Anker PowerCore 5000

I recently ordered a PowerCore mini for my wife around dec 5 2016 and received it January 20, 2017, Damn that’s a long time to wait for a product that usually takes about two days to get in your mailbox. I think someone swiped the first one they sent. So I contacted Anker’s customer service to find out what was happening with my order and to make a long story short I just received power core mini yesterday. That’s why Anker and their customer support is top notch as is their products. And by the way, my wife loves the little power bank.
Highly recommended
