Promaster OM System BLX-1 with USB-C Charging (7.2V/2250M)

Upgrade your shooting experience with the ProMaster 2,250 mAh USB-C rechargeable battery, designed for cameras that use the OM System BLX-1 battery. With an integrated USB-C charging port, this might be the most convenient camera battery ever made—no more bulky chargers or downtime while your camera is tied up.

Convenient Built-In USB-C Charging

Simply connect any USB-C cable (a USB-C to USB-A cord is included) and watch the on-board LED charging light switch from red to green when your battery is fully charged. This battery works with a wide range of USB power sources, from as little as 0.5A (up to 3.0A), making it perfect for home, studio, or travel.

Faster Workflow, Greater Freedom

In-camera charging can leave your camera stuck for hours, and carrying an external charger adds bulk to your kit. With the ProMaster BLX-1 battery, you get the best of both worlds: charge externally without tying up your camera, and without needing an extra charger. Just plug in a USB-C cable and power up anywhere.

Complete with Protective Case

Each battery includes a protective storage case that keeps your gear safe and organized. The case holds the battery plus the included cable—or swap the cord for a second battery. This ensures your battery stays clean, with contacts protected from accidental damage or shorts during transport.

Reliable Power & Built-In Safety

ProMaster uses only the highest-grade lithium-ion cells for long life and consistent performance. Multiple layers of protection are built in, including:

• Overcharge & over-discharge protection

• Overcurrent protection

• Overvoltage regulation

From fully depleted to 100%, charging takes approximately 4.5 hours with a 0.95A minimum current.
