#CarSleeping #PowerBank #MakingAPowerBank ○ Introduction https://blog.naver.com/mp_esbang/2221... ○ Esbang YouTube [    / @esbangtv   ] ○ Esbang Blog [ https://blog.naver.com/mp_esbang ] ○ Esbang Instagram [   / seung76hyun   ] As you all know, a power bank is essential for outdoor car camping enthusiasts like me. Especially in the winter, without a power bank, I might start to hate car camping altogether. When I started car camping and faced my first winter, I went crazy. I survived the winter nights with things like hot packs, lol. I finally got through the winter and got a power bank. But honestly, I rarely use a power bank in the summer. These days, even electric fans are rechargeable, so power banks are useless in the summer except for charging phones. But now winter is here. Power banks, essential in winter, are actually quite expensive. A 100Ah battery can cost close to a million won. That's an out-of-the-box price for a novice car camper like me. I was wondering what other options there were, and I found this solution. And it's the one I'm using now in the winter. It uses an industrial battery. (A car battery would work, too.) === The rest of the story: [ https://blog.naver.com/mp_esbang/2221... ] You can check it out here. ===
