR. SL stands for "super lightweight," which seems appropriate, given that it tips the scale at just over 14 ounces, yet the camera still accommodates EOS lenses, such as the new EF-S 18-55mm IS STM optic that ships in the box. There's an 18-megapixel APS-C CMOS sensor, DIGIC 5 image processor, a 1.04M-dot fixed touchscreen, a new hybrid autofocus and standard 9-point AF. It offers sensitivity ranging from ISO 100-25,600, can capture 1080p video at 30 or 24 fps, and it includes a built-in mono mic, along with a stereo mic input jack on the side. Jump past the break for our hands-on.
We spent some time with a pre-production SL1, and while we were able to shoot a bit, we weren't permitted to walk away with any sample images. From a performance perspective, the camera seemed quite speedy, with accurate and fast AF both through the viewfinder and in live view mode. There's a typical assortment of buttons and dials, but due to the reduced footprint, Canon had less room to work with -- as a result, things can feel a tiny bit cramped. Despite the size, however, the grip seemed sufficient, and the camera was comfortable to hold. We also had a chance to check out Canon's new Rebel T5i, which, by the company's own admission, is virtually identical to its predecessor, the T4i. The body finish is slightly different and there's now an option for an 18-55mm STM lens kit, but besides a few mode dial tweaks and some even less significant additions, there's really nothing else to speak of here.
As for pricing, the Rebel SL1 will cost you a bit more than many mirrorless models. It's set to retail for $650 (body only), or $800 with the new 18-55mm STM lens. The T5i will run you $750 (body only), $900 with the 18-55mm optic or $1,100 with an 18-135mm lens. T4i owners looking to build out their collection a bit can pick up that 18-55mm lens by itself for $250 -- unless you plan to buy that optic, however, you might as well snag last year's model if you can find it on sale, given that it's due to be discontinued after all of these new EOS products begin shipping in April. Flip through the gallery for some comparison shots with both the T5i and SL1, then take a closer look at that latter model in our hands-on video below.

Lenovo IdeaPad K1 review
Welcome to a Laptop Battery specialist
of IBM Laptop Battery First post by: www.laptop-battery-stores.com
Let's do a roll call, shall we? Who doesn't have a Honeycomb tablet to shill in the states? Acer, ASUS, Motorola, Samsung, Sony, and Toshiba all have something to their names, with Dell possibly bringing its China-only Dell Streak 10 Pro here too. Until now, Lenovo was one glaring exception. The company already had a head start selling the LePad tablet in China, but it was only last month that it announced not one, but two Honeycomb slates for the US market: the IdeaPad K1 for mainstream consumers, and the ThinkPad Tablet for business users (and a fair share of geeks, too). Now, we could easily roll our eyes at how saturated the market for Android tablets is becoming, but Lenovo isn't just any old OEM. The brand has won such an avid following that we bet the company could have essentially slapped its name on a plain-Jane black slab and waited for loyal fans to line up.
In fact, though, you're in for a bit more than name recognition. The K1 goes after mainstream consumers with a winsome design, sure, but also a software package designed to make Honeycomb easier to use, and to help ensure that flummoxed, low-tech users don't have to spend too much time downloading apps out of the box. What's more, it ships with Android 3.1 and has a two-cell battery like IBM 08K8199 Battery, IBM 08K8198 Battery, IBM 08K8197 Battery, IBM 92P1075 Battery, IBM ThinkPad R40 Battery, IBM ThinkPad R32 Battery, IBM 02K7054 Battery, IBM ThinkPad A20 Battery, IBM ThinkPad A20M Battery, IBM ThinkPad A21M Battery that promises up to ten hours of battery life. Oh, and the 32GB model rings in $499, undercutting the 32GB iPad 2 and Samsung Galaxy Tab 10.1 by $100. But is that enough for it to stand out? Let's see.
Like so many other Honeycomb tablets, the K1 packs a 1GHz NVIDIA Tegra 2 SoC. Mainstream consumers might look at us cockeyed if we told them the performance could be zippier -- for those folks, the performance should be plenty fast. But more discerning techies will likely notice some lags when minimizing and opening apps. The screen was also often slow to switch orientations as we flipped from landscape mode to portrait and back, and more than once the display was unresponsive, leaving us tapping multiple times before the tablet did what we wanted it to. In general, we tend to say that all Tegra 2 tablets have some obvious performance limitations, but the K1 felt pokier than others we've tested. Indeed, its score of 1,448 in the Quadrant benchmark falls short of the 1,546 and 1,584 that the Thrive and 10.1 notched. And while we try not to put too much stock in benchmarks, we think these numbers are telling, given our anecdotal experience with the device.
Also, not to beat a dead horse, but at some point during our testing, we took a break to play with the 10.1, and immediately breathed a sigh of relief. It's hard to tell how much of that was the 10.1's solid-yet-lighter build, the bright display, or the quick performance, but boy, did we miss it. The 10.1 is markedly faster, and the difference becomes painfully obvious when you play with the two side by side. The 10.1 is quicker to respond to taps and swipes, its screen rotates faster, and it opens and minimizes apps more briskly.
| Benchmark | Score |
| Quadrant | 1,448 |
| Linpack | 32.77 MFLOPS (single thread) / 61.33 MFLOPS (multi-thread) |
| Nenamark 1 | 30.1 fps |
| Nenamark 2 | 19.6 fps |
| Vellamo | 945 |
The K1 has a 2-cell, 7400mAh battery that promises up to ten hours of battery life -- the same claim made by the iPad 2. In our standard Toshiba PA3641U-1BAS Battery rundown test (movie looping, WiFi on), it lasted eight hours and twenty minutes, matching the Motorola Xoom and falling about ten minutes short of the TouchPad. But it doesn't approach the Galaxy Tab 10.1's ten hours nor the iPad 2's ten and a half, which seems like a problem given that the K1 is markedly chunkier. If a tablet's going to be bigger, we want it to make up for it with longer battery life and / or more robust performance. The K1 doesn't quite do that on the longevity front, though it did have a much better showing than the Thrive, which lasted just six and a half hours in the same test.

