Received very quick but I haven’t used or tested it out yet most good from AliExpress are good although I wouldn’t spend more than £30.00 due to previous experience when I received failed products and they just ignore you. So as they say Buyer beware

I was scared at first when I saw that the nameplate said 30V 5A even though I ordered a 60V 5A model. However, when I connected the device to the mains, it turned out to be a 60V 5A model. The information on the nameplate is incorrect.
R***l –
The power supply holds well to the given parameters. In the upper voltage range, a slight plus error. According to the seller’s description, it was supposed to be 30V/10A and actually has a range of 0-31V and 0-10.2A
