DC power supply (0-60V,0-5A) adjustable, switching power supply, mini high precision 4-digit display with USB fast charging interface, variable lab bench power supplies, output on/off/encoder knob

I like to diagnose and fix electrical items for friends and occasionally I get an e-bike or scooter to look at that never get dropped off with the chargers and often almost flat batteries. I needed a bench power supply that would allow me to supply voltage of varying levels to the different bms’s of the 36v or 48v e-vehicle batteries, allowing me to power them like the original wall plug was being used, and this supply is currently charging a flat e-scooter battery that was left with no charger but now I don’t have to deal with that issue anymore unless I service anything over 60v. I only gave four stars as 5 for me is always reserved and the only issue I can fault with this psu is the alligator clips that come with it and how damn slippery they are to try and squeeze and get open without feeling like your holding a wriggling slippery thing that keeps popping out of your fingers. And for those that don’t like the beeps as they’re too loud and seem to think that opening the machine to remove buzzer or cover over it is the only solution…, you need to read the manual page 11, it lists the basic device menu options and one of them is to turn the annoying beeps of with no need to open up the psu, people need to learn to start reading instruction manuals that come with things as it often helps.

Works as advertised, I have many lithium batteries for yard equipment that i had let drain fully down and sit for a few years. $60 plus to replace each batteries that would not charge because of fault protection, took mins of hitting them with this charger for a few mins and they are now back to charging on their regular chargers now. This paid for itself with just repairing one of the ego batteries. Handy for many things.

Easy to configure to a variety of small projects. Great for powering and testing electrical components. I use mine to test IoT devices.

Works just as described. I've used it to charge weed Wacker battery that wouldn't charge with the original charger anymore

So far works great top balancing my LiFePO4 48v batteries.
