Clore Automotive Jump-N-Carry JNCAIR 1700 Peak Amp Jump Starter with Air Compressor

No computerized safety features make this the ultimate booster pack.Started a completely flat battery in a car that sat for more than a yearHad a vehicle whose lights were left on all night in -10 degree weather. It was a large engine filled with 20W50 oil. So cold outside the car didn’t want to turn over and definitely wasn’t about to start. This booster pack sat connected to the battery for about 15-20 minutes and it started. Incredible!Connected to the main (trunk) battery under the spare tire in a BMW X5 when the alternator failed. Between the inadequate to start+barely sufficient to keep the car running main 12 volt battery plus this JNC Air clipped to the main battery in parallel, we were able to drive the vehicle for more than an hour with zero further issues until we got the vehicle to the shop, avoiding the need for a tow. It was stressful as we watched the dash voltmeter drop (instrument cluster hidden features that can be unlocked), but we made it. At the time, this particular JNC unit was seven years old, definitely not well maintained (there were a couple of years when we didn’t use it and completely forgot to charge it, while it sat on the floor in a basement) yet it always worked flawlessly and exceeded all expectations.Couple months later a similar scenario with a friend’s V8 Lexus LX. Alternator failed, main battery was completed depleted and couldn’t start the vehicle. Clipped the JNC Air to the main battery under the hood, started the car, left the JNC unit in there and jammed it in place by lowering the hood on the JNC unit; drove to the repair shop (only a few miles away this time) without anything more than the coiled air hose becoming kinked from the weight of the hood.We have helped many neighbors and strangers with this jump starter. This has started numerous vehicles without charging for months. It’s simply that good.This unit has saved us an incredible amount of time, made us countless friends, inflated numerous tires, and tested various electronics (using it as a 12 volt power supply). We felt we were pushing our luck with the JNC, being eight years old and quite abused, so we bought a new one of these and passed this to our tow company friend, who, after another two years, continues to use it on his AAA calls.Bonus: Recharges with a standard extension cord (120 VAC outlet). No need to use external transformers or keep track of special chargers.Other considerations worth mentioning:-This is a professional grade unit - it is large and heavy. Not something most will want to drive around with in their trunks at all times.-The air compressor works wonderfully however the attached/supplied hose and chuck aren’t the best.-The replacement certificate requires one to pay to mail the old unit in plus pay a $150 fee and you get a repaired or refurbished unit back. In other words, the certificate is financially pointless. Better to purchase a new replacement unit with all new parts within.

I own the 660 without the air pump and matched to a viar compressor with direct battery attachment's and this one too . I put one in both cars I drive plus the boat . I have found them to be very dependable and easy to use . It is hard to find these with overcharge protection ( only with 110 not 12 v ) . You can leave this plugged in all the time . I keep them in the car trunks and use the reminder service to tell me when to charge it every 90 days . It takes a long time to bring up to charge but is worth the effort .You can do anything with this but of course you must spend a few bucks . I have a small 300 watt inverter that I can run a little 4 watt Led lamp for a few nights from and a I can use a usb 12v adapter so I can charge my power base , phones and kindle also . Comes in very handy when camping I will actually take a couple of them with me then and whenever I can charge ( driving , or using the generator / 110 if available ) Works great with a 12 volt adapter to inflators for rafts or tubing . I saw a couple of complaints but I have never had a failure yet and one is two years old . Always still useable after 90 days when I top off the charge again . In fact should be something I do soon . This is part of my automotive safety / survival kit . I also have a electric impact and jack . I love this for filling tires it does a great job much better then any pumps but a viar direct to battery . You get what you pay for and each one comes with a coupon for a huge discount on a second battery ..don't misplace or loose it .They suggest you keep the box and store it in there since the cables are always live or hot . I have tried several others and they all failed me within a few years . These have never failed for me or my friends . They will start a few cars in -20 degree weather before needing to be charged overnight or longer . Ps I still like this though they now have some Lithium and Lion battery ones this is a heavy AGM . The price is the same but the lithium and lion starting based deivices are half the size and weight if that . Worth considering for some though this is proven .Remember the 110 volt recharging you do with your extension chord has overcharge protection in the circuit but when you use the 12 volt car charger it does not and that charges fast you must read up on it at the company website or you may damage your charger when using it . I can't wait until these use Lipo batteries and have protection for both charging methods . These are the best jump packs made for the public pure and simple do not be afraid of them but they are not cheap . Both of mine are still working fine and barely need a charge every 90 days if not used . I have forgotten and gone all winter and they still start at least one car . Both of mine are large v-8's .
