This is my favorite jump starter. I have purchased multiple of these. A newer cars so you need to press the 1000 amp button sometimes to get it to start though depending how dead the battery is. Especially with these new vehicles having such a high power draw.

It works well. If you live where winters are cold and you don't drive every day, you need this. If you live where jump starts take a long time to arrive, having one is a matter of safety. If I'd known about it sooner, I'd have had one sooner.

This thing literally just saved me!
Battery died at the supermarket (it’s 19° out but feels like 0°) and I let it do its thing and made it to the shop to get a replacement battery (which was definitely needed).
If you’re hesitant on purchasing this, just buy it. I’m glad I did! 🥶

My car has been dying every day this week and has been at the mechanic almost everyday as well. They can’t figure out what’s draining the battery so I got this, it jumps my car anywhere between 30 sec to 3 min but that’s still fast. This works amazing and saves so much time having to find someone to jump it and jumper cables and all that I highly recommend. Even if you don’t have issues like I do I would highly recommend having one of these at home and make sure it’s on a full charge so when you need it you have something to use. It’s also helpful when you need to jump your car and don’t have anyone here. One thing I do recommend is not leaving it on the charger after it’s already full charged. I did some research online and that can do more harm than good so as soon as it’s full charge, take it off the charger and it should hold that charge until you need to use it again. :)

Waited to write this review till I had to use it in real life situations when my car died. I've owned now for over 2 years and it's been worth every penny. This has jumped my car 4 times now. Mostly due to cold weather & I dont start car often working from home.

This has successfully jumped my car in 10°F weather and holds it charge easily for over a year without having to recharge sitting in the trunk of my car all year (0°- 110°)

My only very small criticism is wishing it charged via USB-C instead of Micro-USB.

Works great. Used it twice on random cars during this nasty cold break. Battery stays charged in single digit environments and turns over engines every time. Use them at work for vehicles, generators, anything that needs a jump.
Wish they came with a hard case but thats my only complaint. Lives in my vehicle for emergencies.

No cap this product is amazing. I’m in St. Louis is 3° battery completely dead cold start a V8 not even three minutes and it started a regular jump takes about 15 minutes to 20 you will not regret this product small and portable I think this is very essential. I think everybody should have one in their vehicle.

With the recent sub zero temperatures in the Northeast, my car refused to start with a cold battery and engine. It quickly drained the battery trying to turn over. Ordered this and within 2 second the car turned over and began recharging. This is a must for very cold weather without electric engine heaters and no garage area. Will always keep one with me.

I bought this jump box for my daughter to keep in her car for emergencies. Little did I know she would use it getting off late from work in u def a week. It was simple for her to use and she is not mechanically inclined either. Started her car in seconds. It works well, is in a nice bag to keep everything together in your emergency car kit. Charges your devices and has different lightning functions for other tasks.

When I borrowed an old never used car my dad gave me one of these to jump the car, it never failed me. I have a sports car I only use and got tired of jumping it with my other car. I went straight for one of these but wasn’t sure if the 1000A would start a 3.5 v6 as even jumping it with my car would take awhile. When it got delivered, it had 3 bars of battery and started the car up no problem at all. It’s a little expensive compared to some of the cheaper options but with this one I know I can rely on it and won’t be stranded. Well worth the price. It’s the size of my for arm, with simple design and bright led lighting, it’s rugged so you know it could handle abuse. Usb-c charging and provided with cable. I seen someone give a 1 star because of this. It’s 2026 what do you expect? Supports fast charging. Nicely packaged and come’s with a nice little bag to place everything in. Only thing I don’t like is it uses usb outlet to charge things but I didn’t buy this to charge a phone so don’t really care.

I had a Genius booster that started growing out of it's shell, so I became afraid of the battery. The NOCO does a good job jump starting. I tested it on a friend's dead battery. The NOCO comes with a cloth bag. The Genius had a nice case that had a tire inflator, various fittings ( like for soccer balls,) and would hold all the parts. It would be nice if NOCO had a case like that. It didn't take up a lot of room. I have no idea what happened to Genius.

A portable, compact device that uses lithium-ion batteries to supply emergency power and start cars with the battery discharged, being more powerful, lightweight and longer lasting than traditional lead-acid ones, and often includes extra features like LED flashlights and USB ports for charging devices. They are ideal for roadside emergencies, outdoor activities and for extra safety, although for very large vehicles (heavy trucks) greater power is required.

How do they work?

The device's grippers are connected to the positive (+) and negative (-) terminals of the car's battery.

The starter releases a burst of current to start the motor.

The calipers are disconnected once the engine starts.

Key benefits

Portability: They are small and lightweight, fit in the glove box or backpack.

Power: They generate a lot of energy in a small space, starting petrol and diesel engines (depending on capacity).

Extra features: Many bring LED flashlight, SOS mode and USB ports for mobile charging.

Long duration: They keep the load longer when not in use. Buy it as it is an option to use in case of vehicular emergency on the road, I have used it and very satisfied with this article, since in case of emergency it can help you a lot.

I had heard a lot about this portable battery charger, ideal for when your vehicle's battery dies, but I didn't know it worked as well as I had heard. It's practical, lightweight for its function, includes a phone charger, a flashing light, and jumper cables. It arrives carefully packaged and includes a protective case. For me, it works perfectly.

This is an easy to use device! Got the opportunity to use it sooner than I thought. I charged it when I received it and it has been sitting on the shelf for a couple of weeks. It started the car with the dead battery on the first try. I love it!

This is far by the most powerful booster I’ve owned
I’m a mobile mechanic and I charge $20&Up for Boost/Jumpstarts now I’ve literally already made $70 of my money back n ot has a lot of power n on the same 1 charge
