Kastar 2-Pack CGR-D28 Battery and AC Wall Charger - Reliable Power

In this review the Kastar 2-Pack CGR-D28 Battery and AC Wall Charger is evaluated for videographers who need dependable spare power for older Panasonic camcorders. The bottom line: this kit is aimed at owners of cameras like the AG-DVC80P and AG-DVX100 series who want a cost-effective replacement that matches the original batteries' form and voltage. The reviewer found the lithium-ion 7.4V, 3300mAh cells deliver predictable runtime and that the included AC charger with a foldable flat pin is convenient for travel and everyday charging needs.

Key Features

• Battery Type: The lithium-ion cells provide higher energy density and lighter weight than older chemistries, making them practical for long shoots.
• Battery Capacity: The 3300mAh capacity offers extended recording time per charge compared with lower-capacity replacements, reducing the need to swap batteries mid-session.
• Voltage Compatibility: The 7.4V nominal voltage matches the original CGR-D28 form factor so cameras recognize the power source without unusual behavior.
• AC Charger Design: The charger accepts 100~240V 50~60Hz worldwide input and has a foldable flat pin for easy storage and transport.
• Charge Indicator: The LED system shows red while charging and green when full or on standby, making the charge status easy to confirm at a glance.
• Package Value: The kit includes two batteries plus one AC charger, which is useful for shooters who need immediate spares without buying extras separately.

Who It's For

This kit is best for owners of compatible Panasonic camcorders such as the AG-DVX100, AG-DVX102, AG-DVC80 series and other listed models who need a direct replacement battery set and a single charger to keep on a desk or take on the road. Independent filmmakers, news shooters, and event videographers using those specific models will appreciate the straightforward compatibility and extra runtime.

Those who require a car adapter or a European plug should look elsewhere or plan to buy adapters separately, since the package does not include a car adapter or continental plugs. Buyers of very new camera systems that use different battery families should not purchase this kit.
