The Lenmar Helix Battery Pack: Powerful, But Not Powerful Enough [Review]



External battery packs are one of the least sexy aspects of the mobile age. They’re the equivalent of the plastic gas can in the back of your trunk: stinky, unsexy, and probably empty when you need it.

Category: Battery pack
Works With: iPad, iPhone, iPod touch
Price: $100

Lenmar’s Helix battery pack isn’t particularly sexy, but it doesn’t smell (despite the “Undead Power” branding, which implies putrifying flesh) and it’s unlikely to be empty when you need it: it has a massive 11,000mAh battery inside, capable in theory of charging a third- or fourth-gen iPad from 0% to full. All in a battery pack not much bigger than a deck of playing cards.
