How much bigger than SAE? Look pretty similar to me.Anderson connectors are great, I just find them WAY to big and bulky for what I want.
I've been looking into this as well. A nice thing about Anderson is having the wire crimped to the plug; looks like the SAE are soldered?
In the past I always got laptops that ran straight from 12V, but I had no luck this time. Maybe if I hadn't bought one with a high powered video card. I got a step up transformer (12-19V) that is supposedly 95%+ efficient.
