Thread: Portable jump starters, any good

I have a 16000mha powerall if a diesel 4wd truck battery is dead flat I have struggled to start even if the unit is freshly charged, despite the fact that it is supposedly rated for diesels. I took the first one back because I thought it was a dud, the 2nd one was not really any better. The guy at repco said they have had a lot of issues with them. It seems fine for smaller petrol cars, and is super compact so handy for boats, but if I were buying again I would look at something else....
