Kastar NP-FM500H 4-Battery Kit

This kit supplies four 7.4 V lithium-ion batteries rated at 2400 mAh each and a matching AC wall charger. It targets photographers using compatible Sony Alpha and SLT bodies who need reliable spares for long shooting days. The foldable flat plug makes the charger easy to pack in a gear bag.

Capacity and charging limits

Each cell stores 17.76 Wh, giving enough capacity for several hundred frames on a typical body. The charger delivers 8.4 V at 600 mA, so a fully depleted pack reaches full charge in roughly four hours. Users who need faster turnaround or higher capacity cells will find the output fixed and the chemistry limited to standard Li-Ion.

Build integration and trade-offs

The charger accepts 100–240 V input, allowing worldwide use without a separate adapter. Its foldable pins reduce bulk, but the unit only charges one battery at a time, so rotating four cells requires sequential cycles. No car adapter or USB power option is included, limiting mobile charging flexibility.
