So there is a post about hardwiring the D1 which notes you must use the cigarette connector thru a female fitting to ensure 5v dc. Is the same thing true for the D2?

That is true. More specifically, the D1/D2 MUST only see 5V DC at its connector. Hooking 12V to it directly will damage it.

How much current does the D2 draw when charging? Would it be feasible to charge a D2 from the SV EMS D-37 pin 18 that supplies 5V to some sensors and flap/trim position indicators? The EMS limits pin 18 to 300 ma with an internal fuse but would not want to challenge it.

Pin 18 isn't meant for higher-current applications like charging an external device, and the D2 will definitely try to pull more than 300mA (I forget the exact number, but it's higher).

D2 USB wire?
I would like to run a usb cord from the charger.
I have a 2 outlet usb charging plug that I use to charge my I phone and I pad. Why not the D2?
My furnished D2 charger came apart in the 12v outlet, shedding it's plug and blowing a fuse...a very had to find fuse by the way Wink

USB is 5 volts DC out not 12 volts DC.

So for USB, you can use any "standard" cigarette lighter USB charger with a USB-A to mini-usb cable. That'll give you a USB power source that you can use with the D1/D2. It will charge much slower than the 5V barrel connector though.
