The Jumpr Fit 6 provides double the battery capacity of the Fit 3 without sacrificing size or weight. This 6,000 mAh power bank gives you 2-3 phone charges and up to 1 charge for most tablets, yet is still small enough to slip in a jacket or coat pocket. And just like the other batteries in the Fit Series, this battery comes with dual tethers so you can charge both Lightning and Micro-USB devices . Gray.
