## Description

Specification: Name: Adjustable Power Adapter Color:Main Black Input: AC 100V~240V 50/60Hz Output Voltage: DC 3V~24V Adjustable Output Current: Max 3A Output Wattage:Max 72W Output DC connector:5.5mm x 2.5mm (inside"+", outside"-") 14 Tips Size: 6.5x4.4mm+Pin, 5.5x2.1mm, 5.5x3.0mm+Pin, 5.0x2.1mm, 6.3x3.0mm, 5.5x1.7mm, 4.8x1.7mm, 4.0x1.7mm, 3.5x1.35mm, 3.0x1.0mm, 2.5x0.7mm, Micro-USB, Type-C and DC terminal connector. Reverse polarity converter: 5.5mm x 2.1mm Power cable length: 6.9ft / 210cm Safety Compliance: FCC / CE Working Temperature: -20~50℃ Ambient Humidity: 5~95% Non-Condensation Weight: 1.1 lb / 500g Fetures: -High quality components. -Application:Can be used for DC moto speed control,light dimmer,laptop,printer and so on. -Noted: 1.The adjust power within the range 3V~24V(±5V) 2.The power cord between power brick and DC plug will lead to 0.4V~0.6V voltage drop, so we designed the screen displayed voltage was 3.5V~24.5V. Only in this way can your device really get 3V~24V voltage. This is the reason why we advertise the power supply's voltage range is 3V~24V, not 3.5V~24.5V. Package included: 1 x 120W Universal Power Supply Adapter 1 x Reverse polarity converter cable 14 x DC Tip

Review: Good quality - This is such a useful power supply. From 3v-24v 3 amp 72watt supply in increments of 0.1v, with clear led display. Works well, stable, runs cool, has screw hole fitting for wall/floor mounting. I am using some of these in my recording studio on old/fragile/expensive equipment. Had no problems. I'm sure they would be equally good on railway layouts etc. Be aware it takes a careful hand on the 'knob'.. to set the exact voltage, but once it's done. it's done.
Review: Working great for a few months of intermittent use - 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.

### ⭐⭐⭐⭐ Flexible PSU but not really suitable on the Road
*by M***. on 27 June 2022*

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.
