The NOCO Boost stands out not only for its exceptional performance but also for its incredible ease of use. This portable battery pack is truly dummy-proof, ensuring that even the least tech-savvy individuals can operate it without any trouble. With built-in protection features and automatic start functionality, there's virtually no room for error. This battery pack is incredibly powerful, effortlessly jumpstarting my motorcycle over 15 times on a single charge. What's more impressive is its ability to start my V8 4.0L Land Rover without any issues, providing peace of mind in emergency situations. I've found it incredibly reassuring that I've never experienced any sparks or safety concerns while using the NOCO Boost. Its intuitive design and foolproof operation make it a reliable and safe choice for jumpstarting vehicles or charging devices on the go. Moreover, the inclusion of a USB output port adds an extra layer of convenience, allowing me to charge other devices on the go. The built-in flashlight is a thoughtful addition, proving invaluable during nighttime emergencies or repairs. While the micro USB charging port may feel slightly outdated, it's a minor inconvenience compared to the overall excellence of this product. In the nearly two years since I've owned it, the GENIUS10 has consistently exceeded my expectations, making it a must-have for anyone in need of reliable portable power.

    Bought this a few years back for use with my motorcycle which was giving me some electrical grief and sometimes draining my battery. I've been keeping it charged up in my backpack for the past couple years but didn't end up having to use it until this week when my bike was gonna leave me stranded. It worked like a charm and got me back home.

    It seems to hold its charge very well and I only plugged it in every couple months to top it up but it probably didn't need it. The only downside I have noticed is that in my backpack it can sometimes get bumped and turn its flashlight mode on, which drains the battery. I think that has maybe happened twice and luckily I noticed it before the battery had completely died (at which point the flashlight would turn off and you'd have no idea it was completely dead). Just be careful how you stow it so that you don't accidentally find it drained when you need it most.

    This product is amazing, and I happened to catch it on sale when I found my car dead.

    The day it arrived I charged it up (use a 2.1A charger if you have it, the book shows it only takes ~3 hours to charge and that was my experience - it can take up to 12 hours if you use a 'basic' USB charger - they only include a robust USB cable that can support that amperage, but you need to provide the charger)

    I made a video, but it's pointless to post as the instructions are crystal clear and easy to follow. Red to red, black to black, turn it on. If the lights don't "chase" (flash in sequence), as it didn't for me, the battery is truly dead. Then you hold the safety override button (the red button) for 3 seconds and start your car!!!

    Just make sure you buy one that fits your car, this goes up to 4 or 5L engine I believe - if yours is bigger, buy the bigger model!

    Amazing product, the flashlight has 3 brightness settings plus emergency flashing, and it can also be an emergency phone charger/device charger as it has a regular USB out!

    Sturdy product, amazing packaging, perfect instructions in so many languages - this is how amazing modern consumer goods are!!!

    Saved my skin, because my car wasn't holding a charge even after hours of driving. Used it three times to save my butt that day!

    À peine quelques jours après l'avoir reçu, j'ai pu tester son efficacité sur mon Mazda CX-30 2021. Franchement, je ne regrette pas du tout mon achat. Au premier contact, j'ai pu démarrer mon véhicule. Facile d'utilisation, petit et vraiment léger. C'était la première fois que j'utilisais une telle chose et je n'ai eu aucune difficulté à suivre les instructions. La lumière est merveilleusement bien située. Ce qui permet de voir exactement où je met les câbles. Il tient bien la charge. J'ai pu booster mon véhicule 4x sans aucune difficulté et ce, du premier coup à chaque fois. J'ai dû changer la batterie de mon véhicule parce qu'elle était fini et ne tenait plus la charge. Heureusement que j'avais cette petite machine. Ce qui m'a permis de tenir jusqu'à l'installation de ma nouvelle batterie.

    Efficace, facile et rapide. J'adore ! C'est pourquoi j'ai décidé de donner celui-ci à ma fille pour sa première voiture et que je me suis acheté le GB40 pour moi.

    Est-ce que je recommande ? Certainement ! Il te faut ça dans ta voiture.

    La seule chose qui me dérange, c'est le fait que ça ne vient pas avec un boîtier de rangement solide mais avec une pochette en tissu. Rien pour protéger l'appareil. C'est pourquoi je mets seulement 4 étoiles.

    pro: good packaging, built looks solid and high quality doesn't look cheap (for the price)
    con: tested with a multi meter only shows 0.75v (but my bro said his GB40 also tests same, so i guess it should be ok)

    haven't really tested if it can crank my engine with a dead battery, will update review once i get unfortunate enough to experience a dead battery, hopefully not :D

    Reviewed in the United Kingdom on June 24, 2025
    Verified Purchase
    I’ve had this booster for several years now and it’s saved me a few times. The battery holds charge really well—I can leave it in the car for months and it’s still ready when needed. Even after use, the charge barely drops, though I always top it up just in case after boosting the car. Definitely worth the price, especially since I chose to buy this instead of replacing the car battery. A professional recovery service once told me I needed a new battery after I accidentally left the power on without the engine running. They charged it and quoted £120 for a replacement. Several years later, I still haven’t replaced it and the car has been fine. I’ve only had to use the booster around three times, which isn’t bad considering they wrote off my battery—one that’s already lasted well beyond its expected lifespan.
