I've jump started lots of cars over the past 30 years and was super skeptical of these at first. They are pretty incredible. 3-4 starts off of one charge easily and make for a hell of a battery pack.
Just mind the size because they are quite a bit chunkier than average power packs.
edit: I’ve bought a few of these as gifts. I *strongly* prefer the ones with a molded softshell case to manage the jumpers. I haven’t found any from a well-known brand that weren’t just re-badged noname products with a big mark up. Project Farm on YouTube has some of the best product reviews out there, it looks like he’s done a bit of a bake off, might be worth your while watching if you’re looking at these.
I bought one off of Amazon that stopped working after three months, extraordinarily frustrating. Hard to find a decent brand since they all seem to be cheap junk.
This thread reminded me that I was thinking about picking one up, I just looked again and it’s almost impossible to pick from the offerings that are out there.
Can you give an example of one? It blows my mind that this is possible - I mean not the technology exactly, that makes sense, but just that something reasonably portable that I would carry around in case my phone dies can also have the level of utility of jumping my vehicle in a pinch.
The battery packs for jumping cars (at least the ones I've seen) are generally more of a size appropriate for putting in a trunk than a backpack or pocket.
I had one a while ago when road tripping in the US, served me a few times, it won't fit in your average jeans pocket but it easily fits in a jacket, you could fit 20+ in your glovebox
