UTRAI Jstar 3 20000mAh Car Jump Starter Power Pack Gas & Diesel Engine

compact and easy to use

these are easy to use, and should be in every car

I had a dead battery and my neighbor brought her's down for me. I never knew these things existed. It worked so well and fast. It was very easy too. I had to have one right away. It's not the same brand and I haven't used it yet but I have no doubt it will work just fine when I do need it. I always do a lot of research and this is why I got this one.

This morning it was very cold and my SUV wouldn't start. I have another brand of car battery starter here that would not start my vehicle, I made sure I had a good connection, it lit up and I thought for sure it would start my car, but not a chance. Thankfully, I had this one in my Christmas gift stockpile, I was going to give this to my daughter for Christmas. So I grabbed it out of my closet and tried it. It started my SUV right up, on the first try.It was easy to use; red on red, black on black. The lights came right on when I made the connection, turned the key and it cranked right up. I was so thankful to have this today.Initially I wrote a review for the other battery jump starter that it was very good. However, it wouldn't start my car this morning. I will have to update my review.If anything changes here, I will update as necessary. For now, I'm giving five stars because it got me to work on time. Just like it was designed to do.This device was also thinner than the other one, I was surprised that it outperformed the other model for that reason. I want to say that both devices were fully charged.

Wow! This thing is awesome for jumping your car. It is so convenient and easy to use! Also, it is so much safer than using jumper cables also you don't need another car to jump you off. It doesn't take up much space and isn't heavy like other jump starters. It can even charge your phone. I love it.

I am so glad that I got this and have it in my trunk now, it just feels like I got additional insurance for my car where I don't have to worry about battery shortage or even to charge my smartphone somewhere for just in case. Both of my cars are a little over 10 years now and the battery went bad a few times over the year. I do change the battery when I need to, but this portable battery jump starter just gives me relief. For now, I use it as an external battery for my smartphone which works great.

The size was perfect for me, worked great!!!

This portable jumper is perfect for motorcycle trips. It fits nicely in my saddle bags or backpack and is very handy if my motorcycle battery is running low. Works well on ATVs also.

This is not only a ports charge for ur car but my husband took it on the boat and was able to charge his phone for the day!!!!

Appears to be professional grade. Length of clamp cables could be a little longer. Light is bright. Nice case provided with product.
