What it does well
- Spark-proof and reverse polarity protection, which is the feature that matters when you are connecting clamps in the dark at the end of a block and you are tired.
- IP65 housing, so a rainy roadside is not a problem for the unit itself.
- The 400 lumen light is bright enough to actually work by, unlike the token LEDs on cheaper boosters.
- It doubles as a USB power bank, which means it earns its space in the vehicle on days nothing goes wrong.
Where it falls short
- It is five pounds and it is not small. It lives in a cargo area, not a glovebox, and in a delivery vehicle cargo space is the thing you are always short of.
- A jump starter only works if it is charged, and lithium packs self-discharge. A booster that has sat in a hot trunk since last winter is a paperweight. This is the real failure mode, not capacity.
- For a four-cylinder engine, 2000 amps is headroom you will never use. Most drivers are paying $100 for a number rather than for an outcome.
- It restarts an engine. It does not fix a battery that keeps dying, and if you are jump starting more than once, the answer is a battery test rather than a bigger booster.
What owners report
Owner reviews of the GB70 have been consistent for years and are unusually free of drama: it starts vehicles, the clamps are heavy, and the safety interlocks do what they claim. Reviewers repeatedly single out the same detail, which is that the unit refuses to deliver current until it sees a correct connection, and that this makes it usable by people who are not confident around a battery.
The recurring criticism is size and charge retention. Owners describe forgetting about it for a season and finding it flat, and NOCO's own guidance to top it up periodically comes up again and again in reviews as the thing people wish they had taken seriously. A minority report the older micro-USB charging on earlier units as slow; current listings specify USB-C.
Who it suits
- Drivers of larger engines, trucks and vans, where a smaller booster would be borderline in cold weather.
- Anyone whose vehicle has already needed a jump once, which is the best predictor that it will again.
- Drivers who work early morning blocks in cold climates, where cranking current requirements go up exactly when battery capacity goes down.
Who should skip it
- Four-cylinder drivers, who should buy the GB40 and put the savings into a tire inflator, which is the failure you are far more likely to have.
- Drivers who want one box that covers several roadside problems, who are better served by an all-in-one roadside kit.
- Anyone jump starting repeatedly. That is a charging system problem, and a smart charger or a new battery is the actual fix.
Alternatives worth considering
A quarter of the price and a fraction of the weight, with reverse polarity protection and enough current for engines up to 6.0L gas or 3.0L diesel. The NOCO GB40 filled this slot, but its Amazon listing is unavailable. For most delivery drivers this is the correct purchase and the GB70 is the upsell.
Check price on AmazonJumper cables, an air compressor and a first aid kit in one box. It needs a second vehicle to jump from, but it covers three roadside failures instead of one.
Check price on AmazonA quarter of the price at a similar peak rating. The build and the safety engineering are not NOCO's, but if the choice is this or nothing in the trunk, this wins.

NOCO GB70 vs GB40: which should a delivery driver buy?
The GB40 for almost everyone. It handles four and six cylinder engines, costs about half, and fits in a door pocket. Move up to the GB70 only for a V8, a diesel, or genuinely cold winters.
Is a jump starter better than a roadside kit with jumper cables?
A jump starter works alone; cables need a second vehicle and a willing stranger. That is the whole argument, and it is a strong one at 5am in an industrial park. Our roadside kit versus jump starter comparison walks through the cases where the kit still wins.
How often should I recharge a jump starter that I never use?
NOCO advises topping it up periodically rather than leaving it indefinitely, and owner reviews are full of people who learned that the hard way. Put it on the same schedule as some other recurring task so it does not get forgotten.
Will a jump starter fix a battery that keeps going flat?
No. It gets you moving once. A battery that repeatedly dies is either at the end of its life or is not being recharged properly, which is common in delivery work because short trips never fully replace what starting takes out. See the battery management guide.
Does a breakdown during a block affect my standing?
Program terms vary and change, and how a station handles an incomplete block is not something a gear review can tell you. Contact Amazon driver support as soon as you know you cannot finish.
