I have a Pixel 8a, which is certified qi1, and 2 devices that can wirelessly charge it, a baseus battery pack and an ESR phone holder, they’re both certified qi2 (which is backwards compatible with qi1), yet when I charge with them I can at most reach ~2.2W charging instead of the 7.5W advertised maximum for my Pixel 8a.
I don’t understand why that is and if I can even theoretically reach the maximum supported charging power.
If so, how would I test my devices to figure out what their real thresholds are or if there are incompatibilities somewhere?

    If we take only the battery pack into consideration, where it directly takes power from its own circuit and delivers it through the coil it has, I’ve tried with and without case on the phone and it didn’t look like it made any difference, always around that wattage, is it not strange that it wouldn’t even be able to reach half the maximum speed in pretty much optimal conditions?

      That seems strange to me, but it wouldn’t shock me to find that is normal. Tech tends to advertise based on extreme best-case scenarios.

      Despite that, there may well be something wrong with either your charger or your phone. It would be interesting to try a different charger, if you have access to one.
