Chuanyu C292 MicroSDXC card reader (USB2.0)

I have several idle TF cards on hand, and I have always wanted to use them, but I haven't put them into practice. Until recently, I couldn't think of anything to buy with the 10 yuan threshold free coupon exchanged with Tmall's points, I suddenly remembered the lack of a card reader.

Multifunctional. The USB 3.0 card reader is far beyond the budget (mainly because it wants to use Tmall vouchers, so it only wants to buy a dozen yuan.), and it is also not very useful. After all, there is a hard disk drive that can be inserted into mainstream cards. I chose Chuanyu as my mini card reader, which was just used to replace the USB stick in the car, saving more space, although the USB stick didn't seem to be in my way.

Personally, I don't like to take such a small card reader or USB stick with me. It's not easy to plug and unplug it, which is why I want to replace the USB stick in the car. Usually, I copy a file, but I still use a large USB flash drive to help.

Anyway, I plan to store songs in the car. USB2.0 is enough. I just hope it is stable and durable. This aspect needs time to verify. The specific reading and writing speed is not interested in detailed measurement. Copy a 150M video to a 2G TF card, and the speed is only 4M. Copy the 548M Sorai Konomiya code into the 8G TF card. The first time, the speed fluctuates greatly, from more than 17M at the highest to 0 at the lowest. This card has been used in Hongmi 1 mobile phone before. There are many files formed on the mobile phone in it, which can be copied after formatting. The speed is stable at about 17M. It feels OK.

March 24, 2019: I went to replace the USB flash disk in the car today.

After the card reader is replaced, about two-thirds of the space is saved (actually there is no egg use). It is found that the indicator on the card reader is always on after the ignition is turned off. Is the USB port not powered off? Although this weak power consumption should not lead to battery power loss, I always feel that there is another power consumption device.
