Best Lithium Jump Starters

Lithium jump starters have replaced bulky lead-acid boxes because they pack serious cranking power into a unit small enough to live in your glovebox. They stay light, hold their charge for months between uses, and double as a power bank when you need one.

1. NOCO Boost Plus GB40: Best Overall

The NOCO GB40 is the unit most drivers reach for first because it covers the broad middle of the market without fuss. Its 1000 amps will turn over most four and six cylinder gas engines and small diesels with ease.

The spark-proof clamps and reverse polarity warning make it safe for first-time users. It holds its charge for up to a year, so it is ready whenever a battery dies.

• 1000 amps of cranking power for most cars, SUVs and small trucks
• Spark-proof clamps with reverse polarity protection

2. NOCO Boost HD GB70: Best for Big Engines

When the GB40 runs out of muscle, the GB70 steps in with 2000 amps aimed squarely at big trucks, vans and diesel engines. It carries the same safety features but with thicker clamps and cables that move more current.

It is the natural pick for anyone running a workshop or a fleet where the next dead battery could be a heavy V8. The larger lithium pack also keeps your devices charged on long jobs.

• 2000 amps handles large V8 trucks and 6L diesels
• Heavy-gauge clamps and cables for high current delivery
• Rugged housing built for shop and trail use

Pros: Massive cranking power for trucks and diesels; Tough enough for daily fleet duty
Cons: Heavier and bulkier than smaller models

3. Gooloo GP4000: Best Value

The Gooloo GP4000 delivers a lot of cranking power for the money, making it the smart choice for drivers who want headroom without overspending. Its 4000 peak amps will start most engines you are likely to own.

USB-C in and out means it recharges quickly and tops up phones at speed. The clamps and safety cut-offs cover the basics that matter most in a roadside jump.

• 4000 peak amps for large engines at a sensible cost
• Quick-charge USB-C input and output for fast top-ups
• Bright LED light with strobe and SOS modes

Pros: High amp output without a premium outlay; Fast USB-C recharging both ways
Cons: App and display features are basic

4. Hulkman Alpha85: Best Smart Display

🛒  Check Price on Amazon →

The Hulkman Alpha85 stands out for its bright color display, which shows exactly how much charge is left and walks you through a start. That readout takes the anxiety out of a roadside jump.

With 2000 amps on tap it handles cars, trucks and most diesels, and it recharges itself faster than many rivals. It is the unit to pick if you like data at a glance.

• Full-color screen shows charge level and start status
• 2000 amps for cars, trucks and most diesels
• Fast self-recharge from a low battery

Pros: Clear screen removes guesswork before a jump; Quick to recharge itself when low
Cons: Screen draws a little extra standby power

5. Avapow A58: Best High Amp

🛒  Check Price on Amazon →

The Avapow A58 chases raw output with 6000 peak amps, putting it at the top end for cranking power among lithium units. It is built for big diesels, equipment and anyone who needs repeated starts in one session.

That capacity makes it heavier than a pocket model, but the trade is real muscle. The smart clamps and protection circuits keep those high currents in check.

• 6000 peak amps for the largest gas and diesel engines
• Heavy clamps with smart protection circuitry
• Large lithium pack also runs as a power bank

Pros: Enormous cranking output for heavy machinery; Plenty of reserve capacity for repeated starts
Cons: Overkill for small commuter cars

6. DBPOWER 800A: Best Budget

🛒  Check Price on Amazon →

The DBPOWER 800A is the easy recommendation for drivers who want a dependable lithium starter without spending much. Its 800 amps cover most commuter cars and small trucks on a single charge.

It is light, slim and simple, with a flashlight and USB ports for everyday use. For a daily driver that just needs an occasional rescue, it does the job well.

• 800 amps covers most everyday cars and small trucks
• Pocket-sized and light enough to carry anywhere
• Built-in LED light and dual USB charging ports

Pros: Very affordable entry into lithium jump starters; Tiny footprint that fits any glovebox

Frequently Asked Questions

How long does a lithium jump starter hold its charge?

Most quality lithium jump starters hold their charge for several months to a year when stored. It is still wise to top them up every few months so they are ready when a battery dies.

Are lithium jump starters safe to use?

Yes. Modern lithium units include reverse polarity protection, spark-proof clamps and overcharge cut-offs. Connect the clamps to the correct terminals and follow the unit’s lights or screen before starting.

How many amps do I need to jump start my car?

Most four and six cylinder gas cars start fine with 800 to 1000 amps. Large V8 trucks and diesels benefit from 2000 amps or more, so match the rating to your biggest engine.
