Problem: USB charging is slow
Charging a device using the UPS's USB charger is slower than the device's original USB chargerThe amount of power a device draws depends on its compatibility with the USB Battery Charging Specification 1.2. Compatible devices can draw more power than devices that are less compatible. For devices that can charge using input greater than 1A make sure that the device is connected to the 2.4A USB charging port.
Problem: Battery charging is slow
The charging time of battery varies depending on the charging connection.Charge the battery inside the UPS for best results. Using the micro-USB port to charge the battery will require more time. The speed is also dependent on the type of USB charger. Some USB chargers support 1A and others up to 2.4A. More powerful chargers will reduce the time required. USB ports on a PC can also charge the battery but older PCs only support 500mA which will result in even more time to charge.
