## Description

## NOCO GB500+: commercial jump starter 6250A (12V/24V)

The NOCO Boost MAX GB500+ is for mixed fleets and heavy-duty sites where both 12V and 24V vehicles turn up: a selector with an indicator lets you choose the voltage, and it starts petrol and diesel engines up to 45 L with 6 to 16 cylinders, from class 8 trucks and buses to motorhomes and farm, construction or mining machinery.
If you only ever deal with 12V, the GB250+ (5250A, 16 L) is enough; for 24V-only work the GB251+ (3000A, 32 L) is lighter at 6.17 kg against 8.73 kg here.
It carries a 266 Wh battery, two USB ports, a 12.8V output, a 2200-lumen torch, UltraSafe 2.0, a voltmeter and a 60-second timer; recharge takes 6-8 h.
