The DashDrive AE400 -
The ADATA AE400 is wireless media device that can take USB thumbdrives and SD cards as input media. From there it can send this to a mobile device (Android or iOS) using an App. The Wi-Fi is 802.11n but there is more to it than just an access point. The DashDrive Air AE400 is also a wireless bridge. This mean that you can connect your devices to the AE400 and then connect the AE400 to the internet.
It is not a large device but it is a little bulky (although certainly not the most bulky we have seen). It has a textured, honeycombed surface with a single power button on the top. This button is in the shape of the honeycombs, but is easy to find as it is a different color. In the middle of the AE4000 there is a small flat band that has activity lights. These lights are WiFi, Disc battery and the Wireless signal icon. These are enough to keep let you know what is going on.
Looking at the sides of the AE400 we see the charging port a USB 2.0 port and a small hole. That little hole is to reset the device. The USB port has a dual purpose; you can use it to charge your phone (the AE400 is a 5000 mAh battery) and also to plug in a USB thumbdrive. Both the USB drive and the SDCard need to be formatted in the right way (FAT32 or exFAT) or the DashDrive Air will not see them at all. Fortunately most media even large capacity media is formatted Fat32 simply for compatibility. Sadly this also limits the size of the file you can put on the media (less than 2GB file size). The number of users that can connect to the AE400 depends on what you are trying to do; if it is simple file/photo viewing or 720p video then the limit is 5 at 1080p you are stuck with only three users. In general it is a very solid little device with good options for media storage and playback.
