NOCO Boost GB40: 1000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack, Portable Jump Box, Power Bank & Jumper Cables - for 6.0L Gas and 3.0L Diesel Engines
Overview
The NOCO Boost GB40 is a compact 1000-amp 12V lithium-ion jump starter that gives drivers a safe, tool-free way to revive a dead battery. It’s aimed at everyday motorists, small-truck and SUV owners, motorcyclists, boaters, and anyone who spends time off-grid — basically anyone who wants reliable emergency starting power without calling roadside assistance. Rated to jump gasoline engines up to 6.0L and diesels up to 3.0L, the GB40 delivers up to 20 jump starts per charge and doubles as a USB-C power bank for phones and tablets. Built-in UltraSafe electronics provide spark-proof clamps and reverse polarity protection, while a 100-lumen LED with SOS and strobe modes makes it a versatile emergency tool to keep in a glovebox, trunk, or tackle box.
Key Features
- 1000-amp peak current (12V) — designed to start gasoline engines up to 6.0L and diesel engines up to 3.0L.
- Up to 20 jump starts on a single charge under typical conditions — useful for multiple-start scenarios or trips.
- UltraSafe electronic protection: spark-proof connection, reverse-polarity protection, over-current and over-charge safeguards.
- Integrated 100-lumen LED with seven modes (high, medium, low, flash, strobe, SOS, and emergency) for visibility and signaling.
- USB-C power bank functionality for charging phones and tablets and USB-C input to recharge the unit — lithium-ion battery chemistry for a high energy-to-weight ratio.
Pros & Cons
Pros

- Clamps and cable length are compact; may be awkward for some battery placements compared to longer-cabled units.

- Weekend adventurers, campers, and boaters who need a lightweight multi-purpose power source (jump-start, phone charging, flashlight).
