Everyday, for 5 days in a row, I would allow my phone to drain as much as possible as you can see below....then the next morning I would charge my phone using only the Anker Powerbank until it was fully charged.
Here are the results!
*Charge #1 = 15% to 100% power in 1 hour 35 mins. (4 solid lights)
*Charge #2 = 20% to 100% power in 1 hour 30 mins. (3 solid lights)
*Charge #3 = 08% to 100% power in 1 hour 45 mins. (2 solid lights)
*Charge #4 = 03% to 100% power in 1 hour 50 mins. (1 solid light)
*Charge #5 = 20% to 100% power in 1 hour 25 mins. (1 Blinking light)
The next morning (on day 6), I tried recharging the phone again while the 1 remaining light on the Anker Power bank was still blinking .....
It basically went from 14% to 21% power before the Power bank ended up running completely dry.
So all in all I was able to get "5 Full Charges" from this one Power Bank with my Samsung Galaxy S7.
Hope this helps anyone who is undecided on pulling the trigger!
Most of us would agree that we all carry or own multiple devices in this day and age and they all need frequent (1x /2x/3x times a day) recharging after continuous usage. I personally travel a lot for work and I find myself needing battery juice for my devices on a very frequent basis. I carry 2 cell phones and 1 tablet for work.
I obviously own couple of power banks to charge my phone during my flights or at the airports. I always thought it would be great if one these days they made a power bank which could charge all my devices few times and it wasn’t so heavy. Well, guess what Anker PowerCore 20100 is the answer.
First and foremost, the capacity of this device is amazing and recharging of your devices is superfast. The unit itself comes pre-charged to about 75%came charged, so you can start using it out of the box.
My test: After recharging it to full 100%, I took it with me on my business trip. I was able to charge my Samsung S6 and iPhone 6 at the same time (from 30% to FULL 100% in less than 2 hours). The Power Bank still had more than 50% juice left. I quickly plugged in my Samsung Tab S and charged it from 70% to Full 100% in less than 40 mins. I was surprised to see that the unit still had more than 50% juice left. Long story short, it took me full 2 days and almost 7-8 device recharges to drain it down to less than 25%. This unit has massive battery capacity. Since then I have ran multiple tests on this unit and it has NOT failed once to impress me.
As far as size of the unit, I own old version of the Anker powerbanks and few other units from other manufacturers. This one is a great improvement. This is probably good 25% lighter than older Anker models and it’s not as shiny as older models. I like the looks of this one better. Anker smartly got rid of the flash light feature which was nothing but a small LED. I personally never used that feature in my older model.
The four status LEDs are great and pretty accurate to show the status of battery charge left. Two USB ports allow charging, it’s rated at 2.4amp per port and total of 4.8amp. I think that’s pretty accurate during my testing. The unit comes with a single USB-to-micro cable and is charged via micro USB input on the side. It appears to be pretty well built unit that is both durable and attractive.
For recharging the unit itself, it can take somewhere from 8-10 hours. Best is to leave it plugged in overnight and you will have an enormous power capacity for the busy day or even the week ahead.
Anker customer service is the best I have seen, they are quick to respond and accommodating. The unit itself is backed by their 18 month warranty.
Overall, I'm extremely satisfied with the battery pack and highly recommend it. It's a great battery backup for those on the go or even at home if you don’t want long recharging cords from power outlet to your desk.
Bullet Point Analysis:
Families on vacation
Busy Moms & Dads on the go

Dimensions: 6.5 X 2.5 X 1
Output: 2 USB/ 4.8A total
Input: 5V / 2A
About 1” bigger than Samsung S6 and 1.5” bigger than iPhone6
Substantially lighter than any other power bank with same capacity in the market.
Capacity is as promised
You can use your existing cell phone charger to charge the device
I think it’s established that in today’s digital and multi device environment our devices are power-hungry at all times. I have seen people at Airports, Hotels, Coffee Shops, Office Receptions, Disney World, Museums (yes), Casinos etc plugged into power outlets. Phones and tablets are more advanced but they need battery juice and manufacturers have conveniently taken spare battery option out of the devices e.g. Samsung.
This Anker Power Bank makes perfect sense to carry for all your smart phone and tablet charging needs. You can't beat the battery capacity, size, weight, price for the use you will get out of it and to add its backed by a good company who listens to their customers. I would say go for it!
Please do let me know if this review was helpful to you. If it was not, let me know why in the comment section. I promise that my review is fair and honest.
I've reached out to Anker for assistance and received no help. I'll be sending this back.
EDIT 04/2016: Anker reached out to me in private over a month ago, shipped me a new PowerCore free of charge and I confirmed that it was properly putting out over 1A. In addition to this, they replaced an older model PowerCore that had stopped working and I assumed was out of warranty, so I had taken it apart to diagnose what was wrong with it (bad capacitor). Not only did they ship me a replacement, but they let me keep the broken PowerCore so I could harvest the 18650 batteries from it.
This is quality customer support and they probably ate a little bit of profit in assisting me. Not only am I raising this review to five stars, I will continue to consistently buy from Anker.
