I have used this to quick charge my Yeti 1400, and man does it work! I did have to plug into the front of my Yeti instead of into the MPPT. I saw other people with this issue, so I'm not sure if this is something to do with the MPPT that isn't disclosed, or someone isn't playing nice.
ProsQuick charge when you need it.
ConsDoes cause the Yeti to turn the fans on, so the area will be louder.
Best UsesA backup way of charging. If you can get to an area with power, you can charge your Yeti fast.
