I have a manual pump as well.  Though I do have a 12v motorcycle battery in my field box for the starter and as a glow backup I prefer a remote glow driver.  Don't usually have to charge that at the field.

Now, with my gas engines I take a fuel can with a manual pump and a reenforced leather glove.  No starter, starter battery, glow driver, etc.  Just fuel it up, flick the ignition switch on and hand-spin the prop.  Ahhhhhh.
