Title: Does the GPD XD+ support some form of quick charge?
Post by: foxsevent on September 15, 2019, 09:24:37 pm
For a while now I've noticed that when charging my XD with a charger that supports quick charge it does actually charge faster, thou this does make the touch screen behave oddly when it is touched.
But recently I bought a power bank with a voltage and amperage meter, s and I've noticed that if I connect the XD+ to it's quick charge port it draws 9 volts at 1.5 amps, on a regular USB port it obviously draws 5 volts but at 0.7 amps.

Should I be worried about using the quick charge port? I do know that over voltage can shorten the lifespan of the battery.

 Did a little test, from 0% to 50% took 1h 5min at 9v 1.5amp
Once I drain the battery again I'll test it at 5v 2amp, but there's an interesting note after 60% charge the charging speed drops hugely on 9v to below 0.5amp and 5v below 1amp.
So overall 0% to 100% time could be similar.
1h with 5v 2amp  gets you to 35%, so 9v 1.5amp is definitely faster but only up to 60%

I believe most fast charging tech stops "fast" charging at about 75-80 %.

This is interesting info. Thanks.

I think XD and XD+ both not support quick charge.

XD does not support quick charge and will burn out the mobo if you try.

XD+ doesn't officially support quickcharge but will NOT burn out if you use a quick charger.

The weird thing is, i connected to the uart ports on an xd+ and I see messages related to pump express ( the mtk fast charging tech ). So maybe it could support it with a firmware upgrade maybe? Technically the MTK in the xd+ is supposed to support PumpExpress 2.0
