The NOCO Boost GB40 is a pocket-sized lithium jump starter that lets you start a car with a dead battery without waiting for a stranger and a set of cables. When we checked Amazon on November 3, 2026, it was the #1 Best Seller in Jump Starters and #19 in all of Automotive, with 4.6 stars from 130,421 ratings and "30K+ bought in past month." It's not a stocking stuffer at about $100, but it's one of the few gifts that can rescue someone on a cold winter morning, and that makes it an easy pick for new drivers, commuters and anyone with an older car.
Price check
On November 3, 2026 at 12:05 PM CST, Amazon showed the NOCO Boost GB40 at $99.95, in stock, shipped and sold by Amazon.com. No list-price discount was shown, so this is the everyday price of a long-running best seller, not a markdown. Amazon's holiday return window applies: eligible items bought between November 1 and December 31, 2026 can be returned until January 31, 2027. Prices change, sometimes several times a day, so check Amazon before you buy.
What it is, in plain terms
A jump starter is a battery pack with clamps attached. Instead of finding a second car and running jumper cables between the two, you clip the GB40 straight onto the dead battery, press the power button and start the engine. It's small enough to live in a glove box or under a seat. Here's what the Amazon listing and its product photos say about it:
- Power: 1000 peak amps of lithium power, for 12-volt vehicles.
- Engine size: rated for gasoline engines up to 6.0 liters and diesel engines up to 3.0 liters.
- Starts per charge: up to 20 jump starts on one charge.
- Safety: NOCO's "UltraSafe" design, with patented spark-proof connections and reverse polarity protection. The listing calls it foolproof for any 12V vehicle.
- Power bank: a built-in USB port to charge phones and tablets. The photos show a 2.1A USB-A output and a 10W USB-C input.
- Recharge time: about 3 hours, per the listing.
- Flashlight: a 100-lumen LED with 7 light modes, including SOS, blink and strobe.
- Toughness: an IP65-rated housing with rubberized over-molding against water, dust and drops.
- Size: described as 2.5 lb and sized for glove boxes and emergency kits.
- In the box: the GB40, heavy-duty clamps, a USB-C charging cable and a microfiber storage bag. The photos label the clamp cable at about 23 inches and the USB cable at about 24 inches.
- Warranty: 1 year, and the listing says it's engineered in the USA.
Why it makes a smart Christmas gift
Most gifts are about fun. This one is about the morning it saves. Car batteries struggle most in cold weather, which is exactly when a December or January gift is opened. A dead battery in a parking lot usually means waiting for roadside help or asking a stranger for a jump. With a GB40 in the car, the driver can fix it alone in a couple of minutes.
It also suits the people we worry about. Parents buy jump starters for teenagers with a first car and for college students driving home for break. Grown kids buy them for parents who drive older cars. Anyone with a boat, motorcycle, ATV or tractor that sits for weeks between uses gets something that earns its glove-box space. The listing names cars, trucks, motorcycles, SUVs, boats, ATVs, RVs and vans.
The safety design matters most for a gift. Old-fashioned jumper cables come with rules about which clamp goes where and in what order, and getting it wrong can cause sparks. NOCO built the GB40 around spark-proof and reverse polarity protection, so the person you give it to doesn't have to remember those rules under pressure.
Which NOCO Boost should you buy?
The GB40 is the middle of a family. NOCO's comparison chart on the Amazon listing showed these models and prices on November 3, 2026:
| Model | Peak amps | Gas / diesel engines | Starts per charge | Price seen |
| GB20 | 500A | Up to 4.0L gas, no diesel listed | Up to 20 | $79.95 |
| GB40 | 1000A | Up to 6.0L gas / 3.0L diesel | Up to 20 | $99.95 |
| GB50 | 1500A | Up to 7.0L gas / 4.5L diesel | Up to 30 | $149.95 |
| GB70 | 2000A | Up to 8.0L gas / 6.0L diesel | Up to 40 | $139.99 |
| GB150 | 3000A | Up to 9.0L gas / 7.0L diesel | Up to 80 | $299.95 |
For most sedans, small SUVs, crossovers and motorcycles, the GB40 is the sweet spot. It covers far more engines than the GB20 for about $20 more, and it has by far the most ratings of the family, at 130,421 against 31,158 for the GB70. If the person drives a full-size V8 pickup or a diesel truck, step up. On the day we checked, the GB70 was actually cheaper than the GB50, with a brighter 400-lumen light and a 12V power port, so compare both prices before you choose a bigger model.
What Amazon reviewers say
With more than 130,000 ratings, the review picture is clear. Amazon's AI summary of the customer reviews says people find it a powerful little charger that starts cars instantly and is easy to store and use. Amazon also breaks down how many reviewers mention each topic:
- Quality: about 7,700 reviewers mention it, and roughly 6,700 of those mentions are positive.
