It's not every day that we come across a device which is simultaneously cheap ( by cheap I mean affordable), extremely functional and doesn't weigh a ton.
Let me introduce you to
I know that on the market there is wide offering of devices that possess similar functionalities. All major brands sell wireless hard drives that will sync with your iOS, Android and even Windows Phone devices. Personally I never did much photo editing on laptops, the only use I had for them was to empty memory cards or shooting tethered while outdoors. This nifty little device does all that and it still has a few tricks up its sleeve. Through a wireless connection you can transfer photos from your devices to an available SD card reader or to a USB storage media, be it a pen drive or a regular external HDD.
Having connectivity in mind the manufacturer included an ethernet port so that while connected to the device you can still access the Internet while uploading the files from your camera. It has a micro USB port for charging its battery or to connect it to the computer and use it as an SD card reader. Also, the internal battery that powers it can also be used to charge a tablet or smartphone (I charged my iPhone twice on a single charge of its battery). All this packed into a device that only weighs 171 g. It also can stream media to several devices since it's able to read a good variety of file formats. Although it can store any other formats.
At the end of this post I placed at PDF with its full specs.
Last but not least, it's price; I got it for around €40, a bargain.
