Top 10 Portable Jump Starters in 2027 — Best Overall + Best Value

Direct Answer

For most drivers in 2027, the best overall portable jump starter is the NOCO Boost HD GB70 at about $199.95 — a 2,000-amp lithium pack that starts gas engines up to 8L and diesels up to 6L, with the kind of reverse-polarity protection and build quality that has made NOCO the default recommendation at Wirecutter and Popular Mechanics for years.

The best value is the Avapow A58 2,000A at roughly $79 — it delivers genuine truck-capable cranking power, a 24,000mAh power bank, USB-C, and a flashlight for less than half the price of the NOCO. This list is for everyday car owners who want a glovebox safety net, truck and diesel drivers who need serious amps, and DIY mechanics who want a reliable pack that survives years in a cold trunk.

Below are ten real, currently-shipping models ranked on power, safety, and price.

How We Ranked the Top 10

We weighed lab-tested starting power against real-world safety, features, and price, leaning on testing from Wirecutter, Popular Mechanics, CNET, Car and Driver, The Drive, and TechGearLab, cross-checked against NOCO, DeWalt, Hulkman, and GOOLOO spec sheets. Here is how the score breaks down:

• Starting power (peak/cranking amps) — 25%
• Engine size capability (gas/diesel liters) — 20%
• Safety (reverse-polarity, spark-proof clamps) — 15%
• Extra features (USB, light, inflator, display) — 15%
• Build & portability (weight, IP rating, durability) — 15%
• Price-to-performance — 10%

A high peak-amp number on the box means little without safe clamps and an honest engine rating, so we discount marketing claims that real-world tests don't back up.

1. NOCO Boost HD GB70 🏆 BEST OVERALL

Price: $199.95 | Best for: Drivers who want one pack for cars, trucks, and diesels

The NOCO Boost HD GB70 pushes 2,000 peak amps and is rated for gas engines up to 8 liters and diesel engines up to 6 liters, which covers nearly every passenger vehicle and most light trucks. It carries a roughly 24Wh lithium battery, a dual-USB output that doubles as a phone power bank, and a built-in 400-lumen LED flashlight with SOS modes.

The spark-proof clamps and reverse-polarity protection are the reason Wirecutter and Popular Mechanics keep returning to NOCO — you can connect it wrong and nothing happens. At about 2.4 lbs it is heavier than a compact GB40 but still lives easily in a trunk.

Pros:

• 2,000 amps handles 8L gas / 6L diesel with margin
• Best-in-class safety: idiot-proof clamps and clear error LEDs
• Holds charge for up to a year in storage
• 400-lumen light plus USB power-bank duty

Cons:

• Pricier than budget 2,000A packs
• No air compressor or digital display

Verdict: The safest, most trustworthy all-rounder — the one to buy if you only buy one.

2. NOCO Boost Plus GB40

Price: $99.95 | Best for: Compact glovebox insurance for cars and small SUVs

The GB40 is the model that put NOCO on the map: 1,000 peak amps, rated for gas engines up to 6 liters and diesel up to 3 liters. It is small enough to live in a glovebox, weighs about 2.4 lbs, and brings the same UltraSafe reverse-polarity and spark-proof clamp design as its bigger siblings.

A USB port lets it top off a phone in a pinch. It is not for big diesels, but for the average sedan or crossover it is plenty, and it frequently drops to $79.96 on sale.

Pros:

• NOCO safety pedigree at an entry price
• Genuinely pocketable for cars and small SUVs
• Often on sale near $80

Cons:

• Only 1,000 amps — not for large trucks or big diesels
• No display or inflator

Verdict: The smartest compact pick when you don't need truck-grade amperage.

3. Hulkman Alpha100

Price: $159.99 | Best for: Big trucks and frequent multi-jump duty

The Hulkman Alpha100 swings hard with 4,000 peak amps and a large 32,000mAh battery, enough for a dozen-plus jumps on a single charge and for gas and diesel engines up to roughly 10 liters. Its standout is the bright color display showing exact charge percentage and battery health, plus fast self-recharge.

USB-C in/out and a sturdy case round it out. At over 3 lbs it is no glovebox pack, but for a work truck or a household with several vehicles it carries serious reserve.

Pros:

• 4,000 amps / 32,000mAh for heavy, repeated jumps
• Clear color display for charge and status
• Fast recharge between uses

Cons:

• Heavier and bulkier than compact packs
• Overkill for a single small car

Verdict: A workhorse for trucks and multi-vehicle garages that need depth.

