Kastar 4-Pack NP-FV70 Battery and LCD AC Charger Kit - Reliable Power

In this review the Kastar 4-Pack NP-FV70 Battery and LCD AC Charger Kit is evaluated for users who need dependable replacement power for compatible Sony camcorders. The bottom line: this kit is for videographers and hobbyists who want multiple spare batteries and a charger that shows charge status and remaining capacity. It is not a premium OEM battery, but its 2650mAh lithium-ion cells and the LCD-equipped charger make it a practical, cost-effective solution for extended shoots, travel, or backup power where convenience and clear charge feedback matter.

Key Features

• High capacity battery: Each battery delivers 2650mAh at 7.2V to extend runtime compared with older low-capacity packs.
• LCD AC charger: The included charger displays charging status and battery capacity so users can confirm remaining power at a glance.
• Worldwide input: The charger accepts AC 100~240V 50~60Hz making it suitable for travel without a separate adapter.
• Compact storage: The charger has a foldable flat pin design that keeps the kit compact and easier to pack in a camera bag.
• Multi-pack convenience: The 4-pack of batteries plus one charger provides enough spares to swap batteries during long recording sessions.

Who It's For

This kit is best for independent videographers, event shooters, or owners of compatible Sony camcorders who need multiple replacement batteries and an informative charger to manage power between takes. The LCD readout helps when juggling several cells so you know which ones are ready and which need charging.

It is less suited to someone who requires official manufacturer batteries for warranty or longest-term durability guarantees, or to users who need ultra-high-discharge packs for specialized professional rigs. Casual users who only need one spare battery may also find a 4-pack excessive.

Pros & Cons

Pros

• Good runtime from each 2650mAh battery, reducing mid-shoot swaps.
• Charger shows both charging status and battery capacity for quick checks.
• Foldable flat pin on the charger keeps the kit compact for travel and storage.

Cons

• Not an official Sony-branded battery, so buyers seeking OEM packaging should look elsewhere.
• Charger output is DC 8.4V 800mA which is adequate but not optimized for very rapid charging.
