My Chuwi Hi10 Air came with a 5V, 2A adapter and a USB-A → USB-C cable. If the device needs 3A that would explain why I can’t keep it running indefinitely off the power supply (the battery just discharges a little less quickly). Indeed, when I boot the tablet under ChromeOS I get a warning that a low-power charger is being used (funny that MSWin does not show the same warning!)
I tried to use a 78W Samsung phone charger (with the original cable) that can deliver either 5V or 12V but didn’t notice any difference in charging behaviour.
Any suggestions for what replacement one might use?
How about this one: https://tinyurl.com/ydtekxac ?
because type-A’s absolute max. current is 1.25A.
That would apply to USB-A ports provided by hosts for more than just charging - when used in a PSU it could support any amperage, no?!
