Mean Well LRS-50-12 Switching Power Supply, Single Output, 12V, 4.2A, 50.4W, 3.9" L x 3.23" W x 1.18" H

Bought this to replace the power supply in my Peltier-based desktop mini-fridge. It was practically a drop-in replacement and works very well - more efficient than the original PSU.

Worked perfectly much more reliable

Works great!

Strong adjustable power supply. Does not heat up too hot to handle. I use it to power a silicone heating pad, and have the hot line coming from a temperature controller. No power issues after several long days off use.

Used this to repair a Frgidaire 6 can mini retro fridge. Swapped the original power supply for this and it now works again. It doesn’t come with exact instructions but is fairly self explanatory from the swap of the old supply which was labeled. It has only been 24 hours but works great so far!

I got this power supply to replace an included cheap Chinese one in my Frigidaire Mini Fridge that I left out for a couple of weeks due to it didn't cool down my beverages. So far it works great and not having any issues with it.

I've used these in a bunch of one-off industrial automation projects and they are durable and provide clean power. The design is easy to integrate mechanically and electrically. The only downside is you can't easily find their entire product line on Amazon (specifically the power factor corrected ones).

Bought this to replace the stock power unit in my Frigidaire mini fridge. This is better than the original and to me keeps the fridge colder.
