Which NOCO Jump Starter should I choose?

The most important factor is your engine size and fuel type. The GB20 suits smaller petrol cars up to 4.0 litres only, while the GB40 and GB50 handle most everyday petrol and diesel cars. The GB70 and GB150, and their Boost X equivalents the GBX75 and GBX155, cover larger engines found in bigger cars, vans and SUVs. The Boost X models differ from the standard Boost models by offering 60W USB-C power delivery and generally higher-output torches.

If you also need to inflate tyres, the Boost Air AX65 combines a 2000A jump starter with a 100 PSI, 67 litre-per-minute air compressor. For heavy commercial vehicles — lorries, coaches, buses or agricultural machinery — the Boost Max range starts at 5250A for 12V systems with the GB250+, covers 24V systems up to 32 litres with the GB251+, and scales up to 6250A across both 12V and 24V with the GB500+ for engines up to 45 litres.
