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

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.

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.

I picked this power supply up for a small electronics project and have been using it on and off for a while. It does what it’s supposed to do, and the voltage and current adjustments are straightforward with the encoder knob. The output enable button is also a nice safety feature when you’re setting things up.That said, I wasn’t particularly impressed. The overall build feels just average, and it doesn’t really stand out from other bench power supplies in this price range. The display is easy enough to read, but the controls don’t feel especially premium. The USB charging port is convenient to have, although I haven’t found myself using it much.It’s not a bad unit, and it has worked without any major issues so far. If you just need a basic adjustable power supply, it’ll get the job done. I was just expecting a little more based on the product description.

Work for 5 minutes then it stop and start smelling burnt plastic... Kinda sad because I would love to have one working.....

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