Review: Great value. Worked as expeted. - The original adaptor for my photo tent decided to quit working a few days before a planned photo shoot. New OEM was cost prohibitive at close to half of what a new tent set up would cost. I decided to give this a try, but honestly didn't expect much from a quality perspective. I am happy to say I was wrong. This one was equal in durability to the OEM and has worked like a charm. It also doesn't get as hot at the original one. Don't hesitate to consider this as a replacement power supply.
Review: It works great! - Works great! I use this for testing/programming 12v emergency lighting equipment on the bench before installation. The including wire adapter makes things very easy!

### ⭐⭐⭐⭐⭐ Works to Power 5 PC Case Fans
*by I***E on December 11, 2024*

So I have a room on a 2nd floor that is west facing. In the summer, the AC just doesn't cool the room efficiently enough. I got this as a power supply to a 5 PC Fan window exhaust that I made lol. I have run the thing most of the summer and it has held up well and doesn't appear to have any issues.
