Never lose power again with these top battery packs

Planning a vacation? Going to bring your laptop, smartphone or tablet along? You will want to get an external battery pack. These portable units let you plug nearly any device within them. The battery pack will charge them when they start running out of juice. But which external battery packs are best? The tech site Lifehacker recently asked its readers to rate the top battery packs. Here are their three favorites.

Anker Astro

Lifehacker readers chose the Anker Astro as their favorite line of external battery packs. Anker manufactures three packs, the 3E, Pro and E4 versions. Each of these devices are given praise for the powerful charging ability they have. The devices also score points for their portability and reasonable prices.

New Trent

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

Energizer XP

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