Description
With the STANLEY J309 jump starter and power station, you no longer need to dread roadside emergencies when your vehicle won’t start. This compact, portable device delivers jump-starting power with 600 peak amps and 300 instant starting amps. That’s enough power to jump-start your car, truck, SUV, motorcycle, boat, RV, ATV, or tractor; all without the need to use another vehicle for assistance. Simply connect the clamps to the battery, turn on the switch and start your vehicle. The reverse polarity alarm will alert you when there is an improper connection. A high-powered LED light rotates 270 degrees to help you work in the dark. The built-in triple USB port comes in handy to charge your phone and electronic devices. It features an integrated charging cube (a 120V charging adapter) that allows the STANLEY J309 jump starter to be charged using a standard extension cord, so you don't need to keep track of a separate specific charging cable. Extension cord sold separately. For optimal performance, the unit should be charged every 30 days when not in use. Once used, the unit should be charged immediately overnight.

Great product. Perfect for small car (4cyl and small 6cyl). I bought one for my mother. It payed for itself within 1.5 months. She had to use it 3 times because of a loose connection on the battery. My wife has used hers numerous times to keep her phone charged. It keeps a charge for a long time also. I pulled it out of the car after about two months and it was still showing in the green. It also has a reverse polarity indicator and on and off switch. Great for the mother. She just hooks it up, checks the indicator, turns it on, then starts the car(Nissan Sentra). A friend of mine even used it to start his truck quite a few times till he could get it to the shop (Ford F150; unknown engine size). Son uses the light to read at night. Almost didn't get it back. Great for small to mid size cars/trucks/vans. Unit is quite durable also. Unit is not heavy either. My 66 yr old mother uses it and has not problems and feels much better knowing she doesn't have to worry about a dead battery and being stranded.

I am not a mechanic only an engineering student but at my old student job we regularly jump started cars on campus (a few times a night). I've read either very good reviews or reviews where it just did not work. This thing works with my Toyota RAV4 but would I expect it to jump start a full size SUV or a large truck, well I haven't had the chance to try but I figure you would probably need something with higher current output. I've used it a few times when I was silly enough not to remember to make sure my lights were off and when my battery was starting to not hold charge like it used to (before I replaced it). Since there is one with 500A I am assuming if you have a car with higher current demands you should probably get that one or even higher. Another thing to point out is that sometimes if your battery is at that point where it is barely holding on, there's a good chance you need a real car that can sit there and rev up until you do get some current flowing. I've had a few jump starts where I had to rev the truck for 10 minutes. A simple jump start would not have worked especially if it was this jump starter and often times it would even die again when we took off the cables. Before you buy, you should check the specs on whatever you are planning on charging. There were a few times we had to jump start larger vehicles and we almost always had to push on the accelerator to give it more juice so I am assuming you would need something with a higher current output than this basic 300A.

Before I get into how the actual unit performs, I want to clarify that in order to charge this unit, you will need an additional power cord. The charging jack on the back of the unit is relatively small, so it may be difficult to get a cord in there. I had to cut a little bit of plastic covering off of my extension cable in order to charge the unit. Now, having said that, the jump starter is a pretty good product. It's heavy, but at the same time feels relatively cheap. I charged it fully, as the instructions specified, and it was left in the back of my car for a few weeks until it was used to jump an older model VW Jetta. It took a couple of tries, but the unit did as promised. It was used again a day or two later when the car refused to start once again. Overall, not a bad product, I just don't know how long it will really last.

Poor quality - not what I've come to expect from Stanley. Bought it to get my car going after the battery got run down from a light staying on a very long time. At first, it was totally useless because the car's battery was just too flat - it could not begin to jump-start the car, despite the booster being fully charged (on receipt, I plugged in for about 24h before trying to use it, as directed), though when connected, it did provide enough juice to wake the car up somewhat (big deal). Then I discovered that its internal from-wall-AC charger is safe to use to charge a second battery via the jumper clamps, so I used it as a charger for the car's battery (while disconnected from the car of course). Once the booster showed a full charge via its lights, I disconnected it from the car and set it aside, hooked the car back to its battery, and started it up under its own power. Just in case, I took the booster with me, which still read as fully charged at this point. When I got home, I brought it back in the house and plugged it in, as the instructions make it clear that it can be left plugged in indefinitely without harm. Everyone knows how car batteries are. Run one flat even once, or leave it sitting too long while even somewhat low, and it's trash. That said, I had no choice but to keep using it for a while until I could replace it. So, some time later, I used the booster again to try to straight-up jump-start the car, this time with the car's battery still having enough charge to run everything else except the starter (enough to click its relay, that's about it) - so it was just low, not flat. The booster just baaaaarely had enough juice to get the car going. I figure it should be good for a least one more start after that, especially since I was about to take a drive to the store, and run a couple other errands, so I took it with me, STILL showing a full charge. I came back out of the store after an hour or so, and again the car's battery had only enough charge to run everything in the car but the starter -- but I expected that, so out comes the booster. Nope, no good. Despite there clearly being at least some charge in the car's battery, and the booster showing an adequate charge, the two together were not enough to do more than give the engine half a turn. I had to get a real jump start from a friend. The irony of that trip? The very first thing did when I walked in the door was to head for the automotive department to look for a new car battery. No such luck though. Had to go to the local Autozone for a compatible one (due to the need for dual top-post and side-lug connections -- thanks GM! :-P ). While I was there, I had them check the charging system -- it tested good. When I returned home, I plugged the booster back in. It sat that way for perhaps a week, until I had to unplug and move it out of the way to do some routine vacuuming in that room. When I went to plug it back in half an hour later, It no longer showed a full charge - it self-discharged somewhat just sitting on the table, idle. Guess that explains why it didn't restart the car after I got done at the store. Um, guys, the whole point of a jump-starter/booster is to get the engine started when the car's battery is totally flat, to be able to do so at least a couple of times between recharges, and to hold a full charge for weeks on end. This one failed twice, barely worked once, and didn't hold a full charge after being unplugged for just half an hour. Bottom line: don't waste your money. Go to an auto parts store and talk to one of the associates there - get a brand they will stand behind. I'd get a refund on this unit if I could, but it took too long for the failure to become evident (I'm past the return window).

This item was exactly what I was expecting it to be, and after reading the owners manual, I charged this as recommend. This winter I had to use it to jump my car that was parked outside overnight with temperatures below zero. My car battery was completely dead, so I used this product to jump my car which has a V6 engine and a battery more than six years ago old. My car started right up and I was on my way in minutes. I am very happy with this purchase and I am glad I have this option available to me for any future issues of getting my car started in the cold weather.
