Keep the power with these battery packs

What’s more frustrating than seeing your smartphone or laptop slowly but steadily run out of power as you travel? Fortunately, you don’t have to put up with this. That’s because external battery packs let you plug just about any tablet, smartphone or laptop into them. The battery packs power your dying devices. But which external battery pack to pick? The Lifehacker Web site asked its readers to rank their preferred battery packs. Here’s what the readers had to say.

Anker Astro

The Anker Astro tops Lifehacker’s list because of the immense power it holds, with the 3E, E4 and Pro versions each supplying some serious oomph. Lifehacker readers pointed to these models’ portability, small size and reasonable price points.

New Trent

New Trent’s external battery packs – the iCarrier and iGeek – both scored high with Lifehacker readers, too. These models, too, hold a lot of power, and the devices offer an easy-to-read indicator light that lets you know easily how much charge the battery pack has.

Energizer XP

Energizer is a big name in batteries, so it’s little surprise that its XP series of external battery packs ranks so high among Lifehacker readers. One of the greatest selling points? These units include a wide variety of tips and cables that permit you to charge practically any phone available, even older models.
