Θ Boost 8400

PUMP UP THE POWER

Never be caught powerless again. This super-slim, super-powerful backup battery pack features a rechargeable 8400mAH lithium battery for long-lasting reliable power—whether you’re on a plane or at the park.

DOUBLE UP

The Boost 8400 features a Micro-USB DC input to use with most smartphone chargers and two standard 2.1A USB ports so you can charge two devices (two smartphones or a smartphone and tablet) simultaneously—with a combined output current of 2.1A.

TRIPLE PLAY

When the Boost 8400 is all charged up, it packs enough power to charge most smartphones three times and can even charge tablets—so every device gets the power it needs.

SHAKE IT UP

Just give the Boost 8400 a quick shake and the LED charge indicators will let you know how much battery charge you have left.

PALM SIZED

So small, so sleek, so powerful. Fits perfectly in your pocket, purse or palm for an anytime, anywhere power boost.
