Any tips?

I'm trying a Halfords one right now as a jump starter. It's not what I expected, failed to start my Land Rover, not a nancy car I know, but I wanted a bit more than a long life torch and it did come with jump leads.

This one was purchased and put on charge on Sunday, tried it out this morning.

Am I expecting too much or is it a dud?

TIA

I don't own one, but used one to start my car when the battery was totally dead (3.0 NA 4cyl) and it started it fine. Did you leave it connected for a few minutes before trying to start it? I think this is required to 'boost' the flat battery enough prior to starting.

I wasn't impressed with mine

The 'proper' ones are quite expensive. I'd keep a spare battery on trickle charge personally.

Indeed - Wolf do one for about £300.

the cheaper 20 30 quid ones most of the time will not start a dead flat battery, diesels even harder due to cranking

the moderate ones ive used that seemed to start most things were the sealey ones at about £80, peak cranking power you have to look for

I got one for about £60, which has tyre inflator and mains socket included. It's started a 2.5 Volvo fine, haven't tried anything bigger. It's as well to leave it connected a few minutes first.

Sealey sell avery good one for £150 ish ... i have used my one to start about 10 cars inc big engines and have still not had to charge it again :)

Well it's been on charge for 48hrs straight now, I'll give a go when I get home, thanks for the leaving it connected tip, that could be the answer.
