## Description

## NOCO GBX55: portable battery jump starter 1750A (12V)

The NOCO Boost X GBX55 is the middle ground of the Boost X family, for petrol engines up to 7.5 L and diesels up to 5.0 L: big SUVs, vans, boats and tractors as well as ordinary cars and motorcycles.
Compared with the GBX45 it moves from 1250A to 1750A, from 31 Wh to 46 Wh and from a 100 to a 200-lumen torch, at 1.17 kg. Full recharge takes 1.2 h with a 60W USB-C charger (7.2 h at 10W). If your diesel is above 5.0 L, the GBX75 reaches 6.5 L.
As with the rest of the Boost X range, 5 minutes of charging from empty is enough for a start, and UltraSafe 2.0 and a 60-second timer come as standard.
