Le port USB C (théoriquement Full) peut-il être utilisé pour charger la batterie?
Si oui quelles sont les caractéristique électrique (u,i…).
merci
Hi.
Have you asked CHUWI support (or after-sale) about this matter?
Anyway,
- USB type-C port must support PD 3.0 to charge PC battery.
- If all equipment is compliant with USB specifications, they don’t break by any connections. But there are some practices which aren’t compliant.
If wrong, please correct…
EDIT:
For a long time I am wondering why CHUWI doesn’t clearly notify users what type USB hub is applicable for charging CHUWI PCs.
Maximum current limit (not rated current!) specified in USB spec is 1.25A/pin, so if PC needs around 20W for charging, 5V output is not enough, 9V or 12V is required. This means that common 5V USB charging hub cannot be applicable for most over-20W Laptop PCs’ batteries, even if PCs’ USB type-C ports are compliant with PD3.0. In this case use USB3.0 + PD3.0 hubs with 9V/12V supply capability. Of course, USB 3.0 cable must be able to flow more than 3A/9V(or2A/12V)
(FYI: MiniBook’s battery’s input is 7.6V(rated voltage). So MiniBook wants 9V from USB. In fact we cannot charge MiniBook battery with 5V only USB hub. There may be other models like this).
MORE SPECIFICALLY
CHUWI KNOWS THE EXACT VALUES OF VOLTAGE/AMPERE USED IN POWER CONFIGURATION OF USB PD3.0. I CANNOT UNDERSTAND WHY CHUWI DOES NOT MAKE THEM OPEN TO THE PUBLIC.
