I have a couple of questions about charging. What will happen if I connect the charger to the second USB port, not the dedicated one? Will it be destroyed? Will it be charged if I connect a 5V charger? What happens when I plug the USB dongle into the charging socket?

If you plug the original Chuwi 20v charger into the second USB-C port, nothing will happen. The laptop wonât be damaged in any way, it just wonât charge.
If you connect any PD charger to the first USB-C port, nothing will happen. Only the original Chuwi 20v charger will charge the device on the first port.
The second USB-C port supports USB PD (âPower Deliveryâ) for charging. However, it is only compatible with 20v power, so your PD charger typically needs to have a 45w output. The laptop will not charge on any other voltage - not 5v, not 9v, not 15v. It must be 20v PD to work on the second USB-C port.
Both USB-C ports will accept data connections, so you can connect regular USB devices (like memory sticks, hard disks, network cards etc) on both of the USB-C ports and they will work.
Video output is possible, but only over the second USB-C port. You cannot get native video output over the first USB-C port.

thank you very much for the clarification. thatâs what I meant
Iâm a little surprised when I checked my charger. this is A241 model with 12V 24W only. and this is the original charger. however it loads, but problemy slow. in the description there is that it supports 40W, so I can probably give a stronger charger?

From my testing the Minibook X will not charge at anything less than 20v PD. You might find it shows âplugged inâ and maybe even shows âchargingâ for a minute, but it will never actually recharge the battery.
As for actual recharging, the circuitry caps out at 20w. However, if youâre using the laptop at the same time, you might find 30w+ power draw from the adapter while it charges the battery and powers the hardware. Canât say for certain on that one though, havenât tested it.

Yes, thatâs for the proprietary charging port.
There are two USB-C ports on the device. The first one has data and 12v charging only. The second one is âfullâ with PD support.

Hi, your post is helpfull
I send back both Ugreen and Baseus 65W charger that i only test on 1st USB-C port
Before finding this thread, I didânt imagine to plug them on the 2nd USB-C port that donât have any lable
Hi, when you are writing that,
do we must understand 45W as a minimum ?
and can we use more powerfull PD charger such 65W ?
It doesnât matter how many watts.
Watts, or current, are âdrawnâ or âconsumedâ by the device. They are not outputted.
The voltage is outputted, and as long as the PD charger has a 20v output, you will be fine.

I can confirm a few things 
- It does not charge from a 12V/1.5A USB-PD powerbank. It says âConnected, chargingâ or something like this, but the powerbank turns off after a while.
Really a bummer since it can clearly charge from 12V so whatâs up with that. These powerbanks are much more common and much cheaper than 20V ones. - The supplied charger only charges through 1 of the ports, and is not USB-PD. Also annoying since it wonât charge my phone (well it will, in 4 hours at 5v probably), so I have to carry a PD charger, but it uses up the âfully featuredâ USB port
- 65W Lenovo PD charger with 20V/3.25A charges fine
- 30W Blitzwolf PD charger with 20V/1.5A charges as well.
I ordered a 20V USB-PD charger so should be able to test it soon.

Sooo I got the new powerbank and I have to report that it doesnât use 20V charging with the Minibook X. Only 12V.
As you can see it charges the Thinkpad at 20V but Minibook only goes up to 12V. This is using a 100W Lenovo Thunderbolt cable or a cheap Blitzwolf USB-C cable. Iâve seen it go up to 2A so far.
So I donât know why it doesnât work with my other powerbank. Either thereâs a fault with my specific powerbank, or it tries pull 2A and if the powerbank canât deliver it, it gets disabled? In any case Iâd suggest you try different powerbanks before spending money on a big and expensive 30W one.

hello, maybe you can help, I have a freebook n100, and it does not charge through the power delivery, I have a basseus 100w, and a couple of other units, and it does not charge from any of them, and only the charging comes from the original unit, and in the first output, only the charging goes, does not even see the flash drive
