Powerextra 2 Pack DMW-BLG10 Battery and Dual USB Charger - Backup

In this review the Powerextra 2 Pack DMW-BLG10 battery kit is assessed as a practical backup power solution for owners of compatible Panasonic Lumix and DMC cameras. The bottom line: it is for photographers who need extra runtime and flexible charging on the go, because the package includes two 7.4V 1500mAh replacement batteries and a dual USB charger with an LCD that shows charge status. The reviewer found the kit delivers solid value, straightforward USB charging from wall or portable power, and noticeably longer runtime than many original batteries, though fit can vary by camera body.

Key Features

• Compatibility: Designed as a 100% compatible replacement for DMW-BLG10 batteries so it works with a broad range of Panasonic Lumix DC-G100, DC-GX9, DC-LX100 II and other listed models.
• Battery Capacity: Each Li-ion cell is rated 7.4V 1500mAh 11.1Wh, offering extended shooting time compared with older cells.
• Premium Cells: Uses premium Li-ion cells with no memory effect so batteries can be charged or discharged at any time without reducing long-term capacity.
• Dual USB Charger: Charger accepts 5V/2.1A input and outputs 7.4V/0.5A to each bay, enabling simultaneous charging of two batteries from a USB source.
• LCD Charge Display: Built-in LCD shows charging level for each bay so users can monitor progress without guessing.
• Versatile Charging: The included USB cable allows charging from wall adapters, car chargers, or external battery packs for portability.

Who It's For

This kit is best for hobbyist and travel photographers who need reliable backup power without carrying a bulky charger, and for anyone who favors charging from USB power banks while shooting away from mains power. The two-battery bundle plus a compact charger makes it easy to swap batteries quickly during long shoots or travel days.

Photographers who require guaranteed OEM fit or who use less common camera revisions should test compatibility carefully, as a few users reported fit issues with certain GX9 bodies. If exact factory-certified batteries are required for professional workflow, consider factory branded batteries instead.

Pros & Cons

Pros

• Two replacement 7.4V 1500mAh batteries provide substantial extra runtime compared with older batteries.
• Dual USB charger is convenient and charges both batteries simultaneously from any 5V USB source.
• LCD display clearly shows charge level for each bay so charging status is easy to track.

Cons

• Some customers reported mixed fit or capacity experience on specific camera bodies such as certain GX9 units, so compatibility is not universally flawless.
• Charging rate is modest at 0.5A per bay, so full recharge times are longer than high-current dedicated chargers.
