Backup Systems both home and portable

If not an EMP, then I would be more worried about a supply of Potassium Iodide tablets and a way to avoid the fallout and decontaminate myself and my supplies. A Geiger counter would be nice. As for a Puerto Rico kind of regional disaster -- there is no such thing as sharing as your capabilities would be exhausted in a matter of hours. The preparation for that type of disaster should be to be mobile enough to move out of the affected area and into an area where you can reestablish an income flow and be able to live without emergency restrictions.

Actually, I was thinking more that I'd get vaporized in a direct nuclear hit, and wouldn't therefore have to manage a CPAP. A bigger concern is if the electric grid gets taken out for an extended period of time.

An infrastructure hack would present similar obstacles.

In emergencies, people have a general tendency to be supportive of one another. Sometimes, there's a trade off between sharing and consuming. A solar panel would reduce the conflict between those two things, since the power source would be repetitively re-chargeable. Letting someone else recharge a phone for 15 minutes may be exactly that kind of situation.

Puerto Rico is not a situation where you can leave. Same is true for many other catastrophes: there's no warning and you're stuck in place.

Great idea about color-coding the cables.

Thanks for the tip on the DC-DC converter. I'll use that with the Yeti.

If you have an interest, I can go into more detail as to calculating current draw or even measuring current.  You may search some of my other posts because I've already done several.



What are you doing about connectors? I am thinking about switching everything over to Anderson PowerPole Color-coded connectors using some of the slick products from Powerwerx like the cigarette connection to powerpole.

I LOVE me some PowerPoles! I once got to the point where I'd think up projects just so I could use them. Actually, I started out with hooking up a battery to run a GPS in the antique plane that lacked any electrical system. Then I graduated to an infatuation with backup power for my CPAP and I'll admit, I went overboard (have the big 140 w solar panel and controller/charger to refill the batteries). All of that kind of led me into the radio hobby...

Be careful! They get addictive.

The TriCrimp tool is a must.

Everything I have that is DC wired has a PowerPole connection on it that eliminated pretty much all the OEM connectors provided with anything. Heck, I've even bought cheap lamps at Target and snipped the plug to install power poles - I found 12 V LED bulbs and they run fine in those lamps (another hack I got from a pal in Floiduh - clamp-on worklights with the bowl shaped aluminium shade from the hardware store using the 12 V LED bulbs for outage situations for light focused where you need it).
