SmallRig 5487 Turbo Charging Kit for DMW-BLK22 Camera Batteries

SmallRig 5487 Turbo Charging Kit for DMW-BLK22 – Dual fast charger with two 1940mAh batteries

The SmallRig 5487 Turbo Charging Kit includes two high-performance replacement batteries and a dual-channel fast charger designed for Panasonic DMW-BLK22 cameras. It provides reliable power for extended shooting and supports in-camera battery monitoring thanks to a full decoding chip. The kit also preserves compatibility with original chargers and avoids camera pop-up warnings.

What this kit contains

• Camera battery charger for DMW-BLK22
• 2 × camera batteries for DMW-BLK22 (true-rated output 1940mAh each)
• 2 × battery covers
• 60W USB-C to USB-C cable (1 m)

Fast charging and charging behavior

The dual-slot charger charges two batteries simultaneously and can also charge a single battery on its own. Under optimal conditions, it fully charges two batteries in approximately 2 hours for efficient turnaround between shoots.

When you connect a lower-output adapter (for example a 5V / 2.4A adapter), the charger switches to a slow-charge mode. In that mode, Channel 1 receives priority and will charge first; Channel 2 begins charging automatically once Channel 1 is fully charged.

Intelligent safety and battery care

The charger uses intelligent circuitry to protect both the batteries and your gear. It continuously monitors temperature and voltage, and it responds automatically:

• It slows charging if the battery overheats.
• It cuts off power if an overvoltage condition occurs.
• It switches to trickle charging as the battery nears full capacity to help preserve long-term battery health.

Indicators and warnings

Each charging channel features five LED indicators that show power levels in 20% increments. The LEDs operate even without external power, so you can check battery level at a glance. Additionally, a red warning light activates when battery levels are critically low.

Flexible power options

The charger includes a universal USB-C input and comes with a fast-charging USB-C to USB-C cable. Therefore, you can power the charger from a variety of sources such as wall adapters, car chargers, and power banks. For best performance, SmallRig recommends using a power adapter with 22.5W or higher output.

FAQ

Question: How long does it take to charge the batteries?
Answer: Under recommended conditions the dual-slot charger fully charges two batteries in approximately 2 hours. Using a lower-output adapter (for example 5V / 2.4A) switches the unit to slow-charge mode and extends charging time.

Question: Will my camera recognize these batteries and show remaining power?
Answer: Yes. The kit uses a full decoding chip to ensure compatibility with Panasonic DMW-BLK22 batteries. This eliminates pop-up warnings and supports in-camera power display as well as use with the original charger.

Question: What safety features protect the batteries while charging?
Answer: The charger monitors temperature and voltage continuously. It slows charging during overheating, cuts off power in case of overvoltage, and applies trickle charging near full capacity to preserve battery health.

Question: Can I charge from a power bank or car charger?
Answer: Yes. The charger accepts a universal USB-C input and comes with a 60W USB-C to USB-C cable, making it compatible with wall adapters, car chargers, and power banks. For best results, use an adapter with 22.5W or higher output.

Question: How can I tell the battery level when charging or on the go?
Answer: Each charging channel has five LED indicators that display power in 20% increments. These LEDs work even without external power. Additionally, a red warning light alerts you when battery levels are critically low.
