Kastar NP-FW50 4-Pack with LTD2 Dual Charger

This set supplies four 7.2 V 1650 mAh lithium-ion batteries and a dual-slot USB charger for Sony mirrorless and Cyber-shot cameras. Each cell delivers 11.8 Wh of capacity. The package suits photographers who need several spares for long shooting sessions.

Charger limited to 5 V USB input

The LTD2 accepts Micro-USB or Type-C power at 5 V 2–3 A (15 W) and charges two batteries simultaneously at 800 mA each. It cannot operate from a dedicated AC adapter or a higher-voltage DC source. Users without a suitable USB power supply will need to provide one separately.

1650 mAh capacity per battery determines runtime

Each NP-FW50 replacement stores 1650 mAh at 7.2 V, giving 11.8 Wh per cell. This figure decides how many shots or video minutes you gain per charge compared with the original Sony pack. Buyers who need significantly more energy per battery will find this capacity insufficient.

Questions about this item

Should I buy the 4-pack or would a smaller pack be enough?

This pack contains exactly four 1650 mAh NP-FW50 batteries and one dual-slot charger; no other pack sizes are offered in this listing.

What does the 11.8 Wh rating mean for actual shooting time?

Each 7.2 V 1650 mAh cell stores 11.8 Wh, giving a full charge equivalent to the original Sony NP-FW50 in compatible Alpha and Cyber-shot bodies.

How fast does the LTD2 charger fill a battery over USB-C?

The charger delivers 8.4 V at 800 mA per slot, so one battery takes roughly two hours and two batteries charge simultaneously in the same time.
