Kastar 3-Pack NP-FV100 Battery and USB Charger - High Capacity Power

In this review the Kastar 3-Pack NP-FV100 battery and LTD2 USB charger is evaluated for videographers and camera owners who need reliable runtime without carrying bulky chargers. The package combines three 5750mAh lithium-ion cells with a dual-slot USB charger that accepts Micro-USB or Type-C input, so the single biggest reason to buy is extended shooting time paired with flexible charging options. It is a practical replacement for original NP-FV100 batteries and offers simultaneous charging and a compact charging footprint for travel and field work.

Key Features

• High Capacity: Each 7.2V battery provides 5750mAh capacity for longer recording sessions compared with many standard replacements.
• Dual Charging: The charger can charge two batteries at the same time, reducing downtime between shoots.
• USB Powered: With Micro-USB and Type-C input and a 5V 2-3A 15W input spec, the charger works from power banks or laptop USB ports on location.
• Intelligent LED Display: The USB dual charger uses LED indicators to show charging status and battery capacity so users can monitor progress at a glance.
• Interchangeable Plate: The charger can change plates to support different battery sizes, adding convenience for mixed battery kits.
• Compact and Portable: The charger is easy to carry and the USB input lowers the need for bulky AC adapters when traveling.

Who It's For

This kit is aimed at independent filmmakers, wedding shooters, and content creators who use Sony NEX and HXR series cameras and want more runtime without constantly swapping batteries. The three-battery pack is useful for day-long shoots where recharging opportunities are limited and the USB input makes it convenient to top up from a power bank between locations.

Users who require factory original chargers with proprietary fast-charge protocols, or who must match specific manufacturer warranties, should look elsewhere. Also, those who need an AC-only desktop charger with higher amp outputs might prefer a different dedicated charging solution.

Pros & Cons

Pros

• High 5750mAh capacity delivers noticeably longer run times for video recording.
• Dual-slot USB charging reduces downtime by charging two batteries simultaneously.
• Flexible input options (Micro-USB and Type-C) make on-the-go charging convenient.
• LED indicators provide clear feedback on charging status and relative capacity.

Cons

• Charging current per slot is modest (800mA), so full recharge times are longer than some high-speed chargers.
• Not a factory-branded Sony charger, so users preferring OEM accessories may be cautious.
