Best Jump Starters
Top 5 on Amazon
Our #1 pick is the NOCO Boost GB40. A dead battery in a cold car park is the worst time to shop. We compared five portable jump starters on Amazon, from a pocket NOCO to a heavy-duty Clore pack.
How we picked: we shortlist by Amazon Best Seller rank and number of ratings, then compare published specs. We don't test these products hands-on.

The short answer
For most drivers, the NOCO Boost GB40 is the jump starter to buy. NOCO’s listing says it delivers 1,000 amps of peak lithium power, up to 20 starts per charge on engines up to 6.0 L gas and 3.0 L diesel, in a 2.5 lb box that fits in a glove compartment. It has spark-proof and reverse-polarity protection, so a wrong connection will not throw sparks. It is one of the most-reviewed jump starters on Amazon, and it costs around $100.
Pick by situation. For a bigger truck, SUV or diesel, step up to the NOCO Boost X GBX55, rated at 1,750 amps for gas engines up to 7.5 L and diesel up to 5.0 L, with USB-C charging. For the cheapest decent option, the GOOLOO GP4000 is around $80 with a huge 4,000 amp peak rating. If you also need to top up tires, the GOOLOO A3 adds an air compressor. And for a shop or a farm that wants a no-nonsense pack with heavy cables, the Clore Jump-N-Carry JNC660 is the old-school choice.
Skip the NOCO GB40 if you drive a big diesel truck, since it is rated for engines up to 3.0 L diesel. Skip the Clore if you want something small: it is a lead-acid box that is much bigger and heavier than a lithium pack. And remember that the peak amp number is not the starting power, since brands measure it differently. Compare the engine sizes each listing says it can start, not just the biggest amp number.
How we picked: we compared the popular jump starters on Amazon, what owners say about reliability and cold-weather use, and the specs each listing states. We do not test jump starters hands-on, so this guide reflects the listings and owner reports. Price bands were checked in October 2026.

