NOCO GB40 vs Weego 44s: Which Is the Best Portable Jump Starter?
Quick Answer: The NOCO GB40 and Weego 44s are both excellent portable jump starters — but they’re built for different buyers. The Weego 44s wins on raw peak amps (2100A vs 1000A), bigger engine support, lighter weight, and longer cable reach. The NOCO GB40 wins on brand trust, a larger ecosystem, and slightly more diesel support per dollar. If you drive a standard car or midsize SUV, the Weego 44s is the better overall value at $79.89. If you want the most recognized name in portable jump starters and an established support network, the NOCO GB40 at ~$99.95 is a rock-solid choice.
Your car dies in a parking lot. Nobody’s around. You reach into the glove box — and you’d better have the right tool. That’s the moment that separates a good jump starter from a great one.

The NOCO Boost Plus GB40 is one of the best-selling jump starters in Amazon’s entire automotive category. It delivers 1000 peak amps of starting power from a compact, 2.4-pound unit. It’s rated for gas engines up to 6.0L and diesel engines up to 3.0L.
NOCO launched the GB40 back in 2015, and it’s been a bestseller ever since. The brand has built a reputation for premium quality and their patented UltraSafe Technology — which means spark-proof clamp connections and reverse polarity protection built right into the unit. Even if you clip the cables on wrong, it won’t spark or damage your car.
The GB40 handles up to 20 jump starts on a single charge. It includes a 100-lumen LED flashlight with seven modes, including SOS and emergency strobe. There’s also a USB-C port for charging your phone or tablet. The rubberized, IP65-rated casing handles dust, water, and drops without a fuss.
It comes with heavy-duty clamps, a USB-C charging cable, and a microfiber storage bag. It’s backed by a 1-year warranty and designed in the USA. NOCO has sold over 100,000 units on Amazon alone — and the ratings show it.

The Weego 44s is a USA-engineered portable jump starter that punches well above its price. It delivers 2100 peak amps and 440 cranking amps — more raw power than the NOCO GB40 — and it handles gas engines up to 7.0L and diesel engines up to 3.5L. All of that fits into a unit that weighs less than one pound.
Weego was founded in 2014 with a single focus: make the best lithium jump starters that anyone can use safely. The 44s reflects that mission. It uses patented Smarty Clamps with a 30-inch span, a 1.5-inch wide jaw for a firm grip on battery posts, and tapered tips that reach into tight engine bays. The reverse hinge design is clever — it makes the clamps easier to open and hold in position.
One feature that stands out: the 44s includes audio and visual alerts to guide you through the jump process. Lights and sounds confirm a solid connection before current flows. There’s also a Bypass mode (what NOCO calls Manual Override) for zero-volt dead batteries that won’t respond to normal protection circuits. The USB-C port handles phone and device charging too.
The 44s holds its charge for up to one year without recharging — a claim backed by Weego’s lab testing. It recharges in about 2.5 hours with USB-C. The 2-year warranty is better than the GB40’s 1-year coverage. Amazon reviewers consistently call it one of the easiest jump starters they’ve ever used.

Performance and Raw Power: NOCO GB40 vs Weego 44s
The Weego 44s wins the performance category — and it’s not particularly close. It delivers 2100 peak amps and 440 cranking amps versus the GB40’s 1000 peak amps. That’s more than double the peak output.
Here’s the thing about peak amps: they represent a burst of energy that lasts only milliseconds. Cranking amps are what actually matters for most starts — that’s the sustained current delivered over three seconds at 72°F. The Weego 44s lists 440 cranking amps. NOCO doesn’t publish a cranking amp figure for the GB40, which is worth noting.
In real-world use, the GB40 handles the vast majority of daily drivers just fine. If you’re driving a 4-cylinder commuter car or a midsize SUV, 1000 peak amps is more than enough. But if you own a full-size F-150 with a 5.0L V8 — or any truck with a 7.0L engine — the Weego 44s is rated for it and the GB40 is not.
