Can you recommend any fast wireless chargers for Watch 8 classic and fold 7, would be nice to have 2 in 1 and charge phone and watch at max power. I know phone can charge Max 15W and watch 10W but when I tried to searched on Amazon max what I found for the watch was 3Watts. Why they don't make 10w?

This is great in our master bathroom to charge up the watch, phone and even earbuds while we're getting cleaned up!

@The_Chief  At only 10watts how fast does it take to charge all 3 items at the same time

Wireless charging definitely takes longer than wired: so I guess it's a matter of how you use your devices. I wear my watch at night for the sleep tracking; the phone and earbuds will charge overnight without a problem.

Yeah, if you use a charger that supplies more wattage than recommended, it can cause overheating and potentially damage your phone. It's best to stick with the charger specifications provided by the manufacturer to avoid any issues.

Battery technology has incrementally improved, so it may take less wattage to do the same job as before.

Example - Using a 100w charger won't cause any issues with charging the phone since the phones are design to only pull the power it can use. If a phone can max charge at 25w and you use a 100w charger it will only use 25w.

Now using a low watt wireless or low quality wireless charger will cause excessive heat in the battery.

Agreed, for the most part, however, the possibility to cause damage is still there due to overheating.

I've used a 65w and 100w wired charger for years and my phone has never gotten hot since the phone is designed to only use the max wattage the phone can handle. The only time my phone gets hot is if I have to use a low wattage wireless charger.
