Awesome, that's a super useful tool. Definitely have to get one!There's a handful of people on here who will tell you that they got a message after exactly 2 weeks saying their truck went into "sleep" mode or whatever it's called to conserve the battery. I personally haven't experienced it because there hasn't been more than a week where I haven't driven mine. So I think there is a safety protocol built in to save battery (as there is on most modern vehicles), but those can go wrong or the battery could just be shot beyond computer intervention. For that I always carry a jump-pack with me. Better than jumper cables since it requires no one else to be around to help. And also easy to help others without worrying about maneuvering vehicles into position. I went with a Stanley Fatmax, but just because that was the one at my local Menards at the time, there are plenty of others out there. The other nice thing is a lot of them, including the one I have, also include a small air compressor, charging ports for other devices, and lights. Nice all around device for your emergency kit.
