插座不夠用？那就把鋰電池裝進設備裡

This video shares a practical device modification case: Converting a device that originally only required a transformer into one powered by a built-in lithium battery. Not only can it be charged directly, but the battery level can also be displayed in real time, greatly increasing its usability! 🎬 The video will fully demonstrate: ✅ How to assess the internal space of the device and choose the appropriate lithium battery ✅ How to match the lithium battery charging board and boost circuit ✅ Boosting the 3.7V lithium battery to the device's required 12–15V ✅ Adding a power switch and battery level display module ✅ Safe connection, spot welding, and insulation treatment of the lithium battery This is a modification idea that can be practically applied to various plugged-in devices. Hopefully, it can inspire you to create more practical modifications that will truly benefit your life 😊 If you also like this kind of electronic modification, practical device upgrade, or making inconvenient things "more useful," please subscribe to [Hedgehog Help], and don't forget to like, share, and turn on notifications. 📌Tools Used in the Video📌 🦔Screwdriver with Touch Control👉https://lihi.cc/89RxG 🦔Power Supply👉https://lihi.cc/Tbvwg 🦔Thermostatic Soldering Iron👉https://lihi.cc/BkiTD 👀👀👀【Follow Hedgehog Gang】👀👀👀 🦔More Fun Videos👉   / @hedgehogtw   🦔Hedgehog Gang Official Website👉https://www.hedgehog.com.tw 🦔Hedgehog Gang Facebook 👉  / kchedgehog   🦔Hedgehog Gang Instagram 👉  / hedgehog.com.tw   #LithiumBatteryModification #Plug-inEquipmentModification #Built-inLithiumBattery #DCBoostCircuit #LithiumBatteryChargingPad #PowerIndicatorModule #PowerBankModification #DIYElectronics #ElectronicEngineering #Maker #HedgehogHedgehogGroup #BatteryPoweredDevice #DIYelectronics #BatteryUpgrade
