Four-Battery Kit with Wall Charger

This pack supplies four lithium-ion cells rated at 7.4 V and 2300 mAh alongside a compact AC wall charger. It targets owners of compatible Sony Handycam and Cyber-shot models who need spare power for extended shoots or travel. The charger accepts 100–240 V input for worldwide use.

Foldable Plug and LED Status

The charger features a foldable flat pin that reduces bulk in a bag and plugs directly into a wall outlet without a separate cable. A red LED shows active charging while a green LED signals standby or a full cell. No additional adapters or software setup are required.

Steady 600 mA Charge Rate

Each cell receives a constant 8.4 V at 600 mA during the charge cycle, delivering a consistent current rather than a rapid burst. This approach keeps cell temperature moderate during prolonged charging sessions and supports the 17 Wh capacity over repeated cycles.
