Wide Voltage Version (DC 3V–12V Input)
Product Overview The DSLRKIT USB Type-C to CR2032 Dummy Battery Adapter provides a continuous external power source for devices originally powered by CR2032 coin cells. It eliminates the need for frequent battery replacements, making it an ideal solution for fixed-mounted applications such as wall-mounted thermometers, wireless buttons, remote control modules, and standby-powered smart sensors.
Key Features
Wide Input Range: Supports a wide DC 3V–12V input range, allowing compatibility with common USB Type-C chargers, USB power outlets, power banks, 12V power adapters, and similar power sources.
Precision Engineering: The dummy battery is manufactured using an actual-dimension CR2032 metal housing. Unlike low-grade alternatives that rely on soldered wires or irregular flat shells, this design mimics the correct thickness, edge curvature, and polarity surfaces of a real battery. This ensures a tight fit into standard battery trays and reliable electrical contact.
Non-Destructive Installation: The adapter and dummy battery module are connected via a high-quality 7cm Flexible Flat Cable (FFC). This ultra-thin cable allows for routing through battery covers without the need to cut or modify your device's enclosure.
Stable Output: The internal regulator delivers a stable DC 3V output, equivalent to a fresh CR2032 cell under normal load.
