I got a new toy today. It’s a battery connector that connects to the deep cell battery with washer connectors. It has a socket for a lighter type car connection with a cap. I also bought a lighter type 5 volt transformer that works in my car or now on the battery. So I have a power supply when PGE shut me down to charge my phone and maybe laptop computer. That’s a huge bonus as I lost power last week. This is useful as off grid and emergency power. It’s cool.
