I got this on my bench, plugged it in and it didn't explode! It's a really good addition to the bench, particularly for those on a low budget that use USB powered devices. I can use my TS80, function generator, Arduino, etc. all while charging my mobile on the induction coil on the top. I've not tested to see if what is displayed on the screen correlates to actual voltages, but certainly saves having a pile of wall-wart chargers hanging out of the socket, plus you can monitor power consumption.
I may do a few more tests and make a video, since the videos about just now for this are about as useful as a waterproof teabag.
