Kastar 2-Pack SB-L320 Battery and AC Charger - Reliable Power

In this review the Kastar 2-Pack SB-L320 Battery and AC Wall Charger is evaluated for photographers who depend on legacy Mamiya and Leaf medium format bodies. The bottom line: this bundle is for users who need a straightforward, cost-effective replacement power solution that matches original battery voltage and provides a convenient foldable AC charger. It performs as expected for extended shoots thanks to the pair of 4800mAh lithium-ion cells and delivers clear charge status via an LED indicator, making it a practical substitute when original batteries are unavailable.

Key Features

• High capacity cells: Each 4800mAh lithium-ion battery provides extended shooting time so fewer mid-day battery swaps are required.
• Correct voltage: The 7.4V battery chemistry matches compatible Mamiya Leaf cameras to ensure predictable performance and safe operation.
• Universal charger input: The AC charger accepts 100~240V 50~60Hz input, which means it can be used worldwide with a local plug adapter for travel.
• Simple charge feedback: A red LED shows charging and a green LED indicates standby or full-charge, so the user always knows battery status at a glance.
• Compact charger design: The charger includes a foldable flat pin for easy storage and to reduce clutter in a camera bag.
• Practical package: The kit includes two batteries plus one wall charger, which is useful for a primary and backup battery rotation.

Who It's For

This kit is aimed squarely at photographers who own Mamiya Leaf medium format cameras listed as compatible, and who need a reliable replacement without paying for rare OEM parts. It works well for studio shooters who value longer runtimes and travel shooters who appreciate the chargers wide input range and foldable plug.

It may not be the best choice for users who require in-car charging or a European plug included in the box, since the package does not contain a car adapter or extra international plug set. Also, those who must confirm manufacturer warranty coverage should consult the original camera manufacturer for OEM replacements.
