The NOCO Boost Max GB500+ is a compact and portable 12V and 24V lithium jump starter delivering 6250A of peak starting power to safely jump start dead vehicle batteries in seconds. Designed for commercial and heavy-duty applications, it’s ideal for light trucks (Class 1, Class 2, Class 3), medium-duty vehicles (Class 4, Class 5, Class 6), and heavy-duty rigs (Class 7 and Class 8)—including semi-trucks, buses, RVs, motorhomes, agricultural equipment, construction machinery, mining vehicles, and more. It supports gas and diesel engines up to 45 liters across 6, 8, 12, and 16 cylinders. Engineered with NOCO’s UltraSafe 2.0 Technology, the GB500+ features spark-proof connections, reverse polarity protection, and enhanced thermal efficiency for safe, mistake-free operation on any 12-volt or 24-volt battery. Weighing just 15 pounds, it delivers unmatched starting power in a compact design—replacing oversized jump starters and engineered to start the largest and most demanding engines. It also functions as a portable USB power bank for charging smartphones, tablets, and other essential devices, and recharges in just 5 hours using the included 56W power adapter. A built-in 2,200-lumen LED flashlight includes seven light modes—including SOS and emergency strobe—for added visibility during roadside repairs, emergency response, or low-light work environments. Rated IP65, the GB500+ is sealed against water, dust, and impact, offering rugged durability wherever the job takes you.

I was concerned spending this much money with a new Webstore for the first time. However, their communication was great. They have what I assume is a great automated email system that updated me on every step of the process. They didn't hesitate to ship my purchased product out. It arrived safe and sound. However in the original packaging. That's the only thing I can critique. The product a GB500 has worked perfectly. I had some issues with a GB251+ model that I had ordered from Amazon. I'm still waiting on the return from that. This was a way better investment. Awesome product. Jump starts a 100% dead 12L two stroke like nothing at 24 volts.

I'm a self employed plant fitter who is constantly fighting the battle of overloading my van, the GB500 is perfect with its low weight to power ratio.I spent many hours researching jump packs and although expensive I have found it worth every penny easily starting 24v 6/8 cylinder excavators.
The jump starter has been excellent, wouldn’t be without it now, struggled for so long without this, only criticism is the leads are a little short and find myself extending them with jump leads.
It looks very impressive, but I cannot comment on the GB500 as it will not be used by me. I can however review the service.I was beginning to wonder if I was the only internet trader who doesn't use a webshop as a shield for anonymity. No sooner had I placed the order than they were on the phone to check that the delivery times were acceptable. Times were not critical, but the fact that they cared was nice. Thank you.Clearly a good company with which to do business.
Great response and turn around times
This jump starter is fantastic. It has many features and makes an inherently dangerous task VERY safe. It works well, even for jump starting large equipment. On a 24V system, if the batteries are too low on the machinery you're attempting to jump start, it requires several attempts to allow enough "juice" to flow into the machine's batteries. The unit does get warm internally (didn't notice external heat) but the hot icon was flashing, at which point you have to wait for it to cool down to resume jumping. It does take a while (at least an hour) for it to internally cool down, but this might be quicker in cool/cold weather or if you don't have the unit in the satchel which it ships with.Although haven't tried on a 12V system yet (cars, pickups) I'm certain it will ... MoreThis jump starter is fantastic.

Great product and HIGHLY recommend.
Great product! Works perfect for all types of construction equipment 12 and 24 volt. Hasn't let me down yet!
I received my NOCO battery starter in a short time after placing my order and it arrived in good shape. I have already used it a couple of times and works like a charm. I'm impressed with the quality and ease of use. Customer service answered all my questions before purchasing and was very helpful about using and caring for this product. I look forward to many years of usage.
