    • Seems Pretty Solid to Me!

The media could not be loaded. The car battery jump starter seems like the real deal. It feels really solid with good weight to it. In other words, it does not feel cheap at all. It comes in a nice protective case. I haven’t had the opportunity to test it on a dead battery yet (I guess that’s a good thing?) but, I definitely feel a lot safer having this in the trunk in case of an emergency. I like how it has a nice large LED screen that shows you how much juice is remaining on it. The starter has other functions in addition to the it’s main use as a car battery jump starter – namely as a portable power bank for your cell phone, tablet, and other electronic devices. At 18,000 mAh, it should be able to charge multiple devices and then some! It also has a flash light function and can also flash for emergencies when you’re trouble. All in all I think it’s well worth the money spent. I’ve seen others go for over $100 and doesn’t look or feel as good as this one. ... show more

Used this 4-5 times so far and works great. Compact, nice case. Now that I finally bought a battery, will have to remember to charge it once in awhile.

The media could not be loaded. An excellent Jump Starter, practical, fast and easy to use, very practical and easy to transport, the instructions are very easy to follow, and in a matter of seconds, you have your vehicle working again, it comes with a package to transport and resistant in case of fall, something that caught my attention are the USB ports to charge cell phones, and its practical screen, where it indicates the remaining percentage. The battery clamps are very resistant, I tried it with my Kia and it started in seconds, the indicators on the clamp indicate the status of the battery. Another aspect that I like is how light it is, very practical and safe, its shape fits very well in the hand, and its led lights, perfect in case of emergency. I love this Jump Starter, I recommend it 100%. ... show more

Really happy with the small size, amount of power and ease of use. Comes with a handy case to store in. I have already used several times since purchase. Only complaint is wishing the jump cords were longer.
