Can you buy a replacement air case?

Hi Friend,

Thanks for choosing EarFun. Sorry for the inconvenience caused.

Could you please send us your order number to check first?

Under this circumstance for trouble-shooting, we would suggest you use our original USB-C cable and try switching different cables also even sockets to exclude the reasons of external factors. 

If you have a wireless charger, could you please try charging the case for 3.5 hours via it? We kindly suggest you try to adjust the place and put the case in the center of the charger.

If none of this works, it would be helpful for us if you could kindly shoot us a video that captures the light changes of the case using the same cable to charge the case and another device and email our customer service team via service@myearfun.com or submit the warranty ticket on our official website: https://www.myearfun.com/process-warranty. EarFun provides an 18-month warranty for every product. Your satisfaction is always greatly important to us.

Sincerely,

EarFun Customer Service Team
