Kastar Fully Decoded 4-Pack Battery and LCD AC Charger - Reliable

Our review of the Kastar 4-Pack Fully Decoded Battery and LCD AC Charger finds it best suited for photographers who need dependable spare power for Olympus OM-D bodies without fuss. The package bundles four lithium-ion 1750mAh batteries with a single LCD AC charger so a user can keep multiple batteries rotated during long shoots. The standout here is the charger display that shows charging status and remaining capacity, which makes it easy to manage power between sessions and verify battery health even when the charger is not hooked to AC power.

Key Features

• Fully decoded batteries: Compatibility with Olympus BLH-1, BLH-01 and PS-BLH1 battery types ensures cameras recognize the cells and report remaining power accurately.
• LCD AC charger: The included charger displays charging status and battery capacity so users can see progress and estimate runtime at a glance.
• Foldable flat pin: A foldable plug makes the charger easier to store and travel with, reducing bulk in a camera bag.
• Wide input range: Input AC 100~240V 50~60Hz supports international use without a separate adapter for many travel situations.
• Practical output: The charger delivers DC 8.4V at 800mA, providing steady charging for the included lithium-ion cells.
• Battery capacity: Each battery is 1750mAh at 7.4V, offering useful runtime as a spare for OM-D E-M1 series users.

Who It's For

Photographers who use Olympus OM-D E-M1 Mark II or OM-D E-M1X cameras and need multiple spare batteries for extended shoots will appreciate this 4-pack with a single convenient charger. The decoded batteries make them behave like originals in camera menus, and the LCD charger helps manage a set of cells across events or travel days.

Users who prefer single-battery charging at OEM speeds or who require branded manufacturer support may prefer original batteries and chargers. Likewise, casual shooters who rarely change batteries could find a smaller two-pack or single spare more economical.
