Longwei K3010D 4-Digit LED Display DC Power Supply Variable, 0-30 V / 0-10 A, 4-Digital LED Display

Works fine and erfect for general use.

It does exactly as described. It saved me from buying 2 new flymo batteries (saving £140+), The charger was a smart one and as they dropped below a certain amount would not charge. 30-60 seconds gave the batteries the charge it needed and was recognised by the supplied smart charger. (please don't copy me, but it worked)

Well, initially I was going to leave a negative, 1 star review but... Eventually I persevered and stuck with the unit, fiddling about with the controls as best as I could figure out (not really worth referring to the manual, it's almost useless). The process was a bit hit-and-miss BUT eventually had the unit working as supposed, powering a surplus PC fan. I will attempt to explain at the end. The item was well packaged, compact and a nice looking unit. Process: While unit is OFF and +/- leads attached, turn VOLTAGE to MAX and CURRENT to MIN. Then create a short with the leads (nothing should happen). Turn unit ON - Turn CURRENT to MAX - adjust Voltage to required setting. Current will automatically adjust This is the process I used. Prior to this the voltage dial wouldn't set and fluctuated wildly from 0-20 V (with no between adjustment) leading me to initially think the unit was faulty.

Had this a while now and seems OK

Great quality product for the price

Used this to power the wiring on a 1930s tram while attempting to diagnose how it was all wired. Very successful, as it shuts down successfully when there is a short.

Very good

Good kit, worked fine. Only disappointment is quality of the terminal knobs that feel cheap and nasty.
