PowerTrek is the ultimate charger for any smartphone! It includes a 9000 mAh battery and built-in charging cables, so recipients are never left searching for the right cable. To charge a phone or other USB-powered device, users simply slide out one of the built-in charging cables included (MFI Apple Lightning tip and Type-C tip), connect the device and press the power button. Power will instantly start to transfer and the LCD lights on the side will indicate the battery level. Users can charge up to four devices simultaneously. When the 4.35" x 3.05" x 1.04" PowerTrek needs to be recharged, either of the two methods to recharge can be utilized. It features fold out wall plug and comes packaged in a black EVA case. Custom packaging options are also available.
