Recently purchased the Ravpower RP-WD01 Wireless WiFi-Disk. It is probably the best investment I have made for ALL my mobile devices. I was on the fence about what wireless wifi storage to get Seagate, Kingston Wi-drive, Airstash and lots more but decided on the ravpower. Main reason was that it had a SD card slot and USB port to connect a multitude of different storage devices. And lets be honest, how many SD cards, microsd cards, portable hard drives and usb flash drives do we have laying around? There is soooo much potential with this product and some very nice surprises that I found out that makes this wifi disk a MUST have for all the tech geeks in us. 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. 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.
really no different then just using your device itself. streamed to the laptop or whatever your doing. mobile phones can handle up to 8 devices. they also act as a wifi. i can print wirelessly from my laptop to my printer using the phone's hotspot. there are also apps you can install for free. that allow you to use your wifi hotspot phone as a ftp server. or whatever the case may be. you can download any file from your phone to your laptop. wirelessly. buying a wifi device isn't the only option. but for those not to tech savy. probably worth the additional cost. i didn't see you mentioning a price though.
Yeah if you can use your phones hotspot etc you could just setup a network within your truck and if you want to stream music from your computer to your phone ton your stereo then there you go. Although probably also set up a modem so you don't have to worry about an outside connection.
