Frequently Asked Questions

Q: Is this Micro SD card compatible with my Android smartphone?

A: Yes! The CHUXIA Micro SD card is compatible with the vast majority of Android smartphones and tablets that support microSDHC (up to 32GB) or microSDXC (64GB and above) formats. The A2 rating also makes it excellent for use as adoptable/extended storage for running apps directly from the card on supported Android devices.

Q: Can I use this card in my dash cam or home security camera?

A: Absolutely. This card is specifically designed for high-endurance video monitoring applications. Its Class 10, U3, and V30 ratings ensure it can handle continuous Full HD recording in dash cams and home monitoring systems. It is also built to withstand temperature extremes and shock, making it well-suited for in-vehicle or outdoor use.

Q: Why does my device show less storage than the labeled capacity?

A: This is completely normal and occurs because storage manufacturers calculate capacity using base-10 (1GB = 1,000,000,000 bytes), while operating systems display capacity using base-2 (1GB = 1,073,741,824 bytes). For example, a 128GB card will display approximately 115–119 GB available on your device. No storage is lost — it is simply a difference in how capacity is measured and displayed.

Q: What sizes does this Micro SD card come in?

A: The CHUXIA Micro SD card is available in 16GB, 32GB, 64GB, 128GB, and 256GB capacities. Choose the size that best suits your storage needs — from everyday phone use to large-scale video and file storage on cameras, drones, and gaming devices.
