Must have for your vehicle
on October 5, 2026
Posted by: DanielR
[This review was collected as part of a promotion.] If you do not have one of these Stanley jump starters in your vehicle I highly suggest you get one today. First and foremost the ease of use, this jump starter will not let you hook up to the wrong terminals, it has excellent starting power( Jump started my 96’ 5.7 L Ford Bronco that had been sitting for 2 months!) The packaging is nice and neat and minimal. No extra wires to fool with. Easy to understand led lights let you know if you are connected properly and turn the key over. Every car should have one of these! The flashlight is extra bright and can setup strobe if you were to change flat! No need to have jumper cables and who wants to flag someone down for a jump in the middle of a parking lot!

Lifesaver for neglected batteries.
on October 4, 2026
Posted by: BenjaminH
[This review was collected as part of a promotion.] While I keep this Stanley jump pack in the car, one of my favorite uses is bringing it out to jump my small engines. These small batteries never seem to last that long an often are dead at the most inopportune time. Whether it's a generator, lawnmower or ATV this gets me up and running even if I've been neglecting a battery for a season. The added bonus of a large battery bank to charge your phone on the go is an big plus. The only thing I wish it had was a Qi wireless charging option.

[This review was collected as part of a promotion.] This jump starter is great. It has a great case for keeping in the back of the trunk. You hope you won’t need it but if you do it’s easy to set up and use. It got my car started immediately

[This review was collected as part of a promotion.] Great product woke up with a dead battery in my work truck, I was able to charge my battery and it powered up instantly. No additional materials needed to finish the job and it was quick and safe.

Awesome, flashlight with jump start that is small
on October 2, 2026
Posted by: MehmoodS
[This review was collected as part of a promotion.] This jumpstart is really light and easy to use. I love the flashlight. It’s almost like the size of a flashlight. It has an awesome carrying case that keeps the charger and jump cables altogether. The jump starter itself is rubberized so if you drop it, it shouldn’t cause too much damage to the ground or to itself. It charges up of a USB type C and can use like a cell phone charger so it’s easy to keep it powered up. It was strong enough to jumpstart my V8 pickup truck.

A must have device in every car
on October 2, 2026
Posted by: SharathS
[This review was collected as part of a promotion.] A portable jump starter that can be charger easily with the supplied adapter and cable and can be kept in the car always since it does not take much time. The clamps are very sturdy and it also has a flashlight that can be useful in darkness. This device needs to be in every car since it is a very essential and useful device. It is a great gift idea to be given to friends and family since you never know when the car battery dies . I used it to charge my bmw and it worked perfectly. It is also very light weight and hence easy to carry along . Great capacity in small package.

Love the power and versatility!
on September 29, 2026
Posted by: MikeC
[This review was collected as part of a promotion.] Was able to jump a 1500 truck and a 4 door sedan so it's power that you need. It did struggle with a bigger truck with a 2 battery setup.
It comes in a durable case that will do a great job of protecting it as it sits in your trunk or tool box. Versatility is also great as this will run DVD 's for your kids or charge your phone with the USB port it has.
The LED flashlight it comes with is surprisingly strong and should light up anything on a dark night.
Overall the conveniences and power of this little battery is a great addition to your emergency kit that every vehicle needs.

Fast charging and easy to use
on September 27, 2026
Posted by: HarryY
[This review was collected as part of a promotion.] Such a portable jump starter that doesn’t take up much space in your car. This jump starter also has an external power bank of USB A and USB C to charge my phone and a flashlight in case I need to jump my car in the middle of night and I could turn this flashlight function on so I can see. Such a small device have such thoughtful extra functions. Another thing that I appreciate are the durable metal clumps, unlike my other jump starter, these clamps are much more sturdy. Lastly it comes with a nice hard box to store everything so it doesn’t get lost.
