I too have one, albeit not the same as Beefheart’s. Mine has a UK style plug with fuse, Samsung battery, and confirmation from the seller that it has passed testing, together with a SGS test cert from SGS China.
I suppose technically all those things could be faked too…..
Would trading standards be able to advise if they’ve tested from this seller?
Would SGS confirm that they have tested the boards on behalf of the supplier (the Cert has a reference number and name)
I’d suggest opening it up and looking at the battery.
Does yours make sparkles?
Not sure Trading Standards can do anything if the seller is from China.
