When it comes to the ultimate in jump starter power packs, the GBX45 by market leader NOCO is as good as it gets for the majority of car drivers. Not only do you get immense power capabilities, but the test car started up as if there had never been a problem.

Build quality is solid. It feels rugged with a rubberized shell and strong clamps. It's rated IP65 for water resistance, so it can handle light rain or dusty garages. The clamps are big and firm, but not overly stiff, which makes connecting to tight battery spots easier. The main thing that stands out about this model is how compact it is compared to how much current it delivers.

The NOCO GBX45 is perfect for anyone with a big SUV and a habit of running the battery dead. Compact enough to stash in your console, powerful enough to jump start cars, SUVs, and ATVs — no waiting on a stranger.

Arguably the be-all and end-all of what a jump starter needs to do, the GBX45 takes all qualities of a typical modern unit and excels at each and every one of them.

This is the Noco GBX45 Boost X. It's a 1250 amp. Now, imagine yourself on a cold winter's morning getting up for work at about 5:50 a.m. I know, I've been there. And imagine you start your car and bump, you got a flat battery. What are you gonna do? Well, this could be the answer. I'm Pete Austin and this is All about cars. Okay. So, I'll just show you that the battery is completely dead. Nothing.

Another major advantage of the Boost X series is ultra-safe technology. This system includes built-in protections such as spark-proof connections, reverse polarity protection, and overcurrent protection. These features help prevent accidental damage if the clamps are connected incorrectly. The jump starter includes heavy-duty jumper clamps that connect directly to the battery terminals.

While it is our top recommendation, there are a couple things we'd like to see improved. We really wish the NOCO Boost Plus GB40 used USB-C in/out, rather than 2.1 amp Micro-USB charging and a 2.1 and USB-A output, but it does come with a car 12V adaptor and USB cable, in case you threw yours away three years ago.

I think the GBX’s li-battery dies quickly over time. Better off with the regular GB150. I’ve been looking these things up for quite some time now.

Issue one, battery doesn't hold charge. Some users say it loses charge just sitting in the glove box. If you need it in an emergency and it's already dead, congratulations, you're stranded with a dead jump starter. Issue two, overheating during use. Push it hard and it can get hot. Like, is this going to melt hot? Not exactly reassuring when you're dealing with electricity and cars.

Encountering a flat car battery is every car enthusiast's nightmare, which makes a portable battery jump starter like the NOCO GBX45 a tempting prospect. This is a popular model for the brand, thanks in part to the fact the GBX45 claims to jumpstart up to 6.5 litre petrol engines and up to 4.0 litre diesels.

So today we're going to go ahead and take a look at this NOCO GBX45 jump starter unit. This was sent out to me by NOCO for me to try out and test in exchange for this review. And I've kind of got the perfect opportunity here behind me. This van, I've got a bad habit of leaving the power inverter on, especially on Fridays for some reason.
