Jump-N-Carry (KK JNC4000) Jump-N-Carry« 4000 Battery Booster- 12 Volt, 1100 Amp is a little heavy, but it definitely jumps your battery in a pinch!

Same as K&K Jumpstart 990681 Jump N Carry 660 12 Volt Jump Starter but this one has shorter cables and is a few dollars less expensive. I like both of these as they are simple and highly rated. I took this one off my Amazon wish list because I’d rather have the longer jump cables. You may decide otherwise…

for this item you need to provide the cord for it to charge.. ok its only an extention cord.. but they could have added one for about a buck. also the directions say not to let it charge for more that 24 hours i have a cheaper model from sears that you can keep plugged in all the time and it has a smart charge function to protect the unit..

this model just doesnt measure up…. but its ok

For Christmas I wanted to buy my parents an auto battery starter that would work without them having to get out of their car, since they live in the Rocky Mountains where it can stay below freezing. My husband informed me because of their elevation, climate and they drive an SUV they would need something with a lot my amps; so with his help on line we found the jumpstart 4000. Dad was so excited to get it, he opened it before Christmas and had it out during our visit starting quads that had been sitting out in the snow and not running for quite some time. Then wouldn’t you know it our Ford F-250 truck would not start one morning, after a -9 degree F night, when we were taking our one year old to the Urgent care with a 103.7 fever. We grabbed the Jumpstart and the the truck was up and running in minutes. By the time we were headed home from our Rocky Mt.Colorado trip the Jumpstart had been used nearly everyday, even to jump the neighbors snow plow. We were all very impressed with Jumpstart 4000 and knew we made a good purchase.

The unit I bought was purchased from Griot's Garage, which is this item rebranded. It is thin enough (3.5" wide) that I could keep it in my Mazda RX-7 between the seat and storage bins. I used it many times over the last 5 years and it seems to be holding up great. I put it in my finance's car around a year and a half ago. Even she has commented on how often she has used it; not for herself but for coworkers and customers at where she works.

The only criticism I've found is that the cables are a little short at 23" long. Not unusable but I'd like them longer. I just purchased the "660" version of the Jump-N-Carry, the JNC660 for my truck due to the 46" long cables and a larger peak amp rating. I've never had it fail to turn over a vehicle, but I thought it may help with the V8.

BTW I attached two strips of heavy duty velcro (the hook side) on each side of the back of the unit. This prevents the unit from sliding around in her truck. Rating: 4 / 5
