I've had a cheapo unknown brand one of these for several years. Over that time I've used it half a dozen times to start cars (up to 2.0 petrol) and it worked every time. Depends, I suppose on how much juice is left in the car battery. Also useful as a power bank to charge laptop, phone, etc. Can be charged from the cigarette lighter socket.

To save you some extreme annoyance, it came out top.

The NOCO GB40 and Harbor Freight Viking, (The latter wont be available in The Yook, at least under that name), came out bottom. The NOCO is probably a smaller capacity than the one mentioned above, and was likely underpowered, especially in the context of your average American engine.

Not a rigorously standardised test, but at least he's stopped wrecking engines for a redneck laugh. Still seems to use the words "volts" and "amps" interchangeably though.

Of course its a one-off test of one example. It tells you nothing about durability or how much they vary due to quality control tolerances, but it probably tells you a bit more than anecdotal experience under hugely variable and non-comparative conditions.

There was a super-capacitor model tested which might be a good choice for durability, though it was bulky and struggled in some of the tests.
