Kastar 2-Pack NP-FZ100 Battery and LTD2 USB Charger - Reliable Spare

In this review of the Kastar 2-Pack Battery and LTD2 USB Charger, the bottom line is simple: photographers who need dependable spare power and a flexible charging setup will find this kit practical and portable. The package pairs two NP-FZ100 compatible 2280mAh lithium-ion batteries with a dual USB charger that can top two cells at once and accepts both Micro-USB and Type-C inputs, so it suits travel shooters and weekend enthusiasts who want a compact backup solution without relying on camera-specific chargers.

Key Features

• Battery Type: Two 2280mAh lithium-ion cells provide extended shooting time compared with a single factory battery, giving photographers more capture time between charges.
• Dual Charging: The LTD2 charger can charge two batteries simultaneously, cutting overall downtime when multiple spares need replenishing.
• Switchable Plate: The charger allows changing the plate to accept different battery shapes, adding versatility for users with several camera models.
• USB Power Input: With Micro-USB and Type-C inputs and a 5V 2-3A 15W input spec, the charger works from power banks and common wall adapters for travel convenience.
• LED Status: Intelligent LED indicators show charging status and relative battery capacity, making it easy to tell when cells are ready without guessing.
• Compact Design: The charger and batteries are small and easy to carry, making them practical for day trips, shoots, or as part of a camera bag backup kit.

Who It's For

This kit is aimed at photographers who use cameras that accept the NP-FZ100 battery, including popular mirrorless bodies, and who want a portable way to carry spares and recharge on the go. Travel photographers and event shooters who need minimal downtime will appreciate the ability to charge two batteries at once and the USB input options for charging from power banks or USB adapters.

It is less suited for users who prefer original-brand batteries and chargers for warranty or OEM reasons, or those who require factory charging docks with camera-integrated charging features. Studio shooters who always have mains access and faster dedicated chargers might look for higher-output solutions.
