This jumper pack works!!
This product is the best i have bought so far. Have owned 7 different brand names and they all quit working after a year or so. This jumper does what it says it does. I started a tractor that was in our shed for 15 years it sat. No battery in the tractor and i thought let put this little jumper to the test. Well believe it or not this thing did the job. Tractor started without a battery in it. Im buying each one of my kids one of these and im buy 2 more for each of my vehicles and for in the shop. Great product!

Good
Had the older model it worked great. This one a modern looked and it works great 👍. Good quality also, this is the third one I buy. I always end up giving them away to family that needs them and they all work just fine for them
Kamelkim – ★★★★★ (5/5)
It works like it is supposed to!!
We have one that is from the same company but with less amperage. It works great for us at this time in spring and summer. we have used it a number of times helping others out as needed. I wanted a larger capacity for winter use in the mountains while hunting and tracking leading up to. It works great! It will be a welcome addition to our phones, radios, lights, and dead or drained batteries. Just a fact of cars and trucks, sometimes it also needs a little help in the cold.
