Description

With the STANLEY J509 jump starter and power station, you no longer need to dread roadside emergencies when your vehicle won't start. This compact, portable device delivers serious jump-starting power with 1000 peak amps and 500 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 12V DC outlet and USB port come in handy to charge your phone and electronic devices. It features an integrated charging cube (a 120V charging adapter) that allows the STANLEY J509 jump starter to be charged using a standard household 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. Includes a limited 1 year manufacturer warranty. Power and charge indicator. All Metal Powder Coated Clamps.

    • missing parts bought two of these, one was great the other was not as shwon.
Size: 1000 Peak Amp
The first one I bought for my husband a few years ago was great and still works great, we love it. The second one I bought for my daughter was the mid priced one, the lower price one had 3 USB spots and air pump, the one that was more expensive and I had bought my husband also had the 3 USB PORTS and air pump, the mid range one I got my daughter did not have the 3 USB PORTS or air pump. It was not clearly marked that it didn't have the 3 ports, only one or that it didn't have the air pump. Was very disappointed it that. But other than that would highly recommend the other two. Great price and works great too. ... show more

    • very helpful!
Size: 1000 Peak Amp
I bought this when I knew my car was going to be sitting in a parking lot for over a week (instead of my garage where my car is normally parked and driven daily). When I returned, I didn't want to get stuck if my battery was dead. I charged this device up and kept it in the back of my car while I was gone. When we returned to this lot, my car started right up. However, there was a family close buy who couldn't get their SUV started. I ran over and hooked the device up to their battery and their vehicle started right up after that. The relief on their face said it all. The wife wrote down the info on this device and said she was going to order one immediately. Even though I didn't need to save myself from headaches, it was nice to save another family who needed help. I have placed the device in the back of my wife's car (I need to order another one for car), 2 months later, I checked the status of the charging power and the lights indicated that it was still good and didn't need to be plugged in. I will recommend this device to all of my friends and family. ... show more

    • Not a very good jump pack- very good battery maintainer
Size: 1000 Peak Amp
Doesn’t do very well at all for jumping vehicles with shot batteries- does amazing for holding voltage stable on a vehicle receiving various OBD updates such as pcm or ecm that it’s VITAL to keep good stable voltage. Very convenient to not have to plug every car into the wall to flash it, grab this and my laptop and off we go (most portable jump boxes turn off after 2-3 minutes, this one doesn’t so it’s much safer for long flashes because it won’t turn off sporadically mid flash, looking at you noco and clones) Ps the seller said it wouldn’t work for this use case and don’t buy it. Been a month and use it 5-6 times every day and does wonderfully. 3 month update. Still working great to keep battery voltage at 12.0v while doing car updates. Still will only jump start cars with a weak battery. Bring a 10mm and a wrench with you. Completely unhook the old battery and put this in its place and it’ll start *most* things. ... show more

    • Put simply, it's junk, can't hold much of a charge.
Size: 600 Peak Amp
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). ... show more
