Must have for every vehicle

[This review was collected as part of a promotion.] This is a life saving equipment for every car. It combines tire pump with battery charging cables. It’s not too heavy and once battery is charged , it takes a while to run it down . Overall, this is a great vehicle accessory

Must have in every car

[This review was collected as part of a promotion.] I’ve been using the Stanley Power Jumper, and I have to say, it’s a total game-changer. This device is an all-in-one powerhouse that combines a car jump starter, air compressor, light, alternator checker, and USB ports for charging—everything you need in one compact, portable package. The jump starter feature works flawlessly. It easily started my car within seconds, even on a cold morning when my battery was nearly dead. The air compressor is a lifesaver too—it inflated my tires quickly and efficiently, saving me a trip to the gas station. The built-in light is incredibly bright, and I’ve used it several times during power outages and late-night car issues. It’s not only functional but also convenient with its 360-degree swivel, allowing you to direct the light exactly where you need it. The alternator checker is another standout feature. It gives peace of mind by letting you know the health of your car’s electrical system, ensuring you're never caught off guard with a failing alternator. Plus, the inclusion of USB ports allows you to charge your phone or other devices while you’re on the go, which is a fantastic bonus. It’s also quiet!! Overall, the Stanley Power Jumper is an essential tool for anyone who drives regularly. It’s reliable, versatile, and incredibly easy to use. I’ve been impressed with its performance across all functions, and it’s a must-have for anyone looking for a robust, multi-purpose emergency tool. Highly recommended!

Functional but heavy

[This review was collected as part of a promotion.] This is a very handy tool to have , does a lot but is quite large and heavy. I found this to be quite functional especially the air compressor and ability to dial in a specific air pressure though a little on the loud side very helpful. While this does have the ability to jump a large truck battery I feel it could have been improved by replacing the lead acid battery with a lithium battery for weight and size savings that is the reason for the one star deduction. The led light is also very bright and would come in handy if using at night. Overall would be a good investment.

Small all in one convenient must have jump box for

[This review was collected as part of a promotion.] This all in one Jump starter box by Stanley is a must have in your vehicle. I always worried about my spouse needing one of these when she is driving on her own with the kids. Now I know she doesn’t have to ask for help if she need a jump. The performance on this thing is really responsive and surprisingly not noisy at all when using the air compressor setting for inflation purposes.

Maybe I got a dud

[This review was collected as part of a promotion.] I was pretty excited to try this out and honestly it let me down a bit. I will say that the jumpstart function works perfect however the air compressor function leaves a bit to be desired. For starters the gauge reads the pressure wrong and sometimes I have to press the air button multiple times before it actually works. I was also not a fan of the upside down reading buttons as you can see in the pic.

Versatile portable jumper

[This review was collected as part of a promotion.] I really like having a reliable and durable portable jumper with me just incase of an emergency. It has the ability to jump a dead battery, has an air compressor for tires and other inflatable items, and even the ability to charge electronics with the usb ports. This is a perfect rechargeable jumper to take with you everywhere you go.

Great for emergencies!

[This review was collected as part of a promotion.] A powerful and reliable jump starter with 1200 peak amps, ideal for most vehicles. It includes a built-in air compressor, USB/12V charging ports, and an LED light. Slightly bulky, but great for emergencies.

to anyone with a car, get this

[This review was collected as part of a promotion.] Design is so sleek & modern, Handle on front allows it to be easily carried & portable. Charges fast, jumpers on left & right side hidden from view but easily accessible. Digital meter allows you to check battery status, alternator, & lets you set the tire pressure for it to automatically stop once it gets to the set psi. Bright led’s allow you to work during any situation which is extremely convenient. Huge plus, you can charge your devices from the 4 chargers present in this! Not only useful but something everyone should have in their vehicles.

Good quality. Easy to use.

[This review was collected as part of a promotion.] The battery jumper/compressor is very good quality. The unit is very easy to use with simple buttons and layout. The unit is large and heavy so storage in smaller cars might be hard. Inflates tires in a reasonable time. Jumper has good voltage to start up batteries. Great for larger SUV and trucks.

Small Device Multitude of Uses

[This review was collected as part of a promotion.] I typically don't like reviwing stuff without actually putting it to the test. I will say that this all in one really blew me away! The small form size makes it easy to place in your trunk and have it around for emergencies! I used it to pump air in all of my tires as well as used it to Jumpstart my friends car. Overall experience has been nothing short of amazing
