Kastar 2-Pack Battery and USB Charger Replacement for JVC GZ-MG20

In this review the Kastar 2-Pack Battery and LTD2 USB Charger is judged on reliability and value for users of older JVC camcorders. The bottom line: this kit is for photographers and videographers who need extended run time and a flexible charging solution. It stands out because it pairs two 2400mAh Lithium-Ion batteries with a dual USB charger that can top up two cells at once and displays charging status, making it a practical spare kit for field shoots or long events.

Key Features

• High capacity batteries: Each 2400mAh battery provides extended shooting time compared with many stock cells, reducing mid-shoot interruptions.
• Dual charging: The charger can charge two batteries simultaneously, which speeds turnaround between shoots and keeps a backup ready.
• Interchangeable plate: The charger plate can be changed to fit different battery shapes, offering flexibility for compatible JVC battery models.
• USB powered: With Micro-USB and Type-C input options and a supplied Micro USB cable, the charger easily runs from power banks or laptop USB ports for on-location charging.
• Smart LED indicators: The intelligent LED display shows charging status and battery capacity so users can see progress at a glance.
• Compact and portable: The charger is lightweight and easy to carry, a useful convenience for travel or event work.

Who It's For

This kit is best for owners of older JVC camcorders that use BN-VF707, BN-VF714 or BN-VF7332 style batteries who need extra power for extended shoots or travel. It particularly suits run-and-gun videographers, hobbyists recording events, and anyone who prefers to carry spare batteries and a single compact charger rather than multiple OEM chargers.

Photographers who require the absolute fastest OEM charging times or those using cameras outside the listed compatible models should look elsewhere; compatibility is limited to the JVC models listed and the charger output is optimized for these battery types.

Pros & Cons

Pros

• Two high-capacity 2400mAh batteries provide noticeably longer runtime for continuous recording.
• Charger supports charging two batteries at once, reducing downtime between sessions.
• USB input options and an included Micro USB cable make on-location charging practical with power banks.

Cons

• The charger output is modest at 800mA per slot, so charging is not as fast as some higher-power dedicated chargers.
