E16

My car’s battery was dead, a neighbor came over with this device and jumped my car. I immediately went and ordered the same exact one as I had seen it worked for my car & he highly recommended it, when I received it, I read the easy short directions and started by familiarizing myself with it, although my neighbor showed me how to use it, It has a LED bright flashlight that also turns into a SOS, it comes with different cables to initially charge it, it charged in less than 4 hrs. the light will turn green when it is fully charged, it will even charge your cell phone, it is very easy to use, it comes in a carrying case. Thankyou for making this product, I can now drive with peace of mind.

I did not know such a product existed until I came out of a music festival and my car battery was dead. I found a policeman who helped me start my car using your device. (A kind man tried to help me start my car with jumper cables but the battery was to far gone and wouldn't respond.) When the officer hooked up the Jumtop to my battery it fired right right up! I was so impressed with the product I ordered it from Amazon the next day! I am grateful I had a dead battery so that i could find out about your amazing product!

I purchased this unit 5 years ago. I have used it a few times. I haven't used it for a year, but when I went to use it today, I found the unit had essentially, blown itself up. The battery had expanded about 30% is size, forcing the case open. Obviously, this unit is absolute toast and failed to a defective battery.

The product works very well. Power wise it is hard to tell if it is overrated on amperage but it did start my 3.8 V6 just fine with a completely dead battery. I feel confident it would start something much large but it may be down on some power compared to a brand such as noco.I was hoping the red on the outside was rubber to help with drops but the case is extremely nice and protects it very well. I wouldn't mind having another case to store other things in such as a amp meter.The instructions are not very clear, the pictures on here explain more that the instructions do but it is easy to figure out. The clamps are much better quality than other brands but they are a little short. Wires themselves are approx 6" on negative, 8" on positive. This does help with storage and for as much as you use it, it is not a problem.Bottom line, it doesn't have many bells and whistles but it will do the job for 90% of people and will have a higher amp to start larger vehicles. That is the ultimate point of the product, not how many devices you can recharge.

I just received this unit and have not used it to jumpstart a vehicle.I read through the manual, was a little confused on how to charge it, but figured it out. I like that it is multifunctional. We will take it with us when we go boating and camping. Super cool that it can charge usb devices.So far it looks awesome. I will update this review later after we have actually used it. Seems like a good bang for the buck.

wow, this product saved me so much hassle!! my car battery died and I used this to jump my own car and get to the automotive store. I've been promoting these to all my friends - my daughter is getting one (she has jumper cables but this is so much better - you don't need another car to jump you!) Easy to use, just remember to charge every month or so

I was searching for a 1500A+ jumper battery. Every other ones are $99+ and this one is only $60 after the $10 off coupon, so I gave it a try. It came with a really nice package, charged it and tried it on my car. It works! Not sure how durable it is yet. Will come back if there's any update. I think for this price, it is a great deal.PROS: good package with a nice case, great price, works as advertised.CONS: can't tell if the battery is charged to full from the indicator.

This jump starter never worked at all. I opened the package was real happy on how it looked and then I slowly found out that the item was jump. It wouldn't show any signs that it was working not even one. It was like I just bought a BRICK. That it I bought a really good looking BRICK. It going back, a huge waste of my time and how I have to find a UPS drop off location because it has a li on battery in it and USPS does not accept them. One company I will never buy from is JUMTOP, From now on I'm calling them... JUNKTOP
