Bought an Anker power bank at the start of the year and recently it died.... Wouldn't take / hold a charge ....
Sent a email to Anker customer service attached a pdf of my receipt a photo of the serial number and attached a 20 second video of the fault....
Emailed me back to try a BMS reset which didn't work replied to that
Next email wanting address within 4 days a New power bank appears in the post .....
Can't complain at all
