I Built a 7200mAh Transparent Power Bank 🔋 (Crazy Fast Charging!)

Описание: In this video, I show you how I built a fully transparent power bank using 4 lithium-ion batteries and a custom-cut 3mm acrylic case. You’ll see the entire process — from finding the right charging/discharging control board to assembling and testing the final design.

The electronic module used is a DIY Power Bank Charging Board (5V 2.4A Output + QC Support), which handles both charging the batteries and powering your devices.
