I tried connecting my EW logger to external 12V power from the glider per instructions in the manual. Current draw was reasonable (150-250 mA), but the unit became extremely hot (I couldn't hold it) and it stopped working for the rest of the day. The next day it functioned normally.

Does anyone have any experience in this area?
Something's wrong with your unit. I use EW almost exclusively with
external power. I also use built-in 12V-5V converter, so there's a lot
of power going through EW. Still no overheating problem.

I suggest writing to Graham from EW, he's a very helpful man and
responds promptly.
