1. Test steps:
①, the assembled semi-finished product, use 20W/5R resistance load to discharge the power (1A load).
②. Charge the discharged semi-finished product with a 5V/1A charger, and observe whether the display status is consistent with the instruction. OK.
③. Discharge the charged semi-finished product with a 20W/5R resistive load, and observe whether the display status is consistent with the manual. OK, the test is completed.
④. Charge the discharged semi-finished product with a 5V/1A charger, stop charging at 70%, and then assemble the finished product.
⑤ After assembling the finished product, use a 20W/5R resistive load and a 5V/1A charger to do charge and discharge tests to prevent damage during assembly.
