The packaging a load up to 3500 watts is indicated.
Unfortunately, there are 2 negative points:
1 star deduction:
When using the middle socket, can no longer be used one of the two outer sockets, as this is covered by the plug (see photo).
1 star deduction:
The adapter plug is not horizontally plugged into the outlet, but vertically. In a combination of light switches and outlet (eg next to the door), it may happen that the light switch can not be operated (see photo).
The packaging of the adapter plug is very customer unfriendly and can only be opened with scissors or cutters. Note: sharp edges
Who the dots do not interfere with the above, this socket can buy with a clear conscience.
