Kastar 3-Pack Battery and LTD2 USB Charger Replacement for Sony

In this review the Kastar 3-Pack Battery and LTD2 USB Charger is evaluated for photographers who need extended shooting time without carrying the original Sony charger. The bottom line: this kit is for users of Sony cameras that accept the NP-FZ100 battery who want a compact, multi-battery solution that charges two batteries simultaneously and offers both Micro-USB and Type-C inputs. It is especially useful for travel and long shoots because the batteries are 2280mAh and the charger supports a 5V 2-3A input for faster USB charging.

Key Features

• Battery capacity: Each lithium-ion battery provides 2280mAh of power, which extends shooting time compared with a single in-camera battery.
• Dual charging: The LTD2 charger can charge two batteries at the same time, reducing downtime between sessions.
• Interchangeable plate: The charger allows the plate to be changed to support different battery placements, adding flexibility for varied battery types.
• USB convenience: With Micro-USB and Type-C inputs and a Micro USB cable included, the charger works from power banks, USB chargers, and laptop ports for on-location charging.
• Intelligent indicators: LED indicators show charging status and give a basic read on battery capacity so the user knows when batteries are ready to use.
• Compact power: The charger input accepts 5V 2-3A (15W) and the outputs are 8.4V 800mA per slot, making it a portable solution for most shooters.

Who It's For

This kit is aimed at mirrorless camera owners using Sony NP-FZ100 batteries, including users of the Alpha A7 III, A7 IV, A7R III, A7C, and A6600, who need spare power for long days of shooting or travel. It fits photographers and videographers who value compact USB charging options and the ability to top up two batteries without returning to a wall outlet.

Those who should look elsewhere include users who require manufacturer-branded batteries for warranty or professional rental houses that insist on official chargers. Also, if extremely rapid multi-battery charging from AC at higher amperage is required, a dedicated high-power desktop charger may be a better fit.

Pros & Cons
