Frequently Asked Questions
Q: What devices are these Micro SD cards compatible with?
A: These CHUXIA Micro SD TF cards are compatible with a wide range of devices including Android smartphones, tablets, laptops, digital cameras, SLR cameras, action cameras, drones (UAVs), dashcams, security and monitoring cameras, Nintendo Switch, portable gaming consoles, smart speakers, robots, and other digital devices with a microSD or full-size SD slot (using the included adapter).
Q: Are these cards suitable for 4K video recording?
A: Yes. These cards are rated V30 (Video Speed Class 30), U3, and Class 10, which means they guarantee a minimum sustained write speed of 30 MB/s — the standard required for smooth 4K Ultra HD video recording. They are also A2-rated for fast app performance on Android devices.
Q: Why does the usable capacity appear slightly less than the advertised size?
A: This is a standard industry difference. Memory card manufacturers calculate 1 GB as 1,000,000,000 bytes, while most operating systems use 1,073,741,824 bytes per GB. This results in a small difference between the advertised size and what appears on your device — it is not a defect. For example, a 64GB card will show approximately 58–60 GB of usable space on your device.
Q: Do these cards come with SD adapters?
A: Yes! Each of the 10 cards in this pack includes a full-size SD adapter, so you can use the micro SD cards in devices that have standard SD card slots such as laptops and DSLR cameras — no additional purchases needed.
Q: How durable are these Micro SD cards?
A: These cards are built for durability. They are shockproof, IPX6 waterproof, temperature-resistant from –10°C to 80°C, X-ray resistant, and antimagnetic, making them suitable for use in demanding outdoor and professional environments.
