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. |
