## Match the model to your engine

Engine size and fuel come first. A small petrol car is covered by the GB20 (up to 4.0 L). Once you have a diesel up to 3.0 L, step up to the 1000A GB40; the GB50 handles diesels up to 4.5 L. Bigger diesels need the GB70 (6.0 L) or the GB150 (7.0 L).

## 12V or 24V

Almost the whole range is 12V. For 24V trucks and machinery there is the GB251+ (3000A, up to 32 L) and the GB500+, which has a 12V/24V selector and 6250A for engines up to 45 L. The GB250+ stays at 12V, with 5250A and up to 16 L.

## Boost X versus Boost

The Boost X series (GBX45, GBX55, GBX75 and GBX155) recharges over 60W USB-C Power Delivery: the GBX45 is full in 0.8 h, the GBX155 in 2.7 h. The classic Boost models use 2.1A USB.

## The AX65 with air compressor

The Boost Air AX65 pairs 2000A peak, for petrol engines up to 8.0 L and diesels up to 6.0 L, with a compressor rated to 100 PSI for tyres up to 35 inches.
