The Kingston MobileLite Wireless is a multi-purpose device. It's a wireless video streamer, so it's designed to stream to portable devices like phones and tablets. It is a wireless card reader, so it has an SD card reader as well as a wireless USB reader for aforementioned mobile devices. And finally, it is a backup battery, although I really feel the first two are the ones where it really shows its strength, whereas that third one is not a strong point for it. It has an 1850 mAh battery for both itself, for its own functionality, and to charge an attached device. So it's more like something you'd use in an emergency, as opposed to something where you'd have your phone tethered to it while you wirelessly stream something to yourself and expect to sit and watch movies like that. Overall, the device is a little bit on the larger side than I would have liked, but it still feels quite light, and whether that to you is more like an, oh, it feels kind of cheap, or whether you prefer to have things be lightweight, I like it when things have a little bit of heft to them. But the good news is that my initial impression of, oh, it feels kind of light and inexpensive, was correct. It is relatively inexpensive. For 50 bucks, Kingston is giving you a platform with which to use your own storage in order to stream things wirelessly, as opposed to most of the devices like this on the market that include storage and are therefore much more expensive. So you can just use existing USB drives and SD cards that you have lying around, which is definitely a plus. Also, my experience continued to be positive once I fired up the app downloads. So you can see I've got it running on a variety of platforms here, everything from an iOS tablet down to a couple of Android smartphones, and the ratings of the app, in addition to my experience, seem to reinforce that overall it's pretty darn good. It doesn't have a lot of functionality. And many of the mediocre ratings for the app are less to do with, it didn't work, it sucks, and more to do with, here's some great stuff Kingston could add in order to make it better, which I think is actually a very positive indicator of the direction that they're going with it. Stability first, and then trying to add more features. A lot of these wireless streamers just flat out don't work very well. The easy setup guide within the app is a little bit verbose. It's a little bit text heavy, not as visual as I'd like, but it covers all the basic stuff like connecting to the mobile light wireless through Wi-Fi, how to secure the connection, and then how to set up internet pass-throughs. So all three of these devices have internet connections, and they're streaming 1080p media from this thing at the same time. The app could definitely be prettier, particularly on the Android side, but the functionality is rock solid, and I didn't have to waste any time fighting with it to get it to work, so I think this is actually the first time that I've seen an app that really feels more mature and more solid on Android than it does on iOS. And kudos to Kingston for spending the time on the dominant platform, what is now the dominant platform, to make it actually work correctly. So often I see the iOS app is awesome, and the Android one is kind of like Frankensteined together, and even seeing both of them at parity is not as common as I'd like, but in this case I really felt the Android one was quite strong, even though the iOS one did look a little bit better. I mean, to be clear, guys, the iOS app is fine, it's functional, but it doesn't have the same number of features, and part of this is just iOS's fault in the first place. So for example, the ability to directly copy files back and forth wherever you need within the directory structure on the device is something that the Android app can do, but the iOS one can't. Something that I wouldn't mind seeing added to the iOS one is the ability to use a third-party player. So on the Android one I can use just the included player, I can use BS player, I can use whatever I want, so that I get great file compatibility, whereas on the iOS one it basically just isn't even detecting the media file types that it doesn't support. So that was a bit of an issue for me with the iOS one. I did test with up to three devices streaming 1080p, but these are reasonably low bitrate files, like they're not crazy uncompressed or anything like that, and there were no issues at a range that I'd consider to be reasonable, so anywhere within sort of 10 or 15 feet. Typically this is something I'd use for traveling in the car on a plane or something like that, so you wouldn't be tremendously far away from it. One cool thing is that it does allow both the USB port and the SD card slot to be used at the same time. So you can pack some serious storage punch if you want to. All you do is use the app to select which one you're interested in browsing, and you can browse the local storage on the device or built within the app on the iOS version as well. Kingston does have a one terabyte USB drive, and then you could throw up to a 256 gig SD card in there for a massive amount of storage. In fact, I've even seen people using them with USB hard drives. If you have a pigtailed connector, and then you use another USB connector for power and plug that into a portable battery bank or something like that. So there's a ton of flexibility here, and I think overall my takeaway from this review is that it's great to see how much these devices have matured since the early attempts like the expensive and unsuccessful Y drive. They still don't really make any sense at home since there are much better solutions like Air Video and Emit for streaming when you have, anytime you have a data connection like from your home PC across Wi-Fi or even on someone else's Wi-Fi, but for traveling, particularly on planes, these things are a godsend. The MobileLite definitely gets a green light from me at under 50 bucks, and I think it is a very, very smart buy. I guess I didn't really talk about it physically much, so it's got a USB charging port to charge the internal battery, a USB port for the USB drive, and then it has an SD card slot. I guess there's not really a whole lot to say. Power button, so you hold that to turn it on.
