Works exactly as needed for little money, multiple connectors prove really useful with adjustable voltage making it an ideal piece of kit if you lose a power supply

I ordered two of these with my own money. Not affiliated with the manufacturer in any way.worked great for a tv for a short time (I accidentally smashed the screen when I disassembled the tv to swap out some lights inside it) and then now I use these for powering up 5 meter strips of 24v LED strips.I can confirm it can dim the light all the way from zero to maximum brightness using the voltage knob. In a few specific voltages there's a little flicker in the lights but if you turn the knob a few tenths of a volt it will go back to normal.No PMW flicker so these should be good for video lighting. Though I didn't test high frame rates.No noticable noise issues.Great screen that appears to be actually measuring the voltage.There's a strange burst of power that comes out after it is turned off. With the light it makes the light shine up again for a split second. Not sure what's up with that but it's not a major issue for me. Both units do this.Overall very happy. Versatile and appears to be very well made for the price.

This PSU is very versatile with multiple power connectors and variable outpt voltage at up to a quoted 120W capacity.I bought it to replace a dead 19V 90W PSU for an older laptop. When powering this it does get quite warm but probably no hotter than many other laptop supplies I have used. However what it would be like running flat out (30% higher load) I don't know but probably hotter than I would feel comfortable with.What is not clear from the specification is that the output voltage control is continuously variable. This means that unless one is careful with the siting of the unit the knob could be knocked and the voltage changed with disastrous consequenses. As such I don't think it ideal as an "on the move" device. In fact the case even has mounting holes at each end so it can be fixed to a bench or something. Coupled with the relatively short and captive mains supply lead it feels more suitable as a test bench supply cabable of powering almost anything and everything. This makes it a very useful device if that is what you are after.I found the built in voltage indicator consistently slightly (0.4V) optimisitic compared with the voltage on the output connector, even under no load and the discrepancy didn't seem load dependant. I did notice, however, the voltage sagging with use by up to 1.5V for a nominal 19V output. This was not directly load dependant but more thermal drift. As the unit got hot under load the voltage sagged. Remove the load and the voltage only returned to the original value as the unit cooled down, not immediately the load was removed.To be fair though I have no idea of the stabilty of most laptop PSU's as they are under load/heat up since they don't atually include any display. The laptop I used it with didn't seem fazed by this slight drop in use so I was loathe to adjust it in case I forgot to reduce it again under light load and overvoltaged the computer.For my use case its almost ideal, only the slight displayed voltage error and thermal drift losing it its final star. The flexibility it offers though for testing devices or powering them in an emergency is hard to beat.

I needed a power supply for my nas drive and thus was a 3rd of thd price of all the other units I looked at so I thought I'd take a punt. Turns out to be an excellent product. I especially like the dial for setting the voltage rather than several presets.

Good adjustable power adaptor that was needed for my LED lights. Thanks.

After several attempts to buy tips for my laptop, these actually work! Worth its weight in gold!

Great product I needed s 15 volt charger for a vehicle starter power bank, as power bank was totally discharged the charger overloaded at 15 volt initial setting but found if I started at 8 volts and adjusted up from that it was fine, the charger is middle pole positive which is fine for most things but I did some testing on the cable that came with it which stated that it would reverse polarity I did a voltage test and a continuity test which confirmed it made no difference please test the one that came with yours just in case it was just mine, but as I said most items are center positive so no biggie. when I get time I will cut the cable and wire it to suit

Good piece of kit with all the connectors and you will need not buy anything else etc. ideal for hobbyists and engineers.
