A problem: What's the easy way for the wife to transmit the video she just recorded on her iPhone to her husband's Android phone, or to transmit it to her in the opposite direction?
The following two may be the most easily thought of by ordinary people:
If there is an Internet connection, it is transferred through cloud storage: iPhone is uploaded to the online disk, and Android is synchronized (downloaded)
If there is no network, transfer through the computer: iPhone is transferred to the computer first, and Android is retrieved from the computer
The first method is to upload before downloading. The speed depends on the speed and stability of Wi Fi. Generally, I will consider doing this for files below 100MB. Larger files will waste time.
The second method is too troublesome. You need to prepare two data cables in advance and install iTunes on the computer. Most of the Chinese I met don't use iTunes very well.
What if the conditions are a little harsh, no network and no computer?
Is there any way to quickly transfer videos from Windows computers or Android phones to iPhones? And fast video transfer directly from iPhone to Windows and Android? yes!
Teach you a new move
Today's protagonist is the TransferJet, which is led by Toshiba and is called "Transmission Treasure" in Chinese. This is an ultra short distance wireless transmission technology, which can transfer files freely within 3cm.
We have obtained the adapters of Lightning, MicroUSB and standard USB, which are currently sold by Toshiba, for iPhone, Android phone and Windows laptop.
With it, iPhone can be friends with Android phones and Windows laptops - file transfer, no network connection, no Bluetooth. And the speed is "very fast". How fast is it? See below.
TransferJet is not plug and play. Before use, you need to install a companion app, which can also be understood as a driver. We are Download and install the official 、 and , the installation process is the same as installing ordinary software.
Android applications can also be downloaded from major third-party app stores in China. iOS applications are naturally App Stores. Windows software is recommended to be downloaded through the official website.
Looking at the figure above, you can see that the Android application of TransferJet is strange. It does not have a complete user interface. In terms of use logic, Android applications are also different from the other two platforms: directly opening an application is a pop-up window for "receiving" data; Send uses the system level sharing function.
Next, let's start the test: iPhone and Android phones, and iPhone and Windows computers transfer files to each other.
TransferJet sends and receives files
I used the iPhone 5s and Samsung Galaxy S6 edge for testing. For the scenario at the beginning of the article, just open the TransferJet application on iPhone, select "Send Picture/Video", find the corresponding file, and select "Send"; Open the application on the Samsung mobile phone to receive directly. (Pairing is required for the initial connection, and the process is simple, just click once more to confirm)
If the Samsung mobile phone is transferring files to iPhone, the operation mode is completely different: first find the file to be transferred on the Samsung mobile phone, then find "TransferJet" in the "Share" menu, then open the iPhone application and select "Receive".
The wireless transmission speed between the two is very fast, reaching the official 375Mb/s, which is equivalent to the USB 2.0 wired connection speed, with a theoretical value of 480 Mb/s.
However, it should be noted that the effective distance of the TransferJet is only 3cm. If you hold two mobile phones vertically normally, the distance will exceed. You need to tilt them slightly to make them close together or put them on the table.
Next, test the file transfer between iPhone and Windows computer. In fact, the software operation logic of the two platforms is the same: one selects to send, and the other selects to receive. There is no need to repeat.
If an Android phone is used to transfer files to a Windows computer, it also needs to use the system's "sharing" mechanism. After the transfer is completed, iPhone will prompt, and Android and Windows computers will automatically open the file just received by default.
We tested a 180MB file to be transferred between the three devices, and it took about 20s.
Restrictions
The adapter of TransferJet can be used only when the Android phone supports OTG function, and the operating system requires Android 4.0 or above. This requirement can not defeat most mobile phones on the market.
Windows XP systems cannot support it. Windows 7/8 or later systems are required.
IPhone only needs iOS 7.1 or above. In particular, iPhone can only send photos or videos in Photos and receive photos or videos in formats supported by Photos. Android and Windows have much looser restrictions on file formats, and there are basically no restrictions.
The standard USB and MicroUSB versions of the TransferJet adapter can be purchased at JD or Toshiba Tmall flagship stores for 158 yuan each. The version of the Apple Lightning interface has not been sold as of the release date. Toshiba staff told Lei Feng.com& Love to play computer games , TransferJet adapters that support TV and printer use have been mass produced and will be available soon.
summary
TransferJet is an attractive technology, especially in terms of speed and stability. But this technology is not convenient to use - device A chooses to send, and device B chooses to receive manually, which is unnecessary. You should know that people can send the troublesome Bluetooth transmission on one side and receive the "receive file" reminder on the other side. When I use it, I often choose to send it on one side and wait for the other side to get a reminder. Then I realize that it can't do it
For ordinary people, most of the time they don't have the power to spend 300 yuan to buy two adapters, which are only used to transfer photos and videos. But in some commercial and quasi commercial fields, Especially in the absence of Wi Fi or unstable network, the reliability and efficiency improvement of 300 yuan is worth considering.
If you need to transfer the iPhone screen to a TV or projector, it is recommended to buy an official Lightning to VGA or HDMI adapter, and give up those cool sounding methods to avoid embarrassing accidents when speaking on the stage. Stability and reliability are sometimes so important. TransferJet has this feature.

Attachment: What is TransferJet
TransferJet is a kind of near distance transmission technology jointly developed by Sony, Panasonic, Hitachi, Samsung Electronics and other international manufacturers in 2008. It mainly adopts the principle of inductive magnetic field, which means that two close devices can realize point-to-point high-speed data transmission. The transmission rate can reach 375Mbps in 560MHz band and 4.48GHz channel.
Toshiba TransferJet currently has Lightning MicroUSB and USB adapters must have two adapters for data transfer, and the adapter must be kept within 3cm.
