Kastar NP-FV50 LTD2 dual USB charger

The Kastar NP-FV50 LTD2 is a USB-powered dual charger for Sony NP-FV series lithium-ion batteries. It accepts two batteries simultaneously and swaps charging plates to fit NP-FV50, NP-FV70, NP-FV70A and NP-FV100 packs. The unit suits videographers and photographers who need to replenish multiple camcorder batteries from a single USB source.

Thermals noise and power draw

The charger draws up to 15 W from a 5 V 2-3 A USB supply and delivers 8.4 V at 800 mA per slot whether one or two batteries are inserted. No active cooling is fitted so operation stays silent and surface temperature remains low during normal charging cycles. An integrated LCD panel shows real-time capacity and charging status for each bay.

Deciding specification — interchangeable plates

The defining feature is the interchangeable plate system that lets one charger handle every NP-FV50, NP-FV70, NP-FV70A and NP-FV100 battery used across dozens of Sony Handycam, FDR-AX and HDR-CX models. Buyers who need to charge larger V-mount or Gold-mount blocks cannot use this unit.

Questions about this item

How do I set up the charger and what is the step people often miss?

Connect the Micro-USB or Type-C cable to a 5 V 2-3 A power source, insert one or two NP-FV series batteries, and ensure the swappable plate matches the battery model.

What maintenance or replacement will this charger need over time?

The Micro-USB and Type-C ports can wear from repeated plugging; the swappable charging plate may loosen, and the LCD status display can dim after extended use.

Which limit appears first when charging continuously?

The 15 W input ceiling caps the total power draw, so with two batteries the 800 mA per channel rate cannot be exceeded.
