[This review was collected as part of a promotion.] This is a handy tool to have that is compact and convenient. I love that it's small enough to bring inside and use easily. For how small, it was noisy! But that was expected. We used it to inflate an indoor soccer ball, which is how it will get its most use. However, it is great to have on hand in case of an emergency. I love that it has USB ports to charge electronics and the jumper cables neatly stored just in case.
[This review was collected as part of a promotion.] I love how this is portable and can be stored right in my car. You never know when you will need it in an emergency. I love how I can use it to inflate my tires no matter where I am! No assembly or set up needed. Just charge and use!
[This review was collected as part of a promotion.] This is such a convenient tool to have in your car! This jump starter not only includes an air compressor, but it also has a built in flashlight and offers the ability to charge other devices via USB ports. It's very lightweight, easy to store in your vehicle, and simple to use. It's quiet enough that it doesn't wake my sleeping baby when in use—I will be purchasing and gifting these for all my loved ones!
[This review was collected as part of a promotion.] This machine is amazing! I was able to try some of its features and I loved it. It inflated balls without any problems, the light is excellent—I had a flat tire at night and it illuminated the area perfectly for changing it—and it charges two cell phones simultaneously very well. It charges easily at home. I wasn't able to test the jump-start function for a car with a low battery, but everything else worked perfectly. The only downside is that the compressor is very noisy when inflating.
[This review was collected as part of a promotion.] This is a great product to have on hand. I already used this to air up the tires on my grandkids bike tires. I will be carrying it in my vehicle for my trips out of town. The piece of mind to charge my car if the battery fails is a plus. The idea of having something reliable when traveling is piece of mind also.
[This review was collected as part of a promotion.] This jump starter works great! It is powerful enough to start my car and put air in all my tires. The cables are very thick and high quality. Overall this starter is top tier and very nicely made and easy to use. I like keeping mine in my trunk for emergencies as it is the perfect size and weight for anyone to use easily. It also lasts a very long time on one charge. Overall I love it and recommend it to to others all the time.
[This review was collected as part of a promotion.] I love how this isn't just one tool as a jump starter. It has a lot of features packed in here. It has 3 usb chargers, a flashlight, clamps and cables to jump starter, air compressor, and pressure gauge! Plus it even has an ergonomic handle at the top which makes this tool even easier to use! Plus the price surprised me! Way less than I thought it would be!
[This review was collected as part of a promotion.] The Stanley J7CS7Amp Battery Jump Starter with Air Compressor is a handy thing to have around. It's great & easy for filling tires and other things with air. It has a strong light attached as well as USB ports to charge devices. It charges pretty quick and is light weight enough to carry anywhere. Great product to bring on the go or have around the house in case the power goes out as a little generator for phones etc. It is a little loud but overall many uses.
I like the booster but I did not get a charger. If it was like the 1000w I could just use an extension cord but it uses a 1/4" round 12v plug which means I need an adapter. I can not recommend a product that does not provide a way to charge it and says any 110v cord will work. A minor point is a screw on type air fitting instead of the lever style. Very disappointing.
[This review was collected as part of a promotion.] Very disappointed in this product. There are a few positives — it's lightweight, easy to transport, simple to read, and easy to use. Unfortunately, none of that matters if it can't be relied on when it counts. We had an emergency out of town when a friend's car broke down in the middle of nowhere. We drove five hours to help jump their car and also needed to monitor our own tire since our TPMS is currently broken. When we grabbed this device — fully charged the last time we used it and charged again when we first received it — it was completely dead. It had just been sitting, waiting for a moment like this, and it failed us. Thankfully, we had two other devices with us that actually hold a charge and can recharge on the road. If we hadn't, we would have been in real trouble. I cannot recommend this product to anyone. It's simply not reliable, and if you don't have a backup, you could be stranded.
