Kastar 2650mAh 3-Pack Batteries with LTD2 USB Dual Charger - Triple

Our review of the Kastar 3-Pack with LTD2 USB dual charger finds it best suited for owners of older Sony camcorders who need reliable spare power and flexible charging on the go. The single biggest reason to buy is the combination of three high-capacity 2650mAh lithium-ion batteries plus a dual USB charger that can charge two batteries at once, which replaces multiple originals and reduces downtime during shoots. This review focuses on how well the kit matches the original Sony NP-FV50/NP-FV70/NP-FV100 battery family and whether the charger is convenient for travel and field use.

Key Features

• High capacity cells: Each 7.2V 2650mAh lithium-ion battery gives extended run time for long recording sessions and fewer battery swaps.
• Dual battery charging: The LTD2 charger can charge two batteries simultaneously, cutting overall charging time compared to single-slot chargers.
• Adjustable plate: The charger plate can be changed to fit different battery shapes so it works with multiple NP-FV series cells.
• USB powered: With Micro-USB and Type-C input options and a 5V 2-3A input spec, the charger is compatible with common power banks and USB adapters for travel charging.
• Clear status indicators: Intelligent LED indicators show charging status and relative battery capacity so it is easy to monitor progress at a glance.
• Portable design: The compact charger and included Micro-USB cable are easy to pack in a camera bag for shoots away from a studio.

Who It's For

The kit is aimed at videographers and hobbyists using Sony camcorders that accept NP-FV series batteries who need more runtime and the convenience of charging multiple batteries from USB power. It is a practical choice for travel shooters who rely on power banks or car adapters since the charger accepts common USB inputs.

Those who require official manufacturer chargers with branded warranties or who use camera systems that need different voltages should look elsewhere; this is an aftermarket kit intended to replace or supplement factory batteries and chargers on compatible models only.

Pros & Cons

Pros

• High 2650mAh capacity offers noticeably longer recording time than many standard replacement cells.
• Dual charging saves time and the adjustable plate increases compatibility across NP-FV variants.
• USB input with both Micro-USB and Type-C options makes field charging straightforward from power banks.

Cons

• Not an official Sony product, so warranty coverage and OEM compatibility are dependent on individual camera behavior.
