So there is an inherent vulnerability with USB PD.
With a non-PD “traditional” charger there is a fixed voltage, typically 5V and a maximum Ampage, say 1A, 2A, 2.4A, 3A. The voltage can never increase, and the device being charged has a resistance to taking more than it can handle.
PD however can do 9V… 15V…20V. So suppose the device can only handle 5V, if it were to be given 20V, it the distance between the wires, insulated to handle 5V, can be fried if they experienced 20V.
So with PD you have to be sure that both sides of the PD are perfect.
Now as the Atom 1 has a maximum 20V, so long as you connect it to a device which can handle 20V input, they can’t be fried, you might suffer over-heating, say, of the Atom, or of the cable, but you’d not fry the device. You may find charging does not work as they negotiate to a useless low voltage.
Take say my Huawei mediapad tablet, it can only handle 9V, so if I connected a charger capable of >9V, I risk it being fried. But say my laptop, which is a 20V input, I can not fry it, but I also may simply not work.
Given Anker is a business, exchanging products for money, you can handle this probably safely in 2 ways:
- Ask Anker if your device will work. If they say it does, and it doesn’t then you have some argument in your defence.
- Ensure the transmitting voltage of the charger is not more than the maximum receiving voltage of the device, and if they don’t get along then use the 30 day Anker no-quibble return option.
What I am doing is still sitting out of this PD problem for a couple of years longer than I ever thought I’d need to, a new 8.4" tablet and it will only see its supplied charger, or Anker 5V 2A.
