I looked into it, and the EH-5B adapter draws more than I expected. 88-117W. While it does not exceed the 120W rating of the VML, it will consume the battery surprisingly fast (IMHO). A VML would run about 1- 1.5h at "room temperature". Extreme cold and extreme heat can shorten the effective life of a charge.
Wait i have a question as I was thinking about doing the same thing. Does the VML consume power with nothing attached to it? Say for example you left the VML on overnight with no plugs attached; would there still be power left in the battery? The only things that would be draining the battery would obviously be the LED light.
thanks!
