Customer Ratings & Reviews

I purchased this jump box incase of an emergency and little did I know how soon I would need it. My vehicle has a V8 engine and one morning on the way to work my car made that dreadful “CLICKING” dead battery sound. The Wolfbox 4000A had been in my trunk for weeks in the high heat and still held a 94% charge. The engine turned over like it was nothing on the first attempt and the charge only dropped to 92%. It’s so simple and easy to use. The ability to charge other devices, built in flashlight and a nice protective case makes this an extremely useful tool. I recommend keeping it in your vehicle at all times. "Dare To Go Everywhere"! It's truly a life saver!

GREAT Device to have during these CRAZY Chicago's WINTER Season...I ALREADY Used it 3 times...I will suggest this item to ALL My Family & Friends...Thks...

Compact, powerful, and easy to use. It quickly jump-started my vehicle and the built-in display makes it simple to monitor the battery level. I also like the USB charging feature and the included carrying case. A great emergency tool to keep in your car for peace of mind. Highly recommend.

Seems really well built and strong, bought for emergencies.

I order this item recently and tried it to start my cousin’s car. Is worth having this I always wanted one and finally bought one. Is very easy to use and charge and best of all the size is small perfect for small vehicles and also have a super bright flashlight. Is worth every dollar.

Charges fast and boosts really low batteries. It is easy to use. My neighbor has the exact model and uses it to boost an older Ford diesel truck. I highly recommend this unit.

Works great! Came charged and took less than 2 min to start a dead battery. Good price and compact.

The product works as described!! The size is great and fits in trunk hidden away. The use is simple and easy. I would recommend this product.

This device charged my car instantly without any hesitation. The charger was still at 75% after a full charge from jump starting my car from a dead battery. It's perfect.

Excellent product. Effective and easy to use. Transaction and shipping thru Best Buy was also perfect!

powerfully and simple to use as directed, easily stored in wheel well compartment for future use.

This is a great booster pack. I always keep it in my vehicle for peace of mind in the event of a dead battery. You never know when it will happen, but it will. This pack comes in a rugged case, and you can also use the booster to charge your phone or computer. Quality of this is excellent and you won't be disappointed.

Bought this for my motorcycle as i leave it at work for weeks at a time. However, when i first got this I ended up having to jump start a tractor and it flawlessly started the tractor with little effort. I was very impressed with this and so was my co workers. They even went out and bought themselves one of these starters. Highly recommend this product

Easy to use it's a real life saver you need to get it !

Works great! Easily started my pickup truck. Small easy to store in vehicle.

This is a substantial jump starter. Everyone in my family has one except me. When my battery started running low and harder to start I knew I needed one as well. I purchased this on deal of the day and am so glad I did. I feel more secure knowing I can rescue myself.

Very handy jump start box. Compact and easy to store. Replaces my much more heavy and bulky starter box.

This is a lifesaver! No more tangled and bulky jumper cables. This small device does so much. It has a flashlight, portable usb charger, and a very nice case. It will charge most vehicles. I bought two for my two vehicles. This product is great and highly recommended!
