- GH7 Compatibility
- DMW-BLK22 incl. GH7
Two 2250mAh cells and a dual USB-C charger arrive as a ready-made power kit for Panasonic DMW-BLK22 cameras, including the GH7. The charger tops both batteries at once from a 5V/2100mA USB-C source, which is enough to turn a small power bank into a field charging station. The cells are 7.2V Lithium-ion Grade-A, with runtime that tracks close to Panasonic's own BLK22 across typical shooting sessions. For a GH7 owner, this covers the first essential accessory, spare power, without forcing a choice between aftermarket cost and OEM performance.
Charging is not built into the batteries themselves, so the included dock is the primary way to top up a cell. That dock is compact enough to live in a camera bag, and the simultaneous dual-slot design means a spare is usually ready while the other cell is in the body. The cells have handled sustained 4K 60/120 capture without power loss, which points to enough headroom for demanding video work. They also hold up through long stills sessions, making this a practical pairing for hybrid shooters who switch between photo and video on the GH7.
This kit is for GH7 owners who need spare batteries and a charger now, want broad DMW-BLK22 compatibility across multiple Panasonic bodies, and prioritize cost per charge over OEM-grade certainty. Buyers who require absolute OEM-grade charge retention in every cell should treat that as a separate buying criterion; the value here is in the complete package, not in matching the Panasonic battery's exact charge curve. That makes this a stronger first purchase than adding individual cells as the need appears.
Charging speed depends on the power source. With a 5V/2100mA adapter, the dual USB-C charger refills both cells quickly; a weaker phone adapter will slow the process. The practical takeaway is that the kit plays well with a USB-C power bank, so GH7 owners can recharge two spares in a hotel room or vehicle without carrying a dedicated charger block. If you already own DMW-BLK22 cells, the charger also works as a second docking point, but the value of the kit is in having two fresh cells ready from day one.
💡 Feed the charger with a 5V/2100mA USB-C source; weaker adapters will stretch charge times.
Pros
- Two 2250mAh cells deliver near-OEM runtime at a fraction of Panasonic-brand prices.
- Dual USB-C charger tops both batteries simultaneously from a 5V/2100mA source.
- DMW-BLK22 compatibility covers GH7 and other Panasonic bodies using the same cell.
- Grade-A cells have handled sustained 4K 60/120 capture without power loss.
Cons
- The cells lack built-in USB-C charging, so the included dock is the only way to top them up.
- Battery life can vary between units; an occasional cell may hold less charge than a Panasonic OEM battery.
For GH7 owners starting from zero, this kit is the most direct path to spare power without OEM pricing, and the dual charger keeps both cells ready.
