I have two of these J5 Create Quick chargers and they work really well. I’ve been testing them for a few months now. I have one at home and another for travel. They are dual voltage (100-240VAC) so they will work world wide (tested in Italy just this past week).
If you buy three or more mobile items you will get a good discount on them at best buy. (I got this charger and 3 lighting cables) I can charge all 8 of my goTenna’s at the same time (with a USB spliter) or any combination of Iphones, Ipads, battery packs, gotennas, etc
