Any thoughts about Qi wireless charging? This battery is so small you wouldn't need a very big coil to supply its max input current.
My mobile world has gone completely wireless. I no longer use or want USB-C or Micro-USB or 3.5mm or anything else. In fact, I'd be happy if my phone had no holes at all. It would be nice to drop IEMs on a charging puck too, rather than fiddle with the port protector. (That little bit of rubber always tears soon anyway.)
Not there yet. Coil is too big if we want to keep similar size and cost is an issue. We have been looking into this for a while though so hopefully can bring you something eventually.
