Alright, so update on my previous review: This is an essential for me, especially for camping. I've had to jump my car (2014 town and country) about a dozen times since purchasing this due to a battery fault. This thing is the definition of overkill. Each jump takes somewhere between 10 and 15% of the battery life, and each jump, the van acts like it has a brand new battery, which is perfect. Biggest thing i've jumped so far is a GMC Yukon, which had zero issues. Outside of jumping cars, this is the champion of camping power. Its capable of charging all your mobile devices, rechargeable camping gear, even a laptop, without being the size of a lunchbox, and can recharge anywhere your phone can. Not to mention it can use any accessory your car's cigarette lighter can, and has a light. The only downside is this doesn't have any AC power, but that was never the point. Given the choice between this and a 150w inverter or a jackery (with a built-in inverter) and a car jumper, I'm probably going to pick this every time. What i've noticed since purchasing this: + Perfect for camping: This can charge a phone, tablet, battery fan/light, other power packs, even a USB-C charge capable laptop without a hassle. + Charges on a USB-C phone charger. 16w USB-C won't charge your laptop, but it will charge this, which charges your laptop. + Jumps stuff others won't touch: When "smarter" jumpers detect a bad battery and refuse to jump, this will jump your car, without hassle. +/- Light is designed for local light or signaling, not as a flashlight. Great for keeping people from running into you, not so ideal if you need to see someone at a distance. +/- This will fast-charge phones, but is not compatible with 45w super fast charge 2 some phones are capable of. - Clamps are chunky. Not a big deal, but these do get in the way on certain vehicles where the battery is in an awkward spot. TL;DR at the top: Huge battery, extremely flexible power options (is currently charging the laptop i'm writing this on), easily starts average cars and acts as a massive power bank for whatever you want to do. Just a little bulky but well worth it! Detailed review: About two years ago, i received a NOCO GB40. Supposedly rated to 1000 amps, it time and time again failed to start the 3.6l V6 engine in my Town and Country, my roommate's Buick Rendezvous, really anything I ran across that needed a jump. After two separate incidents in a week where the GB40 failed to start cars under ideal circumstances (full charge, warm engines, no mechanical faults), it was retired, and the GT4000 put in its place. Out of the box, the GT4000 is chunky, at 9x4x2.25", its larger than your average brick. Throw in the accessory kit (jumper leads, USB-C to C and USB C to A cables, PD100 charge cable and a cigarette lighter adapter) and you'll have a fun time getting this into your glovebox. But then again, the GT4000 can probably jump much larger things than your SUV. The packaging is superb, and nothing in the box was really susceptible to shaking in the first place, but I'm fairly confident the box would have kept everything secure regardless. The User Interface is simple, there's 2 buttons, power and boost. Power turns on the device, and when held, turns on a surprisingly bright flash...light? The very bright LED strip is obscured by a milky plastic cover, so it works well as a flood light, but not so much as a long throw flashlight. You can change the mode or turn off by clicking the power button repeatedly. Once on, connect your power leads to the port on the side of the charger, plug in your battery, and click "boost" if the backlit LCD screen doesn't say "Ready". The included leads are plenty long for the majority of batteries out there. I didn't feel like waiting to drain my battery to test this, so I disconnected the battery from my Town and Country and started the 3.6l V6 directly off this. No shock, but there was no hesitation, no difference from using the standard battery, successful start. Obviously this is a bit like using a sledgehammer to hit a nail, but it works! Outside of its duties as a car jumper, the GT4000 has a plethora of charging ports. First is a USB-C, which can deliver PD100 power to charge a USB-C PD compatible laptop, or 18w fast charge for your phone. This is also how you charge your GT4000. Next to this are two USB-A ports, one feeds 5,9,or 12 volts like Samsung's rapid chargers, the other feeds 2.4a at 12v. There is also a port for a cigarette lighter port, so you can run a compact compressor or an inverter. Thanks to its 99.2wh rating, this can easily double as a power pack for camping or long-haul flights on budget carriers, as it will charge most USB-C chargeable laptops once, or run your phone for days at a time. And since it is under 100w, this pack does not have any specific regulations with the TSA outside of needing to be carried in a carry-on bag. (note, you may wish to leave the jumper cables at home if you take this on an airplane, no clue how the TSA will react. I'm not responsible for any TSA-confiscated items or enhanced screening protocols). The LCD display is extremely easy to read, and gives you a lot of data regarding your charger, including charge percent, status, charging rate (in watts, which is very useful for testing the power output of USB ports), and more. If you manage to sufficiently discharge the battery (below 20%), the display will flash, making it very clear to recharge. It sounds like this unit has an internal warmer to keep its battery at an optimal temperature for discharge, i've yet to need to use it, and will update the review once a need arises. I also cannot speak to the longevity of the device, as I haven't had time to cycle it hundreds of times, but I'll update this review as that becomes relevant. Overall, this well exceeds the needs I have for the battery, acting as a car jumper, laptop and phone charger, and USB tester. If you're looking for something you know will start your car whenever and wherever you manage to find yourself, this is it. The only negative is the size, but if you can find a spot in your car to put a couple bricks that you don't need to think about, then it shouldn't be a concern, and is well worth the extra space for the added capabilities over similar, smaller products. P.S. the jumper plug for this are the same as the Noco GP40, but reversed, so you can't use the leads interchangeably.

I bought this back in January 2023 thinking it would be nice to keep in my car for emergencies or on road trips. I like the idea of not having to rely on someone else connecting their battery to mine to jump start. What if I'm alone? What if the other person has an EV? What if I want to help someone else but don't want to risk ruining my battery? This seemed to provide a solution to all those and more potential issues. When I bought it, I charged it to 100%, put it in the back of my car and didn't think much else of it. Then this morning, my car battery was dead and the car wouldn't turn over. I hooked this up to the battery, it showed a charge of 87% (not bad since I haven't charged it for over 7 months) and displayed "ready" on the screen. I turned my key and the car turned over with no problem. Very happy with the purchase and stress free results. Update: when I plugged this item in to re-charge it, charge level read 98%. Not sure why it showed 87% when hooked up to my car battery. I was happy expecting 87% state of charge after sitting for 7 months and jumping the car once. 98% is even better.

This product is the best i have bought so far. Have owned 7 different brand names and they all quit working after a year or so. This jumper does what it says it does. I started a tractor that was in our shed for 15 years it sat. No battery in the tractor and i thought let put this little jumper to the test. Well believe it or not this thing did the job. tractor started without a battery in it. Im buying each one of my kids one of these and im buy 2 more for each of my vehicles and for in the shop. Great product!

We have one that is from the same company but with less amperage. It works great for us at this time in spring and summer. we have used it a number of times helping others out as needed. I wanted a larger capacity for winter use in the mountains while hunting and tracking leading up to. It works great! It will be a welcome addition to our phones, radios, lights, and dead or drained batteries. Just a fact of cars and trucks, sometimes a little help in the cold is needed. Sam
