Kastar 3-Pack CGR-D28 Battery and AC Wall Charger Replacement

In this review the Kastar 3-Pack CGR-D28 Battery and AC Wall Charger replacement kit is presented for owners of older Panasonic camcorders who need dependable backup power. The bottom line: this kit is for users who want multiple full-capacity lithium-ion batteries and a compact wall charger so they can keep shooting longer without hunting for scarce OEM parts. Reviewers will appreciate that the batteries are 7.4V 3300mAh cells and the included charger supports wide input voltages, making it a practical replacement around the house or while traveling.

Key Features

• Lithium-Ion Battery Type: Provides higher energy density and lighter weight so cameras run longer without adding bulk.
• 7.4V 3300mAh Capacity: Offers extended runtime compared with many single-use replacements so users can capture longer events between charges.
• Foldable Flat Pin Charger: The AC wall charger has a foldable pin for compact storage and easier transport in a camera bag.
• Wide Input Range: The charger accepts AC 100~240V 50~60Hz so it works internationally with the right adapter.
• LED Charge Indicator: Built-in LEDs show red while charging and green when on standby or fully charged, simplifying charge status checks.
• Three Batteries Included: The package contains three batteries plus one AC charger to keep multiple spares available for long shoots.

Who It's For

This kit is aimed at videographers and hobbyists who use compatible Panasonic camcorders and need affordable, ready-to-use replacement batteries. It suits event shooters, travel videographers, and anyone who prefers carrying multiple spare cells rather than relying on a single battery and frequent recharges.

It is less appropriate for professionals who require branded OEM service support or integrated camera systems that depend on manufacturer-specific battery software. Also, travelers to countries with different outlet shapes will need a plug adapter since the kit does not include car adapters or European plugs.
