This makes it a highly versatile charger for all your battery needs. Intelligent Charging Technology: The i4 features smart circuitry that automatically detects battery type and status, adjusting the voltage and charging mode for optimal performance. This ensures that each battery receives the correct charge, just like the i2, but with the added convenience of charging more batteries at once. LED Status Indicators: The i4 is equipped with four LED indicators—one for each bay—that clearly display the charging status of each battery. This simple and intuitive interface allows you to easily monitor your batteries as they charge. Advanced Safety Protections: Safety is a top priority with the Nitecore i4, which includes protections against reverse polarity, overcharge, short circuits, and overheating, ensuring that your batteries are always charged safely. Efficient Charging: The i4 features optimized charging rates, making it more efficient than the i2 when handling multiple batteries. This means you can charge your batteries faster and get back to using your devices sooner. Compact & Durable Design: Despite its increased capacity, the i4 maintains a compact and portable design, making it easy to carry and store. Its robust construction ensures long-lasting durability, even with frequent use.  For users who appreciate the reliability and simplicity of the Nitecore i2 but need more capacity, the Nitecore i4 offers the perfect upgrade. With its ability to charge four batteries simultaneously and its enhanced efficiency, the i4 is an excellent choice for those who need more from their charger without sacrificing safety or ease of use.
