Dual NP-F Battery Charger

The Kastar NP-F550/F570 LTD2 is a dual-slot charger designed for Sony NP-F series batteries used in professional camcorders and lighting gear. It accepts two batteries simultaneously and swaps charging plates to fit NP-F330 through NP-F970 packs. The unit draws power from any 5 V USB source via Micro-USB or USB-C connectors, making it suitable for location work with power banks or mains adapters.

Sustained Charging Behaviour

Each bay delivers a steady 8.4 V at 800 mA whether one or both slots are occupied, so total output remains within the 15 W input budget during extended sessions. The LCD panel shows real-time voltage and capacity percentage for each cell, letting operators monitor progress without interrupting the charge cycle. Heat stays low because the current is capped per channel rather than pushed in short bursts.

USB Power Limits

The charger requires a 5 V supply capable of 2 A to 3 A; lower-output ports will not start the cycle. Micro-USB and Type-C inputs are functionally identical, but neither supports Power Delivery negotiation, so the brick or bank must provide a fixed 5 V rail. A Micro-USB cable is included; USB-C cables are not.

Questions about this item

How loud or hot does the Kastar NP-F550/F570 LTD2 USB Dual Charger get when charging two batteries continuously?

The charger runs silently with no fan; only the LCD backlight and indicator LEDs generate negligible heat during dual 800 mA charging.

What power source and cable must I already own to run this charger?

You need any 5 V 2–3 A USB supply (15 W) and either a Micro-USB or USB-C cable; one Micro-USB cable is included.

Will the charger recognise and charge older NP-F330 or NP-F550 packs alongside newer NP-F970 batteries?

Yes — the interchangeable plate supports the full NP-F series from NP-F330 through NP-F970, so legacy and current packs charge together.
