This is the one.

Easy 5 stars. I've been comparing prices on these gizmos and this is the best price per value given its amperage, compact size, and it comes with a hard case. Battery and jumper are quality with clear charge indicators. I've used this to jump my 4Runner (even at half charge), my wife's Highlander, my son's Rogue (Is leaving interior lights on a hereditary trait?), and I've come to the rescue in a few parking lot emergencies with strangers. It has cranked every time on the first try. Recharges fast with USB-C. Lots of options out there. If you don't need integrated tire compressor, this is the one. Read more

Two thumbs up

This is a must-have for every car! You never know when that battery is going to die on you! I purchased this as a gift for my son-in-law who always seems to have car issues. Hopefully it'll save him in a time of need! Or anyone else for that matter! I've had mine for 2 or 3 years and have had no issues with it at all! It charges really fast and the charge last in storage for quite a while! Get you one so that you will be prepared. It is extremely portable and easy to use in all items fit in the supplied storage bag. And even easier to store in your trunk out of the way! Read more

Quality and price

This is one fantastic little jump it. I've used it on six vehicles and it still didn't need a charge and it did all six vehicles. No issue would highly recommend Read more

Works!

I received the BOOKOO today, and although I was somewhat dismayed that it isn't equipped for wall charging, only USB, it did charge fairly fast, it came half-charged already. I took it out and attempted to jump my car with a dead battery and the car fired right up, even without turning the on button on, the BOOKOO works as advertised so far, I am going to attempt to take it on an airplane to fla and jump a car I have there that has been sitting for six months, I didn't give it a 5-star rating because of the wall charger issue.

Great safety device and backup to ins. roadside service.

Works good on my 2003 Camry which I don’t use very often, thus need a battery jump every now and again. Although I have roadside service on my insurance, don’t need to call them as often and wait etc. Good purchase especially if your out and about and need a jump👍🏻 Read more
