I am not a light user. I don't understand how people with Iphones even function. My screen brightness is always up, consuming media-youtube, torrents (video), documents from work, Team Viewer controlling my desktop from mobile (lol), bluetooth & headphones-spotify, GPS-maps for transit times, and LTE. I read entire Kindle books on full brightness, I administrate online groups and am in constant contact with people, ect.
So, I went with this (It has a 3 amp output), and surprisingly it charges my device noticeably faster than my after market 2.5 amp charger at home. You will notice it. This is perfect because I am always busy, and only get 30 or so minutes at the most between my commitments where I have the time to plug it in. It would be good for someone taking city transit too. This is sufficient time to restore a huge portion of the battery, even for larger devices with an already large capacity like mine. Looking back this was the superior choice considering my usage and my device's battery design.
There is a lot more to say but I think the other reviews on here have already touched on it all.
Device itself - great potential. Worked well for about 2 weeks. Compare to aukey 12000 mA I got recently, it charges faster and it takes less time to charge itself. For both chargers I am using ipad air charger.
However, starting past sunday, I noticed that one of the ports charging well, my ipad air gets full charge in about 4 to 5 hours. As for second port, I leave my ipad air overnight and, the charge is about 60% and stops right there. It is difficult to verify as it takes long time to test. I have to fully discharge my ipad and charge it again, then switch ports... I tried three times so far and, that seems to be the case that one of the ports does not function properly.
I purchased one more charger like that to give it as a gift but, may just send them both back.
Received replacement for defective charger. Service from Anker is excellent. Charger works as expected.
I haven't had any issues in the two years I've been using it.

Solid build and a whole lot of storage. A bit of a fingerprint magnet.Published 6 days ago by G West

A well made product. Works as advertised. I found the charging cord that comes with the power pack a bit short. Just my personal opinion.Published 11 days ago by Amazon Customer
