Lithium Jump Starters

[kaiowas]

I could do with picking up a Lithium jump starter however this looks like one of those products where there's a lot of new and unfamiliar brands in the marketplace making it difficult to pick out the decent products amongst the cheaply made rubbish. A google search just turns up endless fairly typical boilerplate 'review' sites that I usually discount in the belief that they are just designed to push you towards whoever is giving them the biggest referral fee. Has anyone got any real world experience in this area and can point me towards what's good, bad or downright dangerous?

Thanks for the responses, looks like it's going to be a toss up between the NoCo GB40 and GB70. Biggest thing it will probably have to start is a Volvo D5 (2.4L Diesel) so just need to work out how much to trust their ratings and whether I can get away with the 40 or whether I'll need to pay the extra for the bigger one and the piece of mind that it should start anything I throw at it.
