Portable jump start pack - recommendations please.

Very useful thanks.

I have a smart(er) charger but that only delivers about 1.9A (the label is pretty much indecipherable). So if I want to step up in the charging stakes I would aim for more than

Returning to my question about charging rate, in crude terms your 4A charger (assuming 4A over an hour = 4Ah) takes around 24 hours to fully charge a 50 Ah battery. This would map to 36 hours for a 75 Ah battery.

This moves the question slightly to "what peak rate should I aim for" in an intelligent charger.

All interesting (and possibly expensive) stuff.

Thanks. That looks to be a generally useful tool.

One potential issue is that the leisure batteries are at the far end from the starter battery.

I need to check how long my jump leads are, but probably need 5 or 6 metre.

This has prompted another thought, which I will post upstream.

This thread has prompted another thought.

I have a motor home with 2 lead acid leisure batteries, an on board charger, and a solar panel on the roof.

Assume that I want to charge my car battery fully, not jump start it, would connecting jump leads between the car battery and the leisure battery bring the car battery up and the leisure batteries down? Seems as if it should. Then I could use the mains hook up and the solar power to charge the motor home leisure batteries and the car battery at the same time.

Assuming that would not overload the motor home charging circuits.

Thoughts?

as it happens, so did I :-)

I will charge from any USB - but can take advantage of faster charging if available.

Mine is a Greenkeeper, I think the 2000A model GK-J1202 which is suitable for up to a 6.5L diesel. They also do a 1000A & a 3000A model. I carry one because short journeys in winter often isn't enough to keep the battery fully charged. I always try to make each journey at least 5 miles.