| ASUS EeePad Transformer | Ran a different test |
The IdeaPad K1 is cute, (relatively) affordable, and easy to use, and we know it'll be a sensible choice for some shoppers. We're just not sure that's you, our dear, tech-savvy readers. See, the K1 has two big strengths: one, it's aggressively priced, starting at $449 for 16GB (granted, that version's not on sale, so if you buy today, it's going to be the $499 32GB model). The other major thing the K1 has going for it is simplicity. Lenovo's tweaked Android 3.1 so that settings are easier to find and apps are a cinch to kill. It also comes with an array of popular apps (or bloatware, if you're cynical). Factor in the attractive design, and we can recommend this, particularly for people with budget constraints, or those looking to give a techie gift to a not-so-techie person. Those things aside, the K1 is heavier than most tablets, and doesn't justify its heft with additional ports, extraordinary battery life or even zippy performance. If you didn't want ports anyway, and know your way around Honeycomb without Lenovo's help (thank you very much), why not just get something thinner, faster, and longer-lasting? Or, you know, at least stick around and see how Lenovo's geekier ThinkPad Tablet fares.

Hewlett Packard Jornada 820
Welcome to a Laptop Battery specialist
of Hp laptop battery First post by: www.laptop-battery-stores.com
It's very rare that you get a piece of kit in for review that makes you re-evaluate what you want from a computer, but the Jornada 820 is one of those beasts.
The first thing to mention here is that the 820 is pushing the limits of what you can actually call a PDA. It's more of a sub-notebook, but then again it runs Windows CE, which is part of the attraction of this device. It brings together the best of both worlds, but more on that later.
The 820 is the top-of-the-range device among the Hewlett Packard (HP) CE PDAs. With dimensions of 246 x 178 x 33mm and weighing in at 1.1kg, it's a lot larger than any of the Windows CE handheld devices on test here, but it is still relatively diminutive when you compare it to a full notebook.
One of the benefits of its larger size is that there is very little compromise when it comes to inputting data. You are presented with an excellent keyboard, that is responsive and has plenty of travel. The good news for those who expect to do a lot of typing is that it is comfortable to use for extended periods. Just below the keyboard you'll find a touch-pad. This is slightly smaller than those you'll find on a notebook, but because the 820's screen isn't as big as that of a laptop, you don't need as much surface area to navigate the screen.
The only problem we found with the keyboard is that it doesn't tilt, so when you're using the device on a flat surface your hands are at an uncomfortable angle. Nevertheless, most people are likely to use the 820 on the move, where you are more likely to be resting the unit on your knees, giving you a better typing angle anyway.
The other advantage of the larger form is that HP can afford to kit out the device with a pretty impressive colour screen. While the CSTN technology used is a little outdated, the screen is bright, displays vibrant colour and offers a very respectable resolution of 640 x 480. The viewing angle, while not amazing, is easily good enough for everyday use. If you're working at a desktop, you can even plug the device into a standard desktop monitor via the VGA port at the rear of the unit.
If you venture round the back of the unit, you'll also find a USB connector nestling next to the VGA port. We tried plugging a Microsoft USB Intellimouse into this and it worked first time without even pausing to load a driver. This was a true demonstration of plug-and-play, but then again there aren't many other USB devices that come with Windows CE drivers. HP says that Y-E Data's Flashbuster-U floppy drive will also work, but we haven't tested this. It's a great shame that you can't make use of the USB connection to transfer files between the 820 and a desktop PC; instead you are stuck with the slower serial option.
To the right of the USB port you'll find the telephone connector for the modem, which is a 56K model. While the modem's performance is not wonderful, it's still a welcome addition. If you feel you can do without the modem, you could always opt for the 820e model.
On the rear you'll also find a 4Mbits/sec IrDA port, which is a nice location for it, as it means you can leave another device communicating with the 820 while you type away at the front of the unit. Other slots and ports can be found on either side of the device. The right-hand side is home to the Compact Flash card slot, the AC port and the serial port, while the opposite side sports the PC Card slot and the battery backup compartment.
The main battery slot is underneath the unit much like a laptop battery such as Hp Pavilion dv9000 battery(Hp dv9000 battery), Hp EV087AA battery, Hp EX942AA battery, Hp Pavilion ZT3000 battery, Hp 337607-001 battery, Hp 337607-003 battery, Hp PB992A battery, Hp PB994A battery, Hp PB991A battery. The only difference is that with the 820 you get a whopping 10 hours of battery life, due to the lack of moving parts and general efficiency of the device.
Synchronising the device to a PC is simply a matter of loading up Windows CE Service 2.2 on the PC and making sure both devices are set to communicate at the same speed. We had no problem transferring contacts and appointments between the device and Outlook 2000.
As far as software is concerned, you get the full Pocket office suite. HP has also included some extra utilities, such as settings applets for the VGA port and the touch-pad. There are also some extras on the CDRom bundled with the device, such as software to allow you to print directly from the 820 and Outside In email attachment viewing software from Inso.
All in all, the Jornada 820 is a joy to use. The keyboard is touch-typing friendly, the screen looks great and the supplied applications take care of all your daily needs. If you were thinking of buying a laptop, but wanted something a bit smaller yet still with a long battery life, the 820 is the machine to go for.
