Best jump starter ive used. I manage a fleet of 53 trucks and have gone through many jump packs, both expensive and cheap, large and small. I bought one of these over 2 years ago for the fleet, and its still rockin like new. It holds its charge and is able to do multiple jumps on a charge. The best part is how small it is, I have had alternators die or belts fall off, and was able to hook this jumper up to the battery, close the hood, and drive back to the shop. That itself earns 5 stars, saved me a few tow truck bills. Since its small I have no problem handing it to someone and they can keep it in the truck just in case. Finally decided to buy one for myself after testing it out on the fleet for so long. If its on sale less than $100, definitely buy it!

So far so good. Car battery was completely dead and used the manual over charge button and it fired right up. Wish the cable cords were 6” longer. That is why the 4 star review not a 5 star
Great quality.

The NOCO Boost GB40 is a highly recommended addition to any vehicle’s emergency kit. It is a reliable, high-quality, and user-friendly device that performs its primary function—safely jump-starting a vehicle—with exceptional competence. The added utility of the power bank and flashlight makes it an outstanding investment that provides genuine peace of mind. While larger engines may require a step-up model, for the vast majority of drivers, the GB40 is the perfect blend of power, portability, and advanced safety.

This review is for:
NOCO Boost Plus, Model GB40
============================
Short Version:
I love this device and will likely never go without one again. It’s a reliable and easy to use jump-starter, power bank and 7-position flashlight all-in-one, so what’s not to like? I would recommend this NOCO device to anyone who owns a car. Consider it one-payment dead battery insurance with no wait, delays, or co-pay.
==========================
• MY EXPERIENCE:
My car developed a short in the door lock mechanism that drained the battery in less than 24 hours. Between the inept Ford dealership and the excellent local private automotive shop, It took 5 weeks and several visits to trace and repair the short. In the meantime I needed a reliable way to jump-start my car on a nearly daily basis.
After searching Amazon, I purchased this jump starter based on the overwhelmingly positive reviews. And it has really served me well. It was used multiple times between shop visits and has been used multiple times since then. It has been reliable when needed, jump-starting cars with ease. The Li-Ion battery holds a charge for a very long time. After sitting on the shelf for over 6 months it still appeared to hold nearly a full charge. And then only took about an hour to top it up.
I’ve carried jumper cables in my trunk my whole life, but when a jump is needed you can never be certain someone will come along who’s willing and has the time to assist you. This powerful jump-starter eliminates that uncertainty. It’s also very easy to use and makes a great present for friends and family – even those who aren’t very mechanically inclined.
• USEFUL LIFE & RECHARGE FREQUENCY
– From NOCO, when answering a question here on Amazon:
‘The Boost should last several years with regular use and proper storage. To help extend the life of the internal battery, use and recharge at least every couple of months.’
– Not everyone will have a need to use this device as a power bank, so the battery won’t get properly charged and discharged as described. In that case my suggestion is to use the NOCO every month or two to charge your cell phone.
– From NOCO, in the Important Safety Warnings section of the instruction manual:
‘To ensure maximum battery life, avoid charging your product for more than a week at a time, as overcharging may shorten battery life. Over time, an unused product will discharge and must be recharged before use. Disconnect the product from power sources when not in use.’
• FEATURES:
– Powered by a (non-replaceable) 12v 1000A Li-Ion battery.
– Battery Connection Safety — ‘Safely connect to any 12-volt vehicle with our mistake-proof design featuring spark-proof technology and reverse polarity protection’
– Has a Manual Override, which allows the unit to jump start a battery that is discharged below 2v.
– Also serves as a USB connected Power Bank
– Includes a 7-position torch light
• CONNECTIONS:
– 12v Out – The included battery clamps are to be connected here. This is a unique connector so you cannot connect the jumper cables stored in your trunk directly to this device.
– USB In – The included cable, or any USB to micro USB charging cable can be plugged in here in order to charge the NOCO jump-starter battery. The power rating of the charger device will dictate how fast the NOCO will come to a full charge.
– USB Out – Let’s you use the NOCO as a Power Bank (5V, 2.1A), using a standard USB cable.
• RECHARGING –
Time needed to charge the NOCO – The following comes from the User Manual.
Assuming a nearly or fully discharged NOCO GB40:
Charger (source) Rating = Full Recharge Time.
[.5A = 12h], [1A = 6h], [2A = 3h]
• EASY TO USE:
1. Plug the clamps into the NOCO.
2. Connect the clamps to the car battery.
3. Press the NOCO power button to turn it on.
4. Start the car.
5. Press the NOCO power button to turn it off.
6. Disconnect the device from the car battery.

