As Android tablets and smartphones gain more features and become almost necessary in day-to-day life, they also begin to consume more power and we’re less able to tolerate a dead battery on one of our devices.
Enter the mobile battery pack, which can extend your device’s battery life by several full charges or several hours, depending on the energy demands of different smartphones or tablets by manufacturers like HTC, Samsung or Google.
Here are 10 best battery packs for Android phones and tablets that could save you from a flat battery while you’re on the move:
1. MyCharge Peak 6000 Rechargeable Power Bank
As its name implies, the MyCharge Peak 6000 rechargeable battery inside the unit is rated at 6,000mAh. That’s around double — or even triple — the capacity of smaller, more pocket-friendly chargers, and the Peak 6000 is pretty beefy, weighing in at 8.5 ounces.
As an added bonus, the Peak 6000 also talks to you, thanks to a built-in speaker. A female voice tells you that the unit is charging when you plug it into the wall. The voice also announces when you’re charging a device. And finally, when you press the button to see how much battery power remains, it’ll let you know just how full it is (the four LED lights will also tell you).
The MyCharge Peak 6000 is sort of the Swiss Army Knife of portable battery chargers, with built-in connectors for iOS products, Android devices, and a host of other products.

3. Veho Pebble Battery Charger
The Veho Pebble Battery Charger is capable of adding somewhere around 1,250 hours of standby to most smartphones. Or 125 hours of continuous music playback if you like spending your time without power listening to music.

9. Sanyo eneloop Mobile Booster
Sanyo’s eneloop Mobile Booster sports a compact form-factor, a sleek and attractive all-white design, and the imprimatur of Japanese maker Sanyo’s brand of rechargeable battery technology. But is such a small device capable of delivering enough charge to tablets and smartphones?
As PC Mag’s review noted, the Sanyo eneloop Mobile Booster certainly strikes the right balance among looks, portability and functionality. That’s why the magazine bestowed its Editor’s Choice Award on the device. But it can’t reliably charge certain power-hungry smartphones and tablets, like the HTC Thunderbolt or the HTC Evo. However, it did add more than five hours of video playback to an iPad 1 on a single full charge.
Sanyo’s eneloop Mobile Booster also sports a highly intuitive user interface, consisting of just one blue LED and one button. To start charging a device, just connect it to the Mobile Booster and hit the button. The blue LED will glow, and it starts delivering charge to smartphones and tablets.
10. Energizer XP4001
What could be a better match for your tablets and smartphones on the go than an Energizer mobile battery pack? That’s the premise behind the Energizer XP4001, which is designed to be a balanced battery pack to meet most mobile needs, manufactured by XPal Power under the Energizer brand.
The Energizer XP4001 measures 5.2 by 3.2 inches, is 0.6 inches thick, like the Iogear GearPower Mobile Power Station, and weighs 5.3 ounces. It sports two USB ports for simultaneous charging of smartphones or tablets, and they actually deliver output accordingly. One port is marked ‘phones’ and the other ‘pads’. The former delivers 500mA of charge while the latter delivers 1.5A.
As PC Mag noted in its review, the Energizer XP4001′s more powerful ‘pad’ port was capable of charging an iPad 1 and high energy-consumption devices like the HTC Evo and HTC Thunderbolt. It managed to add nearly five hours of video playback time to an iPad 4. PC Mag concludes that the Energizer unit is a good value alternative to the Sanyo eneloop Mobile Booster for charging any of your smartphones and tablets on the go.
