I’ve also tested the following:
- USB hub with Fairphone USB-C cable (USB hub to USB-A to USB-C)
- USB hub with TOPK magnetic USB-C cable (USB hub to USB-A to USB-C)
- Fairphone charger with TOPK magnetic USB-C cable (EU powerplug to USB-A to USB-C)
In all three circumstances the Fairphone 3 says “charging slowly”.
I gotta say the magnetic charger fits quite well with the bumper case. It barely sticks out, 1 perhaps 2 mm. I’d guess that is true for other magnetic cables as well!
To be fair, I feel less need for magnetic charger with USB-C as there is only 1 way the cable can fit. You could make a case for preferring such in case of tripping (like Magsafe).
Btw, the magnetic charger does NOT work well with the GPD Pocket 2. Often, it just quits charging, and the slow charging under load does not do much if anything. I’m now checking if that may happen with FP3 as well. With the GPD Pocket 2 I feel more desire to keep it connected whenever I can because the battery goes flat so quickly because Atom is inefficient; the reverse is true for Fairphone 3. Which simply leads to less stress and worrying about juice.
