144W Power Supply Adjustable DC 3V ~ 36V Variable Universal Switching AC/DC A...

Thank you for items like this. It really helps young and up coming electronic engineers like myself to start with basic tools and devices like this to power small projects and test creations. Really like it works perfect and I will be using it to power some of my future projects.

This device works well….the adjustment knob is quite sensitive to very small movements and it may change it easily so once you get it close to your target voltage, it’s hand off! I like the flexibility of the connectors and voltage range to adapt to my various device needs. A solid purchase for those with various changing voltage charging needs.

Eliminate batteries on so many electronic devices. A little hard to adjust to a certain voltage but I still prefer the adjustment knob over switches.

It arrived quickly and comes with lots of extras. I said “for what it is” above, because I think it’s a pretty cool little thing. My only problem was that it doesn’t hold a contact, dedicated and precise voltage like I need. It says it has all of these safety features but, I was using an very expensive piece of equipment and just couldn’t take a chance with the constant fluctuating of current so, I unfortunately had to return it and save for a larger and more expensive one, which I didn’t want to do. Otherwise, it was reasonable and nice and compact to work with.

Seems to do what I bought it to do , recharge older portable tool batteries. I've had the unit plugged in and charging it stays what I set the voltage at within a 10th of a volt. I've been using at around 15 volts and had no problems This comes with a bunch of adapters but I've only been using the clip leads which seem to be well made. Will update as needed but this seems to be a useful power supply

Gound the quality and functionality of this item to be subpar.

Voltage sag during a wind storm fried the power supply to my aquarium light. Bought this to replace it. The end it came setup with plugged right in, I just dialed it to 20v and the lights are on!

It's a flexible and easy-to-use DC power source. Has many adapter types, but it would be good to include 8mm as well (lots of power stations use 8mm charging ports). It had some issues with voltage droop when drawing high power (was set to 18V, but when charging a LiFePO4 power station at 50W it dropped down to 12V, fortunately not a problem for the power station). My biggest complaint is that, when I unplugged it while drawing current, it made a loud "POP" and died. Probably blew a fuse. The container is sealed so you can't fix it unless you're a technician.

Works perfectly, ideal in a small work/hobby shop.

Can choose any value between 3v-24v and works well.

Exactly what I needed Fast delivery Working perfectly

Easy to use, stable supply voltage, versatile adapter plugs. Everything you need is supplied including a variety of barrel plugs and alligator clips. Highly recommended.

Very versatile, husband loves it.
