12V 1250A Jump Starter NOCO GBX45

12V 1250A lithium jump starter with USB-C PD – NOCO Boost X GBX45

Rated for 6.5 L petrol and 4.0 L diesel engines, the GBX45 suits 12V vehicles of many kinds: cars, SUVs and vans, but also motorcycles, boats, motorhomes and tractors. Its 1250A peak places it between the GB40 and the GB50 of the Boost line, and it weighs less than the GB40: 0.59 kg against 0.74 kg.

The Boost X series is defined by charging speed. A two-way 60W USB-C Power Delivery socket sets the pace: with a 60W charger the 31 Wh battery is full in 0.8 h (4 h at 10W), and five minutes of charging from empty are enough for a jump start. The same port tops up laptops, tablets and phones, and an extra 5V, 2.1A USB-A port is fitted.

The specification is completed by UltraSafe 2.0, a power-saving 60-second timer, a 100-lumen torch and an IP65-rated housing.
