Manufacturer description

The SHNITPWR 12V 10A 120W DC power supply adapter turns 100-240V AC wall power into a steady 12V DC output. It is built for LED strips, security cameras and other 12V gear that needs more current than a typical wall adapter can supply. It delivers up to 10A, so it can drive long runs of 5050 or 3528 LED strip, a multi-camera CCTV system, or a 3D printer from one brick. Your device takes only the current it needs, whether that is 500mA or 7A. The output plug is a 5.5x2.5mm barrel, center-positive, and it also fits 5.5x2.1mm jacks. That covers most routers, hubs, LCD monitors, webcams and LED…

Frequently Asked Questions

Will this 12V 10A adapter fit a 5.5x2.1mm DC jack?

Yes. The tip is 5.5mm x 2.5mm, and SHNITPWR states it is compatible with 5.5mm x 2.1mm jacks. The center pin is positive (+) and the outer sleeve is negative (-).

How many feet of 12V LED strip can this power supply run?

It depends on your strip's watts per foot. The adapter is rated for 120W, and the maker recommends staying under 80%, about 96W. Add up your strip's rated wattage and keep the total below that figure.

Can I use a 10A power supply on a device that only needs 2A?

Yes. It supplies a constant 12V, and the device draws only the current it needs, such as 500mA, 2.5A or 7A. The 10A rating is the maximum it can deliver, not what it forces into the device.

Can I charge my laptop with this 12V adapter?

No. SHNITPWR states this is an AC to DC power adapter, not a charger. It should not be used to charge battery-powered devices such as laptops, because doing so may damage them.

Does it work on 220V or 240V outlets outside the US?

The input is rated for 100-240V AC at 50/60Hz, so it covers both North American and most international mains voltages. You may need a plug adapter for the wall socket shape.
