Dakota Lithium Power Box 10... Thoughts?

Not stoked on the build quality of the Power Box, and definitely not stoked on their customer service. Long story short, I'm back to square one and will likely just build my own box...

I built this NWKA design 3 years ago, still going strong, I use a dakota lithium battery in it now too.  I use it more often off the water than on actually.  Neat little charging station for all the modern gadget electronic devices.  I have the parts to make is solar, haven't built that yet but plan to sometime this week or next.  The panel and regulator are sitting on my kitchen table, taunting me, daring me to build it.

I’m using that same box. Bare bones, just battery inside mine though. Glad to see someone else using it. Seems pretty water tight.
