Universal 24W Multi-Voltage Adapter

This 24W regulated switching supply accepts 100-240V AC input and delivers seven selectable DC voltages from 3V to 12V at up to 2A. Eight interchangeable tips cover barrel sizes from 5.5×2.1mm down to 2.5×0.7mm plus a Micro-USB and LED terminal connector. Built-in over-voltage, over-current, short-circuit and over-temperature protection keeps connected gear safe.

Suits low-power household electronics

Hobbyists powering LED strips, routers, speakers, cameras, keyboards, scales or USB hubs will appreciate the single-brick convenience. Devices that need more than 24W, a voltage above 12V, a proprietary connector not in the kit, or a permanently fixed cable should look at a dedicated supply.

Seven voltages and eight tips decide fit

The unit only works when the device voltage matches one of the seven fixed steps and the polarity plug fits one of the eight supplied tips. Measure the original adapter’s output and barrel dimensions before ordering to confirm compatibility.

Questions about this item

What does the 24 W rating mean when the adapter is powering a device?

The 24 W rating is the maximum continuous power the unit can deliver, reached at 12 V and 2 A; at lower voltages the wattage drops proportionally.

What AC input range does the adapter accept and what does that cap in practice?

It accepts 100 V to 240 V AC, so it works on mains supplies worldwide without a voltage converter.

Which plug sizes are included and what do they physically need to fit?

Eight tips are supplied: 5.5 × 2.1 mm, 4.8 × 1.7 mm, 4.0 × 1.7 mm, 3.5 × 1.35 mm, 3.0 × 1.1 mm, 2.5 × 0.7 mm, a Micro-USB connector and an LED terminal connector.
