I am thinking about buying one of those USB power meters, which I have seen people here in the forum use.
What should I look for if I want the most versatile model ? Any specific model recommendations ?
I see some are with PD and I also find its nice to have many connector options USB-A/USB-C/micro USB.
And some are with app connectivity by Bluetooth, sounds also like better display and perhaps more features ?
And can they stop charging after limited time or when battery is 90% full or after set amount of mA etc ?
Summarizing how many mA was charged, is that standard ?
