Where can i find the seariam number on the EB3A ?
Turn on the EB3A power and connect to the APP via Bluetooth, it will show “EB3AXXXXXXXX” (13 Arabic numbers), which is the serial number.
@bluetti_m3ckb1222gmailcom as @BLUETTI mentioned, you can find it within the app, or you can also look at the bottom of the unit, and it should display the S/N right below the QR code.
