HP Probook 4535s Notebook Battery

There is nothing worse than running out of battery on your phone. Well, there is, but when it happens it feels like the worst thing in the world.Unfortunately, as advanced as smartphones have become in recent years, battery life is still something they haven't quite nailed. Some will last most of the day, others might get you through most of the evening too, but that's assuming you aren't spending all your time on WhatsApp, or catching Pokemon.Doing either of those, especially the latter will see that bar in deplete. Rapidly. The problem is, while you might be thrilled at having caught Pikachu, if you've missed your last train in doing so and your battery is on 2 per cent, that thrill will quickly disappear, no matter how cute he may be.

That's where battery packs come in. They have been around for years so when it comes to your options, there are hundreds. You'll find small ones that will fit in you pocket but only give you a small bit of extra juice, as well as larger ones that will charge your phone three times over. That's a lot of extra Pokemon playing you could be doing.We've rounded up a selection of the best battery pack options out there to make sure your phone keeps up with you.

Funky interstellar design, customizable lighting and show-stealing displays â”€ dude, you're getting an Alienware. But Alienware's gaming laptops are more than just portable light shows. These are hard-core machines crammed with powerful specs that can take your gaming experience to the next level. OK, now that you've chosen an Alienware, which one is it going to be? Available in 13-, 15- and 17-inch laptops starting at $899, $1,199 and $1,499, Alienware offers several configurations in each size factor that can be further customized at purchase. After a while, all that choice can become intimidating.But never fear, this guide will show you the ins and outs of purchasing an Alienware laptop that suits your tastes in size, display, power and portability. Whether it's the 13-inch and its extreme portability, the slightly beefier and considerably more powerful 15-inch, or the mother of all battleships, the massive Alienware 17, there's a gaming notebook out there with your name on it.

â€‹Gamers who want on-the-go fragging will prefer the tiny terror that is the Alienware 13. Measuring a petite 12.0 x 9.3 x 0.69~1.1 inches and weighing 4.5 pounds, it's the perfect size to stow away in a backpack or a large purse. Despite its diminutive size, the laptop doesn't skimp on the glowing Alienware accoutrements. The glossy 2560 x 1440 touch panel is stunningly vivid with precise detail. In our tests, the screen reproduced an astonishing 206 percent of the sRGB color gamut with a dazzling 292 nits of brightness. Whether playing games, watching movies or looking at pictures, the Alienware 13 is truly a sight to behold.The Alienware 13 also comes in 1080p and 1366 x 768 varieties, but if you can't spring for the OLED screen, go for the 1080p option. Under no circumstances should you even consider the 1366 x 768 model unless you like looking at lackluster color and muddy graphics.

Not too big, not too small, the Alienware 15 is just right. Gamers that want a gaming laptop that's smaller than the massive 17, but bigger than the relatively tiny 13, should consider the 15-inch.The midsize laptop packs a bunch of win under its chassis with great gaming and overall performance, thanks to its 2.6-GHz Intel Core i7-6700HQ CPU and Nvidia GeForce GTX 970M graphics card.If that weren't enough, gamers can expect excellent audio quality, an extremely comfortable keyboard and over 7 hours of battery life when web surfing. Another plus: The Alienware 15's dimensions (15.1 x 10.6 x 0.9~1.3 inches, 7.1pounds) still make it plausibly portable.Cue up the screaming townsfolk because the alien has landed. Decked out in its glowing, customizable lighting, the massive Alienware 17 looks every bit like an alien mothership. Similar to its smaller brethren, you can expect a cushy keyboard and stellar audio. And depending upon the configuration, your new space station can have a gorgeous 4K display.

But when it comes to gaming and overall performance, the 17-inch behemoth can crank things up to 11 depending on whether you prefer Nvidia's GeForce GTX 980M GPU or AMD's Radeon R9 M395X GPU. And if you're really feeling fraggy, there's the overclockable Intel Core i7-6820HK processor. The notebook can also be outfitted with a 512GB PCIe SSD for blistering boot and transfer speeds, which definitely comes in handy when it's time to play. Trust me, no one wants to be waiting more than 30 seconds to start dishing out digital beatings.

