No longer do you have to worry that you forgot to charge your phone overnight or that your battery might die while you are enjoying yourself at a picnic, beach, hike, etc. UME chargers provide a full 0% - 100% charge up to 2x over. Every UME Power Bank comes equipped with a Micro USB charging cable which is compatible with all the smartphones around. Portable devices with proprietary connections (such as iPhone) require their original USB charging cable. Our aluminum shell provides an unprecedented level of durability not found on similar products. Inside the UME Power Bank are a pair of Polymer Batteries. We rigorously test these chargers to ensure that they provide the most efficient charge possible. Most modern day smart phones have batteries that range from 1000 to 2500mAh.
