It worked for a couple of years, but then it failed
I bought this 5V DC adapter to use with my Raspberry Pi 3B+. It worked great for a couple of years, but now it's just stopped powering up, suddenly. I think there's an internal open circuit because if I bend and twist the plastic outer housing its LED lights up and it delivers 5V out. Unfortunately, once I let go the LED goes out along with the DC output. I think it's an internal physical fault. It's in one of those screwless molded plastic housings, so I don't think I'm going to be able to repair it without destroying its plastic case. Oh well. It was good while it lasted, but only 3 stars because it didn't last very long.

Pretty close to 4A
At 1.25 ohms would be 4A@5V Tested with full length cable = 4.58V at load Cut cable to 16 = 4.83V. Cut cable to 3 = 4.9V. So yes, it will do close to 4A with SHORTER CABLE and better connectors.

great little power supply
i bought one of these to test in spite of the review that suggested it did not put out a full 4 amps. i have not yet tested to see how much current it takes to cause it to shut down but it is perfect for my application which draws 2.5 amps peak. a 3 amp supply is not adequate but this one works perfectly and the short circuit protection is well implimented.the output resumes as soon as the short circuit is removed unlike supplies that require you to reset them by unplugging. this little supply is perfect for my application so i just bought 200 of them.

Not good for Raspberry Pi
Works fine if you dont draw too much current, but as soon as my Raspberry Pi draws more than 1.5 A, the voltage drops low enough to cause a low voltage warning on the Pi. Not well regulated and not really capable of 4A.

It works
Ive used this power supply for multiple projects now. In one project, I powered a LARGE stepper motor that drew over 2amps. That worked great. Ive also used it to power a Raspberry Pi. It has a status LED on the brick to let you know its on and working. It seems to wait for some kind of stabilization before that light and the output comes on, which is reassuring to me. Be aware, the white stripe on the cable is not positive. Its ground. That got me bad once.
