JUMPBOX 600 Car Jump Starter Power Bank: JumpBox V8 Pro 600 12 Volt Battery Charger with USB

We purchased 1 of these units in 2015 for my husband. He moves it back and forth from his truck to his boat and has needed it once or twice without fail. We decided to purchase 2 more, 1 for my truck and one for our 20 year old son traveling back and forth to college. We all feel much safer having this with us. We live in South Florida and had to evaluate for the recent hurricane. I had mine with me. Most of Florida was without power for days after the storm, my cell phone never died. I charged the power bank 1 time before I left home and was able to keep my cell as well as the 3 other people staying with me charged for 5 days. I highly recommend this. Not only that, the company StarkPower is amazing. My husband took his on a recent trip and needed to use his to charge his phone. While packing up he forgot the electric charging cord. I looked on Amazon to see if I could buy a replacement and was not able, I called StarkPower and they sent a replacement cord with no question and no charge.

Not sure how many times it can jump a car on one charge, but it's incredible. It seems to use less and less power the older it gets. It can charge an Iphone about 150%. Super light weight. I leave it in my car at all times for emergencies, and have not experienced any issues. Great product.

This this is great. Car next to me at the gas station battrry died. Jumpbox to the rescue. Started right up !

Its a neat package, jump started a car once, but failed to start the second and third time. Their customer service phone is disconnected and the web site has serious security issues or is down. Beware buying this thing.

Works well

Great kit. Clips are a little hard to attach to batteries. A little more power would be nice if used a lot.

If you need it. You will be glad you have it.

After 4 years and 4 months, the battery swelled and popped one of the covers off. But it still works.
