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.

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.

Well built, Fairly priced,
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.

You will love this thing. Just buy it if you have a regular car.
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.

Worth $99, but "charging" cable is a joke. Good buy for someone with a phone charger.
Well built, high quality. Definitely not a cheapo or a ripoff. Have not used it to jump yet, so I cannot testify to it's usability, but I trust other reviews in this area. Got it for $55 bucks on Black Friday, but if it works as advertised, it's for sure worth the $99 normal price. Carry bag is stylish and sufficient. However It comes with a double ended type C cable. Double ended cable, and no adapter. Meaning, you cannot charge this and use it with what comes with it. Even with an adapter, the cable doesn't have a USB end to plug into it. So, the "charging cable" is essentially worthless and you might as well just use your phone charger, or go buy one. Professional packaging, charges just fine with a phone charger, good quality. Tl;dr: Worth $99 and below, but needs additional equipment to charge. Provided C cable is only useful for using unit as a power bank for your C type phone.

Great for everyday use
I have a Tahoe that I acquired that had been sitting around in a field for 4 years. During that time the mice got in and chewed on the wiring. So the Tahoe has a short that I can't locate that drains the battery every night. I bought this to start it EVERY morning. It works like a charm. I bought it in August and now it's January. In the summer I usually only have to turn the key once and it will go a few days before needing recharging. Now that it's colder I usually need to turn the key twice and it requires charging every day. I've only seen it not work twice. In both cases I think the battery was especially drained (might have been a time where it set for longer than a day). When I hooked it up the lights on the unit didn't even cycle. It didn't do anything. It's only draw back is the lack of instructions that come with it. So how I use it is I hook it up to the battery, turn it on, and the power lights will cycle. Then I hear a click and assume that's when it's ready. Also because it's lithium you shouldn't charge it when the unit is colder than 32 degrees. If you leave it in your vehicle in the winter and it's below freezing you need to let the unit warm up before charging it. You can use it below freezing just don't charge it until it warms up.

Awesome device. Just used it. I bought last year. Needed to charge my car. I charged device last year and it started my car immediately. Getting one for my son. Every women should have this. So easy and no need for another car. You charge it with iPhone charger and if power in house goes out you can charge your phone with it. Love, love, love this!!!!!

Väldigt robust, smidig och förtroendeingivande pryl. Testat 1 gång, bilen startade innan jag ens hunnit säga Engelbert Humperdinck.

Bu işi yapan cihazlar arasında kesinlikle en kalitelisi ,bu cihazlarda mühim olan kullanılan bataryanın kalitesi noco da kaliteli batarya kullanıldığını biliyorum. Defalarca aracımda kullandım ve hala şarjı yüzde yüz

Hoy lo he utilizado por primera vez, después de la compra y primera carga hace cuestión de 2 semanas, funciona de maravilla y arrancar el coche a la primera y en menos de 2-3 segundos batería sin energía nula, ni el centralizado funcionaba. Lo recomiendo tanto como usuario de calle como profesional.

Kann mir nicht vorstellen wie man das negativ bewerten kann, habe ich mir ursprünglich für mein Motorrad für unterwegs gekauft, jedoch erstmals für meinen PKW benutzt. Um gleich Mal ein paar Bewertungen in Frage zu stellen ich fahre einen Cupra 150 PS Diesel und starten hat sofort funktioniert. So einfach zu benutzen, nur an Plus und Minus Pol an der Batterie anklemmen einschalten und Auto starten. Sofort angesprungen und fast nichts an Leistung dabei verloren. Ausschalten anklemmen fertig. Klare Kaufempfehlung, klein, handlich praktisch!!!

Doskonały sprzęt. Mój akumulator był tak rozładowany, że nie mogłem otworzyć drzwi. Jednak z pomocą GB40 odpaliłem za pierwszym razem. Co ciekawe, poziom naładowania urządzenia nie zmienił się. Wszystkie lampki kontrolne, w tym zielona, świeciły się nadal. 👍
