UTRAI 22000mAh Car Jump Starter Power Pack Portable Battery Charger

haven;t used it yet,but it;s keeping a full charge

This product is easy to store and operate. Great value.

I was reluctant to write a review for this product until I had actually used it on one of my own vehicles. Several months after placing it in my car and pretty much forgetting it was there (it is very compact), I needed it, and it worked like a champ! It was extremely simple to use, and it took just one attempt to start the car. It was nearly effortless. Every vehicle should have one of these. No more being stranded, having to wait for help, when your battery dies.

Received unit with 75% charge,took quite awhile for it to charge to 100%.Hooked it up to my fox mustang with totally dead battery and it fired right up . Very pleased ,will update in the future

Small electric vehicles sometimes was forgeted to charge when I go out in a hurry, so it can't be used on the way. So I think it is very necessary to buy this product, which saves me a lot of time.

Dad is going on a long trip next month, so I bought him this car battery portable jump starter for backup. The product has 8L gasoline and 6.5l diesel engine. It has an automatic supercharger power pack.

After waiting for almost 3 hours for a jump start and then having a 19-year old drive up and use this unit to quickly jump start my car, I was impressed. I took a screen shot of it and within a few hours ordered mine. It came within a day or two and I'm charging it now. I'm impressed. I especially like the cigarette lighter type of accessory that I can use to pump up my tires while I'm camping or on the road. And it's so small compared to my big old battery jump starter (that had exactly the same ports) but weighed a ton and took up a lot of room in my car). But when you're camping, or on desolate roads, you need something like this. Hopefully this will last me for a long time.

After the battery in my Acura MDX died for the umteenth time due to current draws, I purchased a Jump Starter Jstar One after watching a tow truck driver jump the battery with a similar device. It arrived yesterday, a marvel of engineering and especially industrial design -- a 9x17 cm. lithium battery and accessory wires and connectors, all in a tres chic zip-up pouch the size of a woman's clutch purse. It is now all charged up, but I have yet to try it in a dead battery situation; that report to follow. To paraphrase Stan Freberg: Who put all those those joules in that little bitty pouch? You know who...

Don't worry about the battery running out in the middle. It is small size, light weight, easy to carry out. It doesn't take much space to put in the car. It's worth buying.

It's very practical. It is quick to start the vehicle and is a backup tool for the car. It can inflate the tires and charge the mobile phone. It's small but really good.
