Key item features

  • 【DIY 5600mAh Power Bank Case – Build Your Own Custom Charger】Solves the problem of buying expensive power banks that may not meet your exact needs. This DIY case lets you build your own custom power bank using two 18650 batteries (not included), giving you complete control over battery quality and capacity. The result is a 5600mAh power supply that you’ve assembled yourself—cost-effective, exactly to your specs, and easy to repair or upgrade. Perfect for electronics hobbyists, DIY enthusiasts, or anyone who prefers building over buying.
  • 【Tool-Free Assembly – Easy to Build, Even for Beginners】Addresses the intimidation of electronics projects that require soldering or specialized tools. This power bank case is designed for simple assembly—just slide the case from the bottom, insert two 18650 batteries (not included), slide the case back, and you’re done. No soldering, no wiring, no complicated instructions. The straightforward design makes it accessible for teenagers learning electronics, adults wanting a simple project, or anyone curious about how their devices work.
  • 【Versatile USB Output – Charges Phones, Bluetooth, MP3 & More】Eliminates the need for multiple chargers for different devices. The standard USB output ports work with a wide range of devices including phones (Xiaomi, Redmi, HTC, LG, Nokia, Samsung), Bluetooth accessories, MP3 players, MP4 players, and more. For devices with proprietary connectors like iPhones, simply use your existing USB cable. A versatile power solution for households with multiple device types, or for keeping as a backup charger in your bag or car.
  • 【Available in 2 Colors – Personalize Your DIY Power Bank】Tackles the lack of personalization in store-bought power banks. Choose from White, Blue, Pink, or Black to match your style or help distinguish your charger from others in your household. The sleek, lightweight case design looks professional while giving you the satisfaction of having built it yourself. Perfect for personal use, or as a thoughtful gift for the DIYer in your life.
  • 【Important Note: Not a Finished Product – Batteries & Soldering Not Required】Provides clear, honest information to ensure you know exactly what you’re buying. This listing is for the power bank case with circuit board only—you will need to purchase two 18650 batteries separately. No soldering is required for assembly, but you should be comfortable handling batteries and have basic DIY knowledge before purchasing. A transparent, straightforward offer for makers who want a simple, satisfying project. Use this case to create a custom power bank, to replace a worn-out casing, or as an educational project to learn about battery circuits and portable power.
