Thanks for your feedback.
When the battery is fully charged, the battery logo is white, and the lightning label will not be displayed when the USB cable is inserted.
If the battery is dead, the battery symbol is yellow, and insert the USB cable will have a lightning symbol. (Please check the picture below)
If the wallet you received cannot be charged, please try to charge it for a long time (such as charging for 24 hours) and then check if it can be fully charged.
If it still does not work, we recommended you to replace a good USB cable and try charging again. If you still have questions, feel free to contact us.
Thanks for your cooperation.
