Smart Charger with Foldable Plug

The included charger delivers a 4.2 V, 600 mA output and uses a foldable flat pin for easier storage in a bag or pocket. A red LED shows charging status while a green LED signals standby or full charge, replacing the need for proprietary docks or USB-only solutions.
