Built myself a portable power box for charging phones, Kindles, etc. And providing a power source for lights etc.
Should work well for Ice Fishing, Camping, etc.
Couple of 6 volt batteries I had laying around I wired for 12 volt. Will replace with a 12v 9 amp hour or greater soon.
The innards.
Volt meter and led switches, along with two banana jacks, USB and power plug.
Nice bright LED lights.
I’ll hook some LED strip lights up from the Banana Jacks for lighting Ice House up.
Once I managed to find all the components, it was a fairly easy build.
A little rough, but learned a lot for my next one.

Cool beans!!
