I have been around powerboats and sailboats my whole life, and I own one of each. My father was more of a powerboat person. He always taught me to start the boat at home before leaving for the ramp, or start it before lowering it off the davits, and that stuck with me.
I accidentally left the battery switch on in my powerboat along with the stereo. The battery ran down, and I could not start the boat before we left for the marina where we keep our sailboat berthed in the Summer, so we put the charger on and left the boat home. We could have jumped it, but then the battery would still need charging, so we left the boat home. On the way, we decided we would look for a starter-pack we could carry for such cases.
We found this:

I bought one, and waited for the chance to use it. I got my chance last week when my “old” powerboat, that I had for sale and sold last week, would not start. I usually start it weekly, but I was preparing for a weeklong vacation, and then I was away for 10 days. Anyway, the battery was just a little weak, so I connected the Autowit. It charged in about 30 seconds and gave me the green light. I hit the start button and turned the key on the boat. The motor was cold, and needed to be choked, but it started right up. I disconnected the device, pretty happy to not have to haul out my charger for a jump start or carry around a starter pack battery.
Now I am seeing that there are “supercapacitor batteries,” which seems a misnomer, but interesting just the same. It seems the battery has a bank of supercapacitors added in order to provide some amps on startup.
I had not seen the topic here, so I thought I would mention it in case others are interested in such a device or have some thoughts on them.
