Product information

Description

SmallRig NP-FW50 Camera Battery and Charger Kit 3818 includes two lithium-ion batteries and a dual-slot charger compatible with cameras using the NP-FW50 form factor. Each battery features a full decoding chip to ensure proper communication with compatible cameras without pop-up warnings. The battery casing is made from fire-resistant ABS and PC with a frosted finish; the cells and overall dimensions match original NP-FW50 batteries so they fit standard camera compartments. The charger accepts USB-C input and has a built-in USB-A charging cable for flexible powering options.

Advantages

The kit provides two spare batteries plus a dual battery charger that can charge both batteries simultaneously. An LCD screen on the charger shows real-time charging voltage, current and charged capacity, improving monitoring during charging. The charger’s USB-C input and integrated USB-A cable allow charging from a USB adapter, car charger or power bank. The batteries’ full decoding chip and original-size design help ensure reliable compatibility with cameras that use NP-FW50 batteries.

Suitable for

Mirrorless and compact cameras that use NP-FW50-type batteries
On-location shoots requiring spare batteries and simultaneous charging
