The NOCO GBX155 is part of NOCO's Extreme Series — a ground-up redesign built for maximum power and speed. At 4,250 amps, it handles gas engines up to 10.0L and diesel up to 8.0L, and recharges from 0% to jump-ready in just 5 minutes via USB-C.

• 4,250A peak current — gas engines up to 10.0L and diesel up to 8.0L; cars, trucks, ATVs, boats, RVs, SUVs, tractors, and more.
• Ultra-fast USB-C recharge — fully charges in 2.7 hours; 5 minutes of charge is enough to jump start.
• 60W USB-C Power Delivery — powers phones, tablets, laptops, and wearables both in and out.
• Enhanced UltraSafe technology — spark-proof, reverse polarity protected, with improved thermal efficiency and power management.
• Extreme Series design — not an upgrade, a completely new platform built for maximum energy release at every start.
