"The M10P uses Huawei's proprietary charger"
I have a 9 and I love it, the Standard USB C 2 amp charger gets it charged up pretty damned .
But anything that mentions "proprietary" quickly becomes a PITA... It usually involves having to buy at least 2..... One for home you get that included, but then another for work and another for travel.. AAaaagggghhhh.
If it is not standard, forget it. I already have bags full of old proprietary chargers and I refuse to return to anything non standard.....( Shame that laptop manufacturer never understood that either)
