What are the most unsatisfactory aspects of your smartphone? Some people say that small memory runs slowly, some people say that small screen operations are inconvenient, and others say that the appearance is not beautiful enough or even the system is not used to. But none of this is a problem. After all, it can make you use it normally. The author believes that the most anti human design of smart phones is 16G mobile phone storage space. With continuous updating, Android system is becoming larger and larger, and the percentage of the system in the mobile phone memory space is increasing.
The most annoying thing for the author is that he wants to install a software. The mobile phone prompts that there is not enough memory, and he needs to take a picture, which prompts that there is no storage space, let alone put some movies, music, and so on. It is uncomfortable to think about the impatient mood that cannot be copied.
Although there is a mobile phone USB flash drive at present, the insertion method will make the phone feel uncomfortable after all. The DM smart phone wireless USB flash drive is a mobile phone USB flash drive device that can realize wireless connection, and it also supports multiple people to use it at the same time. The outer packaging of the product is made of black environmental protection paper, and there is no redundant design on the front except for the DM mark on the bottom.
The back of the package is the basic parameter information of the product. The DM mobile phone USB flash drive I experienced this time has a capacity of 32GB. Of course, in addition to this capacity, the product also provides a choice of 16G/64G capacity, which can be used according to the user's personal needs. However, because the author has been fed up with 16G capacity, the psychological starting capacity of the author is 32GB.
The accessories provided by the DM wireless USB stick are very simple, including only one data cable.
The use of DM smart phone wireless USB stick is relatively simple. However, for the first time, users are advised to read the product manual. After all, it involves switch on/off and network switching.
In terms of power supply, MicroUSB power supply is adopted for the mobile phone USB flash drive, which is powered by 1400mAh lithium battery.
The size of the USB flash drive is not small, which is understandable. After all, the USB flash drive has a 2.4G/5G dual band function, so it is not easy to be too small. The size of the mobile phone USB flash drive is 62 * 62 * 10.5, which is slightly thicker than the Xiaomi 4i mobile phone.
The USB flash drive of the mobile phone is designed in white. The upper left corner is the power supply and switch button, and the lower right corner is the sign of DM. The author especially likes the slogan "I am afraid of myself when I run".
The back of the product is the basic technical parameters and product certification.
Press and hold the key for three seconds, the blue indicator light of the product is always on when starting up. The blue indicator light means that 2.4G is switched on wirelessly. Press and hold the key twice to switch to 5G status. At this time, the green indicator light is always on. The mobile phone USB flash drive has the function of automatically recording the frequency band. The next time you start up, it will enter the frequency band when you turn off by default.
The charging current of the USB flash drive of the mobile phone is 600~800mA, and the battery capacity is 1400mAh. The red LED flashes when charging, and the red light is always on when the phone is fully charged. However, according to the author's personal usage habits and the charging status of most devices, the green light is usually used to indicate when the phone is fully charged, which should be considered by the manufacturer. The charging time is about 2~3 hours, and the continuous video playing time can reach 6 hours, which can fully meet the needs of daily use.
DM smart phone wireless USB flash drive can be directly used as a USB flash drive after being connected to the computer. However, after the author's actual measurement, the writing speed is within 6MB, which is really slow. It is recommended that the manufacturer consider using USB3.0 high-speed interface design for subsequent products. After all, the copy speed is too slow and the copy time is too long. In order to better experience the product functions, a good APP experience is still necessary. The first time you use a wireless USB flash drive, there is no password. You can set a password when you connect to the APP. The 2.4G and 5G passwords are the same by default. By default, the SSID uses _5G as the 2.4G and 5G signals.
Through the setting, the DM wireless USB stick can be connected to the external network as a routing relay, which is mainly for the convenience of users connecting to the wireless USB stick to access the Internet. At the same time, this function also provides convenience for the later function upgrade, such as realizing the drama tracking function that everyone likes very much.
This time, the author has experienced a 32G wireless USB stick. In addition to online reading, the data such as files in the phone can also be uploaded to the DM wireless USB stick. For the convenience of users, it also provides the automatic backup function of address book and photo album. However, it is recommended to use this function with caution. Once the wireless USB flash disk is lost, your private photos and personal address book will be completely exposed.
The DM smart phone wireless USB stick can observe all files in the USB stick through the directory. The wireless USB stick has four functions, including video, music, pictures and documents online reading. Through video playback, the online playback speed is very fluent. For users who like to chase dramas, they can download the wireless USB stick in advance, which is very convenient to enjoy on the way to work or on business trips. The DM wireless USB flash drive supports a wide range of video formats. It can perfectly support 13 common video formats, such as MP4, mov, and mkv. Later updates to the episode tracking and downloading function will have more available space.
Picture function, it should be said that the manufacturer is considering the picture playing function, which is convenient for users to enjoy their own beautiful photos at any time. However, because the mobile phone may involve a large number of personal privacy photos, and the DM smart phone wireless USB flash drive is not really confidential at present, so once lost, the loss will be very large, so the picture function, I have to use it as a temporary storage of ordinary pictures.
The music playing function is one of the author's favorite functions, but the current audio support format is relatively small, only supporting mp3, wav and m4a audio formats. For the flac that I like very much, ape does not support it. I hope to support these lossless audio formats in the future. Of course, if you want to put it into your mobile phone, you can also download it easily.
The document function itself should be said to be a good function, which can realize online reading, but because there is no bookmark and other functions, the author does not like it very much. Of course, it also supports common document formats such as doc, xls, pdf, etc.
Unsupported formats can also be opened through the phone's own APP. Of course, this speed is not as comfortable as playing music and videos online. After all, data needs to be loaded in advance.
Summary
The DM smart phone wireless USB flash drive has a 2.4G/5G dual band transmission mode, which can easily switch between 2.4G and 5G by using keys. By setting a router connected to the home, the wireless signal can be expanded. Through APP, you can easily enjoy music, chase dramas and read novels. Of course, since the 2.4G and 5G of the wireless USB stick are transmitted separately, it is recommended to set up the network connection in advance for ease of use. In the later stage, if you can update the download function of chase drama, there will be more space for use. However, the author expects to implement encryption function through firmware update, otherwise the photo and address book synchronization function will not be used by the author anyway.
