The massive power of 20,000 mAh gives your iPhone XS over 5 charges, your Galaxy S10 almost 5 full charges, over 4 charges for your iPhone 11, and over 2.5 charges for your iPad mini 5. PowerIQ technology combined with powerful VoltageBoost technology delivers the fastest and, thanks to the convenient trickle charge, the safest charge for almost any device. Two USB ports guarantee you top-speed charging for two devices at once. (The USB-C port is not designed to charge other devices.) You have the flexibility to recharge PowerCore via USB-C or Micro-USB. It takes about 10 hours to charge your powerbank with a 10W power supply and about 20 hours with a 5W power supply.
