So far.

So far I've only seen 500mA. mAH is milliAmpHours. A capital M would mean Million.

There have been long fights about 0.5 vs higher charge rates but from my electronic design background, 500 mA charging is just fine. Should result in less heat and longer battery life. (Life, not time!)

Note: Corrected post with edit. For this conversation we are talking current and not charge capacity.

Ok so maximum mah in a new smart TV is 500mah

In reply to: So far.

Good to know it’s only 500mah in new smart tvs. It’s ok for me to charge slower. I dont want to charge it too fast, and to have ps4 on to charge is not a good solution.

The caveat is of course "unless specified otherwise." Since USB 1.0 the maximum current was set to 500 mA that is almost without fail what you find on USB ports unless documented otherwise.

I see I made a mistake about add the Hours to that. AmpHours is capacity and here we are talking current only.

I'll fix that with an edit.

What about usb3?

In reply to: Caveat.

Could the TV have usb3? I have one USB port on my PC. Do USB 3 charge more mah pr hour or is it just more speed when transfering files on PC? Happy

I covered that.

"unless specified otherwise." Since TVs don't need more than say 25 megabits per second to play UHD content, the TV makers are unlikely to fit more than USB 2.0 ports. USB 1.0 from memory was only 11 megabit and my bet is there is no cost involved moving from 1.0 to 2.x.

If you see the usual BLUE USB 3.0 port, "unless specified otherwise" it should deliver 0.9A.
