I moved this content into a new thread, if anyone has built (or wants to build) a DIY power station, power pack, portable battery pack, etc...and you want to share your info, pics, etc, or ask questions, this is the thread for that!
-------------------------------------------------------------------------------
I have built a few DIY low-tech portable power 'stations' if you can call them that.
I wonder if a simple lead-acid battery and a very low tech charge controller, along with a basic solar panel would possibly solve the problem? The battery and charge controller can be installed in a metal enclosure, and possibly a USB charger. A basic 'dumb' phone can be placed inside the enclosure during charging.
A 12v to 120v inverter will always have some radiated RF and EMF but with it being inside a metal faraday cage, the radiated fields should be very low.
One of them I built I still have, and I built it with a lantern on top for those evenings around the picnic table or campsite, and with a couple of 12v ports for charging a phone, laptop, etc.
For those reading this and not familiar, RF and EMF are bothersome to some people, and as a ham operator we are now required to do a basic RF exposure survey of our own ham station and equipment. (this can be a simple online formula or more involved)
Near field RF and EMF can be an issue for some people at certain levels of exposure. There are also non-electric lighting options in the case of a power outage at night....various propane lanterns and Aladdin lamps come to mind.
