Great Product
By GC on Reviewed in the United States on July 1, 2025
The NOCO Boost Plus GB40 is an incredibly handy tool. I love how compact it is—and most importantly, it works! We used it on a dead battery, and it started the car quickly with no issues. Its small size makes it easy to store, and it’s very user-friendly, even if you’re not mechanically inclined. The built-in flashlight is a great bonus, and it can even charge your phone in a pinch. It’s one of those things you hope you never need, but you’ll be so glad to have when you do. Highly recommend for every vehicle!

Good unit but cables are only 23" from clamp tip to clamp tip, not from booster to clamp tip
By consumer on Reviewed in the United States on May 13, 2025
I purchased the NOCO GB40 18 months ago and liked it, except it seemed the clamp cables could be potentially short for some situations. I recently wanted another booster to have in my second car. I almost bought a competitor's product which had longer cables, but then saw that the Amazon ad for the GB40 appeared to show it now had longer cables than the previous one I bought. I assumed they had upgraded the product to address some consumer concerns, and to keep up with the competition. After purchasing a new GB40 unit I found it had the same length cables as my original one. I thought I might have gotten an older model, so contacted the company about sending me the longer replacement cables as shown in their ad. I received a very short reply that the cables are 23" from clamp tip to clamp tip and an apology for the confusion. They sent a picture to show actual length (attached). Comparing the clamp length to the cable length in the picture they sent to the picture in the ad (both pictures attached) it seems the ad picture is not accurate. It shows the cables are about twice as long as the clamps (compared to actual where the cables are a little over one clamp length) and the location of the 23" measurement seems to indicate it is from the GB40 connector to the clamp tip (which is actually about 12"). I pointed out this discrepancy in a reply to the company and suggested they change their ad to use the picture they sent me which clearly shows the actual dimensions, but did not receive any additional response. I think the GB40 has good quality, ease of use, and may have more safety features (such as avoiding problems if the cable clamps accidentally connect together) than the competition. Just be aware that the cable length is shorter than their current advertisement shows. I would give it a 5 star rating, but took away one star for the shorter cables, and another star for the misrepresentation in their advertising photo. The short cable length should be adequate for most uses, especially where there is easy access to both battery terminals, or from the positive battery post to a grounding screw on the car frame.
