The most portable battery on the market that you can take it with you wherever you go due to its small size so it can fit in the smallest place in to your luggage or in your backpack. With an ultra-compact design and high power storage (20,000mAh), the PD702 external battery can rapid charge your compatible iPhone from 0% to 50% in 30 minutes (when used with an MFi cable Type-C to Lightning - not included), even if it has half size of an iPhone 13 Pro Max. It can deliver a massive 22.5W of energy and can be used to charge two devices at the same time thanks to its QC 3.0 USB port and the Power Delivery function(PD 3.0 20W). Due to the rapid recharge function, full recharge takes up to 6-8 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.
