After 15 days the power supply is gone, I can't open a dispute, so don't buy this garbage.
Rather lightweight, it provides the specified 30V/10A (verified), voltage and current displays very accurate. Very good product at a good price, and even comes with some extras like additional cables. The power plug is fine for germany, not as much for Switzerland, but I am used to change them. The english manual is... well, I think chinese would be almost as readable. I think the only important remark is not to turn power on with load (and therefore you should also not turn it off with load). The only negative experience is that the seller wanted to increase the price after I ordered, but wanted me not to state the reason for cancelling the order (which was because he wanted increased price). Still, at the end decided to ship, so I am happy after all. Thanks!
