1. NOCO Boost Plus GB40: Best Overall
The NOCO Boost Plus GB40 is a compact lithium pack that punches above its size, pushing 1000 amps of peak current through heavy spark-proof clamps. Its reverse polarity protection refuses to send power until the clamps are connected correctly, which removes most of the fear from a roadside jump.
Beyond starting engines it works as a phone charger and an emergency flashlight, so it earns its place in the glovebox. The build quality is the standout, with a tough rubberized shell and clamps that grip terminals firmly even in cold weather.
- 1000A peak output starts most gas engines up to 6L and diesel up to 3L
- Spark-proof clamps with reverse polarity protection let beginners connect safely
- Doubles as a USB power bank and built-in 100 lumen LED flashlight with seven modes
Pros: Rugged housing and clamps feel built to survive years of trunk abuse; Strong safety system makes it almost foolproof for first time users
Cons: Smaller battery capacity means fewer jumps per charge than larger packs
2. DBPOWER 800A Portable Jump Starter: Best Value
The DBPOWER 800A Portable Jump Starter leans on a big 18000mAh battery to deliver dependable starts and a long runtime as a power bank. With 800 amps of peak output it covers the everyday gas engines most drivers own, and the bright LED panel adds strobe and SOS modes for emergencies.
It is larger and heavier than the NOCO, but that extra bulk buys more capacity and a clear charge display. For drivers who want a capable all rounder without stretching the budget, it is a sensible pick.
- 800A peak output handles four cylinder and most six cylinder gas engines
- Large 18000mAh battery delivers multiple jumps and plenty of device charging
- Dual USB ports plus a bright LED panel with strobe and SOS lighting modes
Pros: Generous battery capacity gives more jumps and charges between top ups; Easy to read LED display shows remaining charge at a glance
Cons: Bulkier and heavier than the NOCO, so it takes up more glovebox space
Frequently Asked Questions
Will the NOCO GB40 or DBPOWER 800A start a diesel engine?
The NOCO GB40 is rated for diesel engines up to 3 liters thanks to its 1000A peak output, making it the safer choice for small diesels. The DBPOWER 800A is aimed at gas engines and smaller motors, so it is less suited to larger diesel applications.
Which jump starter holds more charge?
The DBPOWER 800A carries a larger 18000mAh battery, so it generally delivers more jumps and more device charging between top ups. The NOCO GB40 trades some capacity for a smaller, more pocketable body.
Are these jump starters safe for beginners to use?
Both include reverse polarity protection and spark resistant connections, so a first time user can connect them with confidence. The NOCO clamps are particularly forgiving, refusing to pass current until they sense a correct connection.
Our Verdict
The NOCO Boost Plus GB40 wins this head-to-head for its higher 1000A peak output, tougher build and class leading safety system, making it the better all round choice and the one we would trust on a cold morning. The DBPOWER 800A still suits budget minded drivers who want a bigger battery for more jumps and charging and do not mind the extra bulk. For more options see our roundup of the best jump starters.
