We have this power strip are with us to / under the couch. Adjacent to it are usually two phones for charging and the power adapter from the notebook when it is used in the living room. The two USB ports provide independently of each other up to 2 amps charging current, so are suitable for current mobile phones and tablets, which are not enough the 500 mA of the USB standard. In the earth outlets protection against accidental contact is integrated, which ensures that no individual objects are inserted into the socket. You always have to introduce two "stud" in parallel, as is the case with a connector to get to the power contacts. Thus, the power strip is also safe for children. We are completely satisfied.
