Broken USB-C Rechargeable Chinese Fan - Can I fix it?

Got a broken USB-C rechargeable fan from a Chinese brand and wondering if it’s even worth cracking open? I did, and in this video I’m diving deep into the guts of this cheap but surprisingly popular gadget to see if a repair is actually possible. From dead batteries to dodgy charging circuits, I’m testing every component to find the real culprit and show you exactly what it takes to bring this thing back to life. These affordable USB-C fans are everywhere, but their build quality can be a total lottery. If you’ve got one that won’t charge, won’t spin, or dies after five minutes off the cord, you’ve come to the right place. In this hands-on teardown, I’m not just guessing—I’m using a multimeter to trace the power path, checking the 18650 cells for voltage, and inspecting the control board for cold solder joints or failed regulators. You’ll learn how to diagnose the most common failure points without any fancy lab gear. Why does this matter? Because replacing a £3 fan every summer is wasteful, and most of these units share the same generic internals. Once you see how the charging IC and protection circuit work, you’ll be able to fix not just this fan, but a whole category of broken USB-C gadgets. I also cover safety basics—like why you shouldn’t just poke at a swollen battery—and what tools actually make the job easier. Whether you’re a beginner who’s never soldered or a tinkerer looking for a satisfying project, this guide walks you through the entire process step by step. By the end of the video, you’ll know if this specific fan is salvageable or if it’s toast. I’ll be honest about the cheap parts and where the shortcuts were taken, and I’ll give you my verdict on whether a repair beats a replacement. If you’ve ever thrown up your hands at a dead gadget, watch this first—you might be surprised at what a little patience and a soldering iron can do.
