Serious power to jump nearly any type of vehicle

Serious Power for the Toughest Starting Tasks

It's All About the Battery...

Jump-N-Carry is all about power--the power to start what doesn't want to be started. Every aspect of a Jump-N-Carry unit is tailored to support the goal of delivering as much starting power as possible to a disabled vehicle, starting with its Clore PROFORMER battery. The proprietary Clore PROFORMER batteries are designed for maximum power density and durability, which results in exceptional cranking power, extended cranking duration, and a long service life.

... Combined with the Power Path Components

But it doesn't end there. All other components of the power path are designed to support the goal of getting the jump starter's power to the disabled vehicle. This includes the heavy-duty cable leads mated to the battery's output and full size clamps that penetrate corrosion on the vehicle's battery for a good electrical connection.

Don't Let It's Small Stature Fool You

Heavyweight Jump Starting in a Lightweight Package

It's easy to be fooled by the small stature of the JNC300XL. After all, it weighs just 9 pounds. Don't let that make you think it isn't up to your toughest starting tasks. Its Clore PROFORMER battery provides as much or more power than much larger jump starting batteries. This enables the JNC300XL to jump start virtually any passenger vehicle, from cars and SUVs to pickups and minivans, not to mention motorcycles, riding mowers, small boats, ATVs, and personal watercraft.

Repair Service Coupon

Every JNC300XL includes a Repair Service Coupon that allows for a fixed cost, one-time repair of the unit after the 1-Year Limited Warranty period has expired. The coupon can be used for any repair, irrespective of the cause of damage to the unit. This provides great peace of mind that if your unit is damaged in any way, you can get it repaired for a fixed price.

5.0 out of 5 stars Nice, Compact, Works November 12, 2009

By H. Stewart

We purchased the JNC300XL about a year ago to power a camera system we were developing for a truck. We needed 12Vdc vehicle power while in the lab and in the field for testing off the vehicle. It charges quickly, holds a charge for months and is light and compact. Last summer my wife called to say she was first in a left turn lane on a busy expressway and her car stalled and would not start. I grabbed to JNC300XL where it had set for months without a charge and off I went. I connected it to her battery and it provided plenty of power to turn over her fair sized V6 engine and start the car. The nice thing is it was a quick hook up. I wasn't in the middle of a busy road trying to get my car close enough to her car to string a couple of jumper cables. It is great for powering gadgets that normally plug into a cigarette lighter for power. You unplug the "flashlight" on the front of the unit to access the cigarette lighter plug. As with all batteries it should be charged every several months to keep the batteries from becoming un-chargeable. Since it is a sealed spill proof lead-acid battery like a car battery it does not have a memory nor will it be damaged by being topped off once in a while. It will die if left discharged for a long period. The manual can be found at [...]

5.0 out of 5 stars Jum N Carry Jump starter December 24, 2009

I already had a JNC 660 for my truck and wanted to put smaller units in each of our cars. I bought 3 of these, then 2 more for Christmas gifts. They are easy to use and much more dependable than the cheap imports with lots of whistles and bells.... I prefer the larger unit for my dodge 1500 with a V-8 (I've jumped it 5 or 6 times between charges without a problem... electrical trouble...) This smaller unit is great for our Toyota 4 cylinder cars and Chrysler Concorde with a 3.5 6 cylinder. These beat the heck out of jumper cables, and my daughter and wife don't have to ask strangers for help... or wait for AAA.

3.0 out of 5 stars Got to work...after some trying July 14, 2011

Changing my 1-star review to 3-stars. I purchased this unit but it wouldn't start my 1997 Land Rover Discovery V8 -- at least not by following the standard directions. I spent over an hour with it over two days trying to start the car but it simply wouldn't turn over. This said, I was able to start the car using jumper cables connected to another vehicle, and AAA was able to start the V8 with a similar but larger portable unit. I finally called Clore Automotive Technical Support at [phone]. First off, they were super nice. They suggested that the JNC300XL may or may not work with a V8 truck, that a larger unit might be required, especially if the truck battery were completely dead. AAA had been out several days earlier, tested the Land Rover battery, so I knew it was OK, it was just low.

The Clore technician asked how I was connecting the unit. I said I followed the instructions, connecting the red lead to the red battery terminal and connecting the black lead to a non-moving metal engine part. He said, "There's your problem. You should connect both cables directly to the battery. They tell you not to do this in the directions, to avoid sparks, but it's what you need to do." I tried it and the Land Rover started instantly. So, it works and looks like this unit can save me in a pinch. I will keep it in my car from now on. I only wish the instructions included this extra bit of information, or what to do if the car fails to start following the standard instructions. If you have any issues, I'd recommend calling Clore Support.
