Manufacturer description
The minidodoca 72W adjustable power supply is one AC/DC adapter for the pile of devices that lost their original chargers. It takes 100-240V AC input at 50/60Hz and outputs anywhere from 3V to 24V DC at up to 3A. That means a single unit can run a 5V Bluetooth speaker, a 12V LED strip or a 19V monitor. You set the voltage with a raised rotary knob, and the LED display shows the live output so you can check the number before you plug anything in. Turning the knob about halfway gets you to roughly 13-14V. An off position cuts the output without pulling the plug from the wall. The kit has 16…

Frequently Asked Questions
Can this power supply run a 12V LED strip or security camera?
Yes. Set the knob to 12V, check it on the LED display, and connect with the 5.5x2.5mm tip or the alligator-clip lead. The device must draw 3A or less.
Which connector tips come in the box?
16 pieces: Micro-USB, Type-C, a DC terminal connector, 6.5x4.4mm+pin, 6.3x3.0mm, 5.5x1.7mm, 5.5x3.0mm+pin, 4.8x1.7mm, 4.0x1.7mm, 3.5x1.35mm, 3.0x1.1mm, 2.5x0.7mm, a 5.5x2.5mm female-to-alligator-clip lead and three 5.5x2.5mm male connectors with cable.
Will it work on 220V or 240V outlets outside the US?
The input is rated 100-240V AC at 50/60Hz, so it handles both voltage ranges. Check the product listing for the wall-plug type before you use it abroad.
Can it power a laptop or monitor that needs 19V or 20V?
The output goes up to 24V at a maximum of 3A (72W total). It can work if your device needs 3A or less at that voltage and one of the 16 tips fits its jack. Check the requirements printed on the device's original adapter first.
What protection does it have if I set the voltage wrong or short the output?
It has automatic cut-offs for over-voltage, over-current, over-temperature and short circuits. The knob also has an off position, so you can cut the output and recheck the display before reconnecting.
