    Purchased this as cheap jumpstarter failed to work when most needed. The unit is small but well made and has some heft to it. Initially the unit must be charged for approximately 5 hours. The battery clamps are of exceptional quality. There are two bright lights for night time use, usb charger for phones and a cigarette lighter adapter. First time I tried it on my vehicle it worked like a charm

    One of the Top 10 greatest vehicle gadgets I’ve ever purchased for any car or truck I’ve owned.
    A must have especially for roadtrips and or if you have an older battery. Bought this for our 4th Gen Toyota 4Runner. Due to circumstances beyond our control, we had to use this for six months every time we started the truck as the battery we wanted wasn’t available. Kept the NOCO charged properly and it never failed.
    buy one of these for a long road trip. Also, buy one for everyone you care about that drives, especially if they drive at night or when the clocks change and it gets dark earlier in the evening, late afternoon. You won’t have to worry their car battery died and they’re sitting in a parking lot or side of the road.
    It’s also great for an emergency charge of your phone or other mobile device. It also has a nice bright LED lite and LED flasher. However, I’d recommend NOT getting into the habit of using it for your mobile devices as you might just need it one day to jump start your car and might not have recharged it in a whlle. Buy another type of extra battery charge for your mobile and entertainment devices. Use this just for emergencies.
    They have small amp models and larger ones too. With this type of emergency device, bigger is better. Get at least the 1000 amp,
    I’d love to test out the other products NOCO makes. This one is spot on perfect.

    Surprisingly light and small. Charged quickly and was ready to roll. My Jeep Wrangler battery was dead, so I made a video of me trying to jump it. It turns out I needed to leave the GB40 connected to my battery terminals for a minute or so before the engine was ready to turn over.

    I used the GB40 three times in one day (I was intentionally seeing how it would perform) and the charge was down to the 75% mark. After the first jump (needing to keep the battery connected for a minute), the two other jumps were instant. My batter probably just needed more help on the first jump.

    I’m very impressed with how lightweight and well-made the product feels. You may want to ensure the clamps reach your positive and negative/ground posts, since they don’t have a lot of reach between them. They fit a standard battery easily. My wife’s vehicle has the ground post separated from the exposed positive terminal on her battery, but it still reached without issue.

    Note – these come with a USB cable to charge it, but it does NOT come with an AC wall charger. I used an AC USB wall charger ( to charge two of these at once (one for me, one for my wife) – they simultaneously charged to 100% in less than three hours.

    It’s a waste until you need it.I’m NOT kidding as I was writing this review my 2nd noco was delivered. This powerful small jump starter keeps a charge,I haven’t charged it in 2 months and it’s still at 100 but thats not following the instructions. My alternator died on me one time and this thing worked over and over. I scheduled a mechanic to look at it the next day. It works in all kinds of cold weather. I live in Michigan so you know it gets cold!This little thing will save your life. Always be prepared.

    I have had my Noco for over a year and finally had to use it today. My model of car is notorious for being a battery-drainer and I knew there would come a day I needed it. It is Christmas Eve and today was the day that I found a dead battery (of course, on a day I am not about to go get a new battery) but it was exactly zero problem because this Noco had me up and running in mere seconds with an instant start!

    It holds a charge a long, LONG time and I have only freshened up the charge every 4 months or so, whether it needed it or not since I hadn’t used it. Even before I needed it I was impressed enough to give one to each of my adult daughters this Christmas and now I have 100% confidence that if they are ever stuck they can get going immediately! No more stringing jumper cables between stranger’s cars on a dark night, no trying to remember the order of connection between cars, no fear of just getting out there and doing it themselves. Everyone should have one of these in their emergency roadside kit!
