Everybody needs an external battery nowadays, but there are so many to choose from on Amazon. Anker is one of the best selling brands for external batteries, cables, and miscellaneous electronic gizmos, and this product is yet another one of their well thought out creations. I've tried Aukey and RavPower, but they do not come close to the user support (easy support emails / constant interaction with disgruntled reviewers on Amazon) that Anker has to offer. If anything goes wrong within the first 18 months, rest assure Anker will make things right.
This battery is a 6700 mAh battery that outputs 10 watts (5 volts & 2 amps) and takes in 5 watts (5 volts & 1 amp). I have included pictures of my observations with the charging of the battery (1 amp), the charging of my iPhone (~1.59 amps at 73%), and the charging of my iPad (~2.33 amps at 63%). This battery pack goes above and beyond the specifications and expectations. This should be capable of charging my iPhone 7 plus's 2900 mAh battery almost twice! (while the battery does have 6700 mAh, it's not 100% efficient. This is the case with all external chargers. Multiply it by a factor of 0.7 to get a more pragmatic usable mAh).
This battery pack is a glossy black finish (think the jet black iPhone 7) with a curved rectangular shape. One gripe is that there will be scratches that will inevitably accumulate on this battery pack. It comes with a mesh carrying case and a micro-usb charging / data cable. It has only one port, so you cannot charge two devices at the same time. However, that's what makes this battery worth considering. How often are you going to be out and about and use up all 20,000+ mAh of some gigantic battery packs out there? It's a lot of weight to be carrying if you're in a situation where you can charge up your battery every night.
I highly recommend this item and urge you to consider your needs before you purchase something significantly bigger, bulkier, and expensive than this.
After posting this review, someone from Anker reached out to me and offered to send a replacement battery. I have been using it for a week and it seems to be working decently. Because of that, I have updated my review to 4 stars because of the excellent customer service. Will keep everyone posted on how the replacement works out!
Once I got it I hooked it up to the wall charger and let it fully charge to the 4 blue dots which took about 4-4.5 hrs as stated. Then since my iPhone was at 19% I decided to try it out so I connected it with my syncwire cable and let it fully charge to 100%, which only took about 1hr 45min. Now thats faster than when I charge my phone without the anker!
Even after charging my phone the anker still has 3 blue dots left, so getting almost 2 full charges from it for your phone is possible like the company states.
Overall for $20 I'm extremely happy with my purchase and highly recommend this product to anyone who needs a extra battery for their devices for whatever reason. I'll also update this review after I have had it for awhile.
Edit: after taking the advice of their customer service I plugged it into a different ac adapter. The only one it seems to work with is the apple ac adapter which bothers me but the product works fine.

I've never actually used a power bank before, so this was my first one. I wanted to get a power bank to use with my older phone where my phone's battery doesn't last as long as it used to.
The physical size of this power bank is quite small, so it's easy to store and take with you on the go. It's small enough to fit in my pocket. The weight of the power bank is a bit heavy for the size, but I guess that's normal for power banks in general. While this is the first power bank I've ever personally bought and used, I've seen people use many other power banks, and they tend to be very clunky. This one offers pretty good capacity but it's very compact.
Before buying this power bank, I saw that charging it from the wall is only at 1A (input), but it can output 2A. So I was a bit worried about the slower charging rate to actually charge up the power bank itself. In actual practice, the 1A wall charging wasn't an issue for me. It doesn't take that long to charge the power bank to its full charge. I don't intend to use this power bank daily, but more as a backup for my old phone's weaker battery, so the 1A wall charging has been totally fine in practice.
As for the 2A output charging, this power bank does indeed charge my phone quite fast! This power bank is very convenient when traveling.
I also want to specifically mention the pouch that this power bank comes with. The pouch for storing the power bank is a mesh pouch. The pouch can actually stretch quite a bit, and it has a draw string at the opening to keep the pouch closed. Because this mesh pouch can actually stretch quite a bit, it's actually possible to store the power bank + small microUSB cable (that it came with) + my phone's 3ft USB charging cable, all in this one pouch. I was surprised how they could all fit in the pouch, but they do, and it's really useful and convenient to store them all in this one pouch while traveling.
This is a great product, and Anker's extra touches, especially including such a useful pouch with this power bank, is very thoughtful!
I like the size of the charger and appreciate the little protective bag that comes with it. It's a bit heavy but I can't really expect a battery this big to be super light. The plastic housing seems ok but I'm sure if I drop it in the future, the plastic will crack or break. However, I'm happy with this purchase
So far so good. The charge lights on the device are very helpful as well, thanks. Nice design.
I was really impressed when I charged my phone how quickly it actually charged. It is definitely worth the money just don’t be alarmed if your charging cord doesn’t work.
Edit 2019: Still works great. Charges my
iPhone 8+ very very quickly.
2. Excellent solid feel and build quality of the plastic
3. Small size and light weight makes it really convenient to carry around when traveling. I don't even notice it is in my pockets at times!
The price is a little higher than other power banks of the same capacity, but the quality of the product makes up for it.
I did have an issue with the charger after a couple of months where it basically stopped working, but the customer service was very helpful and kind, and sent a replacement after the actions they suggested didn't fix the issue. It was super easy to deal with them and honestly make you feel appreciated as a customer. I have a couple other Anker products and they all work pretty great.
