K&F CONCEPT NP-W126S 1300mAh Battery and Dual Charger - Fast Type-C

In this review of the K&F CONCEPT NP-W126/NP-W126S battery and charger kit, the bottom line is simple: photographers who need reliable spare power for Fujifilm bodies will find a sensible, cost-effective option here. The package includes two 1300mAh replacement batteries and a dual-slot charger that accepts both Type-C and Micro-USB input, so the main reason to buy is dependable, decoded compatibility with a wide range of Fujifilm cameras and flexible charging options when traveling or shooting all day.

Key Features

• 1300mAh capacity: Each battery offers a higher-capacity cell that extends shooting time compared with many older NP-W126 cells, reducing mid-shoot battery swaps.
• Dual batteries included: The two-pack ensures a spare is ready in the bag so users can swap quickly during long sessions or travel without hunting for power.
• Fully decoded compatibility: The batteries are recognized by Fujifilm cameras such as the XM5, X100V, X100VI, XS10, XT30 and others, so there are no authentication pop-ups.
• Dual-slot fast charger: The charger takes two batteries at once and supports quicker turnaround when both cells need topping up between shoots.
• Type-C and Micro-USB inputs: Charging from a modern USB-C power adapter, car charger or older USB sources adds flexibility for studio and travel workflows.
• Built-in protections: Over-charge, over-current, over-discharge, over-voltage and short-circuit protections protect the batteries and camera from basic electrical faults.

Who It's For

The kit is best for Fujifilm photographers who use cameras powered by NP-W126/NP-W126S batteries and want a reliable set of spares with an easy, portable charging solution. Street, travel and event shooters who need an extra two batteries and the convenience of USB-C charging will appreciate that the pack comes decoded for Fujifilm bodies so it works without camera warnings.

This is less appropriate for users requiring OEM-branded service or the longest possible run time per battery; professionals who demand factory-specified endurance or want integrated battery meters in camera firmware might prefer official manufacturer batteries. Also, there is no bundled high-wattage adapter supplied, so expect to use your own 5V 2.1A or higher USB adapter for fastest charging.
