Review on 💡 Kungber DC Power Supply Variable: 30V 10A Adjustable Bench Linear Power with LED Display & USB Output, Coarse and Fine Adjustments by Phil Prater

Update: I have expired my Revain 30 day return period and the seller is not responding. Do not buy. Original review: I ordered these at the end of January 2021. I used it to charge several LiFePO4 batteries. So it was used at either 3.6V or 28V, with the current limited to 9A in both cases. Today I started it at 28V and let it work. When I came back the device was off but toggling the power button did nothing. I opened the case and found that the thermistor (it appears to be labeled RT1) had literally burned out. There was a pile of ash at the bottom of the case, just below the two now exposed resistor leads. 28V @ 9A is definitely below the spec for this PSU (30V @ 10A) so this is unacceptable. I would not recommend this power supply.
