starter power pack

Hi Guys
I saw an advertisment for a power pack that you plug into your cig lighter when your CAR wont start due to a flat battery.
So just wondering if something like that would work on the 80 Cruiser with its 24v starting system and 12V electrics.
Would you need a 24V pack but I dont think so as the electrics are 12V or a 12v pack but then you need 24v to start the cruiser.
And would a pack have enough power to start the cruiser in the first place.
cheers

John,
These power packs are a smaller battery in a box, usually about
17 AH. They plug in to your accessory socket and the charge of the
batteries tries to equalise, so your car batteries get a small charge
from the power pack, usually enough to start a car. Probably not
enough to start a croozer. The cruiser has two batteries so the
benefit would be halved, so the need is for a power pack twice as big.
You also have to leave the pack connected for a while for this
transfer to happen. The other downside is that the pack is a battery,
this needs its own maintenance and has a life expectancy.
With the cruiser starting system you can have a problem when one
of the batteries is bad. You do not know which one it is.
When I had a starting problem coming back from Iceland jumping
the battery on the drivers side was enough to start the car, this is
the Toy recommendation when using another vehicle. When using stand
alone batteries it does not matter.
If you want to go along this route then the simplest way is to
get two small batteries, keep them charged and make two lightweight
sets of leads. When you can't start connect the batteries and wait
half an hour, disconnect them and try to start.
Given that a dead car battery still has about 10 volts in, you
could connect a good battery, or a car, and you would have 23 volts,
over half of it with a lot of power. I have not tried this out but I
suspect this would always get you started.

He means the battery on the right, when in the car looking forwards.
The one on which the -ve lead is connected to the body.
Toyota say don't use the one on the left because when you turn the key
to start the negative terminal on that is at +12v, and its positive at
+24v. That way if the car from which you are jump-starting is touching
your bodywork you will get a major short-circuit!

| But which side is that? You drive left, we drive right.
