Now have power bank, to give an extra charge to the 4G wifi mobile router E5573 which runs approx 4-6 hours, so i have backup for a
at least 12 hours if parked at hotel or car park and can safely monitor the car... noticed when usb cable from car console whilst running car into power bank and connected
to 4G wifi router, it will not charge it unless you have the usb cable disconnected from car usb console, then it will show 2.1 amp
charge to the 4G wifi router... my power bank has two out slots with different amps available.
