Can I use the USB-C port on the new Corebook X to charge it?
Yes, the correct power supply is required. 20V, 15V and 12V with> 2A it should support. As a rule, it is the output from 65 watts. The USB-C cable must of course also support the service.
I have a 100W GaN USB-C charger. It is so slow with the Corebook X.
A friends 65W did not work well either.
Does the USB-C cable also have the clearance for> 3 amps? It only works if the USB-C cable has the corresponding chip in the connector. Otherwise it stays at 1 ampere, which at 12 volts = 12 watts.
Yes 
The cable can deliver 5A/20V (100W) and it works well with other laptops. Does USB-C charging work well for you?
Yes, it works for me. However, you should be aware that the UBookX does not support 65W.
When charging via USB-C, the UbookX is roughly in the same range as it charges with the normal charger. According to my power bank, the UBookX draws between 12V 0.8A (battery full) and 12V 1.8A. So it is in the range of 10W - 22W. My power bank supports 65W with up to 20V 3.25A.
So you have the UBookX (tablet)? And not the Corebook X (laptop) this thread is about.
Yes, I use a Ubook X. The CoreBook X, however, has the same full-featured USB-C. Unfortunately, the indication PD2.0 Fast Charge doesn’t really say anything about the speed. But only that it can be charged faster with a USB-C PD power supply than with 5V 1A.
The USB-PD 2.0 uses so-called profiles. These are …
1.) 5V 2A, 12V and 20V unsupported (max. 10 Watt)
2.) 5V 2A, 12V 1,5A , 20V unsupported (max 18 Watt)
3.) 5V 2A, 12V 3A, 20V unsupported (max. 36 Watt)
4:) 5V 2A, 12V and 20V 3A (max. 60 Watt)
5.) 5V 2A, 12V and 20V 5A (max. 100 Watt)
They themselves determine which profiles the manufacturers use here. But profile 1 alone can be called Fast Charge.
To the best of my knowledge, Chuwi uses profile 3 on USB-C.
Chuwi states this as well. You write that when charging via USB-C, the battery will be charged to 60% in one hour.
The battery has 46.2W. 60% is 27.72W. Profile 3 has 12V with 3A so 35 watts. Taking into account the charging losses …
The USB-PD 3 standard is required for 65 watts of charging power, since voltage and current are only dynamically adjusted here. Because only with this standard can 20V and 3.25A be charged. With USB PD 2.0 you can only use the fixed profiles.
Bonjour. J’ai un corebook x et ça fait un moment que je cherche comment changer par l’usb c. Car la batterie s’épuise vite quand je fais de la musique. Car j’utilise beaucoup de logiciel simultanément. Je voulais pouvoir profiter de mon laptop en extérieur avec une meilleure autonomie. C’est pour cela que je voulait charger par usb c avec une batterie portable.
J’ai commandé un premier chargeur de 20 w mais ça n’a pas fonctionné. Là j’attends un nouveau chargeur de 60 w PD 3.0. d’après ce que j’ai pu lire, ça devrait fonctionner. J’ai un câble usb c vers USB c qui est adapté au chargement. Je devrais être fixé dans la semaine. Je croise les doigts. C’est dommage d’avoir un ordinateur portable et de n’en profiter que branché à une prise électrique. Je voudrais pouvoir profiter des beaux jours et faire de la musique en extérieur. Merci pour vos indications. Ça m’a bien aidé et aussi rassuré. Car à force de chercher je commencais à douter et avoir peur de brancher une batterie inapproprié ou trop puissante et de cramer mon port usb ou pire endommagé mon ordinateur.
Je continu de suivre cette rubrique pour en savoir davantage. Si quelqu’un à des conseils à me donner, je suis preneur.
Merci encore.
Hello
I use a Blitzwolf 65W and I-m able to charge it using USB-C. Anything lower than 65W will most probably not charge.
Regards
ML
not working, i am trying all these but unable to charge
Do you have USB PD charging activated at BIOS level? Sometimes this comes deactivated.
