12V 4A Power Supply - COOLM AC 100-240V 50/60Hz to DC 12 Volt 4 amp 4Amp 48W Power Converter Charger 12V4A + 5.5x2.1mm DC Female Jack Socket for 12V LED Strip Lights CCTV Camera

I literally opened the package and walked outside and installed this replacement transformer. The old one has a broken lead up within the waterproof harness. For the sake of convenience I simply cut and stripped the leafs from the lights and slipped into the provided adapter and then plugged in thenew transformer to an extension cord. Important to note that this replacement unit is NOT rated for waterproof or outside conditions. I am using it in a sheltered area and will take additional steps as well as actually taping the bare wire leads. This is actually just a test installation to verify that it would operate correctly for my application. I've included a picture of the original transformer output specifications, this seems a little bit brighter. Overall functional, value for money and delivered overnight.

Works great for running a couple 12v things in my 3D printer enclosure. My only compliant is that the screws to attach wires are very small and recessed. I have to find my tiniest screwdriver for them. It would be nice if they were more accessible.

My sons factory adapter for his chromebook burnt out, This was a great purchase to replace the adapter.

I purchased this as a replacement power adapter for a Kebonnixs 12 egg incubator. I works perfectly.

As advertised.

I ordered this for a fiber optic tree (12v 4a). When I received the power supply, I tried it and found the tree lit but did not turn. In my experience, all power supplies have been AC to DC. After re-examining the old power supply, I found it to be AC to AC. I contacted COOLM to see if they had the correct power supply. They said they didn't have one, but had actually searched to find one for me. When they could not locate one, they gave me a full refund. COOLM went above and beyond to resolve my problem. Thanks COOLM.

Works, stays cool. Decent length cord.

I needed to add an LED light bar to a truck we are using on a job site. I found a great light bar that would easily plug into a cigarette lighter plug in the truck. WTF? New trucks have tons of USB ports, even an AC receptacle, but NO lighter plug. I did quite a bit of research and found this AC adapter that could be powered by the truck's inverter and provide enough wattage to power the light. But what really sold me was the "pig tail" plug. This allowed me to simply remove the cig plug from the light bar and connect the leads to the pig tail plug. Easy peasy.
