DSLRKIT USB Type-C to CR2450 Dummy Battery Power Kit

V3.0 Ultra-Wide Voltage Version (DC 3V–30V Input) with Over-Voltage 

Product Overview This DSLRKIT power extension kit provides a complete external power solution for devices originally powered by CR2450 coin-cell batteries. It combines a wide-voltage dummy battery adapter with a convenient USB power cable featuring an inline ON/OFF switch. This kit is ideal for fixed-mounted applications where frequent battery replacement is inconvenient, such as wall-mounted displays, wireless switches, remote controllers, monitoring modules, smart buttons, and long-running low-power electronic sensors

Key Features

• Complete Power Solution: Includes both the USB Type-C to CR2450 Dummy Battery Adapter and a dedicated USB to Type-C power cable with an integrated switch.
• Convenient Power Control: The included 1.2 m (3.9 ft) USB cable features an inline push-type ON/OFF switch. This allows you to easily turn off the connected device without unplugging the power source, reducing wear on connectors.
• Ultra-Wide Input & Over-Voltage Protection (V3.0 Upgrade): Supports a DC 3V–30V input range. The V3.0 PCB integrates a TVS (Transient Voltage Suppressor) diode to protect against voltage surges.
• Detachable Installation (V3.0 Upgrade): Features an exposed FPC connector, allowing the 8.5cm FFC cable to be detached and threaded through narrow gaps before reattachment.
• Precision Engineering: The dummy battery module is manufactured using an actual-dimension CR2450 metal housing with a smooth surface and correct curvature. This ensures reliable electrical contact and a perfect fit in standard battery compartments.
• Non-Destructive Installation: Connected via an ultra-thin 85 mm (3.35 in) exposed Flexible Flat Cable (FFC), allowing for routing through battery covers without modifying the device enclosure.
