Moshi's IonBank 10K is a rechargeable portable battery that can rejuvenate the life of your mobile device. This mobile charger sports 10,000 mAh, enough to charge your smartphone multiple times or extend the battery life of your tablet an additional 7-8 hours. Utilising Moshi's DPS (Dynamic Power Sharing) technology, IonBank intelligently detects and delivers the optimal charge rate to each connected device. The two USB ports have a combined output of 18 watts to allow for the simultaneous charging of two iPads. Unlike typical lithium-ion battery packs on the market, IonBank uses higher grade lithium-polymer cells for greater reliability and longevity. Simply plug your IonBank into any USB wall or car charger to recharge.
