12V 1500A Jump Starter NOCO GB50

12V 1500A lithium jump starter – NOCO Boost XL GB50

Where the GB40 stops at 3.0 L diesel, the GB50 extends coverage to 4.5 L diesel and 7.0 L petrol. Peak current rises to 1500A and the internal battery grows to 35 Wh, lifting the reserve to as many as 30 starts on a single charge.

The safety and compatibility basics are those of the Boost family: spark-proof clamp connection, reverse polarity safeguard, support for AGM, EFB, gel, MF and flooded 12V batteries, detection from 2V and a manual override when the battery is more deeply drained.

A 200-lumen, seven-mode torch and a 5V, 2.1A USB port complete it. Allow about 4.5 h for a full recharge from a 2A USB charger. The unit measures 196 × 87 × 50 mm.
