What is the power supply controversy?
The nice little 5V 2A power supply, Youhong model 1201, turned out to have counterfeit UL and CE markings. These were shipped by us for a while and are shipped by virtually all eBay sellers and are subject to hold and confiscation for destruction by US Customs. If there had been no markings, they would have been OK for the US. Valid CE is required for most of Europe. We sometimes have new supplies that are certified. If you bought from Watterott in Europe, they use a German power supply and there is no problem. There is nothing wrong with the Youhong supply with one exception: There is no fuse inside. We recommend that they be used for lab supplies only and not be left unatended.
