Dual USB charger for Sony NP-FM series

The Kastar NP-FM50 LTD2 accepts two compatible Li-Ion batteries simultaneously and draws power from either a Micro-USB or USB-C source. It targets videographers and photographers who use legacy Sony Handycam or Cyber-shot models and want a compact way to keep spare packs topped up without a proprietary wall adapter. The charger ships with a Micro-USB cable and relies on any 5 V 2–3 A USB supply.

Installation and common issues

Simply insert each battery into its slot and connect the charger to a USB power source; no drivers or configuration are required. The LCD shows individual capacity and charging status so you can confirm contact is good. A frequent problem is using a low-current USB port that cannot deliver the rated 2–3 A, which stalls the charge or causes the display to flicker. Swapping to a higher-output adapter or powered hub usually resolves it.

Behaviour under sustained load

When both bays are occupied the charger maintains 800 mA per channel continuously, so total output stays within the 15 W input envelope. The intelligent controller regulates current to prevent overheating during extended sessions, and the LCD updates in real time as cells approach full capacity. There is no fan, so the unit relies on passive cooling; prolonged dual-bay operation in a warm environment may slow the charge rate slightly as thermal protection engages.

Questions about this item

How can I confirm the Kastar NP-FM50 LTD2 is charging both batteries correctly after plugging it in?

The intelligent LED display shows real-time charging status and battery capacity for each slot so you can see both batteries progressing simultaneously.

What comes in the box with the Kastar NP-FM50 LTD2 and what must I supply myself?

The pack includes one dual charger unit and a Micro-USB cable; you need to provide a 5V 2-3A USB power source and the NP-FM series batteries you want to charge.

Which version of the Kastar NP-FM50 LTD2 should I choose for my Sony DCR-TRV330 camcorder?

This single model accepts interchangeable plates that support NP-FM50, NP-FM55H, NP-FM70, NP-FM90 and related batteries used by the DCR-TRV330, so no separate version is required.
