Powerbank 10000 Mah Portable Phone Charger
The mobile power bank is usually designed to be light, small and easy to carry to facilitate mobile use.
After the charger is fully charged to the mobile power supply (usually designed to be fully charged for 3-5 hours), connect your digital device with the appropriate connector or directly connect the USB On-the-Go (USB-OTG) portable device with the USB cable, and the mobile power supply will start to power or charge your digital device after automatic detection or simple switching.
Some companies will design the product as a mobile power supply "with video rack", which is greatly convenient for customers to provide charging functions while watching movies on the road.