4. Avapow A58 2,000A 💎 BEST VALUE

Price: $79 | Best for: Budget buyers who still want real truck-capable amps

The Avapow A58 is the value champion: 2,000 peak amps and a 24,000mAh pack that the brand rates for all gas and most diesel engines, all for around $79 at Walmart. You get USB-C and USB-A outputs, a dual-mode LED flashlight, and reverse-polarity and short-circuit protection.

The clamps and housing aren't as refined as NOCO's, and the engine rating is optimistic at the top end, but dollar-for-amp nothing on this list beats it.

Pros:

• 2,000 amps for about $79 — unmatched price-to-power
• 24,000mAh power bank with USB-C
• Built-in flashlight with emergency modes

Cons:

• Build and clamps feel less premium than NOCO
• Diesel rating is optimistic for the largest engines

Verdict: The most starting power per dollar — the clear value buy in 2027.

5. GOOLOO GT4000S

Price: $149.99 | Best for: Spec-hunters who want fast charging and a big display

The GOOLOO GT4000S lists 4,000 peak amps, a 26,800mAh / 99.2Wh battery, and a rating for 12L gas / 10L diesel engines. It charges over USB-C PD at up to 100W, hitting full in about 1.2 hours, and a 5-minute top-off is enough for an emergency jump. A 3.2-inch display, three USB ports, a 400-lumen flashlight, and IP65 water/dust resistance make it feature-dense.

It weighs under 2 lbs, which is impressive for the capacity.

Pros:

• 100W USB-C charging, full in ~1.2 hours
• 3.2-inch display and IP65 durability
• Light for its capacity at under 2 lbs

Cons:

• Engine-size claims run higher than independent tests confirm
• Menu and display can feel busy

Verdict: A feature-loaded pick for buyers who value fast charging and data.

6. DeWalt DXAEPS14 / Power Station

Price: $169 | Best for: Tradespeople who want a jump starter plus an inflator

The DeWalt jump starter delivers 1,600 peak amps, a built-in air compressor for topping off tires, and USB-A plus 25W USB-C PD ports. It is built like a job-site tool — rugged housing, integrated handle — and the inflator alone justifies the price for many trades. It is bulkier and heavier than lithium compacts, and 1,600 amps trails the 2,000A+ leaders, but the all-in-one toolbox appeal is real.

Pros:

• Built-in air compressor for tires
• Rugged, job-site-grade build
• USB-A and 25W USB-C PD outputs

Cons:

• 1,600 amps is lower than rivals at this price
• Bulky and heavy

Verdict: The pick when you want a jumper and an inflator in one tough box.

7. NOCO Boost Pro GB150

Price: $299.95 | Best for: Heavy-duty fleets, RVs, and large diesels

The NOCO Boost Pro GB150 is the top of NOCO's lithium line: 4,000 peak amps, rated for gas and diesel engines up to 10+ liters. It has the heaviest-gauge clamps and cables here, the same UltraSafe protection as the rest of the family, and the muscle for RVs, large trucks, and equipment.

The trade-offs are weight — roughly 7 lbs — and an MSRP near $374.95 that usually streets around $299.95.

Pros:

• 4,000 amps for 10L+ gas and diesel
• Heavy-gauge clamps and NOCO safety
• Fleet- and RV-grade capability

Cons:

• Expensive and heavy
• Far more pack than a daily driver needs

Verdict: The serious-duty NOCO for big diesels and fleets that can't get stranded.

8. Schumacher Pro Lithium

Price: $199 | Best for: Pro shops wanting a known automotive brand with high peak amps

Schumacher is a longtime name in automotive charging, and its lithium pack advertises a high peak rating up to 4,400 amps with sturdy professional-grade clamps. It is aimed at shop and roadside-service use, with rugged cabling and broad gas/diesel coverage. Schumacher's premium pro units run far higher — some near $446 — so the lithium model is the sweet spot in the lineup.

Pros:

• Very high peak-amp rating for tough cold starts
• Trusted automotive brand with pro-grade clamps
• Shop and roadside durability

Cons:

• Peak-amp marketing outruns continuous real-world output
• Fewer consumer extras than rivals

Verdict: A solid shop-floor choice for buyers loyal to the Schumacher name.

9. GOOLOO GP4000

Price: $89.99 | Best for: Value buyers who want big advertised amps in an ultralight pack

The GOOLOO GP4000 packs a claimed 4,000 peak amps and a 24,000mAh battery into a body that weighs just 1.81 lbs — one of the lightest high-amp packs sold. It is rated for all gas and diesel up to 10L, with dual USB-A plus USB-C output and a flashlight. Real-world testing shows it starts cars easily but doesn't sustain the headline amperage, so treat the rating as a ceiling rather than a promise.

