Kastar NP-FM50 4-Pack Battery and LTD2 USB Dual Charger - Reliable

In this review the Kastar NP-FM50 4-pack and LTD2 USB dual charger is evaluated for users who still rely on older Sony camcorders and cameras. The bottom line: this kit is for photographers and videographers who need dependable spare power and flexible charging without carrying bulky wall chargers. Tested for capacity and convenience, the pack combines four 7.4V 2300mAh lithium-ion camera batteries with a USB charger that can replenish two batteries at once or swap plates for other compatible packs.

Key Features

• High capacity: Each 7.4V 2300mAh battery delivers extended run time compared with many OEM single-cell spares, helping reduce interruptions in field shoots.
• Dual charging: The LTD2 USB charger can charge two batteries at the same time, cutting wait time when multiple spares need topping up.
• Swappable plate: The charger includes a changeable plate to charge different compatible battery models, making it useful for mixed camera kits.
• USB powered: With Micro-USB and Type-C input options and a supplied Micro USB cable, the charger works from power banks, laptop ports, or a USB wall adapter for on-the-go charging.
• LED status: Intelligent LED indicators display charging status and relative battery capacity, so users can tell when cells are ready without guesswork.

Who It's For

This kit is ideal for owners of older Sony camcorders and compatible cameras that accept NP-FM50 style batteries, such as several DCR and CCD series models. Video shooters who need multiple spares for long shoots or travel will appreciate the extra capacity and the ability to charge two batteries simultaneously.

It is less suitable for users who require a proprietary OEM charger with manufacturer firmware or for those who need ultra-rapid professional charging beyond the 800mA outputs provided. If you only use a single battery and rarely shoot, the 4-pack may be more than necessary.

• Micro-USB and Type-C inputs plus a supplied cable allow charging from power banks and common USB supplies.
