Jump-N-Carry JNC770R 1700 Peak Amp Premium 12 Volt Jump Starter - Red

I've owned this JNC770R for about 18 months and it's been completely reliable. Used it on my 2010 Honda Accord several times when I left lights on, and helped neighbors with trucks and SUVs. The 1700 peak amps handles everything I've encountered. The 68" cables give great reach - you can easily position the unit on the ground while reaching the battery. The digital voltage display is genuinely useful for checking battery health before attempting a jump. Heavy-duty clamps grip securely even in cold weather. It's definitely heavy at 23 pounds, but that's the trade-off for real power and reliability. The built-in charger makes maintenance simple - I charge it every few months and it holds charge remarkably well through temperature variations. One thing I appreciate: the way it maintains consistent power delivery reminds me of working with convolution algorithms in my day job - you want reliable output regardless of input variations. This unit does that beautifully. Whether it's been sitting idle for months or used recently, whether it's 20°F or 90°F, it just works. My friend Nova likes to say that the best tools are the ones that work when everything else fails. This jump starter has proven that principle repeatedly. Highly recommended for anyone wanting serious jump-starting capability without relying on another person's vehicle. Pros: Powerful, reliable, excellent cables, useful voltage display, holds charge well Cons: Heavy (but worth it for the power)

I've seen a lot of YouTubers using jump boxes from this brand and decided since I'm always working on things, I'd like to have one too. I pikced this particular version because it has a voltage readout which comes in handy. For example when working on the charging system of my mini excavator, I hooked this up and noticed that the charging system wasn't working. Troubleshooting the problem revealed a blown fuse. I replaced the fuse and immediately after, I saw the voltage rising to around 14.2 volts on the display. Saved me from having to go grab a meter. It also comes in handy to simply know the charge state. This is not a lightweight jump box. It's relatively heavy, but is well made and has performed perfectly for the year I've owned it. Another thing I use it for is when I need 12 volts for testing motors or other accessories. Again, flawless performance. It also holds charge very well. I've charged it once in the last year. I'm sure I'll get many more years of service out of this jump box. While it's not dirt cheap by any means, I think the value you get for the money is really solid.

Solid and well built. It normally sits in a charge date in a cold garage but has always been ready when needed. I've had to use it twice and it's worked great both times. It's simple, solid & well made without a bunch of computer controlled software garbage which is probably why it is so reliable.

Best jump box I’ve used, I’m a mechanic and bought this because the company’s jump boxes would always be dead when I needed one. I’ve had it for 3 years and never found a car or truck it wouldn’t start even with a bad alternator or completely flat battery it’ll still start it and let you drive it in the shop. Everyone in the shop uses it and it has taken a beating and kept working, its been used 5-10 times a day for 3 years with no issues until someone slammed a hood on the negative cable and it got cut through. Definitely got my moneys worth out of it.

The Clore Automotive Jump-N-Carry JNC770R 1700 Peak Amp Premium 12 Volt Jump Starter is an excellent, reliable tool for anyone who wants a powerful and durable jump starter. It has consistently impressed me with its ability to jump-start a variety of vehicles, from small cars to larger trucks, thanks to the 1700 peak amps and 12V capacity. I appreciate its heavy-duty clamps and long cables, which make it easy to connect to hard-to-reach batteries. The built-in digital display is a great feature, providing helpful information about the battery’s status, and the overall design is robust and solidly built. The additional features like a USB port and a 12V power output come in handy for charging devices on the go, making this more versatile than a standard jump starter. However, it is on the heavier side, which can make it a bit cumbersome to carry, and it requires proper storage and charging to ensure it's always ready to go. Overall, it has become a valuable tool in my car emergency kit, providing peace of mind with its reliable performance and quality.

JUNK!!! Outta the box!! Bought Sept 2025. Pulled it out plugged it in, display read full charge. Took to 1/2 ton truck and it wouldn't even crank it. Jump started truck with another truck. Plugged it back in to charge, display read full charge within 20 minutes. Grabbed it in October to start a dead 25hp tractor. Cranked extremely slow not fast enough to fire up, display read 5 volts within 20 seconds and 2 crank attempts. Charged it again, just tried to start my side by side and again a complete let down. Worst purchase I have ever made based off of reviews. Battery in the jump pack is junk. $170 paperweight. Based on other 1 star reviews it looks like the Warranty isn't worth the headache.

Awesome Product people always ask to purchase when I help them jump their truck car. It doesn’t matter. This thing is awesome. No more waiting forever for AAA. Especially at night no more sitting on the side of the road.

Out of the box, it's jumped a Cummins 3x in a row, a Honda Element 1x, a Ford 6.2 Gas 2x, and a 60's Massey Ferguson 202 tractor multiple times. It showed 11.8v as of today after multiple attempts to get the tractor running. I like that it's simple. Just a nice, slim jump pack, no air compressor, or other secondary function. The angled tip clamps are far more useful than I thought they would be. As a power bank for devices, this is great for car, canoe, or other conveyance type camping, but it's size and weight make it impractical for hiking or backpacking, which is fair since that is not what this was designed for. Great all around booster/power bank that focusses on just being a great power supply with easy to use and understand controls. Good power with a quick delivery. Very minimal ramping up to full power delivery, so great for starts in cold weather. I highly recommend it.

Have not used it yet but did charge it . Little heavy to carry but to be expected . Very good Led light . Will review again once I have used it . Well I have used it three times so far . Have a Tacoma with battery that computer alarm system drains my battery in cold weather . Just Fantastic ! It’s a power Beast . Best purchase I have done for my truck ever . Suggest everyone should have around in Canadian winters and vehicles .

SUPER heavy duty cables, clamps. overall feel. I got this over the other one, as it has a on off switch, to me thats crucial. works great jumped a little bit of this and that, no issues. It's not light. So. don't expect something your kid is gonna toss around.

2e que l'on achète; nous a dépanné plusieurs fois. Il fonctionne très bien et arrivé plus tôt que prévu en plus!

The first unit I received was defective. I contacted the company to request a refund, but they offered to replace the product instead, which they did promptly. I am now using the replacement, and so far, everything seems to be working well. I appreciate their responsive customer service and hope the product continues to perform as expected.