Cold weather adds another layer to this. Both units are IP65-rated and built for tough conditions. But higher peak amps help more in freezing temperatures, where battery resistance spikes and you need that extra burst to get the engine turning. Weego’s field reports from cold-climate users confirm it consistently delivers in sub-freezing starts.
The Weego 44s wins on power. More peak amps, more cranking amps, and a wider engine range. For everyday cars the GB40 is sufficient. For trucks, large SUVs, or cold-weather use, the Weego 44s is the better tool.
Portability and Design: NOCO GB40 vs Weego 44s
The Weego 44s wins here too — and this one might surprise some people. At under one pound, the 44s is barely noticeable in a bag or jacket pocket. The NOCO GB40 weighs 2.4 pounds. That’s more than twice as heavy.
Both are compact by jump starter standards. But the Weego 44s genuinely fits in a glove box without crowding anything else out. The GB40 is better suited for a trunk storage bag or a dedicated gear pouch.
The Weego’s patented Smarty Clamps are a practical advantage too. Their 30-inch cable span reaches deep engine bays without straining the unit. NOCO GB40 clamp cables run about 12 inches — fine for most batteries, but several Amazon reviewers have flagged issues reaching batteries tucked under cover panels or in tight spots.
Design-wise, both units have rugged builds with IP65 protection against dust and water spray. NOCO’s rubberized over-molded casing looks and feels like premium gear. The Weego 44s is more utilitarian in appearance, but the build quality is equally solid. Neither will disappoint in daily use.
Price and Value: NOCO GB40 vs Weego 44s
The Weego 44s wins on value — clearly. At ~$79.89, you get more peak power, a longer cable, lighter weight, and a 2-year warranty. The NOCO GB40 costs ~$99.95 at its standard Amazon price. That’s a $20 difference for a product that delivers less power on paper.
To be fair, the GB40 goes on sale regularly. It’s frequently discounted to around $79.96 during Amazon’s seasonal events. At that price, the gap narrows and the choice becomes more personal — brand preference, warranty period, and clamp length start to matter more.
The Weego 44s also comes with a 180-day satisfaction guarantee on top of the 2-year warranty. That’s a meaningful commitment from a smaller brand. NOCO has a longer track record and a larger service network, but Weego’s USA-based support team gets strong marks in customer reviews for responsiveness.
At standard pricing, the Weego 44s gives you more power per dollar. If you can catch the NOCO GB40 on sale for $80, it becomes a much tighter call. But at full price, the Weego 44s is the smarter spend.
Safety Features and Unique Tools: NOCO GB40 vs Weego 44s
Both units win in different corners here — and this section matters most for new jump starter users. Let’s go through each key feature honestly.
Reverse Polarity Protection: Both have it. Connect the clamps backwards and neither unit will spark or allow current to flow. This is the most important safety feature and both products handle it well.
Anti-spark / Spark-Proof Connections: Both have it. NOCO’s UltraSafe Technology is their patented version. Weego builds similar protection into the Smarty Clamps. In practice, both clamp safely without sparking.
Bypass / Manual Override Mode: Both have it. NOCO calls it Manual Override. Weego calls it Bypass. This mode overrides the protection circuits to allow current to flow to a deeply discharged battery — one that reads zero volts and won’t respond to a normal jump attempt.
Bypass mode disables all safety protections — including reverse polarity and spark prevention. Use it only when the battery reads zero volts and a normal start fails. Do not use it on a battery that shows any voltage at all. Never use it repeatedly on the same battery — this stresses the jump starter’s internal components and voids intended safe operation. Always double-check polarity manually before activating Bypass.
Clamp Cable Length: The Weego 44s wins here. Its 30-inch Smarty Clamps reach farther and grip better. NOCO’s GB40 cables are shorter — around 12 inches — and multiple Amazon customers have noted difficulty reaching batteries in deep engine bays or under access panels. This is a real-world limitation worth knowing before you buy.
