If you are out on the market looking for a compact, powerful and full of features portable jump starter, then The Genius Boost Plus Series By NOCO is something you should definitely consider. This lithium ion battery is one of the, if not the best small models on today’s market. It has a far smaller footprint to the Clore Automotive Jump-N-Carry and also isn’t lead-acid which has a variety of advantages, which we specifically addressed in our Buyer’s Guide. The model we are reviewing is the smallest one packing “only” 1000 Amps but there are 5 more models from this line of products which range up to the whopping 20 000 amps (enough to jump start a small airplane). The only downside people might find is the price but if you bare with us until the end of this review you will realize how much of a bargain this product is and how good the features justify such a price tag.
Our Verdict: We recommend the GB40 to anyone who is looking for a powerful and yet compact jump starter battery. It is also good for a ton of different features and taking it out with you while camping or going somewhere off-grid will be the best decision you have ever made.
Features That Make It Stand Out
A dependable jump starter is a big deal, but ease of operation will also be essential, especially if you’re not very mechanically inclined. Fortunately, the team at NOCO outdid themselves with the Genius Boost Plus, delivering a compact little jump starter that’s packing some serious power.
Since one of the most spectacular features of this little battery is the amount of power it packs, we will start off with exactly that:
As advertised, there are 1000 amps of electric current at your disposal when buying the GB40. This is both starting and peak numbers which is a good thing since you won’t have to wait for the electricity to peak before the engine can be cranked. This amount of power is sufficient for all petrol engines and most diesel ones up to around 3 liters, providing all of those have 12V lead-acid batteries.
Since it’s a small device, it can head up quite quickly and it will need a minute or two to dissipate that heat. This means that between cranks you will have to give it some time to rest, in case you want to try once again. When cranking, on average you will get around 15-20 charges before the battery is completely dry.
Safety Features And Maintenance
NOCO has put certain technologies in charge of your safety here. One of those is a patented spark-proof mechanism which will keep the jump starter and your car’s battery spark-free during the cranking process. On top of that, there is a reverse polarity detection which warms you in cases when you connect the cables in a wrong way.
There are indicators on top of the battery which show you the charge level of the unit and warn you in cases when something isn’t done properly. Those make the GB40 a breeze to operate at dark conditions and we find it especially useful for night camping when you need a battery to charge your mobile devices. Speaking of mobile devices, the capacity on this battery allows for around 4-6 charges on a typical modern day smartphone.
In terms of maintenance, you will have to charge it at least once a few months if you aren’t using it. If the weather gets super hot or cold, you will have to do this at least once per month to keep the battery healthy. Even though lithium ion batteries are generally far more durable than lead-acid, they still lose charge over time but slower. They are also generally more heat and cold resistant making them a good choice for people living in tropical or extreme cold regions.
Once again, this model is the smallest from the Genius Boost line and it was created with portability in mind. It is slightly heavier than most batteries in this category, weighing at around 2.4 pounds. The size is small enough to fit basically anywhere and we found out that it fits perfectly in most glove boxes. Backpackers prefer lighter models than the GB40 since there are batteries with similar power at around 1 pound. Furthermore, this thing costs twice as some other batteries of the same caliber, making it a not-so-ideal choice for most people. The truth is that those other models lack the safety features and the smart charging/discharging options the Genius Boost line has.
Besides the USB charging ports you get here (USB In/Out) you also get a 7-mode LED flashlight. To be honest, we’ve never seen such a sophisticated flashlight in a car battery jump starter before. These models also include an SOS mode and an emergency strobe. It is a nice little feature which NOCO didn’t have to include but they did and make their product so much more awesome.
The Genius Boost Plus gives us faith that the cliché “you get what you pay for” isn’t always true. Powerful and easy to use, this model easily outperforms higher priced models.
The manufacturer makes many claims regarding performance, but can this jump starter really deliver?
The biggest claim NOCO makes involves how many vehicles this model can charge per charge up. According to the manufacturer the jump starter can charge twenty cars on a single charge. When put to the test this jump starter can easily charge twice as many vehicles without breaking a sweat.
Like other jump starters on the market, this model will need to be recharged between uses in order to avoid a dead jump. However, unlike competing models that need to be charged once or twice a month, this model only needs to be charged every few months. This is just another reason this jump starter so scored well.
We only came across a couple of issues with the jump starter’s design. Both are minor and not exactly a deal breaker, but they’re still worth mentioning. First, the light button can get switched on accidentally, very easily. If left on for several hours you’ll be left with a dead jump starter. Because of this design oversight you’ll need to pay special attention to how you store the jump starter and make sure it’s well-secured in your trunk in order to prevent the light from getting switched on.
Another design flaw that’s worth a mention is the length of the cables, which are much shorter compared to competing models. Obviously, the manufacturer made the cables shorter in order to make the jump starter more compact. However, this can hinder use at times.
Is it Worth a Second Look?
There’s plenty to love about this NOCO model. Despite the shorter length of the cables, they’re made out of heavy-duty material and are incredibly flexible. The jump starter runs on a lithium-ion battery, which is known to hold a much better charge compared to lead acid batteries. The higher power rating and the model’s ability to charge more cars compared to the competition should give potential buyers every reason to hit that buy now button.
Easy to use, reasonably priced, and equipped with some nice extras that make jump starting a vehicle simple and fast, this is a model we’d highly recommend to pros and car owners.
