Plugs Into an AC Outlet to Charge Itself and Your Mobile Devices at the Same Time
This is a portable power bank you can take with you to charge your devices at work, on the train, at a convention or at the airport. But it also features a NEMA 1-15P plug that connects to any standard power outlet. Plugging the power bank into an AC outlet turns it into an efficient wall charger that not only charges its own battery to full capacity, but charges up to two connected mobile devices as well.

2 USB Ports
A USB-A port and a USB-C port provide a total of 5V 2.4A (when connected to an AC outlet) or 5V 3A (DC power) to charge your devices, including Android, Apple and Windows.

Protects Your Expensive Devices During Charging
Comprehensive safety features ensure worry-free charging of mobile devices. The power bank provides short circuit, over-voltage, over-current, over-charge and over-discharge protection.
