although I binned the suggested app for 'Remote File Browser' (RFB) for iOS. I found the FTP server app a bit clunky and seemed over complicated. The RFB app has a nice front end and easily connects with other devices, just follow the on screen prompts.
Transferring files between my iPad 4 and the EasyAcc is as 50% of the name of the device. Connected media appear as files (RFB) and is as simple as copy & paste. This is an absolute bonus for me as I take a lot of photos (raw) and hate lumping around a laptop for backups. Now i use the iPad to transfer the images to and then backup, more often move, to a USB flash drive (or two, not forgetting its not backed up until its on Three devices) via the EasyAcc.
Haven't had the EasyAcc long enough to comment on the lasting properties of the battery pack but it has charged a few other devices with no problems. Noticed though it charged the iPad quicker than if charged from the mains!
Great price, good size, not heavy, very well packaged, works a treat, recommended.
Minor niggles, Connected CAT5 lead doesn't click lock. Wifi on/off slider switch too easy to turn on, I.e if moving around in your bag. Nothing a small piece of tape wouldn't sort.
