BatteryRank review
A reasonable choice when attaching a Qi2 magnetic pack to a compatible phone is more useful than a built-in cable. For a universal pocket bank, check the phone’s magnetic alignment and case first; the USB-C path remains the more broadly useful wired option.
Ratings below are manufacturer-claimed. Open a reading to see its source and check date; derived comparisons are identified separately.
Use and carrying fit
Anker rates Qi2 wireless output up to 15W and USB-C wired output up to 30W. The magnetic charging experience depends on a compatible phone or magnetic/Qi2 case; Android devices without magnetic alignment need an appropriate case or ring.
What changes the choice
Wireless output is rated up to 15W, but the magnetic attachment depends on device and case alignment. A non-magnetic case can prevent the bank from attaching as intended.
The US page lists 30W USB-C output profiles while a separate total-output row shows lower values without a clear mode description. The model-specific guide confirms 30W USB-C input/output and 15W wireless output; we use those per-port figures and leave total output unranked.
Before connecting devices
A port’s published maximum and the combined multi-port limit are separate ratings. A device can draw less than the bank’s maximum based on its own requirements and the negotiated charging profile.
Anker’s model-specific guide lists up to 30W through USB-C for input and output. Qi2 wireless charging is a distinct path with a 15W maximum.

Manufacturer claims link to the dated source used for this exact revision. Watt-hours appear only when the OEM states them explicitly; we do not infer energy from milliamp-hours.
Exact-model questions
No. The model-specific guide rates USB-C input and output up to 30W and Qi2 wireless output up to 15W. They are different charging paths.
Magnetic attachment requires compatible magnetic alignment. Anker advises Android users to use a compatible magnetic or Qi2 case; a plain case without a magnetic ring may not attach.
