Great little voltage inverter for the modest price of 8 euros, free shipping I expected a gimmick. But not at all, connected upstream of my heat gun (2000watts) for 15 minutes, he did not flinch, slightly heated, but that's normal. Connected to an old drill without 800watts inverter, I could vary the speed of a few revolutions / m at 1200 rpm / m certainly with a loss of power but reasonable. By cons in a blender, nothing at all, it does not work, I guess the motor type is not supported, I'm no expert in the matter. The connections are simple, the two terminals of the left on the sector, the two terminals of the right towards the machine to be controlled, we can not do more simple and effective. In short, a report / Quality Top price. In addition, I conducted other tests: Connected upstream of a 2000W vacuum cleaner yet been provided with a drive, it works without overheating. Connected upstream of a drill press, no problem, it works. Connected upstream of a halogen projector 2500W is also effective at the end of an hour the controller was just lukewarm. Connected upstream of a shield, it is also effective. This small controller is a marvel of efficiency. The only small, but small problem is the fuse protection, in fact it is on the map and you must remove the cover (2 screws) to be able to replace it, but then I quibble a little.
