Another great product from anker..This model doesnt support QC3. But i guess it doesnt matter if you use it to charge iphone or ipads..Some people complaining about slow charging, if you use 12 watt charger which comes with i pad, this battery charge faster..Before you own a larger capacity power bank, it is a good idea to invest in a quality charger..i am using a desktop charger from RAV power to charge my 3 large size power bank and all three of them ( all of them are 20100 mah power banks )can be charged fully within 5-6 hours . I am very happy with this product from Anker

They do not support QC3.0

Reviewed in Australia on 26 June 2020

Colour Name: BlackVerified Purchase

I have owned ANKER 10000mAh in the fast which was a miniature performance monster (as it fast charged my Galaxy Note 8). Unfortunately, I lost it somewhere and ordered this one to take its place. However, this didn't live up to the standards that were set by the previous one I owned. I realize that the ANKER Powercore do not support QC3.0 but I am sure they have their equivalent of "fast charging". Everytime I connected this to my phone (using 4 different cables), it showed cable charging. Therefore, I ended up returning it for a full refund. The search for a good power bank continues!

Excellent battery

Reviewed in Australia on 23 May 2019

Colour Name: BlackVerified Purchase

This is my first charger, and this is the best charger I have ever had. Which sounds stupid except for it holds 10 charges and hold them for so so long.

It is slightly larger and slightly heavy, so if you have a purse, and if it’s not a big purse, then probably get the smaller one. However should you require power for a speaker and a phone to play music all night on a camping trip this is the gadget for you

My favourite power bank so far 👍🏼

Reviewed in Australia on 8 November 2018

Colour Name: BlackVerified Purchase

May be a little heavier to keep the power bank in your pocket but it’s really worth it. I charger my iPhone 8 Plus 3 times & each time my phone battery was almost less than 5%. But still have 50% battery left in the power bank. After it charge it self 100%, it switch off automatically. Love this power bank unit. I still have a Cygnet power bank but so far Anker is my favourite now 👍🏼

Power to spare!

Colour Name: BlackVerified Purchase

Used this on a recent trip to Japan where both are phones were being hammered constantly using Maps and Translate. Charging two phones at once and quick charge output was a life saver! Convenient size and shape means it can slip into the side pocket of a backpack or overcoat pocket no problem. The protective fabric sleeve with draw-string closer is great for storing the charging cables in and keeping the cable in place when it is plugged in. Could not fault it!

Don't get any other Power Bank.

This is the best power bank on the market. Don't believe me, just look at other reviews. Works exactly as advertised, never have I drained the entire battery (even when traveling long distances). Always stay charged. It was a little heavy than I expected but it charges really fast.

Stops charging when device enters sleeping mode

Reviewed in Australia on 8 March 2020

Colour Name: BlackVerified Purchase

In principle it's a great device, looks of capacity, dual port.
However, not only is it heavy (which is to be expected given capacity), but the main issue is that the software is buggy and stops charging a device when it enters sleeping mode. Now in the recycling bin, using a Comsol that's more compact and works properly, plus it has a percentage charge left instead of 4 leds and a USB-C port.

Colour Name: BlackVerified Purchase

I'm amazed by the capacity of this charger. It has already saved me several times from running out of power on an overseas trip. It charges my iphone very quickly and it's easily and quickly recharged, too.
Only downside might be the weight, but I got used to carrying the charger around pretty quickly.

Great service & Better product

Reviewed in Canada on 20 April 2017

Colour Name: BlackVerified Purchase

After 5 months. It doesn't even charge my phone anymore it just keeps it at its current battery life. stopped charging my girlfriends iphone completely. and doesn't work on other micro SD products such as my portable speaker anymore.
*** UPDATE ***
Anker did send me a replacement free of charge been using it for a week and have had no issues and works even better than the first one I had right out of the box. If I do not update this again then the product has lasted and does the job great. If this one also goes bad after a couple of months I will update. ~ week 2

Powerful Portable Charger

Reviewed in Canada on 7 June 2018

Colour Name: BlackVerified Purchase

At the time of buying this I wanted to get a power bank as my current phone had a battery discharge problem and I was thinking I could extend its life by having a portable charger. I was looking around on amazon and found this. It had quite a few reviews and I have purchased anker products in the past and am usually pretty happy with it. I went ahead and decided to buy this.

