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 a suitable connector or directly connect the USB On-the-Go (USB-OTG) portable with a USB cable Type equipment, the mobile power supply will start to power or charge your digital equipment after automatic detection or simple switching. Some companies also design the product as a mobile power bank with a “video stand”, which greatly facilitates providing customers with the function of charging while watching a movie on the road.
