🔌 YI MEI DA 48V 16A 800W Switching Power Supply with Driver Display – Ideal for CCTV, Computer Projects, 3D Printers, LED Strip Lights, Routers Review

If you need power then this is the one for you. it's not bad. The only downside to using a car audio amplifier this way is that the lights in the house are pretty dim.

If you use this item in your home and want insurance if it catches fire, this will not work. BUT, if you want me to live in a concrete box, the UL listing isn't important. Works as expected for LED installations, 5 stars.

The product name says "YI MEI DA Upgrade 48V 20A 1000W Switching Power Supply Power Adapter AC 110V/220V Driver Transformers SMPS for CCTV Radio Computer Project Led Strip Modules Light" for you to use it at 110 can or 220 volts, but as you can see on the label in the photos it only says 110 volts and there is no button on the back of the power supply to change the input voltage to 220 volts. So it's an error in the title and product images?

Used with a built in cable line with a power switch and from there to the car audio amplifier to power a pair of 500w subwoofers for a home theater system and it works great and also has a built in fuse for safety.

If you're going to use this thing in your house and want to get insurance if it lights up, then you can't. BUT if, like me, you live in a concrete box, the UL listing is irrelevant. Works as expected for LED installations, 5 stars.

If you need a power adapter, this is it. I had no problem powering a 1000w car audio amp with this power supply, it does get a bit warm but it's not a big deal. The only downside to using a car audio amplifier this way is that the lights in the house are pretty dim.