For the price, it is a strong budget alternative.

Pros:

• Extremely light at 1.81 lbs
• 24,000mAh with USB-C and fast-charge USB-A
• Aggressive price under $90

Cons:

• Real output trails the 4,000A headline figure
• Clamps and case feel budget

Verdict: A featherweight budget pack — great value if you read the amp claim with caution.

10. Clore Jump-N-Carry JNC660

Price: $169 | Best for: Pros and cold-weather diehards who trust lead-acid

The Clore Jump-N-Carry JNC660 is the outlier — a sealed lead-acid unit, not lithium — delivering 1,700 peak amps (425 cranking amps) of steady, repeatable power. Mechanics love it because lead-acid shrugs off deep cold and holds up to years of daily shop abuse, where lithium packs can falter in freezing temperatures.

It is heavy (about 18 lbs) and has no USB or power-bank features — it is a pure starting tool. But for reliability in a frozen lot, it has no peer.

Pros:

• Rock-solid cold-weather lead-acid reliability
• 1,700 peak / 425 cranking amps of steady output
• Pro-shop durability for years of use

Cons:

• Heavy and bulky at ~18 lbs
• No USB, light, or power-bank extras

Verdict: The pro's lead-acid pick when cold-weather reliability beats everything else.

Buyer Decision Tree — Which One's Right for You?

What to Look For When Buying a Jump Starter

• Peak vs. Cranking amps for your engine: Match the pack to your largest engine. A 1,000A unit handles most cars; 2,000A covers trucks and small diesels; 4,000A is for big diesels, RVs, and fleets.
• Lithium vs. Lead-acid: Lithium is light, compact, and doubles as a power bank, but can struggle in extreme cold. Lead-acid (like the Clore) is heavy but unfazed by freezing temperatures.
• Safety features: Insist on reverse-polarity protection and spark-proof clamps. This is where NOCO consistently leads and where bargain packs cut corners.
• USB and power-bank extras: USB-C PD, fast-charge USB-A, and a built-in flashlight turn the pack into roadside gear, not just a starter.
• Build, weight, and IP rating: A glovebox pack should be under ~3 lbs; an IP65 rating means it survives rain and dust in a trunk.
• Cold-weather performance: Cold saps both your car battery and a lithium pack — buy extra amperage headroom if you live somewhere that freezes.

One thing that matters less than marketing implies: the headline peak-amp number. Budget brands routinely advertise 4,000A figures that real-world testing doesn't sustain. A trustworthy 2,000A pack with honest clamps and protection will outperform an inflated 4,000A claim on paper.

FAQ

How many amps do I really need to jump my car? Most gas cars and small SUVs start fine with 1,000 peak amps. Step up to 2,000 amps for trucks and small diesels, and 4,000 amps for large diesels, RVs, or equipment. When in doubt, buy more headroom than you think you need.

Will a lithium jump starter work in freezing cold? It can, but lithium loses output in deep cold, and a frozen pack may need warming first. If you live somewhere that regularly hits hard freezes and you start vehicles daily, a lead-acid unit like the Clore JNC660 is more dependable.

Can a portable jump starter charge my phone too? Yes — nearly every lithium model here (NOCO, Avapow, Hulkman, GOOLOO) includes USB-A and/or USB-C outputs and acts as a power bank. The lead-acid Clore is the exception with no USB.

How often should I recharge a jump starter in storage? Top it off every 3 to 6 months. NOCO packs hold a charge for up to a year, but checking each season means it's ready when you actually need it. A dead jump starter is useless in an emergency.

Is it safe if I connect the clamps backward? With a unit that has reverse-polarity protection (NOCO, Avapow, GOOLOO and others), a wrong connection simply won't fire and an error light warns you — no sparks, no damage. This protection is the single most important safety feature to look for.

Lithium or lead-acid — which lasts longer? Lithium packs are lighter and more convenient but degrade over a few years of charge cycles. A well-maintained lead-acid unit like the Clore can serve a shop reliably for many years, which is why pros still buy them.

Bottom Line

For nearly everyone in 2027, the NOCO Boost HD GB70 at about $199.95 is the best overall jump starter — 2,000 amps, the safest clamps in the business, and the build to survive years in a trunk. If price is the priority, the Avapow A58 2,000A at roughly $79 is the best value, delivering real truck-capable power and a USB-C power bank for less than half the cost.

Truck and diesel owners should look at the Hulkman Alpha100 or NOCO GB150, cold-weather pros at the Clore JNC660, and tradespeople at the inflator-equipped DeWalt. Use the decision tree above to route yourself to the right pick by vehicle, climate, and budget.
