If you want **one jump box to leave in the trunk and forget about until you need it**, I’d buy the **NOCO Boost Plus GB40**. - **NOCO Boost Plus GB40** - $99.95 (The Home Depot) ### My picks
If you want one jump box to leave in the trunk and forget about until you need it, I’d buy the NOCO Boost Plus GB40.
Best for most cars: NOCO GB40 — 1,000 peak amps, compact lithium design, spark-proof/reverse-polarity protection, and rated for up to 6.0L gas / 3.0L diesel. It's currently around $100. Independent testing found it reliably started a completely dead 4.0L V6 multiple times.
Best if you have a big truck/SUV or diesel: NOCO GB70 — 2,000 amps and substantially more reserve power. I'd choose this if you have a V8, large SUV, or diesel rather than trying to get by with the GB40.
Best if you want maximum capability for the money: GOOLOO GP2000 — 2,000 amps and rated up to 8.0L gas / 6.0L diesel. It's currently about $50, making it a compelling value.
NOCO GB40 - $99.95 (The Home Depot)
GOOLOO GP2000 - $49.99 (GOOLOO)
NOCO GB50 - $149.95 (Walmart)
One caveat: don't obsess over the advertised peak-amp number. Engine size, actual cranking capability, battery capacity, and cold-weather performance matter more than a giant number on the box.
For a normal sedan/crossover, I'd spend the ~$100 on the GB40. It's small enough that you'll actually keep it in the car, and the safety features make it particularly good for occasional emergency use.
If you tell me your car's year, make, model, and engine, I can tell you exactly which size I'd get.

Having a portable lithium jump starter in your trunk is a total game-changer—no flagging down strangers or waiting an hour for roadside assistance.
Top-performing portable jump boxes fall into a few clear categories depending on what you drive and what features you want:

Keeping a portable lithium jump box in your trunk is one of the best modern car hacks—no flagging down strangers or wrestling with tangled jumper cables. The current market standard leans heavily toward compact, high-output lithium-ion packs featuring robust safety protections (like spark-proof tech and reverse-polarity safeguards).
The top portable jump boxes to keep in your trunk, broken down by category, include:
To help narrow down the exact size and power you need, tell me:
If you want **one jump box to throw in the trunk and forget about until you need it**, I’d buy the **NOCO Boost Plus GB40**. - **NOCO Boost Plus GB40** - $99.95 (NOCO) ### My picks
If you want one jump box to throw in the trunk and forget about until you need it, I’d buy the NOCO Boost Plus GB40.
Best for most cars: NOCO GB40 — ~$100. 1,000A, compact, rugged, spark-proof/reverse-polarity protection, and rated for gasoline engines up to 6.0L. Multiple 2026 tests put it among the top choices, particularly for portability.
If you have a large truck/SUV or diesel: step up to the NOCO GB50 (1,500A) or GB70 (2,000A). You don't need this much capacity for an ordinary sedan, though.
Best value if you want more power for the money: GOOLOO has several 2,000–4,000A models that are considerably cheaper. The tradeoff is that I prefer NOCO's established build quality and safety features for something that's essentially emergency equipment.
NOCO Boost Plus GB40 - $99.95 (NOCO)
NOCO Boost GB50 - $149.95 (Best Buy)
NOCO Boost GB70 - $199.95 (Walmart)
GOOLOO GP2000 - $59.99 (Best Buy)
One important tip: don't buy based solely on the giant "4,000A!" number on the package. For a normal car, a quality 1,000–1,500A unit is plenty. More important are good clamps, reverse-polarity protection, and a battery that will still have charge when you need it.
And whichever you buy, check/recharge it every few months—a jump box that's been sitting dead in the trunk isn't much help.
If you tell me your car's year, make, model, and engine size, I can tell you exactly which one I'd put in your trunk.
When choosing a portable jump box to keep in your trunk, modern compact lithium-ion boosters have largely replaced heavy, traditional lead-acid blocks . They are lightweight, hold a charge for months, and double as power banks for your phone.[](https://www.consumerreports.org/cars/jump-starters/buying-guide/)…

The best options depending on your budget and vehicle size include:
A quick trunk-storage tip: Lithium-ion batteries dislike extreme, prolonged freezing or scorching heat. If you live in an area with extreme winters or desert heat, try to bring the unit indoors to top off its charge every few months.

I wouldn't buy the big old-school Clore JNC660 just for trunk duty. It's a very capable professional-grade unit, but its lead-acid battery makes it substantially heavier and bulkier.
Bottom line: For an ordinary sedan, crossover, or small SUV, get the GB40. It's the sweet spot of size, safety, reputation, and enough power. Also, top it off every few months rather than leaving it in the trunk for years.

One caveat: If you drive a full-size truck, large SUV, or diesel, I'd step up to something more powerful. The NOCO GB70 (2,000A) is a better choice for engines up to roughly 8.0L gas / 6.0L diesel.
If you tell me your car's year, make, model, and engine, I can tell you exactly which jump box I'd put in its trunk—and whether the GB40 is enough.

When picking a portable jump box to throw in your trunk and forget about until an emergency hits, modern lithium-ion packs are the gold standard. They are compact, lightweight, hold a charge for months, and double as phone chargers.
The top-tier options to keep in your trunk include:
Widely regarded as a premier compact pick. It pushes 1250 peak amps (good for gas engines up to 6.5L and diesel up to 4.0L), features rugged IP65 dust/water resistance, and utilizes USB-C fast charging that can fully recharge the unit in under an hour. Its UltraSafe technology prevents sparks if you accidentally misclip the clamps.
A long-time favorite featured by publications like The New York Times Wirecutter . Weighing under a pound, it features fantastic, heavy-duty clamps, foolproof connection warnings, and plenty of muscle to handle up to a 7.0L gas or 3.5L diesel engine while easily stowing away in tight compartments.
Excellent value alternatives that frequently rank high in real-world testing. They feature clear digital readouts for battery percentage and deliver robust cranking power for larger displacement engines without breaking the bank.
Quick Trunk Maintenance Tips:
If you let me know the year, make, and model of your vehicle (and whether it's gas or diesel), I can tell you the exact amp rating you need so you don't overpay for power you won't use.
For **most cars, crossovers, and light trucks**, I’d buy the **NOCO Boost Plus GB40**. It’s compact enough to actually leave in the trunk, has 1,000A peak output, and its spark-proof/reverse-polarity protection makes it unusually beginner-friendly.

One important tip: don't buy solely based on a huge "4,000A/5,000A" number on the package. For an emergency trunk device, I care more about reliable starting power, good clamps, safety electronics, physical size, and whether you'll remember to keep it charged.
If you tell me your car's year/make/model and engine size, I can tell you exactly which size I'd get—and whether the GB40 is enough.