Audio and Visual Jump Guidance: The Weego 44s includes a light-and-sound alert system that confirms a solid clamp connection before current flows. This is a thoughtful feature for first-time users. The NOCO GB40 uses indicator lights but no audio cues.
Built-in Voltmeter: Neither the NOCO GB40 nor the Weego 44s includes a built-in voltmeter. If battery health diagnostics matter to you, consider stepping up to a unit like the NOCO GB70 or a dedicated battery tester alongside your jump starter. The UL Solutions portable power pack testing page explains what safety certifications to look for when buying jump starters — a useful read for anyone who wants to understand what’s actually being tested on these products.
For reference on battery safety standards, the U.S. Consumer Product Safety Commission maintains a list of the voluntary safety standards that apply to lithium battery products including jump starters. Both the GB40 and 44s are built within these safety frameworks.
Both units are safe by design. The Weego 44s edges ahead with longer cables, audio guidance, and a clearer labeling of bypass mode. NOCO’s UltraSafe branding is well-earned but the core protection features are equivalent between the two.
Real-World Use Cases: Which One Wins?
- Daily commuter car (4-cyl, 2.0L engine): Either wins easily. Both start this engine in seconds. The Weego 44s is lighter and easier to carry, making it the slightly smarter pick for glove-box storage.
- Full-size pickup truck (5.7L V8 or 7.0L engine): Weego 44s wins. The GB40 is only rated to 6.0L gas — the Weego 44s handles up to 7.0L. Truck owners should choose the Weego 44s for reliable starts.
- Cold weather start (below 20°F): Weego 44s wins. Higher peak amps provide more energy overhead when battery resistance increases in freezing temperatures. One Weego customer from New England reported starting a completely dead battery in January with no trouble. That kind of cold-climate reliability is the Weego’s calling card.
- Work van or fleet vehicle (diesel, 3.0–3.5L): Weego 44s wins. It handles up to 3.5L diesel; the GB40 tops out at 3.0L diesel. Fleet managers should note this difference for mixed fleets.
- Tight engine bay (battery under cover panels): Weego 44s wins. The 30-inch Smarty Clamps reach farther. GB40 users have reported problems with the shorter cable not reaching in tight applications.
- First-time user with no mechanical experience: Tie. Both are beginner-friendly. The Weego 44s adds audio feedback for clamp confirmation. The NOCO GB40 has a near-legendary reputation for foolproof use. Either will work confidently for a non-technical user.
Who Should Buy the NOCO GB40?
- You drive a standard car, compact SUV, or motorcycle with an engine under 6.0L gas or 3.0L diesel.
- You want the most recognized brand in jump starters, with a global service and parts network.
- You catch it on sale for around $79.96 — at that price, the value equation shifts considerably.
- You plan to use the flashlight frequently — NOCO’s 100-lumen, 7-mode LED is notably bright and versatile.
- You want a heavier, more “premium” feel unit that lives in a trunk kit rather than a glove box.
Who Should Buy the Weego 44s?
- You drive a full-size truck, large SUV, or van with engines above 6.0L gas or 3.0L diesel.
- You live in a cold climate and want higher amp output for reliable sub-freezing starts.
- You want the lightest possible option that truly fits in a glove box or coat pocket.
- You’re buying a jump starter as a gift for a teenager, spouse, or older family member who wants easy, guided operation.
- You want a longer warranty (2 years) and a lower entry price (~$79.89).
Who Should NOT Buy Either One?
- If you have a large diesel engine above 3.5L (think heavy-duty commercial trucks, RVs, or industrial equipment) — look at the Weego 70 (700 cranking amps) or the Weego 120 (1200 cranking amps) instead. For diesel fleets, the NOCO GB70 handles 6.0L diesel and is the better tool.
- If you need a battery health diagnostic display or built-in voltmeter — neither product offers this. Consider adding a dedicated battery tester like the NOCO GB-BT100 to your kit.
- If budget is your primary driver and you need bare-bones functionality — the NOCO GB20 at around $50 handles gas engines up to 4.0L and is a perfectly solid option for compact cars.
