Has anyone every used one of these to start a bird?

[hippieforever3]

I'm still in search of an economical way to ABSOLUTELY quickly get
started after dry camping.

I'm a little paranoid because we accidently turned on the security
lights one night and had to wait the entire next day for a jump.
Couldn't get the genset to charge the batteries enough within a few
hours.

Has anyone ever used something like either of these two items to
start a bird?

I used to have one like the first item to start my tractors after
sitting for a week or two but am curious if they would provide a
nearly immediate start as long as the genset came alive.

If you take the time to read the manual of the second item, it could
be rigged up to autostart the genset with a minimum of trouble.

Movin on,
