Koah PRO DMW-BLF19 Two-Pack 2000 mAh Kit

This kit provides two rechargeable lithium-ion batteries rated at 7.2V and 2000 mAh for Panasonic LUMIX GH3, GH4 and GH5 cameras. A dual USB charger is included so both packs can be replenished from any USB power source. The cells are built with Japanese chemistry for reliable cycle life. Photographers needing extended shooting time without mains power will find the spare capacity useful.

Sustained shooting performance

Each battery delivers 7.2V and 2000 mAh, giving consistent voltage through long sessions rather than a brief burst. The dual charger replenishes both packs simultaneously from a single USB connection, reducing downtime between shoots. Japanese lithium-ion cells maintain stable output across repeated charge cycles. Users who swap packs continuously can keep working without waiting for a single cell to recover.

Build quality and daily handling

The two-pack bundle measures 8.4 x 6.2 x 4.7 inches and weighs 1 ounce, making it compact enough for a camera bag pocket. USB charging means the unit works with power banks, laptop ports or wall adapters already carried on location. Batteries are fully compatible with the original Panasonic charger as well as the supplied dock. Shooters who rely on proprietary docks or non-USB power sources gain no extra convenience from this kit.
