Kastar 2-Pack NP-FZ100 Battery and USB Dual Charger - Portable Power

In this review of the Kastar 2-Pack NP-FZ100 Battery and USB Dual Charger the bottom line is simple: it is for photographers who need reliable backup power and flexible charging on the go. The package pairs two 7.2V 2280mAh lithium-ion batteries with a compact dual charger that accepts both Micro-USB and Type-C input, so users who travel or shoot long events get extra runtime and convenient USB charging options. Our review found the unit especially useful when paired with Sony Alpha series cameras that use the NP-FZ100 battery.

Key Features

• Dual battery pack: Two NP-FZ100-compatible batteries provide immediate spare power to double shooting time without waiting for a recharge.
• Dual-slot charger: The charger can charge two batteries at the same time or switch to single-slot operation by changing the plate for different battery configurations.
• USB power options: With Micro-USB and Type-C inputs and a 5V 2-3A 15W input rating, the charger can be powered from power banks, laptop USB ports, or common wall adapters.
• LED status indicators: Intelligent LED display indicates charging status and battery capacity so users know when batteries are ready.
• Portable design: The charger is compact and easy to carry, making it suited to location work, travel, and long shoots where AC power is not guaranteed.

Who It's For

The Kastar 2-Pack is aimed at mirrorless camera owners who use the Sony NP-FZ100 battery, including shooters of Alpha 9 series and recent Alpha A7 models, who need extra runtime for events, weddings, travel or extended video recording. It is also a good fit for photographers who value USB charging flexibility and a compact charger they can pack in a camera bag.

It is less appropriate for users who insist on manufacturer-branded batteries or who require official two-year manufacturer support; those buyers may prefer factory replacements. It is also not a replacement for multi-bay professional chargers with integrated AC adapters if studio charging speed and advanced battery management are required.

Pros & Cons

Pros

• Includes two 7.2V 2280mAh batteries to extend shooting time without interruption.
• Charges one or two batteries simultaneously with clear LED charging indicators.
• Multiple input options including Micro-USB and Type-C make it convenient with modern power banks and adapters.

Cons

• Not an official Sony-branded battery or charger, so buyers who prefer OEM parts may opt elsewhere.
• Charging rate is modest (8.4V 800mA per slot) so refill times are not the fastest compared with high-power studio chargers.
