Merchant’s special statement: Please note when customers place an order: this schoolbag with a USB data cable needs to prepare your own power bank, and then connect one end of the USB data cable to your own power bank and the other end to your own mobile phone charging cable to complete the charging. I wish you all a happy shopping
