NOCO GB40: portable battery jump starter 1000A (12V)
The NOCO Boost Plus GB40 is the sensible choice for most everyday cars: petrol engines up to 6.0 L and diesels up to 3.0 L, from superminis to family SUVs with mid-size diesel units. It gives up to 20 jump starts per charge from its 24 Wh battery.
Compared with the GB20 it shares the casing, weight and torch but doubles the peak current to 1000A and adds diesel cover. If your diesel is bigger than 3.0 L, look at the GB50 (1500A, diesel up to 4.5 L) or, for fast USB-C charging, the GBX45 (1250A, diesel up to 4.0 L).
It detects batteries from 2V and can be forced on in manual override mode.
