00:00Okay, so imagine this, the power's out, your phone's at 3%, and you're stuck with zero
00:05way to charge anything.
00:06That's exactly why I went down the rabbit hole of DIY power bank boxes, the kind where
00:11you pop in your own 18,650 cells and build a backup battery for emergencies.
00:16I hunted through thousands of listings and found the top 5 DIY power bank boxes for emergencies,
00:22so let's get into them.
00:24First up, the 18650 battery charger case with a nightlight and LCD display.
00:30This one's awesome because that little screen actually shows you the exact battery percentage,
00:34and the built-in nightlight is genuinely handy during a blackout.
00:38It's only $6.45, it's sold over 4,600 times, and it's sitting at a 4.9 rating.
00:45For under 7 bucks, that's a no-brainer for a kit that does double duty as a flashlight.
00:51Next, the DIY Free Welding 18650-21700 Aluminum Power Bank Kit.
00:58The best part here is no soldering, no welding, you just drop your batteries in, and it works,
01:03which makes it perfect if you've never built one of these before.
01:06It's just $4.90, it's got 4,500 plus sales and a 4.9 rating, and honestly, at that price,
01:13it's the cheapest way to get into DIY power banks without any tools.
01:18Third on the list, the 3x18650 battery charger case with double USB output.
01:24What I love is those two USB ports, so you can charge two devices at once,
01:28plus it's got that LED nightlight again. It's $7.14, over 4,000 sold, 4.9 stars,
01:36and it's a great middle ground, small enough to pocket, but with enough cells to actually get
01:40you through a long outage. Coming in fourth, the 8x18650 battery charger box with a digital display.
01:48This thing is a capacity monster 8 cells means serious runtime,
01:52and the LED display keeps you posted on exactly how much juice you've got left.
01:56It's $7.90, with nearly 4,000 sales and a 4.7 rating, and if you want maximum backup power
02:03for
02:03barely more than the smaller ones, this is your pick. And number 5, the PD65W battery storage box
02:11with 8-cell support. This is the premium option, 65 watts of PD fast charging means it can even top
02:17up a laptop, and it's got both USB and Type-C plus a digital display. It runs $17.76, it's
02:25sold over
02:253,500 times at 4.9 stars, and yeah, it costs more, but for emergency power that can handle real
02:32devices fast, it's absolutely worth it. So there you go 5 solid DIY power bank boxes for emergencies,
