Used to apply a bathroom LED 0.8A, so enough in theory. A passed away after a few weeks of occasional use. So much for the warranty, I opened the case and found that the IC had exploded (the upper CI completely detached and strolling in the housing, visible internal chip and charred). For the rest, the circuit does not seem to have suffered. I suspect my applies (which had already blown his original power) to "pull" in fact more than what is advertised for a very brief moment almost undetectable (start maybe). Direction the trash, outdated security. My concern for this article criticizes the lack of protection in case of intensity overshoot. It would have been relevant for the manufacturer to provide a small fuse see a resettable circuit will automatically protect the power supply against overcurrent. For the rest, the price is hard to beat, quality is "common" (sign of the times, it will always be "made in PRC") and I guess used with standard devices he would fill his office well.
