[This review was collected as part of a promotion.] The Stanley 1200 amp jump starter model J5C09D is a handy tool to keep in your vehicle for emergencies. With 1200 peak amps, it's got enough power to start most cars or trucks without breaking a sweat. It also comes with a built-in air compressor, which is handy for topping off tires or inflating other items on the go. There are built-in USB ports to charge your devices as well, and an LED light to help you see at night or in low light spots. I've only had this for a short period of time and so far I haven't had a situation where I need to jump my vehicle, but it's comforting to know that I have the ability in my trunk in the event the need arises. The unit itself is easy to use, with simple controls and a reverse polarity alarm so you know if you've hooked it up wrong. Charging it is straightforward, just needs a plain extension cord (not included). While it isn't the lightest jump starter out there, it's got a sturdy handle and a tough build, which makes it a good fit for keeping around for emergencies. With the convenience and peace of mind it provides, everyone should have one in their vehicle, recommended!

I gave this to my husband as a Christmas gift. He has used it to air up his tires and loves it as most gas station air compressors are broken around us. I read the reviews and told him of the most common complaints he assures me: we have a heavy duty (Orange) extension cord for eventual recharging of the unit (some folks complained about the unit not coming with a charging cord), others complained the unit shuts off - he says it’ll shut off after 10 mins of air compressing as a safety feature. My husband is particular and not shy about divulging if he doesn’t like something - this is a hit with him.

I've used this twice so far to jump start vehicles (I would only ever use the air compressor in an absolute emergency). It took about 8 hours to completely charge when It arrived. I used a 15 foot, 12 gauge extension cord to make the initial charge. I keep it in the trunk of my Honda Ridgeline so that it's not exposed to temperatures as extreme as it would be in the back of an SUV or in the trunk of a car. I normally check it once a month to see if it's lost any of its charge. Normally takes less than 10 minutes to get the charge back to 100% in months I don't use it. It does take about one third of the battery to jump start a V8 Silverado, but significantly less for anything 4 cylinder (somewhere around 20% I'd estimate). Haven't used it to charge cell phones, but I'm sure it would do just fine for that purpose with minimal battery drain.

[This review was collected as part of a promotion.] Thos Stanley jump box is perfect to keep in your car for roadside emergencies!! It super easy to use! Not only will it jump a dead battery, but it will also pump up a tire, it had a super bright light and 3 USB ports if your power went out and u needed to charge tour phone. Its light weight, and user friendly. Super safe to use and its compact ao it doesn't take up alot of space in your trunk!! I highly reccomend this jump box!!

[This review was collected as part of a promotion.] This jumper is powerful. I appreciate all the extra features it comes with. Having a built in air compressor is nice and seems to be powerful enough for an emergency. The display panel is nice. I appreciate the USB ports as well for charging in a pinch. My only criticism is the powered light is loose and wonky.

[This review was collected as part of a promotion.] Our old 1993 Jeep had been sitting for months with a dead battery. We hooked this up and it turned right over and started! It's great that it can also be used as an air compressor, a USB charger and it has a really bright flashlight. This is a great addition to our earthquake emergency kit here in California. Highly recomnend!

[This review was collected as part of a promotion.] I love this Stanley. I have a really old jump starter and power station from a different brand and this blows it out of the water. It's super easy to use, has tons of functions and it's incredibly lightweight. The little LED light was a nice convenient touch. From charging to performance, I have yet to find anything I don't like about it. I will be recycling my old NON Stanley jump starter/power station and using this Stanley going forward! Highly recommend!!!

[This review was collected as part of a promotion.] Amazing product to have on hand for most car emergencies. With two kids in tow, I have peace of mind knowing this thing is with me, in the trunk. It's powerful enough to jumpstart my huge SUV, I don't think the super small power-bank type jump starters can do that, that's all I had before this. You don't need another vehicle to jumpstart your car. There is a helpful light that comes attached with it, which is more useful than you can imagine. It rotates in different directions so you can adjust it wherever you need light. It comes with a tire inflator, you input how much air you want and it does the rest. You can also use it to inflate any sports equipment you need to. I absolutely love the clamp alarm that alerts you if your clamps are clamped the wrong way. Be sure to recharge it or it may not work when you need it the most. Overall, this gives me so much peace knowing it has got my back.

[This review was collected as part of a promotion.] I tried this to air up my tires. It worked well but it really burnt through the battery quickly. I am not sure how reliable or how long I can expect it to keep working. I do like the different features it has and I'll keep trying it to see how I like it.

[This review was collected as part of a promotion.] The Stanley portable power station J5C09D is a solid portable unit that is a must for piece of mind when traveling or in case of a power outage. The Stanley portable power unit has three usb 3.1 ports for charging phones, batteries, and devices. One will need a usb-c adapter. The power unit can also pump tires with the on board 120 psi compressor and includes a nozzle adapter for bike tires. There is an led light to help see in dim lighting. The Stanley J5C09D has a 1200 amp jump starter/cables. All of the cords tuck and wrap nicely for storage. An extension cord for charging the unit itself is not included. I purchased a weatherproof cord to be kept with the charging unit at all times. I recommend keeping the manual with the unit for quick reference on button navigation. There are beeps that occur when the led light and or the usb charger is selected as well as icons. I love this Stanley Portable Power unit and am grateful to have received it as an incentive to leave an honest review on Influenster. I would recommend having this in case you are on a trip or have a power outage.
