Is the NOCO Boost GB70 Worth It in 2026?

NOCO's own page for the GB70 states it delivers 2,000 amps and is built for gas engines up to 8.0 liters or diesel engines up to 6.0 liters, with up to 40 starts per charge — figures the Amazon listing states as well. If your vehicle's engine falls within those two ceilings, the GB70 is worth considering regardless of what kind of vehicle it's bolted into; if your engine is above either ceiling, this isn't the right unit no matter how you'd otherwise describe the vehicle.

Updated October 2026.

We did not test this product ourselves; this review is built from the manufacturer's published specifications and Amazon's product listing.

What Both Sources Say

Both the Amazon listing and NOCO's own page for the GB70 state the same core numbers: 2000 amps of starting current, a ceiling of 8.0 liters for gas engines or 6.0 liters for diesel engines on 12-volt systems, and up to 40 starts per charge. Both sources also describe the same two safety features — spark-proof operation and reverse-polarity protection — and the same secondary use as a power bank for personal devices.

NOCO's own page lists the GB70 as designed for "cars, SUVs, trucks, boats, RVs, and more" — a broad category list that doesn't by itself tell you whether your specific engine qualifies. What actually determines fit is the liter ceiling, not the vehicle category: a gas engine at or under 8.0 liters, or a diesel engine at or under 6.0 liters, is within the stated range; anything above either number is outside it, whatever the vehicle is called.

What Only NOCO's Page States

NOCO's own page adds several figures the Amazon listing GarageRated reviewed doesn't mention. The unit is part of NOCO's Boost HD line and weighs 5.0 pounds, per NOCO's page. It's housed in a water- and dust-resistant enclosure NOCO rates at IP65, wrapped in a rubberized over-molded casing. Its secondary functions go beyond the phone/tablet power bank the Amazon listing describes: NOCO's page states the GB70 is good for up to 6 smartphone recharges per charge, and adds a 12V output for powering devices like tire inflators or power inverters — a function the Amazon listing GarageRated reviewed doesn't mention. The built-in flashlight is rated at 400 lumens with seven light modes, including SOS and emergency strobe settings, per NOCO's page.

NOCO's page doesn't state a cable length, a specific USB recharge time for the unit itself, or a warranty term, and its "What's in the Box" section didn't list specific contents when we read it — so none of those are stated here either.

Key Specs

Checking Your Engine Against the Ceiling

The two numbers that actually matter for fit are your engine's displacement in liters and whether it runs on gas or diesel — both are typically listed in your owner's manual or on a label under the hood. If your gas engine is at or under 8.0 liters, or your diesel engine is at or under 6.0 liters, the GB70's stated ceiling covers it, per NOCO's own page and the Amazon listing. If either number is higher, the GB70's published range doesn't cover it, regardless of whether the vehicle is a car, truck, van, boat, or anything else on NOCO's category list. Neither source states what happens if you try to jump an engine above the stated ceiling, so treat the numbers as the manufacturer's stated range rather than a guarantee either way. If you don't already know your engine's exact displacement, it's usually printed in your owner's manual, on a build sticker under the hood, or on the manufacturer's own spec page for your specific vehicle and model year — this page can only tell you what NOCO and the Amazon listing state about the jump starter itself, not about your particular engine.

What Stands Out

• The engine-size ceiling is stated plainly, in liters. Per both the listing and NOCO's page, 8.0L gas or 6.0L diesel is the number to check against your own engine, not a vehicle category.
• It does more than jump a battery. Per NOCO's page, the GB70 also works as a power bank (up to 6 smartphone recharges) and has a 12V output for other devices, on top of the phone/tablet charging the Amazon listing describes.
• The flashlight is a genuine secondary tool. 400 lumens across seven modes, including SOS and emergency strobe, per NOCO's page.
• IP65 and a rubberized casing suggest it's built for rough handling, per NOCO's page, though neither source states a drop rating.
• NOCO describes the spark-proof and reverse-polarity combination as a "mistake-proof design," per its own page — language aimed at reducing the risk of a bad connection when you're jumping a battery in the dark or in bad weather.

Where It Might Not Fit

• Engines above the stated ceiling aren't covered. A gas engine over 8.0 liters or a diesel engine over 6.0 liters is outside the range NOCO and the Amazon listing both state for this unit.
• If you don't need that much ceiling, NOCO's smaller GB40 covers a lower range (up to 6.0L gas / 3.0L diesel, per NOCO's page for that unit) at a lighter stated weight.
• No stated cable length, USB recharge time for the unit itself, or warranty term on either source GarageRated reviewed.

FAQ

What's the largest engine the NOCO Boost GB70 can jump-start?

How much does the GB70 weigh?

NOCO's page states 5.0 pounds. The Amazon listing GarageRated reviewed doesn't state a weight.

Does the GB70 do anything besides jump-start a battery?

Yes. Per NOCO's page, it works as a power bank good for up to 6 smartphone recharges, includes a 12V output for devices like tire inflators or power inverters, and has a 400-lumen flashlight with seven light modes.

Is the GB70 water-resistant?

NOCO's page rates the enclosure at IP65. Neither source states a submersion rating beyond that.

How do I know if the GB70 covers my vehicle?

Check your engine's displacement in liters against the stated ceiling — up to 8.0 liters for gas or 6.0 liters for diesel, per both NOCO's page and the Amazon listing — rather than going by vehicle type alone. Your owner's manual or a build sticker under the hood is the most reliable place to confirm that number if you're not sure.
