A Compact Travel Necessity

[This review was collected as part of a promotion.] The Stanley PPS12CF is a great jump starter and air compressor that everyone should have in their car. The jump starter had a large enough battery to provide multiple jumps to a dead car battery. It provides reverse polarity protection to help those who may put the jumper cables on the wrong terminals. There is also an option to check if the alternator is good or not, which is very helpful for troubleshooting. The air compressor inflates tires without issue and allows you to set a desired PSI and it will automatically stop after it reaches that. I found that it inflated them quickly. With all the functions it is still compact in size and relatively light, so it fit easily in my trunk.

Essential Auto Tool

[This review was collected as part of a promotion.] This feels tough and durable, while also being surrounding lightweight. It performs both jumpstart and inflating functions very well, and the digital display is easy to read. The only thing I’d change is the length of the cables — a few extra inches would make it even better for tight spots. Definitely a must-have for DIYers or anyone with older vehicles.

Best device to keep in your car!

[This review was collected as part of a promotion.] This might just be the ultimate car companion. It’s an all-in-one powerhouse—perfect for emergencies. If your battery dies, it can jump-start your car without needing help from another vehicle. The built-in air compressor makes topping up your tires quick and easy, and the added charging ports keep your other devices powered on the go.

Good

[This review was collected as part of a promotion.] While I haven't had to use the Jump Starter feature, I did use the Air Compressor feature to bring the tire pressure up to the recommended pressure on our new Toyota Camry. All you have to do is set the desired pressure (the default was 50 psi) and it will bring it up to the set point. I would note that the unit is fairly heavy.

Must Have

[This review was collected as part of a promotion.] This Stanley 1200 Peak Amp Power Station has been an absolute lifesaver. Seriously, it's come in clutch more times than I can count. Whether it's jump-starting a dead battery on a cold Seattle morning or providing power for my devices during a weekend camping trip out by the Olympic Peninsula, this thing just works. The peace of mind knowing I have that portable power readily available is worth its weight in gold. It's rugged, reliable, and the multiple outlets make it incredibly versatile. If you're looking for a dependable power station, look no further – this Stanley has earned its spot as an essential piece of gear for me.

Comes in handy when you really need it

[This review was collected as part of a promotion.] This thing came just in time! I mainly got it as a jump starter but it’s nice to have the built in air compressor as well. My father’s 1962 MG-A’s battery died and I had just the right thing for him. Worked like a charm. Only comment is that it is quite heavy, and the usb a and c charging ports are a nice touch but I doubt I’ll ever use them

Good

[This review was collected as part of a promotion.] The Stanley 1200 Peak Amp Jumper is one of those things you don’t realize you need until you do—and then you’re really glad you have it. It’s powerful, reliable, and surprisingly easy to use, even if you’re not particularly handy with cars. The jumper cables feel solid and secure when connected, and the built-in safety features like reverse polarity protection give a lot of peace of mind. I’ve used it multiple times to jump vehicles without a single issue. It starts engines quickly and with no drama. Beyond jumping batteries, the extra features make it a real multitasker. The air compressor is handy for topping off tires, and the USB ports are a lifesaver for charging devices when there’s no other power source around. It’s basically an emergency toolkit in one. It’s a bit on the heavier side, but that’s expected for something this powerful. I’d rather carry a few extra pounds than wait for roadside assistance in bad weather. Highly recommend it for anyone who drives regularly—especially if you want to be self-sufficient in a pinch. It gives you confidence and convenience in one sturdy package.

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.

Most versatile machine to keep in your car

[This review was collected as part of a promotion.] This is probably the best tool you can have in your car, it is an all in one machine. It's great for a pinch if your car battery died, and requires no other car to jump it since the battery has enough power to jump start it. It has an air compressor that can fill up tires very easily, and if you need it, ports to charge up other devices

Best portable jumper and compressor I've tried!

[This review was collected as part of a promotion.] This portable jump starter is literally the best one I've tried yet! It's build quality is superb and it does it's jobs better than i though possible. Not only will this jump your car, but the tire inflator is AUTOMATIC. you just set the psi and it will fill to it and stop! As someone with a couple slow leaks in my tires, it's so nice to easily and quickly fill them up to a safe pressure! Highly highly recommend this product.
