Thin, flexible and half the weight of monocrystalline panels, the Omnicharge 20W Solar Panel is designed to charge the Omnicharge Omni 13 and Omni 20 power banks. Its 21% conversion efficiency rate is near the top of the range for consumer solar panels. The thin film solar cells can be bent without cracking the panel, and they will even work with minor damage. The panel's DC barrel port produces a maximum 8V/2.5A, and its USB output produces a peak 5V/2.4A.
