Recharger of another device

[salvomic]

hi,
if I'm not wrong, the charger of Gemini is 5V/2A and also that of Huawei MediaPad M5 (8") is 5V/2A, so I reckon I could interchange them as well (beside of the fact that one is black and the other is white...). Isn't it?

Your media pad is being powered by a HiSilicon SoC and not by a Mediatek, thus, most probably it won't work, or at least fast charging won' t work due to the lack of PumpExpress.

oh, thank you, I din't know it, I thought the only important thing would have been to have the same voltage and amps...

here there are: White Huawei, Black Gemini Image.

I think the Gemini will charge at a "standard" rate with most 2A chargers - I charge mine with a fairly generic dual port USB charger 5V@2A and 5V@1.2A  - it works fine.  

With the "right" charger it will charge faster - Gemini and charger negotiate over the USB data lines and use a  higher voltage - one of the limitations on the charing rate is the  current on the USB connector - most are only rated to 2A.   so increasing the voltage = more power = faster charging.

This is what phrases like "pump express" mean below,  there's another thread on this here:

@rubus-3.142: thank you!
I'm reading that thread.

my other phone can do fast charging, but I prefer to charge slowly because, perhaps wrongly, believe slow charging is better for battery ageing - partly due to increased risk of dendrites on the electrodes, partly from the raised temperature.
I do fast charge when I need my phone in a hurry.
