   This product is so reliable and easy to use.
   This will boost anything or buy a inverter and use it for hours of light or charging cell phones 15 times or more. I liked it so much I bought 2 more.

   Nice unit, though not quite as HD as expected from the CAT name, which is licensed only – CAT does not make this unit.
   The good – cables are 4ga, clamps have braided wire connecting both sides for added current handling, fairly light for the capacity (though it’s still pretty heavy), easy to use.
   The not-so-good – no charging cable included (need to buy JNC350 Charging Cord or similar) or you can’t use it out of the box. Battery is lighter duty than what is included in the JNC 660/770 products which to be fair are much heavier and do cost more.
   Overall a good value compared to most everything else of this capacity level.

   This jump box is amazing. Have had mine for 3 years. As long as you charge it after use and once in a while when not using it… it will boost your vehicle… even multiple vehicles on one charge. I’ve boosted one of my vehicles multiple times with this box. I use the vehicle less than my other vehicle and so occasionally on the coldest days or after long periods of no use I need to boost the battery. It always comes back to life. Even when the battery seems completely dead… wait a few minutes with the jump box on and connected and it will bring the battery back. The CAT CJ3000 is well built/ durable and appears to be insulated from the cold with the rubber/ plastic material it’s made of. Remember like any battery don’t leave it in the cold for long periods if you don’t have to… but I have sometimes and it still works. It’s heavy… but it works really well.

   Wish I read the reviews . I read them after to look for answer I also have only been able to use the unit one good time. It doesn’t come with the cord to charge it . So I bought one and it will not charge . And continues to make a sound as if it has a short in it. It has been kept inside still brand new only used once. And have not been able to use again like similar buyers. Do not buy this product. I just would like to know if anyone has gotten a refund due to thr product not working. Im past the 30days and do not have a extended warranty.

   Got it in two days in new condition. Charged it about 19 hours and then jump started my Honda CRV – 2011 which had a battery that could not even open the door locks, 80% dead I guess. Turning key did NOTHING. It was dead.

   After hooking up the CAT and turning the red button to the jump start position, I turned the key once and held it for about 3 or 4 cranks (2 seconds?) and it started right up solidly!! Just follow the directions exactly as the manual states. I’ll have to see how well it holds the charge. I am recharging it for 24 hours since it was used to start a car. It’s heavy duty and straight-forward. Does not charge the battery – just jump starts the car. Your alternator has to recharge the battery so leave your car on or drive for 15 to 20 minutes. The lights worked but have not tried the outlet which is like a cigarette lighter outlet. You need an extension cord type of electric cord to charge the unit and it is not included.

   Oh its bad! Oh mercy its a terrible product! Doesnt come close to the less expensive ES5000 Booster pac. I thought I would try the cj3000 because of the cat name and boy was that a marketing trick! You guy got me good on this one. Your jump box is garbage.

   Purchased on in 2020 that was great for years. We needed another one, we tried 2 from ezysurvival.com that didn’t work, ezysurvival.com doesn’t do refund on this product so good luck. I was able to get a replacement from the manufacturer, Baccus Global, it is also completely non functioning, so 3 that never accepted a charge from brand new. They changed something in the production over the years, upped the price and it is now a horrible product.

    I ordered a CJ 3000 from you all back in February if I’m not mistaken it would never ever take a charge I read the reviews it’s nothing good said about that battery charger like I said I charged it and I charged it it would never take a charge I try to use it one time but did it not do anything by cranking up a vehicle that one of my friends was stuck in the parking lot I got a warranty on it with the one you wanted that you all give me I got an extended warranty on it for 3 years package that I bought I wished I would already reviews before I bought this product but to me it’s not worth it I seen somewhere on the reviews said the lady that I don’t know maybe she’s a representative for cat CJ 3000 she said it probably was sitting in the warehouse too long and the battery went dead and it would not take a charge but like I say it do not take a charge I had to go out and buy a cord for it cuz someone please respond back to my email so we can take care of this situation I got another product now that I bought a blunt digital display Quick Charge portable power pack I got it charging now but the flashlight do not come on WOW I must be having some kind of look buying products offline and I order everything from ezysurvival.com I know I do not need to be completely charged for the flashlight to come on you can send an email back to me thank you from Travis Carson

    ** 09/21/2021 Update to 1 star review: As to my previous review below, the instructions for this leave a lot to be desired and basically without fail, every time I would see the jumper batter indicator go to yellow, when I would go to recharge it would show as green immediately. I then later tried letting it charge over 24 hours and various other means but ultimately this false charge scenario was a reoccurring theme through the life of this device and now finally, just shy of 5 years it stopped working/won’t take a charge. To make a long and drawn out story short, based on charging issues/user manual contradictions in my use of the device, I cannot recommend, especially for the cost. ————- I have a 74 GMC pickup that I put an Optima Yellow Top in to help with a problem I was (I hope it’s WAS) having with something drawing current and killing the battery (I’ll spare you the details). Anyway I bought this as a “just in case” and sure enough already ended up using it 4 times and all 4 times it brought my baby, a very, very cold blooded baby mind you, right back to life. Now that I should rarely need to use it we will see if it holds up and if my experience changes to a negative I’ll be sure to update this review; based on my experiences thus far I definitely recommend it. The instructions regarding charging could be a little clearer and so far it doesn’t seem multiple uses has changed it from green but I still keep charging it once a month for 24 hours even though it almost immediately goes to green so far. Anyway, I like things to be clear so the instructions could use a little tweaking but at least their understandable and are as basic as you would expect with this type of device.

    Sent to us and doesn’t even work – extremely extremely disappointed and cannot return?! A complete waste of money.
