DMW-BLK22 Replacement USB-C Battery 2 Pack - Fast Type C Charging

In this review the focus is practical: the DMW-BLK22 replacement USB-C battery 2 pack is aimed at photographers who need reliable spare power for a range of Panasonic Lumix bodies. The single biggest reason to consider these cells is the combination of a higher capacity 2600mAh rating and built-in USB-C fast charging, which removes the need for a separate charger and makes topping up on location quick and convenient. The review covers fit, charging behavior, indicator accuracy, and safety features observed during routine use.

Key Features

• Wide compatibility: Works with many Panasonic Lumix models including S9, S5 series, S1R, GH and G9M2 series, so photographers with multiple bodies can use the same spare batteries.
• USB-C direct charging: The included USB-C cable allows charging from USB adapters, car chargers, and power banks, reducing the need to carry a separate charger on shoots.
• Higher capacity: The 2600mAh high-density cells exceed the original capacity, which translates to longer shooting time between charges for most users.
• LED indicator: An intelligent LED percentage display is revealed by pressing the PUSH button, making it easy to check remaining charge without powering the camera.
• Built-in protections: Overvoltage, overcurrent and overheating safeguards are provided to protect camera electronics and reduce risks of bulging or leakage.

Who It's For

The battery set is best for enthusiast and professional photographers who shoot on location and need extra runtime without carrying a bulky charger; the USB-C fast charging is particularly useful for travel, event work, and field shoots where power banks are used. The higher 2600mAh capacity is helpful for long days or when using power-hungry settings like video or high-frame-rate burst shooting.

Those who should look elsewhere are photographers requiring original-manufacturer batteries for warranty reasons or those who need integrated charger docks and prefer rapid multi-battery charging stations; this product charges batteries one at a time via USB-C.

Pros & Cons

Pros

• Higher-than-original capacity provides noticeably longer runtime in both stills and video use.
• USB-C direct charging eliminates the need for a separate charger and works with common power sources.
• LED percentage indicator gives a clear, on-demand readout of remaining charge.
• Multiple safety protections reduce the chance of charging-related faults.

Cons

• Charges via USB-C only, so users needing simultaneous multi-battery charging will need a separate solution.
• As a compatible replacement, some users may prefer branded OEM batteries for warranty or brand assurance.
