Match capacity and format to your routine

Nominal capacity refers to the internal battery. It does not establish an exact number of full phone charges: energy conversion and phone use affect the result. Compare a higher-capacity option with the dimensions and weight listed for that particular model.

  • For 10,000mAh options, compare PPB5114 and PPB5124. The current PPB5114 lists two USB-A outputs; PPB5124 lists USB-A and USB-C outputs.
  • At 20,000mAh, PPB5212 lists USB-A and USB-C outputs, while PPB5213 includes built-in USB-C and Lightning cables.
  • At 30,000mAh, compare PPB5303 with the built-in-cable PPB5304. Use the product cards to open the specific colour offered for each model.

Check charging power and port roles separately

A USB-C connector alone does not establish USB PD or PPS support. Check whether the port is an input or output, your phone’s charging requirements and the cable. A rating for one port does not establish the rating of every port or the shared output when charging several devices.

The listed PPB5303 output limits are up to 20W over USB-C and up to 22.5W over USB-A. These are distinct port ratings, not a claim of 22.5W USB PD. This description follows the offered versions’ specifications; we have not physically tested these units.