How to Maintain Your Jump Starter (Battery Care and Storage Tips)
A jump starter that isn’t maintained is a jump starter that fails when you need it most. Follow these habits and your unit will be ready for years. Clore Automotive’s guide on lithium jump starter safe usage is an excellent resource for deeper maintenance best practices.
Charge it monthly. Even if you never use your jump starter, lithium cells slowly self-discharge. Plug it in for a top-up charge at least once a month. Both the GB40 and 44s recharge fully in under 3 hours via USB-C.
Keep it away from heat. Never leave a lithium jump starter in a parked car on a hot day. Interior car temperatures can exceed 140°F (60°C) in summer — well above the safe storage limit for lithium batteries. Store it indoors or in a temperature-controlled space instead.
Don’t leave it deeply discharged. If you use your jump starter and it drops to low charge, recharge it within a week. Leaving a lithium battery deeply discharged for months degrades the cells permanently. You’ll notice reduced charge retention and weaker starts — a sign the battery has been damaged by neglect.
Bypass mode (Manual Override) disables all safety protections. Using it repeatedly stresses the internal battery cells beyond their design limits. Use it only when the target battery is truly at zero volts and a normal start fails. Never use it as a routine starting method. Doing so can shorten the life of your jump starter significantly.
Recharge after heavy use. If you jump-start a large engine — especially one with a deeply discharged battery — the unit draws heavily on its cells. Recharge the jump starter promptly after any demanding use, rather than letting it sit partially drained.
Final Verdict
The Weego 44s is the better overall jump starter for most buyers. It delivers more power, supports larger engines, costs less, weighs less, and carries a longer warranty. If you want the best portable jump starter for everyday use at the best price, the Weego 44s is the clear choice.
That said, the NOCO GB40 earns its place. If you want the most trusted brand name in the category, the GB40’s reputation is rock-solid. Catch it on sale for ~$80 and the value difference shrinks to almost nothing. Both are excellent tools — but the Weego 44s gives you more for your money at standard pricing.
If you own a full-size truck or drive in cold climates regularly, don’t settle for less. Go with the Weego 44s. If brand recognition matters to you and you’re happy to pay a premium, the NOCO GB40 won’t let you down. — Alex Rahman

Frequently Asked Questions
Which is better — the NOCO GB40 or the Weego 44s?
The Weego 44s is the better overall pick for most buyers. It delivers more power (2100 peak amps vs 1000A), supports larger engines, weighs less, and costs about $20 less than the GB40 at standard pricing. The NOCO GB40 is the right choice if you want the most recognized brand name and can catch it on sale around $80.
What is the difference between the NOCO GB40 and the Weego 44s?
The biggest differences are power and size. The Weego 44s produces 2100 peak amps and handles engines up to 7.0L gas, while the GB40 produces 1000 peak amps and tops out at 6.0L gas. The Weego 44s also weighs under one pound versus the GB40’s 2.4 pounds, and includes a longer 30-inch clamp cable versus the GB40’s shorter reach.
Is the NOCO GB40 worth the extra money over the Weego 44s?
At $99.95, the NOCO GB40 is hard to justify over the Weego 44s at $79.89 — especially since the Weego delivers more power. However, if you catch the GB40 on sale at around $79.96, the gap closes and it becomes a reasonable choice based on brand preference and the NOCO ecosystem.
Does the Weego 44s work in cold weather?
Yes. The Weego 44s is rated to work in temperatures as low as -4°F (-20°C). Its higher peak amp output (2100A) actually helps in cold weather, when battery resistance increases and more starting current is needed. Multiple verified Amazon buyers from cold-climate states confirm it starts dead batteries reliably in freezing conditions.
How many times can I use the NOCO GB40 or Weego 44s before recharging?
NOCO rates the GB40 at up to 20 jump starts per charge on standard car batteries. Weego does not publish a specific number for the 44s, but the battery holds its charge for up to one year in storage. After heavy use on a large engine, recharge promptly — both units use USB-C and fully recharge in 2.5 to 3 hours.
