    little flaws right out of the box, but seems like a good product
    5 Stars
    little flaws right out of the box, but seems like a good product
    I will be updating this review over time.6/7/17-I received the package today after some trouble receiving it. That was a problem on Amazon’s end not Anker’s. The packaging is always amazing for Anker’s products. It fits perfectly is sleek and organized. It comes with a short micro usb charging cable that looks like it will hold up for a while. And the battery itself came with a half charge.Unfortunately the first thing I noticed after taking the battery out of its protective sleeve was a very faint scuff along the curved edge near the middle of the battery. Not a big deal figured maybe it was bumped or scraped before packaging. It’s also not a big deal to me because most people probably wouldn’t notice it but I tend to be hypersensitive to these types of things (Not including photo as it is hard to see). Second thing I noticed was the little protective bag that came with it. It looks interesting and is obviously made to protect the device as it is slightly padded. But, I noticed right away that a strand was hanging on top near the opening. It’s a cheap bag I was not expecting to receive anyway so I am not too upset about that.But there are many things I like as well. I plugged my phone in and my old iPod in at same time and the led lights still indicate the battery charge at 50%. I am pleased by the fact that it seems to hold its charge very well. It’s a sleek design. It’s nothing special, but looks modern. Seems durable, but we’ll find out over time. Came with a bag I was surprised to receive that is a nice addition.Only reason I’m currently giving it 4 stars instead of 5 is because of the two little flaws that stood out immediately. If there was a 4.5 star option that’s where I would put it. If it works up to my expectations over the next couple weeks I will happily change it to 5 stars.6/25/17-It has worked up to my expectations if not exceeded them. It holds enough charge for long trips. Seems to charge my phone around 5 times. Which is plenty. But I’m not sure on that. I tend to use the phone while it’s charging so I’m sure that skews the estimate that is advertised.The one problem I did face though was that the block itself charges very slowly. It seems like it takes almost 24 hours to charge fully from a depleted state. I don’t believe it’s the port I’m using to charge with as it is an Anker IQ port. Also, I use the Anker cord that came with it usually. But, it holds a lot of mAH I understand why it takes so long. I wish they would have used usb c on the charging end to help with this problem. But, the micro-usb is convenient as I have those cords everywhere.12/30/17- I’m currently on vacation and have been for 3 days so far. I’ve charged my iPhone X about 3 times and my Bluetooth headphones after my plane ride with this brick. I’m very happy that even with fairly heavy use it performs great.Bottom line:Great product, great company, and I would definitely recommend getting this.

    5.0 out of 5 stars Excellent portable charger when Quickcharge and travelling ultra light are not important
    Reviewed in Canada on June 22, 2016
    As an avid nature photographer, I often find myself off the grid, with no or limited access to power sources for charging my phone, camera, and other portable electronic devices. A friend of mine recommended the Anker portable charging devices, so I decided to give them a try. Here I will review the PowerCore 20100.

    PACKAGING: I’m not usually one to care about how a product is packaged (as long it isn’t damaged in transit) - but I have to say, Anker has done a superb job packaging this thing. Maybe not quite at the Apple level, but not too far from it. As soon as you open the box, you get the impression this is a premium product.

    BUILD QUALITY: I’m extremely impressed with the build quality of this product, especially given its very reasonable (dare I say low) price. It feels very dense and solid, while not being unreasonably heavy. At 358 g + 10 g (pouch) + 14 g (cable), this may be getting a bit heavy for hiking/backpacking trips, but is quite lightweight for just about anything else (car/plane travel, car camping, etc.). Speaking of the pouch, this is probably the best soft carrying pouch I’ve ever seen included with an electronics product. It’s made of a nice lightweight mesh, which is lined internally with a thin foam padding that gives added protection against bumps and drops. The USB A ports seem to be of really nice quality, and have a great feel to them when you insert a USB plug into them. This model has two USB ports, allowing charging of 2 devices (at up to 2.4A each) simultaneously - this is a very nice feature to save time when multiple devices need to be charged. The device has a small 4-light LED indicator that provides information on the current charge level, which is very useful for knowing how much juice is left in the battery pack. While not charging or being charged, pressing a small button on the side of the device will activate the LED indicator. The only minor complaint I have is that plugging a cable into the micro USB port is a little more resistant and finicky than I’d like.

    CHARGING: When using this device to charge my Samsung Galaxy S7 Edge (3600 mAh battery), I get an average charging rate of about 1.3 minutes per % (so about 130 min. to fully charge the phone). This rate is similar to what I get from standard (non-fast charge) 2A wall chargers. The PowerCore has the capacity to fully charge the phone just under 4 times, which is expected given the 60-70% efficiency quoted by Anker on their website. In terms of how long it takes to recharge the PowerCore itself, it takes about 11.5 hours to go from empty to full (using a 2A USB charger). One nice feature to point out is that there is no on/off switch - when you plug in a device, it starts charging, and when you unplug it, it stops. So no need to worry about forgetting to turn the charger on or off.

    PROS:
    - Very well built, and seemingly durable
    - Reasonable weight, given the charge capacity
    - Good length micro USB cable and excellent quality carrying/storage pouch included
    - Charge level indicator
    - Charges devices at a good rate
    - Does not need to be switched on/off

    CONS:
    - Time to recharge the PowerCore 20100 is somewhat on the long side, making things a bit tricky. For example, if you wanted to charge overnight, you’d need to start it charging a couple of hours before going to bed, and leave it charging for a couple more hours after waking up - this is a bit awkward.

    CONCLUSION: Overall, I’m very impressed with this product. It appears to be a high quality product that offers a great set of features. No, it doesn’t have Quickcharge capability (either for charging or for being charged), but given its low price, it offers excellent value. Unless Quickcharge is important to you, I would highly recommend this battery pack to people looking for a super convenient way to charge their electronic devices while travelling.

    PICTURES: Among the attached pictures, I’ve included one of the PowerCore 20100 beside a credit card, and another of it beside the PowerCore 10000, to give a relative sense of size.
