better than expected 44

What I lacked in the technical specifications, is the idle current. While it is of an efficiency of 90% the speech, but agrees that too? So much calmer I was when in the manual for the idle power According to the manual, the device is even for permanent services of 300 W and 600 W peak interpreted when it connected directly to the battery. It's very simple with the supplied clamps. However, the built-in fuse is likely to 600W really survive only briefly.
A laptop and a EQ6 functioned also great in the test.
Now only the endurance test is missing from the box.
