Yes the Power 1100 can charge devices as it is being charged through one of our Solar options. Please note: When charging through the rear DC input port, the USB-C and USB QC 3.0 ports will be deactivated due to the design of the circuit board. All other ports will work. If you need to charge your Power 1100 while also using the USB-C or USB QC 3.0 ports, the front DC output ports will also allow charging using solar or the provided AC adapter. When charging using the front DC output, the remaining DC output ports may not be used for other loads.
