Dash Cam Storage

The THINKWARE 128GB MicroSD card is built for continuous video recording in dash cams. It stores Full HD footage and HD still images during extended drives. The UHS-I interface provides a minimum transfer speed of 10MB/s to keep write operations steady. A bundled TransFlash adapter allows use in standard SD slots.

Sustained Write Reliability

SPOR technology protects recorded files when power is lost suddenly during an incident. The card maintains the minimum 10MB/s write rate needed for uninterrupted Full HD capture. Continuous shooting and loop recording workloads stay stable without frame drops. File corruption risk is reduced even if the vehicle ignition cuts power mid-write.

Environmental Durability

The card operates reliably across a temperature range of -10 to 60 degrees Celsius. It is engineered to withstand water exposure, physical shock, and X-ray screening. No active cooling or moving parts mean completely silent operation. Power draw remains minimal, suited to the constant low-voltage supply of a dash cam.

Questions about this item

How much power does the 128GB MicroSD card draw when recording continuously in a dash cam all day?

The card itself draws negligible power from the dash cam slot; heat and noise are not factors for solid-state storage.

What adapter or device must I already have to use this MicroSD card in a standard SD card slot?

A TransFlash adapter is included in the package for use in full-size SD slots.

Will this UHS-I card work reliably in an older dash cam that only supports Class 10 speeds?

Yes, UHS-I is backward compatible with Class 10 devices and meets the 10MB/s minimum transfer speed required.
