I&amp;#x27;ve only been running it for a few months now, but I&amp;#x27;ve been using it to keep all of my USB devices charged during that time.&lt;p&gt;In an actual power outage, I can even plug in my modem, router, and AP—using DC barrel jacks for the modem and router and a DIY PoE injector for the AP—so as long as the upstream infrastructure is still powered I&amp;#x27;ll be able to keep working.&lt;p&gt;Since I rent, I can&amp;#x27;t do a roof-mount or grid-tie system, so I opted instead to build a 12V DC system. I purchased a used solar panel and I&amp;#x27;ve assembled a ~0.5kWh battery from used packs.&lt;p&gt;I&amp;#x27;m using insulated nickel strips to pass the solar panel cables through a closed closed window in a way that doesn&amp;#x27;t require drilling holes and has a minimum impact on the insulation seal of the window (although insulation in the UK really sucks anyway).&lt;p&gt;Most of the fittings and wiring have been used and come mostly from automotive scrap (an advantage of using common 12&amp;#x2F;24V standard fittings), so the financial cost has been very low. That said collecting use battery packs, testing cells, and assembling them into new battery packs certainly takes time.</text><parent_chain></parent_chain></comment><story><title>UK Plans for Three-Hour Power Blackouts in Event of Gas Shortages</title><url>https://news.sky.com/story/energy-crisis-plan-for-three-hour-power-blackouts-to-prioritise-heating-in-event-of-gas-shortages-12713253</url></story>

The Tory agenda now seems fixed upon ensuring the very rich have everything and everyone else has absolutely nothing.</text><parent_chain></parent_chain></comment><story><title>UK Plans for Three-Hour Power Blackouts in Event of Gas Shortages</title><url>https://news.sky.com/story/energy-crisis-plan-for-three-hour-power-blackouts-to-prioritise-heating-in-event-of-gas-shortages-12713253</url></story>
