Protective function:
Short circuit protection. The power supply can resume normal operation when the short circuit is removed.
Overcurrent protection. After the overcurrent fault is removed, the power supply will automatically resume normal operation.
Overvoltage protection. When the output voltage exceeds the rated voltage, the power supply will be protected and normal operation can be resumed after the fault is removed.
Two conditions that must be met to select a power adapter:
1. The output voltage(DC 12V) of the adapter must be the same as the rated input voltage of the load (mobile device), or within the acceptable voltage range of the load (mobile device), otherwise it may burn the load (mobile device).
2. The output current (4A) of the power adapter should be equal to or greater than the current of the load (mobile device) to provide sufficient power.

Used to power LED strips, works well.
Works well, no issues so far. Exactly what you would expect for a power supply.

Great power supply
Very pleased with the quality of this power supply. It comes with a 5.5mm connector but also supplied is a jack connector with two terminals for connecting bare wires for a an item that does not have a plug in female connection. Nice bright blue led also.

So far so good
Have used this 2 replace a 2amp supply for 2 CCTV ptz cameras. 2amp was being drawn down when both cameras was rotating at the same time. This has cured this problem because they are on a split cable and both are getting the draw of power they each require.People complained about the blue ðµ. But for me it’s a great idea as the CCTV is in a residential home and it’s in a place that needs to be seen if it’s working.Definitely recommend as a higher ampage replacement.

Works well for my Dell S2240Lc monitor
I rarely wrote a feedback for products (which I should do more often), but I just want to say that this product works well for my Dell S2240Lc monitor. If you ever buy a used monitor that doesn’t come with a power supply adapter like me. The key things are to look for voltage (must match!), amp (can be greater than or equal to the monitor’s requirement), polarity (must match as well), and the port size (this power supply adapter can fit both 5.5 mm * 2.5 mm and 5.5 mm * 2.1 mm as described). I was pretty nervous at first to buy a replacement power supply that is not a real/official one. But hey, power supplies are power supplies, as long as you get the specifications I described above to match with the specifications of the real monitor power supply (which you can find from the user’s guide), you are all set!
