The Zeus is likely my best purchase of 2021 - could not be simpler to use, and it eliminates the need to call for road service if your battery’s gone a little light on its charge. So long as one remembers to keep the device itself charged and ready for prime time, it is a very smart use of funds!
I have had mine for several years and it has not failed me. It does need to be maintained. If you use it for other than a car start it is watched enough to be a reminder. Very good for all around use.
Compact and powerful. Just a couple days after receiving this, I got to use it. Twice in the same day I had to jumpstart my father's car until we could get down to get a new car battery. The Zeus is still over 75% charged. It's definitely great to have just in case of a battery issue and without the need for a second vehicle and big jumper cables. You really wouldn't think something so small would be so powerful but it has worked both times I have used it so far. It stays with me in my vehicle and doesn't really take up any space. I drive to remote mountain transmitter sites for a living so this makes me feel better in case I have a dead battery way out in the boonies. Very much worth the money. I think I'll get a second for the work vehicle too.
Haven't had a chance to test the battery starting function so I can't give 5 stars, but everything else seems solid. Cable management is necessary to keep all the cables in the lid but so far so good.
I have used this many many times and helped a lot of people from charging phones to jump starting trucks, cars, boats and even a semi. The charge lasts quite a long time id say 3 months on avg but in the hard of winter. i get about 3 weeks to a months depending. still better then id expect in freezing conditions. My one critique is on the next upgrade is to make this fully waterproof. i have yet to use the zues to power tools but someday I will. with extensive use for the last year or 2. the only thing is that it makes a small whining noise when charging a phone. but i love this thing and incourage my friends to own one
