Manufacturer description

The MTYTOT 12V DC power supply converts a 100-240V AC, 50/60Hz wall outlet into a steady 12 volts at up to 1.5A (1500mA). It works as a replacement adapter for low-draw electronics. It ends in a 5.5mm x 2.5mm center-positive barrel plug on a 1.4m (about 55-inch) cord, long enough to reach from a floor outlet to a shelf or desk. Matched to the right gear, this adapter covers a lot of ground: 3528 and 5050 LED strips and string lights under 18W, CCTV security cameras, DVRs, routers, ADSL modems, network hubs and switches, and audio/video communication equipment. Because of the wide input…

SpecPicks Verdict

SpecPicks scored MTYTOT 12V DC Power Supply 1.5A Universal AC Adapter using a rating × review-volume × price-fit model applied to published specs and reviews across the accessories category. MTYTOT's accessories lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for accessories of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Will this 12V adapter work with my device?

Check your device's label for four things: it needs 12V DC, it draws 1.5A or less, it takes a 5.5mm x 2.5mm barrel plug, and its polarity is center positive. If all four match, the adapter is compatible.

Can I use it for a device that needs 12V 2A?

No. Output is limited to 1.5A (1500mA), and the manufacturer warns that devices needing 12V 2A, 2.5A or 3A will cause it to overheat. Choose an adapter rated at or above your device's current draw.

How long of an LED strip can this power supply run?

It is rated for 12V 3528 and 5050 LED strips and string lights under 18W. The manufacturer recommends staying under 80% of the 1.5A full load, so check your strip's watts per meter and keep the total within that budget.

Does it work on 220V or 230V outlets outside the US?

Yes. The input accepts 100-240V AC at 50/60Hz, so it covers both 110V and 230V mains. The plug style on the wall end may still need a travel plug adapter, so check the listing for the prong type.

How long is the power cord?

The cord is 1.4m, about 55 inches, ending in a 5.5mm outer diameter by 2.5mm inner diameter barrel plug with the center pin positive and the outer sleeve negative.