When we ran the resource-taxing Metro: Last Light benchmark on the Alienware 17's Nvidia GeForce GTX 980M GPU at 1920 x 1080 on low settings, it ran at a rate of 124 frames per seconds. However, the Alienware 15 and its Nvidia GeForce GTX 970M GPU weren't too far behind at 112 fps. The Alienware 13's GTX 965M GPU produced 69 fps. On the Geekbench 3 synthetic performance test, the Alienware 17's 2.7-GHz Intel Core i7-6820HK CPU helped it score 13,906. The Alienware 15 (2.6-GHz Intel Core i7-6700HQ CPU) and the Alienware 13 (2.5-GHz Intel Core i7-6500U) achieved 13,494 and 6,816, respectively.

On the File Transfer Test, the Alienware 17 (512GB PCIe SSD with a 1TB, 7,200-rpm hard drive) had a transfer rate of 508.8 megabytes per second. Equipped with 256GB PCIe SSDs, the Alienware 15 and the Alienware 13 notched 201.1 and 179.6 MBps, respectively.In addition to their out-of-this-world design, beautiful displays and booming audio, Alienware laptops are known for having impressive battery life â”€ for gaming rigs at least.The Alienware 17 lasted 6 hours and 7 minutes on our battery test (continuous web surfing over Wi-Fi), while the Alienware 13 with the OLED display clocked in at 5:38. But the Alienware 15 ran 7:13, which is practically unheard of for gaming notebooks.

Alienware's Graphics Amplifier ($199) can transform any of the company's current fleet of gaming laptops into a powerful desktop. Depending on which desktop graphics card you put in, your Alienware 13, 15 or 17 can go from awesome to kick-ass in a flash. When we plugged a Nvidia GeForce GTX 980Ti GPU ($499) into the little black box, the Alienware 17's Metro: Last Light scores jumped to 62 fps at 1080p on ultra. That's a big improvement over the 37 fps the laptop obtained on its own. In addition to producing better frame rates for your traditional PC games, the graphics amplifier is also the gateway to virtual reality. Provided your laptop has at least an Intel Core i7-4700HQ processor with 8GB of RAM, all you need to start is the right desktop graphics card (minimum: Nvidia GeForce GTX 970 or AMD Radeon R9 290) and either an Oculus Rift or HTC Vive, and you're good to go.

If you've got your eye on the Alienware 13, I'd highly recommend checking out the amp. Having a superportable gaming system is great when you're traveling. However, when you get home you're going to want something with a bit more oomph. Alienware 15 and 17 owners should check out the amp if they want to do VR without spending too much money.It pretty much goes without saying that when it comes to power, the Alienware 17 is the cock of the walk. However, don't underestimate the smaller rigs, as they beat systems with similar specs in their weight class. The Alienware 13 is a great choice for gamers who want to play Doom or Rise of the Tomb Raider while they're on the road. The Alienware 15 takes some of the best aspects from the 13 and 17 and combines them into a midsize gaming dynamo that is my top pick for an all-around gaming laptop.

It's not a stretch to say that Dell's XPS laptops are some of the best all-around laptops on the market today. The 13-inch Dell XPS 13 has remained our top consumer notebook recommendation for well over a year, thanks to its unbeatable combination of light weight, long battery life, vibrant screen and impeccable style.However, one size doesn't fit all. The XPS 13's big brother, the Dell XPS 15, has a larger display that's available with a 4K resolution, optional Nvidia graphics and a quad-core processor. To help you decide which Dell XPS is right for you, we've pitted the two Ultrabooks against each other in a five-round battle, comparing their design, screen, battery life, performance and value.

Aesthetically speaking, the Dell XPS 13 and 15 are nearly identical. Both have the same silver-colored lid and bottom, black sides, and a luxurious soft-touch, carbon-fiber deck that has a subtle gray and black checkered pattern. The laptops also share Dell's nearly bezel-less InfinityEdge Display, which is their most impressive design flourish but also forces the webcam into an awkward position, right below the screen.The base model of the XPS 13 weighs just 2.7 pounds and is only 0.6 inches thick at its thickest point, but tapers down to 0.33 inches at the front lip. Adding a touch screen increases the weight to 2.9 pounds, which is still far lighter than some 13-inch laptops.

Owing to its larger size, the XPS 15 is quite a bit heavier than its little brother, tipping the scales at 4.4 pounds. However, that weight is very light for a laptop with a 15-inch display; competitors such as the MacBook Pro (4.49 pounds) and the Asus ZenBook Pro UX501 (5 pounds) weigh more. The XPS 15 is just 0.66 inches thick at its thickest point, nearly identical to the XPS 13, and tapers down to 0.45 inches.Winner: Dell XPS 13. If portability matters most to you, there's no doubt that you'll want the smaller laptop. However, the XPS 15 is impressively light for its size.