- Starting: more than 1,100 mention how fast it starts the car, and about 1,070 of those are positive.
- Compact size and portability: both are strongly positive, which fits a pack meant for a glove box.
- Power: about 2,300 mentions, mostly positive, though roughly 650 say it wasn't enough for their vehicle.
- Battery life: this is the split. Of about 4,000 mentions, roughly 2,060 are positive and 1,910 are negative. Some owners say it holds a charge for a long time; others say their unit stopped taking a charge.
- Value and reliability: Amazon describes the feedback here as mixed.
That balance is honest and useful. Most owners are happy, but a jump starter is a battery, and batteries age. Treat the 1-year warranty as part of the purchase and register it.
What to know before you buy
- Charge it before you wrap it, and keep it charged. A jump starter only works if it has power. Recharge it every few months and after each use.
- Match it to the engine. The 6.0L gas and 3.0L diesel ratings are the limit, and some reviewers with big engines say it struggled. Large diesel trucks need a bigger model.
- The clamp cables are short. The photos show about 23 inches, and some reviewers wish they were a little longer. You'll set the pack on the engine or battery while you work.
- It's an emergency tool, not a battery fix. If a battery keeps dying, it's probably worn out or the car has a charging problem. The GB40 gets you moving, so you can get it checked.
- Some spec fields don't match. One line on the listing gives the item weight as 225 g, while the feature list says 2.5 lb. Go by the feature list and photos, not that one field.
- Read the manual once. NOCO includes instructions, and it's worth reading them together with the gift recipient before they ever need it.
Who it's a good gift for
- New and teen drivers. The spark-proof design means fewer ways to get it wrong.
- College students and commuters. It fits in a backpack or glove box and charges a phone in a pinch.
- Parents and grandparents with older cars. Winter is hard on aging batteries.
- Boat, motorcycle, ATV and RV owners. Vehicles that sit for weeks are the usual dead-battery suspects.
- Anyone building a winter car kit. Pair it with our HotHands hand warmers review, a LHKNL rechargeable headlamp and a Carhartt A18 beanie for a full roadside bundle.
Gift tips
- Charge it fully first. Then it's ready the moment it goes into the car.
- Keep the microfiber bag. It holds the clamps and cable together so nothing is missing on a dark roadside.
- Add a note on the engine limit. If they drive a big truck, swap for a GB50 or GB70 before Christmas while the holiday return window is open.
- Stock the glove box. A USB-C cable and a small flashlight round out the kit, though the GB40 already has a 100-lumen light built in.
Our verdict
The NOCO Boost GB40 is a practical gift that can save someone's morning. It delivers 1000 peak amps, up to 20 starts per charge on gas engines up to 6.0 liters and diesels up to 3.0 liters, and it's spark-proof and reverse-polarity protected, so it's safe for beginners. A USB power bank, a 100-lumen flashlight and an IP65 housing make it more useful than plain jumper cables. Amazon shoppers back it with 4.6 stars from 130,421 ratings, the #1 Best Seller spot in Jump Starters and 30K+ purchases in the past month. Battery life reviews are split, so keep it charged and register the 1-year warranty. At about $100, it's one of the most useful gifts on our Christmas list.
Frequently Asked Questions
What size engine can the NOCO GB40 start?
The Amazon listing rates it for gasoline engines up to 6.0 liters and diesel engines up to 3.0 liters, on any 12-volt vehicle. For bigger diesels, NOCO's own comparison chart points to the larger GB50, GB70 or GB150.
How many jump starts do you get per charge?
Up to 20 jump starts on a single charge, according to the listing. Real-world results depend on the engine size, the temperature and how dead the battery is.
Is the NOCO GB40 safe for beginners?
That's the main selling point. The listing says it has patented spark-proof and reverse polarity protection, so connecting the clamps the wrong way round won't send power to the battery. You should still read the manual and follow the polarity markings.
Can it charge my phone?
Yes. It doubles as a power bank. The listing photos show a 2.1A USB-A output for phones and tablets and a 10W USB-C input for recharging the GB40 itself.
How long does it take to recharge?
The listing says it recharges in 3 hours over the included USB-C cable. Top it up every few months so it's ready, since a jump starter that sits empty in a glove box can't help anyone.
What comes in the box?
The GB40 jump starter, heavy-duty clamps, a USB-C charging cable and a microfiber storage bag. The listing photos show the clamp cable at about 23 inches and the USB cable at about 24 inches. It's backed by a 1-year warranty.
Is it a good Christmas gift?
For new drivers, commuters, college students and anyone with an older car, yes. When we checked on November 3, 2026, it was the #1 Best Seller in Jump Starters with 30K+ bought in the past month, and eligible items bought November 1 to December 31, 2026 can be returned until January 31, 2027.
