Help me please about AC200PL

Good day, tell me how to find out the manufacturing date of the charging station (AC200PL) and how to register it with the manufacturer, thanks in advance, and another question, are there instructions for properly disassembling the station, it’s just that when you tilt it, something rolls around inside, either plastic or a washer, the station works on its own, but this foreign object needs to be removed.

@OleksiiUA
I know from your description that your AC200PL has an internal rattle, a condition that requires contacting your dealer for a replacement. May I ask where you purchased it?
Please provide your AC200PL SN and the sticker barcode on the bottom of the machine and send to the seller for the replacement.

Yes, unfortunately, something is rolling there, but the Station works, SN: AC200PL2425000021477, I bought it in Ukraine, but we do not have an official representative

@OleksiiUA For orders not placed through the official BLUETTI online store, you may need to contact your seller to negotiate a return or exchange.
