Jump Starting

[cmm303]

I have one of these .. at less than a pound in weight it starts my 3.0 V6 Alphard up OK ..

nifty device, probably takes less space than jump leads! To jump start, do you connect to the van battery with leads supplied and leave for a bit for charge to transfer, then start up?

will it have enough ummmf to start a diesel

I can understand it would be able to start a petrol

I saw these at santa pod last year on a stand

slightly cheaper

I did ask - the same question - the guy stated off course

so I said I would run mine down to flat - go and get him to try my diesel

if it worked I would buy one - even the more expensive one where you bought a kit with it

he just looked at me - shook his head and walked off

charming - I guess there wasn't a refund either if I bought it first and tried it later

My only problem with that is I'm getting fed up with gadgets intended to get you out of a hole occasionally but that turn out to have died when you eventually need them

As dodgey said, simple lead acid batteries (in daily use) and chargers have a lot to commend them. And jump leads don't go flat except when you need to store them

Well, I read the link to that power bank device as I have a particular interest in such devices. I am always on the lookout for power sources to run amateur radio equipment which usually likes a 12v supply.

Many of those multi voltage power banks have a lithium ion battery at around 5 volts and use an invertor to achieve the 12v and 19v output voltages. They are charged from a 5v USB source as often as not. Most I have seen only have 5 volt outputs anyway. As a result of my research I haven't bothered investing in one yet. I'm still with deep cycle sealed lead acid batteries which are unfortunately much heavier than lithium ion or lithium polymer batteries.

I'm not saying that these packs couldn't start a car but bear in mind that a standard warning is never to short circuit such batteries, I would be very surprised if there isn't some sort of current limiting built into the packs.

I suspect that they really start cars by giving the flat car battery a quick rejuvenating charge in the time between you connecting them to the battery and hitting the starter switch. Rather like the so called jumper leads that mate two cars via the cigar lighter sockets, which would melt if they were really starting the car.

Hi
Well....If I manage , one year, to get to a Stourport meet, I'll show you my trick for turning water into wine....AND start a Bongo off a PP3 battery!

.No doubt it involves using a cartridge starter from a Wright Cyclone engine

The PP3 battery is an old trick for starting some old British bike ..

I don't drink so I will pass on the wine ..

I am not a fishy eater .. but my son (Warwick) likes some so maybe a tip on that one ..

To save walking around it .. I could do with a short cut .. across.. our Arboretum lake ...

Remember the old Chipmunk's Gipsy Major engine used to be started using 12 Bore blanks?

Hi Mike...
They're called a Coffman Starter...
A very useful bit of kit used on numerous piston engined 'planes....simple and efficient when you haven't got "mains hook-up"

Hi Bob...
The Coffman Starter on 'planes used a bit more wallop than a 12 bore blank!.... ...

That would sort out any Bongo Naughtiness.

[helen&tony]

Hi
Bob...I've always wanted to have a go at one of those starters...the Coffman system was used mainly on aircraft, but I seem to remember some large car engines had the system...don't quote me, but I am scratching my memory, and seem to remember Napier-Railtons having a system on the racing engines. I should imagine they worked best on the old American radial engines, as they must have been superbly balanced. I remember Dad talking about the Coffman starters...he flew in B24s , which had Pratt & Whitney radial engines, and I guess they may have used them.

Jimmy Stewart in the Flight of the Phoenix .. 'clearing out' the cylinders and only having one cartridge left to fire up the engine ..!!

Coffman Starter

What a lovely onomatopoeic name, bringing to mind massive radial engines coughing into life. Each exhaust puffing smoke in turn.

Mind you, they still cough into life when started with a crank handle as on the Swordfish.

Hi
Onomatopoeia ....a word that brings to mind an incontinent cat that didn't make the dirt box in time
