## Description

## NOCO GB50: portable battery jump starter 1500A (12V)

The NOCO Boost XL GB50 is aimed at drivers whose diesel has outgrown the GB40: it covers diesel engines up to 4.5 L and petrol engines up to 7.0 L, which takes in large SUVs, pick-ups and vans. Up to 30 jump starts per charge give you margin for repeated attempts.
Versus the GB40 you get 1500A instead of 1000A, a 35 Wh battery instead of 24 Wh and a 200-lumen torch; recharging takes 4.5 h with a 2A USB charger. If your diesel passes 4.5 L, move up to the GB70, rated for 6.0 L diesel and 8.0 L petrol.
The GB50 keeps 2V detection, manual override and USB power bank use.
