cheap jump starter pack

I bought the 900amp ones from Supercheap for $79 and it has worked a treat. I use it for running 2 x 12 volt lights by using one of those chaep adaptors. It cetainly is better light and safer than the old gas bottle. I don't know why I waited so long to get one.

Cheers,

Bought a cheap Dick Smith one for about $50. Weighs nothing can be charged on mains or off 12v and has enough kick to start an old diesel tractor in winter (which is what i bought it for) have also run a 12v water pump off it for a few hours without running it down. Though who knows how long something that cheap will last. Would probably think twice about heading anywhere remote with it but for what i use it for don't think you could spend a better 50 bucks

Go with the one with the most amp/hrs, as non of the info you have given has that info, probably 10amp or 17amp for that price. If your light draws 1 amp then a 10 amp batt should run your light for 10 hrs.

Got one from Ray's Outdoors, 17 amp battery, a built in compressor, light and jumper leads. $70.

glenno, a 4 watt fluro won't give you much light. Most of the 12v fluro lights everyone uses for camping are either 12 watt or 13 watt lights. That means they draw about 1 amp/hr.

If the battery would truly last about 50 hrs powering a 4 watt light, that indicates it is probably a 17 amp/hour battery. These are only std led-acid batteries so are not designed to be discharged more than 70 of capacity - or 11 to 12 amps. So with one 12 watt light, you'll get about 10 to 12 hours, depending on wiring, light efficiency etc. You can discharge further but will reduce the battery's overall life considerably.

Also, you mention above that it has 200 CCA. That won't start an electric scooter, let alone a 4x4, so if you want it as an emergency jump-start pack as well, you'll need something with at least 400 to 600 CCA.
