RossCoe said:The input jack is recessed and can't be measured. I have a targus adapter kit for AC charging. I'll dig that out and see if they have one compatible.
I believe we already established their MC4 adapter has a 5521 plug on the other end?
You are in possession of the ciggie plug for charging, didn't you say that goes into the same port as the solar one?
And the ciggie port adapter for 12V output, although that plugs into a different port while in use, can't you just see if it fits the input port without anything live?
Or visually compare them?
Or look at / try the AC charger's plug?
How's it going with the manual? I bet contacting Suaoki TS will get a link to a PDF online. . .
