NOCO GB20: portable battery jump starter 500A (12V)
Pick the NOCO Boost Sport GB20 if you drive a petrol city car, hatchback or small family car with an engine of no more than 4.0 litres. Its 500A peak and up to 20 starts per charge are sized for exactly that job, and at 0.74 kg it lives happily in a glovebox.
It is not the one for diesel owners: the GB20 has no diesel rating at all. For a diesel up to 3.0 L, or a petrol engine up to 6.0 L, step up to the GB40, which keeps the same 24 Wh battery and body size but doubles the peak to 1000A.
Like its bigger brothers it detects batteries down to 2V, offers a manual override and doubles as a USB power bank.
