What customers say about "Key Specs"
Clore Automotive JNC4000 12V Jump Starter
  • I've had a JNC4000 since 2010 at a previous job, and it's performed well in all conditions. I had to have one for home. They are well constructed, durable, and with the gel batteries, they can be laid flat.
  • This item holds the charge for a long,long time.This one works for me. I would tell others to buy this model if they were going to buy one.
  • This beauty lets me get right up front where I need to be (standing room only) to deliver the power I need to start my Ford E-450. Cranks every time!
  • It really is powerful and would likely work even on large trucks.
  • Doesn't hold a charge. Low quality lead acid battery is garbage.
  • Well ... the time came that I needed it to start a car in my garage that had been sitting.. I hooked it up and nothing.. It's was a joke... I can't tell you how let down I was that this battery back up needed a back up when it was called into service.... Don't buy it!

  • The charge lasts a RIDICULOUSLY long time. I schedule a recharge every three months and the gauge always reads at or close to 100%.
  • It retains its charge better than anything I've had (I've used and thrown away 4 or 5 different models).
  • It has more capability and power than I really need. Nice to know it's there, though.
  • Not Lithium Ion (LION). A critical plus, as if left in a car and gets very cold, most LION powered batteries lose all power at around 20 degrees F. Lead acid batteries do not (though lose much of their capacity at 0 F).
  • The lead-acid battery cannot leak, and is not unstable. It holds its charge, and can't be over charged.
  • After a year and a couple of months it now refuses to recharge. It still has some charge left in the batter but when I plug it in it doesnt show as its charging, If it would recharge I would give it 5 starts.
  • It does a good job but after a couple of times of charging it seems to not fully chare anymore. I left it plugged in all night and the green light wasn't on and you could see that the charger capacity was not complete. Other than that it works good.

What customers say about "Interfaces"
Clore Automotive JNC4000 12V Jump Starter
  • With the 12V DC plug, you can even plug in your 12v DC adapters for what ever your heart desires.
  • An "internal" charger is built into this unit so you don't have to deal with attaching an external charger like some brands have out there to charge it, and who doesn't own an extension cord?
  • During a bad ice storm power at my house was out for 4 days, the 12 volt plug made it handy to charge phone and tablet. Highly recommend this charger.
  • Awesome! Works well and holds the charge quite well. Great to plug it into the lighter to jump the car versus going under the hood.
Clore Automotive Jump-N-Carry JNC660 1700 Peak Amp 12 Volt Jump Starter
  • 12v to charge small electronics like a cell phone in the woods.
  • Included is a male to male 12 volt plug cord that you can use to charge off a power point. 12 volt charge must be disconnected after full charge, 110 volt can be left on charge indefinitely.
  • The cords and clamps are high quality. Great for dead lawn mower or car. Nice to not have to have long jumper cables.
  • You can charge it from an AC outlet or from cigarette lighter (it comes with an adapter too)
  • Does not include extension cord for recharging unit.
  • My only complaint has been with the A/C power port to plug in your extension cord to charge the unit. The blades actually broke a few years ago and we're no longer able to be used. I remove them to prevent the chance of shorting.
  • The contact grips on clamps are small. Could not attach to my C4 Vette battery. Plastic in handles too thick.

What customers say about "Features"
Clore Automotive JNC4000 12V Jump Starter
  • Powerful jump cable that has proven to be great! I like the convenience of this unit and it may even start a tank.
  • This is a very reliable jump starter and I believe one of the better ones on the market! Just be careful you connect the leads with the proper polarity as it doesn't have a protective device/circuit if you get them on reversed.
  • It is a great companion to take with you on the road and in the garage. I have used it multiple times, and keeps a charge for months!
  • The cables are indeed short and for some cars where the battery is really far away would probably be a problem. For most cars and trucks this would be fine.
  • 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

  • Some may consider this a con since it doesn't have a lot of extra features as a result of being really simple to use.
  • It's durable. The plastic is thick and can take a beating. I accidentally dropped the unit from hood height and it did not crack.
  • All parts are self-contained. Even the white clamp caps are attached so you don't misplace anything.
  • The cables and clamps are very heavy duty and I like the voltmeter. There are two lights for charging and full charged.
  • Wish it had overcharge protection but can't complaint too much... just check voltage often when charging.
  • No on/off switch. Cables are always "hot."
