Kastar 2-Pack NP-FV100 Battery and USB Charger - Extended Run

In this review the Kastar 2-Pack NP-FV100 battery and USB charger is assessed as a practical, budget-conscious power kit for owners of older Sony-compatible camcorders and prosumers. The bottom line: this pack is for users who need long runtime and flexible charging without lugging original AC chargers. The 5750mAh lithium-ion cells and a dual USB charger that accepts Micro-USB or Type-C input make it useful on location shoots, travel, or multi-camera setups, and the intelligent LED indicators simplify monitoring charge status.

Key Features

• High capacity battery: The 5750mAh, 7.2V lithium-ion cells provide noticeably longer runtime than many stock batteries, reducing downtime between takes.
• Dual charging: The charger can charge two batteries simultaneously, which helps keep a second battery ready while the first is in use.
• Interchangeable plate: The charger allows changing the plate to fit different battery plates, offering flexibility for several NP-FV series packs.
• USB powered: The charger accepts 5V 2-3A input via Micro-USB or Type-C and runs from portable power banks or USB adapters for on-the-go charging.
• Smart LED indicators: The charger displays charging status and battery capacity with LEDs, so users can quickly see when a pack is topping up.
• Compact and portable: With a low 15W input and a small footprint, the kit is easy to carry in a camera bag without adding much weight.

Who It's For

This bundle is aimed at videographers and hobbyists using Sony NP-FV-compatible cameras who want extended run time and a compact charging solution. It suits event shooters, documentary makers, and travelers who rely on USB power sources and need two batteries ready during medium-length shoots.

It is less appropriate for buyers who require manufacturer original batteries for warranty reasons or those needing ultra-fast charging beyond the stated 800mA outputs. Users with newer camera systems that use different battery formats should look for a model specific to their camera.

Pros & Cons

Pros

• Long 5750mAh capacity that increases usable camera time between swaps.
• Can charge two batteries at once, which is convenient for continuous shooting days.
• USB input options including Micro-USB and Type-C lets you charge from power banks or USB adapters.
• Intelligent LED display provides clear charge status and capacity information.

Cons

• Charging output is limited to 800mA per slot, so charging is not especially fast compared with higher-power dedicated chargers.
• Not an original manufacturer battery, so photographers preferring OEM parts may choose differently.
