A higher-output NOCO pack with useful 12V power and a bright torch, suited to bigger engines than the GB40.
Pros
- High claimed capacity for larger petrol and diesel engines
- Spark-proof and reverse-polarity protection
- USB and 12V outputs for compatible devices
- Bright 400-lumen torch with seven modes
Cons
- Heavy at 2.27kg and relatively bulky
- Some owners find the jump leads too short
- Premium positioning may be excessive for small cars
Overview
The NOCO Boost GB70 is a premium portable jump starter aimed at drivers who need more engine capacity than a compact car-focused pack can offer. It ranks #1 in our list of the top 10 best-selling portable jump starters on Amazon UK, with an overall score of 8.9/10 and our Best overall award. The listing claims it can start engines up to 8.0 litres petrol or 6.0 litres diesel, making it a step up from the smaller NOCO Boost GB40. The TREKURE 5000A is our budget pick, but the GB70 may appeal more if you prioritise NOCO’s safety features and useful 12V power. Its premium positioning and 2.27kg weight make it less suited to drivers who want the smallest possible emergency pack.
Features and specification
The GB70 delivers 2,000A peak current and uses a 12V lithium-ion battery. NOCO claims up to 40 starts per charge, though actual performance will depend on vehicle, battery condition and charge level. Spark-proof and reverse-polarity protection are designed to reduce the risk of incorrect connections; follow the instructions, particularly with a deeply discharged battery.
Beyond jump-starting, it has USB and 12V outputs for compatible devices and accessories such as a phone or tyre inflator. A 400-lumen LED torch has seven modes, including SOS and strobe. The listing also specifies an IP65-rated housing and includes heavy-duty clamps, charging cables and 12V adapters. It measures 32 x 18.8 x 9.4cm, so although it is portable, it takes up more boot space than a pocket-sized booster. The listed three-hour recharge time is via a 12V input; check the supplied instructions for charging options and care.
What owners say
Owner feedback commonly praises the GB70 for getting larger petrol and diesel vehicles going quickly, including when a conventional jump from another vehicle would be inconvenient. Several describe the connections and indicator system as reassuringly straightforward, while others appreciate having a torch and power outputs in one unit. These reports are encouraging, but they are individual experiences rather than a guarantee that it will start every vehicle or rescue a damaged battery.
There are practical drawbacks. One campervan owner found the leads short, making it awkward to reach a suitable earth point while keeping the unit positioned safely. The weight and premium cost may also feel unnecessary if you only need backup for a small petrol car. As with any booster, owners stress keeping it charged and understanding the instructions before an emergency.
Who should buy it
Consider the GB70 if you own a larger petrol vehicle, van, campervan or older diesel and want a capable brand-name booster with safety protections and useful extras. The claimed engine limits give it more headroom than the GB40, while the USB and 12V outputs add some value when travelling or working away from mains power.
For a small car and occasional peace of mind, a lighter, less expensive model may be a better fit. The GB70 is not especially compact, and short leads could complicate some battery layouts. If those compromises suit your vehicle and you are willing to pay for the extra capacity, it is a strong all-round choice among portable jump starters in the UK.
