  • Clear LCD shows exact charge percentage and bar status
  • Dual slots charge two batteries at once, halving prep time
  • USB output powers phones and tablets while batteries charge
  • Universal 110-240V AC and optional 12-24V DC input works worldwide
  • Microprocessor auto-detects voltage and prevents overcharging

Dual-slot charger for DMW-BLJ31 batteries

The Green Extreme Dual Smart Charger powers two Panasonic DMW-BLJ31 batteries at once, halving the time needed to prepare for a shoot. An easy-to-read LCD screen shows real-time charge percentage and a bar indicator for each slot. A built-in microprocessor detects battery voltage automatically and applies intelligent charging to prevent overcharging. The Wake Up feature revives cells that have been excessively depleted.

Replaces single-slot and fixed-voltage chargers

Photographers who currently charge one battery at a time or carry separate chargers for different voltages gain a single unit that handles both tasks. The jump is worth it when you need two ready cells before leaving for a location or when you work with mixed battery types using optional adapter plates. Universal AC input from 110 to 240 V and optional DC input from 12 to 24 V remove the need for region-specific power supplies.

Handles two batteries

The charger comfortably manages dual DMW-BLJ31 cells while its side USB port powers a phone, tablet or power pack at the same time. Headroom extends to other voltages when the appropriate adapter plates are fitted, making one charger cover multiple camera systems. It runs out when more than two batteries must charge in parallel or when a device demands a proprietary charging protocol not supported by the USB output.

Questions about this item

What power sources can the Green Extreme Dual Smart Charger connect to for AC and DC input?

The charger accepts universal AC input from 110 to 240 volts and optional DC input from 12 to 24 volts, allowing use with standard wall outlets or vehicle power sockets worldwide.

How do you insert the Panasonic DMW-BLJ31 batteries into the dual slots, and what common mistake should be avoided?

Align each battery's contacts with the corresponding adapter plate in the dual slots and slide it in until it clicks; the common mistake is inserting a battery backwards, which prevents the microprocessor from detecting voltage and starting the charge cycle.

When should the LCD screen or charging microprocessor be checked or serviced to maintain accurate charge reporting?

If the LCD shows inconsistent percentage readings, fails to display the wake-up activation for deeply depleted batteries, or the microprocessor stops preventing overcharge, the unit should be inspected by a qualified technician to restore reliable operation.
