Did you know that one of the top reasons drivers get stranded isn’t engine failure or a flat tire—it’s a dead battery? And it often happens at the worst possible time: early mornings before work, late nights after a long drive, or on cold winter days when your battery struggles most. That’s exactly the problem the NOCO Boost GB70 aims to solve. Welcome back to AutoVated, where we break down auto products with expert analysis and zero fluff. Today we’re diving into the NOCO Boost GB70, a 2000-amp UltraSafe jump starter that also doubles as a portable power bank. I’ve pulled data from expert tests, verified buyer reviews, and industry comparisons to give you the full picture.
The NOCO GB70 packs a serious punch with 2000 amps of peak current, enough to jump-start engines up to 8.0L gas and 6.0L diesel. That covers everything from sedans and SUVs to larger trucks. Its UltraSafe technology means spark-proof connections and reverse-polarity protection—so even if you’ve never used a jump starter before, it’s designed to be foolproof. Beyond starting power, it doubles as a 12V power bank for charging phones, tablets, and other devices on the go, with a recharge time of about six hours. There’s also a 400-lumen LED flashlight built in with multiple modes, including SOS and strobe—handy if you’re stuck at night. Ruggedness is another selling point: it’s IP65-rated for water and dust resistance, wrapped in rubberized over-molding to handle drops and impacts. At just 5 pounds, it’s portable enough for glove box or trunk storage.
Let’s look at the highlights. The 2000A lithium battery delivers strong, reliable jump-starts, and many verified buyers confirm it works on the first try, even in cold conditions. The spark-proof tech adds peace of mind for beginners. Its multi-use design—jump starter, power bank, and flashlight—means it replaces several emergency tools. And its rugged build inspires confidence in long-term durability. On the flip side, a few recurring cons stand out. At around 5 pounds, it’s bulkier than smaller units like the GB40, so it takes more space. Some users reported that while it handles most cars and trucks easily, larger diesels near the 6.0L limit may require multiple attempts. And while it recharges in 6 hours, some competitors now offer faster USB-C PD charging, which this model lacks.
Speaking of competitors, let’s compare. The NOCO GB70 sits between its smaller sibling, the GB40, and the beefier GB150. The GB40 is lighter and cheaper but limited to smaller engines up to 6.0L gas. The GB150, meanwhile, doubles the power at 3000 amps, ideal for heavy-duty trucks—but it’s bulkier and costs significantly more. Against rival brands like the Clore Automotive Jump-N-Carry JNC770R, the GB70 wins on compactness and modern lithium design, while Clore’s lead-acid model offers more reserve power but weighs over 20 pounds. So, the GB70 hits a sweet spot for drivers who want strength without excessive bulk.

When it comes to build quality, NOCO has a solid reputation, and the IP65 rating plus heavy-duty clamps back that up. Long-term owners consistently report reliability across seasons, though like all lithium units, performance can dip slightly in extreme cold. Customer support is generally regarded as responsive, with a U.S.-based service team and a 1-year warranty.
So, who’s the GB70 best for? It’s a strong fit for commuters, road-trippers, and small business owners with mixed fleets who want a single, dependable jump starter for cars, SUVs, and light-duty trucks. It’s less ideal if you regularly deal with heavy-duty diesels or want the lightest, most compact option for a small car.
Verdict: The NOCO GB70 is a strong option. It blends serious power, safety features, and rugged design in a package that works for most everyday drivers. If you want a lighter, budget-friendly unit, the GB40 will do the trick. If you need extreme power for big diesel trucks, step up to the GB150. But for the majority, the GB70 hits the sweet spot between size, performance, and price.
