NOCO Boost GB70: 2000A UltraSafe Jump Review: A Practical, Hands-On Look

You’re stuck in a parking lot with a dead car, and all you hear is a click when you turn the key. The NOCO Boost GB70 is one of those jump starters that always makes it to the top of the list for being a great mid-range option. Lots of people are also searching for a portable jump starter, so I thought I’d take a closer look to see if it’s really worth all the hype.

I checked out the NOCO Boost GB70, a 2000A UltraSafe Jump starter, to see if it’s really worth the investment. What caught my attention was its simple yet appealing promise: it’s NOCO’s top 2,000A booster that can give you up to 40 jumps per charge, and it comes with foolproof spark-proof clamps.

My Hands-On Experience

When I first got my hands on it, I thought it felt like a solid, middle-of-the-road choice, without any obvious compromises or cut corners.

The big test was yet to come – using it to jump start a completely dead battery and get a six-cylinder engine running again. The key specification that mattered in this case was the 2000A peak current, and it definitely delivered. When it came to the battery’s capacity, it also lived up to its promises: it could handle up to 40 jump starts on a single charge, and it even had a useful extra feature – it could be used as a USB power bank to charge other devices.

I found myself constantly comparing it to my old setup, and it came out on top every time. The huge improvement in portability was a major factor – it’s a mid-size box that weighs only around 2.4 pounds, which is small enough to fit in a glovebox. That alone made the upgrade feel like it was worth every penny.

As time went on, it became a part of everyday life – whether it was throwing it in the glove compartment for some extra peace of mind during the cold winter months or using it to charge a phone on a long road trip. What made it so hassle-free was the fact that it had UltraSafe spark-proof and reverse-polarity protection, which gave a sense of security and reliability. This protection feature was a major plus, making it easy to use without worrying about any potential risks or damage.

What makes it keep spinning regularly is pretty ordinary, but it’s real. It recharges in about 6 hours, and when you pick it up, it just works. Not having to think about reliability is better than any fancy feature. It’s the simple things that make a difference.

The not-so-perfect parts

One thing I did notice was that it could be a bit lacking when it comes to starting power – we’re talking 2000A peak for engines up to 8.0L gas or 6.0L diesel. Now, it never actually stopped me from getting the job done, but I think it’s something you should be aware of before making a purchase.

The Specs and Features That Count

Stripped of the marketing, here’s what the NOCO Boost GB70: 2000A UltraSafe Jump actually brings to the table:

• 2000A peak. Up to 40 jump starts per charge (8.0L gas / 6.0L diesel).
• UltraSafe spark-proof + reverse-polarity protection. Integrated power bank.
• Recharges in ~6 hours. 400-lumen LED with 7 modes.

Who It’s For (and Who It’s Not)

Buy the NOCO Boost GB70: 2000A UltraSafe Jump if:

• You want a sweet-spot balance of price, power, and features
• You keep a vehicle that sometimes sits unused for weeks
• You want a reliable backup for dead batteries on the go

Think twice if:

• You specifically want either the rock-bottom cheapest option or outright flagship performance
• You only ever drive a brand-new vehicle that never has battery trouble

Final Verdict

When you consider all the factors, the NOCO Boost GB70 is a good choice for a mid-range jump starter. One of its best features is its battery capacity – it can jump start a car up to 40 times on a single charge, and it can also be used as a USB power bank to charge other devices. However, one of the downsides is its starting power, which is 2000A peak, suitable for engines up to 8.0L gas or 6.0L diesel. Overall, I would give it a score of 7 out of 10 for starting power, 8 out of 10 for battery capacity, and 7 out of 10 for portability.

For most people who regularly deal with turning the key and hearing nothing but a dead click in a parking lot, it hits the value sweet spot. If it sounds like the right fit, it’s worth checking today’s price on Amazon.
