Very pleased
Works great!

Works as described.
Works good and hasn’t had any issues so far. I’ve been using it to power an amp and it work relatively well in that case.

Does what it claims and decent price
The output voltage is spot on and it has been working fine for about a month 24/7 as a replacement for a unit that failed after a power surge. I have not tested to see if it meets the output specs for current delivery as it exceeds the specs I needed. Runs cool. I suppose it's as good as any made in China power supply is.

Not for ebikes.
The specs are in line with what would be required to charge a 48v ebike battery. They match up perfectly in fact. Even the tip is consistent with what I needed. But when I plug it in I get zero signal.to tell me if it In Fact connected and has begun to charge. I will be returning it. Buyer Beware.

Used as power supply for POE camera setup, will power 2 cameras and a POE switch without issue.
Had to setup POE switch and 2 cameras on remote network segment ... I used a WiFi bridge to connect to my main WiFi router,. Just wish it had a way to include a 48v battery for power outages.

Lasted 29 days
Used this to power a POE NVR that the original power supply went bad on. This one lasted 29 days then stopped working. I opened it up to check and see what happened but didn’t see anything obvious. Just no more light and multimeter shows no voltage on the output side of the board. Got a different brand and I’m back up and running. Edit: Changed my review to 3 stars. After my initial 1 star review the seller contacted me and offered a full refund. (I did not ever reach out to them for a replacement or a refund which I probably should have done before leaving a bad review). So although this particular product failed for me the seller offers great service and you can buy from them with confidence.

Not intended use - but works perfectly.
I ended up using this to power an old Dremel jigsaw. The original power board had blown and this matched the voltage and current output - a perfect fit. Added a variable PWM controller and the Jigsaw is good as new! Nice value - and great find!