Good capacity. Holds up to harsh environments. Portable but powerful. Will start pickups, cars, diesel tractors and motorcycle. Perfect size to cover wide range if applications.

Ich nutze den NOCO Boost GB40 schon mehrfach bei verschiedenen Autos (Benzin und Diesel) und er funktioniert einwandfrei, wenn man weiß, wie man ihn richtig benutzt.
Viele schlechte Bewertungen kommen eindeutig daher, dass Leute die Bedienungsanleitung ignorieren und dann sagen, das Gerät „funktioniere nicht“. Das ist schlicht falsch.
Damit es klappt, hier eine kurze, einfache Anleitung, die jeder verstehen sollte:
🔋 Kurz-Anleitung für den GB40
1. Rote Klemme an Pluspol (+) der Batterie.
2. Schwarze Klemme an Minuspol (–) oder an einen Massepunkt (Metall am Motorblock).
3. Power-Taste (🔘) drücken → weiße LED leuchtet = Gerät bereit.
4. Wenn nichts reagiert oder die LED blinkt rot, dann:
➜ Boost-Taste (⚠️) 3 Sekunden gedrückt halten, bis die weiße Boost-LED dauerhaft leuchtet.
5. Motor starten.
6. Nach dem Start: Gerät ausschalten, Klemmen in umgekehrter Reihenfolge entfernen.
Ich habe mit dem GB40 schon völlig leere Batterien/Fahrzeug gestartet, sogar nach längerer Standzeit.
Das Gerät ist robust, sicher, und sehr kompakt ideal für unterwegs.
Nur bitte: Nicht einfach blind anklemmen und erwarten, dass es „magisch“ funktioniert.
Wenn man die paar Schritte beachtet, ist der NOCO Boost GB40 wirklich ein Lebensretter bei leerer Batterie!

Brilliant and works perfectly

I’m extremely satisfied with the NOCO Boost Sport. It’s compact, strong, and easy to use. I use it both personally and for my auto parts business, where I often buy salvage vehicles that need to be started. This jump starter has been tested and works perfectly — I’ve started up to 4 vehicles with dead batteries using the boost mode and around 6 vehicles with low charge without any issues.
It’s very practical, charges fast, and feels durable. I would definitely buy it again. Highly recommended for anyone who needs a reliable jump starter for daily or professional use!
Old Enough –
Kullanmadan yazmak istemedim, gerçi sadece 1 kere kullandım ama o kullanım da nitelikli sayılır.
6 aydır çalıştırılmayan 35 yıllık bir arabada, kontağı çevirdiğimde kadranda hiçbir ışığın yanmadığı bir haldeyken cihazı bağladım. Kullanım videosundaki gibi “manuel override” modunu kullandım. 5. ya da 6. denemede motor tık diye çalıştı. Sıcağa ve soğuğa dayanıklı olması nedeniyle bagajdan eksik etmeden kullanılabilecek bir ürün gibi görünüyor. Tek kötü yanı pahalı olması ama ben ilk taksiti bu denemede çıkardım, çekici parasından kurtardım.

I had two old vehicles with dead batteries. This booster started both vehicles right up. I did use the override feature as the batteries were very dead. But YES….I would highly recommend this product. It is also very compact and can easily be carried in a glove box or center console. Comes with a nice storage bag. Just a great quality product that works as advertised. Love this thing.
