4000mAh Battery 4-Pack with AC Wall Charger - Compatible

In this review the focus is on practical power for older Panasonic camcorders: the Kastar 4-Pack includes four 4000mAh lithium-ion replacement batteries plus a foldable-pin AC wall charger, and it is aimed at videographers who need reliable spares. The bottom line is simple: this kit delivers extended runtime and a convenient charger that handles 100~240V input, making it ideal for travel and long shoots. The reviewer found the batteries offer predictable capacity and the charger provides clear LED status indicators during charging.

Key Features

• High capacity batteries: Each 4000mAh lithium-ion cell provides extended run time so users can shoot longer between charges.
• Wide voltage charger: The included AC wall charger accepts AC 100~240V 50~60Hz, allowing use in many countries without a voltage converter.
• Clear charge indicators: The charger uses a red LED while charging and a green LED when on standby or fully charged, making status easy to read at a glance.
• Compact charger design: The charger has a foldable flat pin for neater storage and reduced risk of bent prongs during transport.
• Model compatibility: The kit is compatible with a long list of Panasonic battery model equivalents and camcorder models, reducing compatibility guesswork.

Who It's For

This kit is best for hobbyist and semi-pro users who own one of the supported Panasonic camcorder models and who need multiple replacement batteries for day-long shoots, events, or travel. The high 4000mAh capacity is suited to users who prefer carrying spares rather than relying on a single battery and intermittent charging.

It is less well suited for users who require a vehicle charger or a European plug included in the package, since the car adapter and alternate plug types are not included. Professionals who need manufacturer original batteries for warranty reasons should also consider OEM options instead.

• Charger supports global AC 100~240V input, useful for travel without a converter.
