Xinggang Electronics solemnly promises: All memory cards sold are genuine and of full capacity!!

It is recommended to use the disk software H2testw for detection to reveal the true nature of the expansion card (upgrade card)!

Test whether the memory card has sufficient capacity?

Method One:

使用H2testw进行测试。

For the installation of H2testw, please consult customer service

Method Two

A simple method, such as testing 4G, can store over 3G of music. If all of it can be read normally, it indicates that it is a full-capacity card. If it is an expansion card, only the files stored at the front end can be read, while the files at the back end are damaged and cannot be read.

Warm reminder: Due to the significant fluctuations in chip prices, all customer service inquiries are based on the real-time quotations of the day and are for reference only in the future.

The TF card (small card) is different from the SD card (large card). The TF card is approximately one fourth the size of the SD card and is currently the smallest memory card in circulation. It is suitable for devices such as mobile phones, drones, robots, dash cams, car navigation systems, card slot speakers, learning machines, voice recorders, cameras, and surveillance cameras. TF cards have the advantages of traditional SD cards. When paired with SD adapter card sleeves, they can be converted into SD cards and are compatible with devices that use SD cards, meeting the SD specification standards.

The label of this product indicates the memory capacity it is equipped with, not the actual usable storage capacity.

 A storage capacity of 1MB is calculated as 1,048,576 bytes. A portion of the storage capacity is used as the management area, so the available storage capacity is as described above.
