i bought a yocan hit via AliExpress the device came with a pre-charged battery and works great. but when connected to usb c the battery charger does not charge. i have tried different cables and AC chargers as well as the power bank but simple charging does not work. Can you give me advice?

Answer:
We don't have a official store on AliExpress, please check the authentic code on www.yocan.com/#support

Any information display when you charge the Yocan HIT?
If possible, please make a short video and send it to us.
