I had the Werk, they work really well, you just gotta figure out the voltage otherwise it take 5 hours to charge 10%.
Would highly recommend using it to charge a battery pack instead and charge the rest of the electronic in the evening.
Think (hope) that the USB werk is a simplified version of the E-Werk that is optimised for phones and the like without any faffing around.
