The SISpower-C powerbanks consist of the latest electronic components, with QC3.0 USB-A Out and Type-C In/Out. The Tesla Li-Ion batteries provide enough power to reach 5V/2A, 9V/2A and 12V/1.5A (max. 18W) at both outputs, which is very special for this compact design. The electronics are ideally tuned for solar applications and allow simultaneous charging and discharging of the battery. In addition, the electronics smooth out voltage fluctuations during solar operation and ensure maximum yield.
