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: Easy - I’m not technical, but I used it to revive my laptop. Great thing, easy to use.

### ⭐⭐⭐⭐ Almost perfect
*by J***T on 19 December 2023*

Extremely versatile but for one exception, the leads need to be a bit longer. Easy to adjust the output and loads of 'plug' options to connect to devices. Highly recommended.