Why each one made the list
What each pick does best, where it falls short, and the typical Amazon price when we checked.
- 1. Best Overall
NOCO Boost GB40
BeastScore 93 / 100Typically $90–$110 on Amazon (checked October 18, 2026)The GB40 is the jump starter most drivers should keep in the glove box. NOCO’s listing says it gives 1,000 amps of peak lithium power for up to 20 starts per charge on engines up to 6.0 L gas and 3.0 L diesel. It weighs 2.5 lb, so it is easy to stash, and the UltraSafe protection is spark-proof and reverse-polarity proof, which suits nervous first-time users. It doubles as a USB power bank and flashlight with a 100-lumen LED and SOS mode. It will struggle with big diesels and it has no air compressor.
Pros- Spark-proof and reverse-polarity protection for safe use
- Compact 2.5 lb size fits any glove box
- Power bank and 100-lumen light built in
Cons- Not enough for large diesel trucks
- No air compressor or USB-C fast charging
- Rated for 3.0 L diesel at most
- 2. Best for Trucks and SUVs
NOCO Boost X GBX55
BeastScore 91 / 100Typically $160–$190 on Amazon (checked October 18, 2026)The GBX55 is for bigger engines. NOCO says it handles gas engines up to 7.5 L and diesel up to 5.0 L, with 1,750 amps of peak power and up to nine starts per charge. It adds UltraSafe 2.0 protection, a 60-second timer that conserves power, and USB-C Power Delivery at 60 W, so the battery can recharge in about 1.2 hours and even charge a laptop. NOCO also says you can gain enough power for a jump in around five minutes of charging. It costs almost twice the GB40, and it is larger, so check you actually need the extra power.
Pros- Starts gas engines to 7.5 L and diesel to 5.0 L
- USB-C recharging in about 1.2 hours
- 60 W USB-C output works as a laptop power bank
Cons- Costs almost twice the GB40
- Fewer starts per charge than the GB40 on small engines
- Overkill for a compact car
- 3. Best Budget
GOOLOO GP4000
BeastScore 86 / 100Typically $70–$90 on Amazon (checked October 18, 2026)The GP4000 is the value pick. The listing advertises a 4,000 amp peak rating, dual USB charging ports and 10 types of built-in protection, with metal clamps and a rubber-cornered shell that can take drops. At around $80 it is usually the cheapest brand-name jump starter here. A 4,000 amp number is a peak rating and each brand measures differently, so it does not mean it will outstart the NOCO. The listing does not clearly state engine sizes, so match it to your engine carefully and check recent owner feedback.
Pros- Lowest price of the name-brand picks
- Metal clamps and 10 types of protection
- Rugged shell with rubber corners
Cons- Engine size limits are not clearly stated on the listing
- Peak amp figure is not a direct comparison with NOCO
- Fewer safety certifications listed than NOCO
- 4. Best 2-in-1
GOOLOO A3
BeastScore 85 / 100Typically $80–$100 on Amazon (checked October 18, 2026)The A3 does two jobs. The listing describes a 3,000 amp jump starter with a built-in air compressor, five inflation modes (SUV, car, bike, ball and custom) and an LED screen with tire-pressure detection and automatic shut-off. GOOLOO calls it a 7-in-1 device that also works as a power bank. Having both in one box saves space and money over buying a separate inflator. As with the GP4000, the listing does not give clear engine size limits, and a combined unit is bulkier than a pure jump starter.
Pros- Jump starter and tire inflator in one box
- Smart LED screen with auto shut-off on inflation
- Costs about the same as the GP4000
Cons- Engine size limits are not clearly stated
- Bulkier than a pure lithium jump pack
- Newer model with fewer owner reports than NOCO
- 5. Best for Shops and Farms
Clore Jump-N-Carry JNC660
BeastScore 84 / 100Typically $120–$135 on Amazon (checked October 18, 2026)The JNC660 is the old-school workhorse. The listing says it carries 1,700 peak amps, a 22 Ah Clore Proformer battery designed for jump starting, 46-inch #2 AWG cables and a voltmeter that shows the pack’s charge. A 12V DC outlet powers small accessories. It is one of the most-reviewed jump packs on Amazon, and it is built for repeated use in garages and on farms. It is also a heavy lead-acid box with a handle, not something you slip into the glove compartment, and it needs charging every few months to keep the battery healthy.
Pros- Heavy-duty cables and a rugged build for repeated use
- Voltmeter shows the pack’s charge level
- Lead-acid battery tolerates a lot of use
Cons- Much bigger and heavier than lithium packs
- No USB power bank or modern safety features listed
- Needs regular recharging to protect the battery

Quick tips before you buy
Check the largest gas and diesel engine each listing says it can start, not just the peak amps.
A jump starter that is flat when you need it is useless. Check it every 3 to 6 months.
Lithium packs do not like a hot trunk in summer. Store them in the cabin when you can.
Look for spark-proof and reverse-polarity protection, and always follow the manual order.
Quick answers
What is the best jump starter?+
The NOCO Boost GB40 is our pick for most drivers: compact, spark-proof and trusted. For big trucks and diesel engines, step up to the NOCO Boost X GBX55.
NOCO or GOOLOO: which is better?+
NOCO has the stronger safety features and clear engine size ratings. GOOLOO is cheaper and advertises higher peak amps, but its listings are less clear on which engines it can start.
How many amps do I need to jump a car?+
Match the engine size, not just amps. A 1,000 A NOCO GB40 is listed for engines up to 6.0 L gas and 3.0 L diesel. Bigger trucks need something like the GBX55 at 1,750 A.
Can a jump starter work on a completely dead battery?+
Most lithium jump starters have a boost or override mode for batteries that read very low. Check the manual of your model and follow it exactly.
How long does a portable jump starter last?+
Many owners report several years of use if they keep it charged. The lithium packs lose power slowly in storage, so top them up every few months.
Is a jump starter better than jumper cables?+
Yes for convenience. You do not need a second car, and modern packs have spark and reverse-polarity protection. Cables are cheaper but need another vehicle and care.
Can I take a lithium jump starter on a plane?+
Often not in checked bags, and limits apply in carry-on. Check your airline and the TSA rules for lithium batteries before you fly.
