What this adapter powers

This 24 V 1 A AC-to-DC supply delivers up to 24 W for devices that draw less than 1 A. It suits routers, CCTV cameras, LED strip lights, speakers, fans and similar low-power 24 V equipment. It is not a charger and must not be used with battery-powered laptops or phones.

Capacity and headroom

The unit accepts 100–240 V input at 50/60 Hz and provides a regulated 24 V DC output rated at 1000 mA maximum. It comfortably runs loads from .2 A up to the full 1 A rating; exceeding that limit will cause overload. For Christmas light strings, total power should stay well below 24 W to maintain a safety margin.

Interchangeable tip and polarity

A single barrel plug combines 5.5 mm outer diameter with a 2.1–2.5 mm inner diameter, covering two common jack sizes. Polarity is centre positive, outer negative. The 1.4 m (4.6 ft) cord gives modest reach for desktop or wall-mounted devices.

Questions about this item

Will this 24 V 1 A adapter run safely on the 100 V–240 V mains supply in my older workshop?

Yes, the input range is 100 V–240 V at 50/60 Hz, so it works on standard mains worldwide without a voltage selector.

How can I confirm the adapter is delivering the correct 24 V DC output after I connect it?

Measure the barrel plug with a multimeter set to DC volts; you should read 24 V with the centre pin positive and the outer sleeve negative.

What comes in the box and do I need to buy a different plug for my 5.5 mm × 2.1 mm device?

The adapter includes a fixed 1.4 m (4.6 ft) cable ending in a 5.5 mm × 2.1–2.5 mm interchangeable barrel plug, so no extra plug is required for that size.
