Best gift ever

I keep buying these for myself and end up giving them away. I have friends that are firefighters, fishermen, retired veterans, hunters, and everything in between and these are by far the best and most useful gift I’ve ever given. Will be buying more in the future.

Just Added a Third Zeus to Our Family - And It Won't Be Our Last!

I purchased my first Zeus in November of 2020 to keep in my 2016 Subaru Forester, and had to put it to the test in the summer of 2021 when I had a complete battery failure in 96 degree heat with storms on the way after another vehicle was unable to jumpstart mine back to life. The Zeus got the car running again on the first try without issue so I could safely drive it to my dealership to have the battery replaced. I didn't open that Zeus again until just a few weeks ago - and was amazed to find that it still had a 75% charge! I ended up buying a new 2022 Subaru Ascent earlier this month and immediately ordered another Zeus for my new car, so my original Zeus could stay with my Forester that my college-age son is now driving. After my husband saw the Zeus and checked out the great features, I bought a third one for him to keep in his 2021 Ford F-150. Aside from the incredibly valuable ability to jumpstart a vehicle when we're on our own, the built in flashlight/strobe flash and the ability to keep our phones and other devices charged while away from a power source (or in the event of a power outage or other emergency) is invaluable. We love the product so much that my husband and I plan to purchase more Zeuses for our parents and our other adult kids before the year is out. Many thanks to Uncharted for creating this essential tool!!

Amazing Equipment

I have owned the Zeus for over two and a half years. It has been ultra reliable, and has started vehicles in conditions ranging from below freezing to over 90 degrees. The charge lasts long enough to jump a car many times. I have jumpstarted one vehicle roughly six times and the Zeus still has about 50% charge remaining. I have used it to charge my phone as well. It is very compact and fits easily in my car. This was a great purchase, and I highly recommend the Zeus!!
