Question: Will this work with an ipad air?  Can it be used to play movies on a portable USB flash drive?  What formats does it play?
Document: This feature worked seamlessly on my router with UVerse. *The EZOPower can also mount a USB key, which I find to be a much more useful feature than mounting an SD card. This feature worked great. *File transfers work well, and the app interface is decent enough. *The EZOPower can be used to power your devices as a backup battery - nice feature.Downsides:* I was not able to mount an external hard-drive.
Easy and fast way to transfer pictures from my Nikon D100 compact flash card to my phone and tablet. The D100 is too old for eye-fi technology. However, I needed a way to transfer from my camera while on the road. I plug a Transcend 3.0 USB reader into the EZOPower Portable, and the wireless download to my phone and/or tablet is very fast.
Iought this for a long trip in the car. All the kids have access to apple devices. I bought the SanDisk Cruzer Fit 32 GB x2 = 64GB USB Flash Drives and copied tons of movies to them, downloaded the app for each device and viola', all the kids got the pick of their own movies for 20 hours in the car. Battery life seems good although I didn't time it.
Airstor software seems to work adequately, for my needs at least. It's not perfect but I'm sure there will be upgrades with added functionality as time passes. So far, I've used it for files, pictures, and movies without issue. Streaming is fast with no lag. 10 hours advertised battery time seems to be about right. I'm sure it will vary some but I haven't had any issues with it yet.
It was described as &#34;The multifunctional, portable and user-friendly device allows you to wirelessly transfer photos, music, movies and other files from an SD card and USB storage device to iOS, Android and Windows smartphones/tablets&#34;... well not true NO downloadable application available for windows smartphones ..
We have now used tis with old Droid phones, Nook HD, and a Mini iPad. It sends out a good WiFi signal and the battery has lasted several downloads from the mobiles. It was shipped fast and packed well. I do hope the software apps get updates and advanced set of file management tools. You may want to look at the apps before buying. I will be trying other software with it to see how they work. I would buy this again as it does work.
It can transfer files from wireless reader to ipad air but stored in airstor application not in ipad air directory. Music and video files are working well and can be lsitening wirelessly.Office files and pdf file can be read but need to figure out how to modify it. Also need to figure out how to transfer files from ipad air to wireless reader.
I love that it can power my external hard drive! I connected 3 devices to this thing and it streamed hd movies to all devices without any issues.
The instructions are not geared for the technically illiterate,  but if you know what you are doing it is pretty simple to use. This little box has kept me from having to carry a laptop or portable hard drive, so I have no complaints at all.
This is pretty basic interface design FAIL on top of a perfectly good product.UPDATE: The SanDisk Wireless Flash Drive I now own has an actually *good* interface, showing 24 thumnails per page without any space between them except a very thin white line on all sides. It's a bit slow to open large folders but nowhere near as slow as the EZOPower app, and crucially, it takes this time generating thumbnails only *once* and then it can reopen a folder immediately!
Answer: Yes, it works with ipad air but you have to install "airstor" apps. I only tried mp4 video file. Mp3 music can be played too. Both files can be played remotely.
