Power bank data matrix
Every reading below is a manufacturer claim for the exact model revision. Open a figure’s source for its reference and checked date. USB-C input means one standard input connection; combined inputs and proprietary docks are excluded.
Rated Wh describes stored battery energy. It does not predict delivered USB energy or device recharge counts. Blank readings remain unknown; we never infer Wh from mAh using an assumed voltage.
