I’m only half kidding. I’m a bit of a prepper and I have lots of powerbanks and devices that charge from USB but besides idling my truck I really had no other way to charge any of them in case of a long-term power outage which seemed a bit of an oversight on my part.
Not like this solves the issue. 30 watts (under ideal conditions) isn’t much but it’s a start.
My house is quite rural and I have a water well with a battery backup for the pump and UV filter. The battery lasts for about 5-6 days depending on use. I can charge the battery from the grid or with solar.
If the cities get nuked, my well system will still function.
Can you repair it if it breaks?
Most of it. I rebuilt the well system when I bought the house. I installed the backup system from various components. It wasn’t a pre-built system. I COULD conserve power by shutting off the UV filter. I could probably run the pump for over a month on a single charge.
If something blows in the charge unit in the battery pack, and I can’t find a replacement part, then no. If the batteries fail, I can hack together a replacement if I can get batteries. I have various solar panels and charge controllers around and a 12k panel system on the roof I could tap into and convert if the grid stops. The well system can also run on a propane generator, but as we learned in Fiona, when the entire island (PEI) was dark for 11 days, propane supplies go quick. I had 8 full tanks so I was fine.
But that’s the same for anything in a house. If the world goes to shit, something happens and I break my toilet, and can’t find a replacement, then I’m shitting in the woods.
We did a battery backup system! I think we’ll do panels next. Did you buy enough panel generation to replace it as you use it?
We bought the ecoflow batteries; we haven’t shopped around for panels yet. I was hoping their panels were competitively priced so we could kind of just plug 'n play.
