Kit Contents

This kit supplies two rechargeable 7.2V 2250mAh lithium-ion batteries and one compact dual USB-C charger with an LCD status screen. It is designed for photographers and videographers who use cameras accepting the Panasonic DMW-BLK22 battery and want a spare power solution for extended shoots.

Upgrade Path

The included batteries exceed the capacity of the original Panasonic DMW-BLK22, delivering longer run time per charge. The jump is worth it when a single OEM battery cannot cover a full day of stills or video recording, or when a second battery is needed to keep shooting while the first recharges.

Capacity and Headroom

Each 2250mAh cell provides extended operating time for compatible Panasonic cameras, and the dual charger replenishes both simultaneously from any 5V 2.1A USB-C source. The charger outputs 8V at 700mA or 500mA per slot. It is not suited for users who need higher voltage outputs or faster charge rates than the specified 700mA maximum.

Questions about this item

What charger input does the USB-C dual charger require?

The dual charger accepts 5V 2.1A input via its USB Type-C port, so any standard USB-C power source delivering that current will work.

How do I read the charge level on the LCD dual charger?

The charger's LCD screen shows the charge status for each battery slot independently, letting you see progress at a glance.

When should I expect to replace the 2250mAh batteries?

Premium Japanese lithium-ion cells resist memory effect, so capacity loss is gradual; plan on new cells when run time drops noticeably below the rated 7.2V 2250mAh.
