DIY Power Bank with LCD Display | Homemade Portable Charger

This is a homemade DIY power bank that I built using lithium battery cells, a boost converter module, and an LCD display. This power bank can charge smartphones and other USB devices efficiently and safely.

The LCD screen shows the battery percentage and voltage, allowing easy monitoring of the power level. It has dual USB output ports, so multiple devices can be charged if needed. The compact and simple design makes it portable and useful for everyday use.

This project demonstrates how to build a functional and reliable power bank at home using basic electronic components. It is a great project for learning electronics, battery management, and power conversion.

Features:
• LCD battery percentage display
• Dual USB output ports (5V output)
• Rechargeable lithium battery
• Portable and compact design
• Suitable for charging smartphones and USB devices

This DIY power bank is useful for emergency charging and helps understand how commercial power banks work.
