Noco GB20 vs GB40 – Both Best jump Starters…

Noco GB20 vs GB40: When it comes to jump-starting your car, Noco’s got you covered with the GB20 and GB40 models. In this blog, we’ll break down the differences between these two lifesavers, making your choice a breeze.

Noco GB20 vs GB40 – Quick Comparison Summary

Amazon Popularity

When it comes to popularity, the NOCO Boost Plus GB40 stands out. It’s one of the most highly rated and best-selling jump starters on Amazon. While the GB20 is also well-regarded, the GB40 has a stronger reputation for safety and performance.

Price Comparison

If you’re on a budget, the NOCO GB20 is the more affordable option. The GB40, with its added capabilities and engine compatibility, comes at a higher price point. However, many users find the extra cost justified for the added performance.

Battery Capacity

One major difference lies in battery strength. The GB20 has a 500-amp rating, while the GB40 doubles that with 1000 amps. This means the GB40 can deliver more power to start larger or tougher engines, especially in colder conditions.

Gas Engine Support

While both models can handle gas engines up to 4.0 liters, the GB40 has an edge—it supports engines up to 6.0 liters. This makes the GB40 suitable for a wider range of vehicles, including SUVs and trucks with bigger engines.

Diesel Engine Compatibility

Here’s where the GB40 really pulls ahead. It supports diesel engines up to 3.0 liters, making it versatile for both gas and smaller diesel engines. The GB20, on the other hand, does not support diesel engines at all.

Shared Features

Despite their differences, the GB20 and GB40 share a solid list of impressive features. Both offer up to 20 jump starts per charge, have an internal 24Wh lithium battery, a quick 3-hour charge time at 2 amps, and include USB ports for device charging. Safety features like spark-proof technology, manual override, an on/off safety switch, and a bright 100-lumen LED flashlight are standard. Plus, both come with a one-year limited warranty.

Weight Difference (Correction)

There seems to be an error in weight listing. In reality, the NOCO GB40 weighs approximately 2.4 pounds, not 7.9 ounces (that would be unusually light for a jump starter). The GB20 weighs around 2.7 pounds, making the weight difference between them minimal and not a deciding factor for most users.

Dimensions

Both the GB20 and GB40 have the same compact dimensions—4.61 inches deep, 8.19 inches wide, and 4.21 inches high—making them easy to store in your glove box or emergency kit without taking up much space.
