Well it arrived early, yesterday afternoon.
After taking it out from the packaging I noticed (love the new shake to wake feature) it only had 4 bars of power, so like I do with all devices that have a battery I left it to charge.....
After 4 hours all lights went out indicating a full charge so to work it went..
Plugged one end into the 'Smart' connection and the other into my iPad 4 and immediately noticed the charge light came on.
Now this is a first as no other portable charger I have tried offered enough power to actually change the battery symbol indicate it was charging the Pad.
As to charging; this device is MAGIC. Not only did it indicate a charge but it did so at the same level as the mains charger that comes with the iPad 4.
At long last I now have a portable charger for the hungry iPad 4.
Am I happy? You bet I am. So much so I will now order another one to keep as a backup.
Please let the guys at Anker know and my sincere thanks to you in providing all the info.
.........I don't always get your questions right.... but you'll certainly know I've tried.
P.S. Many thanks for the Thanks votes. Thanks received are converted into a charitable donation.
