Planning on doing much traveling over the Holidays? If you are, and you have a few devices for yourself or a whole family to keep entertained or charged up during long flights or drives, then you're going to need a battery pack. These portable battery packs can be incredibly useful, not only will they keep smartphones topped up for emergencies or navigation purposes, but they can keep a tablet or two charged as well, keeping the little ones entertained and reducing the "are we there yet?" questions from the back seat. Anker's E7 Astro is on sale right now for just $59.99 over at Amazon.
Now, if that sounds a lot of a battery pack, which we suppose it is, just remember this has a capacity of 26,800 mAh. The average Android smartphone has around 3,000 mAh in it and a tablet somewhere in the region of 6,000 mAh or so. This means that this compact, yet admittedly weighty, battery pack will keep your smartphones and tablets charged for a couple of days or so and definitely keep you topped up during a long-haul flight or lengthy drive cross-country. What's more, this will charge three different devices at the same time outputting around 3.0 Amps a port, that's some serious power and should charge most modern smartphones in a couple of hours from zero to full.
