Qi2 is nice, but this genius trick makes it cooler by adding fans to the chargers
Heat dissipation is a simple trick, but it's essential for wireless chargers.

Here at Android Authority, we’ve been chomping at the bits, waiting for Qi2 to come to our Android phones. Faster wireless charging and magnets (or not, as it turns out that companies can implement Qi2 without them) would be cool to have in everyday life, but I don’t know if I’d ever rely on just wireless charging all the time. It’s just slower and inefficient, and it generates a decent amount of heat, which causes most phones to throttle the power they draw from wireless pads to avoid going up in flames.
The solution is, though, absurdly simple, and I’m surprised I haven’t seen it before already. Fans — and built-in cooling systems. That’s it. You don’t need more. Just dissipate some of the heat in the opposite direction of the phone, and your wireless charger should, on paper, remain cool and efficient enough that phones keep drawing power at a good rate from it, thus charging faster.
