Small in size, big on power! The PD101 10000mAh Power Bank can deliver a massive 30W of energy and can be used to recharge a MacBook Air. Thanks to its Power Delivery function, this power bank will fast charge your compatible iPhone from 0% to 50% in up to 30 minutes (when used with a MFi Type-C to Lightning cable - not included). Also, the QC 3.0 USB port will help you quickly charge another compatible device. When the LED indicator shows a low energy level, you don't have to wait an entire day for the PD101 10000mAh Power Bank to get back at 100%. Due to the rapid recharge function, full recharge takes up to 3-4 hours through the Type-C PD port (when used with a PD wall charger and a USB-C to Type-C cable). Protection functions keep your device safe from short circuit, overcharging, overdischarging, overcurrent.
