Review: This Item Is A MUST HAVE! - This product truly makes jumper cables obsolete. I purchased this 1 1/2 years ago, charged it, and then stored it in my Honda Accord's trunk. It was not until yesterday, 1 1/2 years later, that I needed it to try to start my car's depleted battery (due the cabin light having been left on overnight). I could see that the NOCO Boost still retained 50% of its charge despite having sat in my trunk for 1 1/2 years. I firmly connected it to my car's battery and immediately my car's dashboard came to life. I waited less than one minute before twisting the ignition key, and on the 2nd attempt (within only seconds of my 1st attempt) - my engine started up. In the past, I have hated to beg strangers to give me a jump, even though I have always carried jumper cables. And AAA has been a nightmare, because whenever have I needed a jump in the past (before buyng the NOCO Boost) - I have had to wait close to 3 hours for AAA to come to me. Then I found out about the NOCO Boost from someone working for AAA who used it to jump an old car of mine. I purchased one immediately. This product is so small, so convenient to use, and mine has proved itself to be so reliable, that I consider it to be a MUST HAVE ! It is sad that a couple reviewers have stated that their product failed to work for them. But with an overall composite star rating of 4.6, clearly almost everyone experiences their product to be reliable. This product should be charged before storing it away. I do not remember whether mine came with a charge.
Review: Extremely Happy - This is a great product. Very compact but still provides what you need from it. I have actually jumped the vehicle more than once before having to charge it. It's a life saver to have in my car and know I won't be stranded. It's nice to be able to solve the problem right away. Does a fantastic job. Got this on sale at a great price.

## Questions & Answers

**Q: Is this capable of starting up a V8? and I don't mean the tomato juice...:)**
A: I it fires my 2020 Lexus 5.7 liter V8 right away with absolutely no problems. I've noticed on my 2016Ford Explorer twin turbo ecoboost if the battery 100% dead sometimes if you wait 1 or 2 minutes then it'll start right up. I also had to watch a you tube video in the beginning because I wasn't do it correctly, after that I've started about 7 other cars with it as well as a diesel truck

**Q: How long does the charge for the jumper last.  dead batteries are few and far in between.  If i were to charge it will it last a year, 2 years?**
A: Mine lasted 6 years, in fairness it did not get charged up periodically. I bought it in 2016, it now won’t take a charge anymore. 
But, I used it 7 or 8 times in those 6 years (Vintage cars) and it saved my butt each time. 
For $100 I feel like that’s a fair trade.  It lasted about as long as I expected. I will probably buy another

**Q: What is the operating temperature range? Can it be safely left in the hot car in the middle of summer (180 degrees or more)?**
A: The people saying this can be stored up to 180°F are wrong. The manual specifically states storage temperature range of 120°F max with a daily avg of 0-77°F. Max operating temp is 120°F, "NEVER operate above this temperature."  There is a warning to never exceed 180°F, this is the temperature at which the battery could explode.  These are NOT meant to be stored in a hot vehicle.  You may get away with it,  or not.

**Q: Will this start a Gel Battery?**
A: I found this on the NOCO faq page....
What types of batteries can Boost jump?
All Boost models (except the GB500 Boost Max) can jump start 12V lead acid batteries only. This includes wet, gel, maintenance free, enhanced flooded battery, and absorbent glass mat batteries. The GB500 Boost Max is capable of jump starting 12V and 24V acid batteries.

### ⭐⭐⭐⭐⭐ Easy, Fast and Reliable
*by J***T on January 7, 2024*

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.