It arrived quickly and the product box looked really nice. I opened it up and noticed that the portable charger was a bit bigger than what I anticipated. Inside the box was the portable charger, a usb cable, a carrying case for the portable charger, the warranty info and the manual. I immediately noticed the high quality of the charger. It feels solid in your hands and a bit heavier than I was expecting as well. There are some portable chargers that have extra stuff like a flashlight but this charger just sticks to the basic. There are two USB Ports where you can plug in your usb cable and then connect that to your device. Also, there is one micro usb port for charging the portable charger itself. Lastly, there are 4 LEDs on one side of the charger. These 4 LEDs represent how much juice is left in the portable charger. 4 LEDs means its at 100%. 3 LEDs mean 75% and so on. There is a button on the side of the charger as well. This button lights up the LEDs for you to know how much capacity is left. Anker uses their own technology to speed up the charging which is awesome. I did notice the devices I plugged in took The fact that you can charge two devices at the same time is pretty convenient as well. I have done this a few times and it works quite well.

There are a few reasons I took a star off. One of them is that charging the actual portable charger to its full capacity takes around 8 hours which is quite long. I understand the capacity is quite big but a power adapter for the charger itself could have been included. The other two reasons are weight and size. The weight and size are a little bit annoying to me as when I think of portable chargers I think of something you can put in your pocket and charge your phone at the same time. With the weight and size of this it is a bit difficult to do something specific like that. This is not a huge issue but it is just something I thought could be worth mentioning. I am aware now that anker and other companies offer smaller sized power banks. Overall, I am pretty happy with this purchase. I bought this last year and still can't notice any decrease in quality.

so I was happy with the product

Reviewed in Canada on 6 February 2018

Colour Name: BlackVerified Purchase

2 stars for the product, 5 stars for the customer service.

My first Anker 20100 Portable Charger died after 1 year - granted, I use it extremely often as I am a Pokemon Go player, so I was happy with the product. At that time, I did not realize there was a warranty, so I purchased a second one (same model, different colour) as a replacement. This Anker 20100 only lasted a few months before it died. Both chargers had the same symptoms: The charger is charged (2-4 lights on), when I plug it in it charges the phone for only a few seconds and then the charger turns off. I contacted Anker support and they were amazing, with few questions asked they sent two replacements within days. I was happily an Anker customer and ready to give a 5 star review because they stand by their products and I was hoping all would be well with the replacements. On day 1, one of the replacements had the exact same issue so it is unusable. I reached out this morning to see if there is a different product I can get instead because 3 portable chargers with the same problem is definitely a pattern of a larger issue. Overall: I would suggest purchasing an Anker product because of their great customer service, but I would not recommend this particular portable charger because I had 3 stop working within a year and a half.

Don't expect much after a couple of months...

Reviewed in the United States on 5 November 2016

Colour Name: BlackVerified Purchase

Pretty disappointed. It hasn't even been 6 months, and one of the ports don't charge anymore. TBH, after doing some review reading, I was excited about this charger. I bought one for myself and one for my friend. I'm not sure how his is doing or how often he uses it (I don't think that should matter regarding the ports, I can understand if the battery dies over time....hopefully not a short amount of time). I usually use it over the weekends, and took it on another weekend trip to find my self short a charging port. Definitely annoyed!

EDIT 11/08/16: I was contacted by their customer service team the following day after writing this review. Their team was very pleasant to deal with and quick with their responses. Within a day or two, they've already sent out a replacement for the faulty PowerCore 20100 I purchased a couple of months ago! If all goes well, I'll be updating this review again! Great customer service from Anker!

EDiT 2/16/17: Anker's customer service is second to none! The replacement works as it should, but the wire would not charge the PowerCore. After contacting their customer service team again, they were happy to replace the faulty wire sent with the replacement PowerCore. Great company that cares about their customers. I just wish products nowadays lasted longer, but regardless, I'll be buying their products again.

Excellent Anker Customer Service

Reviewed in Canada on 5 June 2018

Colour Name: BlackVerified Purchase

When I first received it, it wasn't half full and it did take a long time to charge. So I decided to upgrade to the 26800+ that came with the Qualcomm Quick Charge 3.0 and Powerport. Anker reached out to me and assisted me with the issue that I was having. This is still a great product. If you wish to buy this model, I also recommend that you buy the Anker Powerport...Will make life easier.
Thanks to Anker, their exceptionally excellent customer service, and their client appreciation...I am a very happy customer. Great products, excellent quality, and excellent service. I highly recommend any Anker product, as Anker does stand behind their products and quality.
