Inside the aluminum housing is a powerful 2600mAh lithium-ion battery that you can use to charge your smart phone or smart watch. It works very simply: just plug one end of the USB cable to charge your device and plug this stick via micro-USB to charge it up.

Just pop the prongs out and you are good to go. The actual device has a rubbery matte finish and four LED indicators to tell you the battery percentage.

Fluxmob Bolt Battery + Charger - Best Power Banks of 2015

It’s a battery backup and a wall charger. It’s a Kickstarter success story. It has a really nice design with matte rubber finish which definitely feels good in hand and that two-tone look with sharp edges makes it look a bit minecrafted. It is basically designed to be a time saver by daisy chaining this charging experience and letting you charge your iPhone and battery at the same time. It has a 3000mAh battery making the bolt one of the smaller (yet stylish and compact) solutions that we have seen in a long time.
