Bonus, it doubles up as external battery pack. 3,000mah may not be a lot but it does come in handy in those critical must have a charge situations.
Wireless wi-fi storage and external battery pack 3000mah
SD card slot
The size of the wifi disk is about the size of a portable hard drive. Slightly bigger than my S3; look at attached picture for reference.
To connect to the device you must make a wifi connection to it. It is named "WiFiSD-158E" and the password is "11111111". That is 8 ones BTW.
I was able to pick up a wide array of storage media. SD card, microsd in a sd card adapter, Flash drives ranging from 4gb to 32gb with many different brands. It was able to power a Seagate portable hard drive no problem while a SD card was also in the sd card slot.
Many different devices were used to connect to the wifi disk: Nexus 7, Nexus 10, Ipad 4, Acer laptop, Coby Cryos android tablet, galaxy S3, Iphone 5 and a t-mobile S2.
It says that up to 5 devices can be connected to it.
I was able to play all sorts of video files from it, divx/xvid, avi, mp4, mkv, mov.....720p,1080p. It handled it like a champ.
I connected 5 devices and tried to stream a divx file all at the same time. It worked flawlessly, no stutters, no audio drops.
Now I dunno about HD 720p or 1080p files with 5 devices trying to stream from it. Will try more tests later.
You can access your connected storage via 3 different ways:
Now, you can use the recommended mobile apps mobile fun (android) and airstor (IOS) to connect to the device to see your connected storage options. They are nice clean simple apps. Reminds me of an "ES Explorer" type file explorer. Pretty fast, smooth and it simply just works. The one thing the APP is a must for is to make it a wifi hotspot. What that means is that you can configure it to connect to your regular home internet router so that when your device is connected to it; you can still have internet access. Basically it acts like a wireless bridge for your router. Once configured you don't have to use the apps ever again.
You can even use your browser to go to "10.10.10.254" and connect via a web interface. The default username is "admin" and there is no password. You can configure it to have a password; which I did via a wizard tutorial. This is nice since you can connect your laptop to it and access the connected storage.
The last option was a little thing I figured out and was pleasantly surprised! The wifi disk can be accessed via ANY file explorer app that can make SAMBA/SMB connections! File explorers such as "ES Explorer" and "Solid Explorer" have this ability. I personally recommend solid explorer (more on that in a bit).
You just have to set it up (please see attached picture for reference).
For solid explorer press the "jump" button, then "Network" and then "SMB/CIFS" button. Jump>Network>SMB/CIFS
Now press the plus sign button at the top right. It will cause a popup that you will need to fill in the appropriate info.
Display name: can be left blank
Computer name or ip address: enter 10.10.10.254
Authentication method: can set as "Log in as guess" if you did not use the web interface to make a pass word. If you did make a password set it as "store encrypted password"
password: whatever password you made via the web interface
Now you should be able use the file explorer to navigate the connected storage options:
SDCARD-Volume1 = SD card slot
USBDisk-Volume1 = USB port connected storage
Now you don't need an extra app to use the wifi disk. Use the file explorer you love and know!
Solid Explorer is my reccomendation because it has the two pane option when in landscape mode. With the two panel mode, you can navigate to the "SD card" with pane 1 and then navigate to the "usb port" with pane 2. This will allow you to transfer files between the "sd card" and the "usb port" storage seemlessly and easily! There was a step by step guide on amazon how to transfer files between two attached storage options on the wifi disk, but this makes it sooooo much easier!
Build Quality: Seems solid, not too flimsy but quite light. Nice colored LED's that aren't too bright.
Gripes about it:
Only comes in white; no black option. It sticks out like a sore thumb next to all my other devices. The external battery pack I bought before Xmas had a white generic apple charger which didn't go with the black external battery pack I bought.
Does not come with a wall charger; but will use any usb charger.
I do not work for RAVpower but was really impressed with their external battery pack for Xmas. Was even contacted by them after the new year to personally ask how the product was working out for me. That was a pleasant surprise. So that pushed my try the wifi disk instead of bigger name alternatives.
