Regarding the battery I do not belive its a 12000mAH battery maybe 6 or 7000mAH is the right one, this one has USB port 9V-11V-12V-14V-19v and its posible to connect up to 3 diferent devices with a maximum of 70w.
The only problem its when you conect to the battery a radio like elecraft KX-1 than drain just a few mA in this case the battery switch off automatically after couple of minutes because can no detect de radio conected, this is no problem if you plug the FT-817 at 12v output.
The Alexloop its a bit overpriced antenna but really do the job, its well done and come with a portable bag, very easy to adjust, just lisen for the band noise and finish looking for lower swr at the radio, all this take a few seconds.
40m its a dificult band not for swr but its dificult to do some QSOs there, its just a small 1m loop and the 40m its a plus band than allow to do some QSO but with poor results. All other band 30 to 10m are really a pleasure to do a QSOs with such a small antenna.
