AC DC 48V 3A Power Supply Adapter 144W 48V Charger 48V 3A Switching Power Transformers Interface 5.5 x 2.5mm Suitable for POE Routers Switches Control Systems

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.

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.

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!

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.

Exactly what I needed, It works great!

I am powering a POE switch with this, it is exactly what I needed. It is well made and does the job.

Used it to power a directv traveler antenna on my motor home . Works well

It charges my battery but not all the way full, which is very disappointing. And it doesn’t shut off when it finishes charging. But for the price this is what you get.
