Kastar 4-Pack Replacement Battery and USB Charger for Sony NP-FZ100

In this review the Kastar 4-Pack replacement battery kit is evaluated for photographers who need extended runtime for Sony mirrorless cameras that use the NP-FZ100 battery. The bottom line: this kit is for shooters who value carrying multiple lightweight spares and a compact USB charger that can power two batteries simultaneously. The reviewer found the lithium-ion 2280mAh cells and the intelligent dual USB charger to be practical for long shoots and travel, delivering reliable power without the bulk of a larger desktop charger.

Key Features

• Battery Type: The kit uses 7.2V lithium-ion 2280mAh cells that provide a reliable balance of capacity and weight for mirrorless camera use.
• Dual Charging: The charger can charge two batteries at the same time, which reduces downtime between shooting sessions.
• Interchangeable Plate: The charger plate can be changed to support different batteries, adding versatility for users with multiple battery types.
• USB Power Input: The charger accepts Micro-USB and Type-C input and runs from a 5V 2-3A source, making it easy to power from power banks or laptop ports.
• LED Status Display: An intelligent LED display shows charging status and relative battery capacity so users can monitor progress at a glance.
• Portable Design: The compact charger and included Micro USB cable make this kit easy to pack for travel and field work.

Who It's For

The Kastar 4-Pack is aimed at active photographers and hybrid shooters who use Sony cameras compatible with NP-FZ100 batteries and who need several full spares for long days, multi-day trips, or when access to AC power is limited. It is particularly useful for wedding photographers, travel shooters, and videographers who benefit from fast turnaround between battery swaps.

Those who should look elsewhere include professionals who require manufacturer-authorized batteries or ultra-rapid single-battery chargers that match OEM desktop chargers; also users who need official OEM warranty support may prefer original brand batteries and chargers.

Pros & Cons

• Multiple batteries in a compact pack provide extended shooting time without frequent recharging.
• The dual USB charger supports two batteries at once and accepts both Micro-USB and Type-C input for flexible power options.
• Intelligent LED indicators make it easy to monitor charge status and remaining capacity.

Cons

• These are third-party replacement batteries and chargers rather than OEM units, so buyers seeking factory-issued accessories may prefer original parts.
