Bought this to power a raspberry pi 3. Bit disappointed since it was rated at > 2 amps and the device does not boot. Pi works with a regular charger.

Not bad

I have been purchasing Anker products with great deal of satisfaction. This battery pack does not seem to last as long as description depicted. I have battery pack that is one step below this and I am happy with that.

I'm only giving this 3 stars because the product does not come with everything you need to charge it up. This to me is inconceivable. You get 2 usb cables but no plug to actually plug it in to charge. So, if you are going to buy this product, make sure you factor in the cost of the plug for charging if you don't have any at your house already. That alone pushes the price up even more.

not bad

I have gotten in the habit of not giving any company a 5 star rating, so for now until this thing can hold a charge and is more reliable than it's competition we will see. So far so good, I've had similar chargers from RavPower that broke in less then a month so I am hopeful that Anker proves to be a better investment for my money and provides a far superior product. I will change this review in a few months to further show how I feel after using it more

throw the idea of portability out the window, and you'll like this power bank. It charges most things really quickly and the capacity is insane, but this thing is so tall and fat it sticks out of the pockets of all my pants. Sure, I can have it stick out of my back pocket but then i'd look mental. Which I do. Unless you're putting this thing in a backpack or bag there's no real way to carry it on yourself. Half the stars since it only does half of what I wanted it to do.

It doesn't support fast charging on the note 8

What I love about this battery pack is the amount of phone charges I get out of it. What I don’t like is the amount of time it takes to recharge the battery. I have spent several hours trying to get a charge on this only to get half way. I have yet to time it, I just know it isn’t quick even if your using two charging cables. I have used it for keeping my phone changed while spending the travel traveling through Japan, when I got back to my hotel room I had one light indicator left on my charge. To prepare for the next day I started to recharge it. By the time I was ready to leave my room the next day my charger had 3 light indicators illuminated. So after a full night to charge it didn’t even fill up my charge.

The media could not be loaded. After months of amazing use the product just gave out on me. It would last for days and now I can't even get it to consistently charge my phone, whenever I plug in my cord the lights flicker( Shown in video blow). I can't get it to charge my phone and I really liked this battery too. I apologize for the quality of the video the camera on my phone is currently all sorts of screwed up.
