NOCO GB70 vs NOCO GBX75: Which one to get?

In the world of portable jump starters, NOCO is a renowned name, known for its high-quality products that deliver reliable performance. Two of its popular models are the NOCO GB70 and the NOCO GBX75. Both are powerful, portable, and packed with features, but they cater to different needs and preferences. In this article, I have looked into these two jumpstarters closely  to help you decide which one is the right fit for you.

Power and Performance

The NOCO GB70 is a portable lithium-ion battery jump starter that delivers 2,000-amps for jump starting a dead battery in seconds. It is designed for a car, boat, RV, truck and more with gas engines up to 8 liters, and diesel engines up to 6 liters. It can provide up to 40 jump starts on a single charge, making it a reliable companion for long trips.

On the other hand, the NOCO GBX75 is a more powerful model, delivering 2,500-amps. It is designed to jump-start 12-volt batteries in vehicles up to 8.5-liters gasoline and 6.5-liter diesel engines. This includes cars, motorcycles, trucks, ATVs, boats, RVs, vans, SUVs, tractors, and more. The GBX75 is part of NOCO’s Extreme Series, designed to release maximum energy at every start.

Safety Features

Both jump starters feature a safe, mistake-free design. You simply connect the terminals (red to red, black to black), power them on, and the jump starter performs a quick diagnostic. A white LED indicates when it’s ready to start. If the white LED doesn’t light up, you power it down, double-check your connections, and try again. Both models also auto shut down after 60 seconds for safety.

The GBX75 has additional indicator lights that let you know if there’s a problem, such as reverse polarity or a temperature issue. This extra layer of feedback can be helpful in troubleshooting and offers better thermal efficiency and power management for improved performance and longer battery life.

Charging and Power Supply

As with anything battery-operated, before their first use, both jump starters need to be fully charged. They do come with included USB cables for this purpose, as well as vehicle attachments for charging on the go so you can choose which to use – the GB70 uses the older micro USB input for charging, while the GBX75 uses the more modern Type-C USB, enabling it to fast charge. It can completely recharge in just 1.8 hours, or go from 0% to jump starting in just 5 minutes of charge. Aside from being a car battery jump starter, its internal power bank provides 60 watts of power to power your favorite USB-C devices.

As a power supply, the GB70 has a USB and a 12-volt outlet. The GBX75 also has a USB output, but it doesn’t have a 12-volt outlet. This could be a deciding factor depending on your power supply needs and accessories you are running.

The GB70 doubles as a portable power source for recharging USB devices, like a smartphone, tablet, and more, or powering 12-volt devices, like a tire inflator, power inverter, and much more. It can provide up to 6 smartphone recharges.


Additional Features

Both models come with an ultra-bright 400 lumen LED flashlight with 7 light modes, including SOS and emergency strobe. This feature can be particularly useful in emergency situations or during nighttime use when your mobile phone’s light doesn’t quite cut it. 


The GB70 and GBX75 come with all necessary cables, as well as a microfiber bag for storage. This makes it easy to charge them up and stow them away until needed. One think it doesn’t come with, and that applies for both, is a hard case. Yes, you get a microfibre pouch but if you want something more sturdy, we recommend the NOCO EVA case, which will protect the jump starter without really adding much bulk. 

Which one should you get?

On a high level, they are very similar but I would recommend the following to get the most bang for your buck. 

Compact Cars, Sedans, Small SUVs, and those budget-conscious 

For smaller vehicles with engines up to 4 liters, both the GB70 and GBX75 would provide more than enough power. However, considering the price and power requirements, the GB70 would be a more cost-effective choice here.

Midsize SUVs, Trucks, and Vans

For midsize vehicles with engines between 4 to 6 liters, the GB70 would still be a suitable choice. It provides ample power for these types of vehicles and comes with a reasonable price tag. If you want something that might span to the large category in case you upgrade your car in the future, go for the GBX75. It is a safe bet.

Large SUVs, Trucks, and Vans

For larger vehicles with engines between 6 to 8 liters, the GB70 should still work, but the GBX75 would be a much safer bet, especially when weather and temperatures are taken into consideration. Its higher peak amps and enhanced safety features make it a more reliable partner for jump starting larger engines.

Heavy-Duty Trucks, RVs, and Boats

For heavy-duty vehicles and boats with engines up to 8.5 liters for gasoline and 6.5 liters for diesel, the GBX75 would be my recommended choice. Its superior power output and fast recharge time make it ideal for these demanding applications. Alternatively, take a look a some of the larger NOCO jump starters, there are several other solutions for heavy trucks and commercial grade vehicles, such as NOCO GBX155.


As of the time of writing, the GB70 is priced at $199.95, while the GBX75 is priced at $249.95. The price difference is justified by the GBX75’s higher power output, faster charging times, and enhanced safety features.

Both the NOCO GB70 and GBX75 are excellent choices for a portable jump starter. The right choice for you depends on your specific needs and budget. If you need a powerful and reliable jump starter for standard use and well priced, the GB70 would be a great choice. However, if you require a more powerful device with faster charging times and enhanced safety features, the GBX75 would be worth the extra investment.
