Anker PowerCore 26800 Portable Charger, 26800mAh External Battery with Dual Input Port and Double-Speed Recharging, 3 USB Ports for iPhone, iPad,…

After testing I’ve found this 26800 battery is slightly worse on all metrics compared its smaller 20100 sister. (Which is great) The two unique advantages of this battery are 1) large capacity, and 2) dual-input fast input charging. Both of these features have smallish benefits comparison to Anker’s other offerings.

1. Using a load testing device, I measured the Watt/hours that this battery can deliver. 75.599Wh @5v. (Rated capacity is 99.16 Wh) This means that the battery is 76% efficient. In contrast, the 20100 battery delivers deliver:61.211Wh @5v. (Rated capacity is 74.37 Wh) The smaller battery is 82% efficient – 6% better than this larger brother. This means that even though the 26800 looks like it will give you 33% more power, it only really gives you about 23% more juice than the 20100.

2. It doesn’t seem to deliver it’s maximum advertised input charge speed when using the special dual-input charge method. Using a single cable, the charge rate “bounces around” at different speeds for about 10 seconds before settling on a final sustained charge speed. Usually, this will settle at a speed of 2.0 amps (which is a decent speed for a single cable). When adding the second cable however, this 2.0A speed of the first cable is reduced, and the two cables together will never charge the battery at more than a total of 3.0 amps. (The previously fast 2.0A connection will be reduced to something like 1.2A when the second cable is connected, and together they equal roughly 3.0A) Moreover, if the second cable is unplugged the remaining cable will often drop down to a slower charge rate like 1.0A. The battery then needs both cables to be unplugged so that it can “reset” and give another try at charging quickly.

Summary: After the most recent $15 price cut (currently) $65.99, the price of this battery is 46% more than the 20100 for only a 23% increase in usable capacity. If you need alot of battery capacity, the better option is to buy two 20100 batteries. You’ll get much more capacity for the money, and you’ll be able to charge at an effective 4.0A because the batteries are independent.

I tried to like it, I really did. Unfortunately, the power bank failed to live up to expectations and is getting a return label shortly. While it does seem to have large capacity, it doesn’t live up to the charge rate claims. No device and cable combination I could come up with resulted in more than roughly 1A for a charge rate. This included OEM cables and devices that are fitted with fast charge and quick charge capabilities. I tried them with and without the meter inline to make sure the meter wasn’t impacting things, but the remaining charge time was the same in each instance.

I bought this powerbank because I trust the brand as I own just one bluetooth wireless headphones from Anker adn have never experienced any issues. When the opportunity came to buy a powerbank in the black Friday sale, I chose to buy this fast charging one…and omg…I was blown away! It’s worth every penny. Those days are gone where you patiently check your phone every 5 mins and only see that it goes up by 1% . This is worth its weight in gold. I use it regularly and feel safe leaving home knowing that my phone/kindle/bluetooth headphones will all be ok.This powerbank has come with me to 4 destinations, although heavy in weight its truly worth it. It was oddly satisfying to know my partners cheaper powerbank couldn’t keep up- As they say, buy cheap pay twice. You can leave it uncharged for up to two weeks with regular use, which is good because you never have to remember to charge it, but bad if you’re thinking you’re carrying additional weight for nothing. I wish was there was an in between! Other powerbanks tended to charge my bluetooth wireless headphones initially then after leaving it in your bag the other powerbank goes into standby and stops charge, with all 3 different powerbanks- No problems with Anker! Buy and trust Anker always! Don’t waste your time and energy with all the cheaper versions no matter how enticing the price drop is, you’ll be the one who is left with a sub standard product long after the excitement of the price drop wears off. You’ll be the one asking for replacements 6 months down the line. They just don’t last as long! if its not the cable, it’s the bank..I would know, I had 3.

Great Product, Fantastic Quality.
I originally bought this as a Christmas Gift for my mom, but liked it so much I ended up buying another one for myself.
Thus is such a great portable charger, I can charge my phone like 10+ times with it, and it still has battery life remaining, and I can charge my tablet 3 times on one charge.
Great Power output, charges devices very fast.

This device has two charge ports, which is very convenient as you can charge it twice as fast, and both cables are included!
Would recommend to anyone looking for a reliable power bank that will never break or give out on them!

I love the product! The performance is great as it lasts long with several charges on my phone, charging time is a breeze with the double charge feature and the look of the battery pack itself I find astonishing. Although it is a product with great performance, I did not like the shell of the battery pack. Very easy to get the outer layer damaged with scratches. A slight rub with metal on the surface of the battery will leave a permanent scratch mark, which bothers me as it ruins the look.

Edit: I purchased my second product (same one) and have the middle port defective. I called to see if I could have a new one shipped to me (like the first one), but they told me that I would have to return it to the company to have it inspected. That is no problem to me until they said: “…you would have to pay for the label”. I am not happy with the customer service at all and that the both products I have gotten from the company have/are defective. Complete disappointment.

Die Powerbank verfügt über zwei Micro-USB Eingänge über die eigentlich mit 2x 2A geladen werden kann. Das funktioniert jedoch nur, wenn dafür zwei USB-Ladegeräte verwendet werden.

Benutzt man ein Ladegerät, reduziert sich der Strom auf 1,4A bis 1,6A pro Port. Damit wird dann nur noch mit ca. 3A statt mit 4A geladen. Ich habe 5 verschiedene Ladegeräte getestet und bei allen reduzierte sich der Strom von 2A auf ca. 1,5A pro Port. Die Ladegeräte hatten dabei selbstverständlich ausreichend Leistung und zwei waren von Anker.
Ich habe sicherheitshalber auch eine zweite Powerbank bestellt und getestet: Leider mit exakt gleichem Ergebnis. Also jedes Mal reproduzierbar.

Wird die Powerbank an zwei Ladegeräte angeschlossen, wird sie mit 2x2A geladen. Sobald man aber beide USB-Kabel in ein Ladegerät steckt, reduziert sich die Ladeleistung wie beschrieben.

Der Support war freundlich und bemüht. Man schickte mir auch ein Foto auf dem eine Powerbank mit Messgerät zu sehen war welches 2A zeigte. Keine Ahnung wie das funktioniert hat.
Bei meinen 2 Powerbanks und den 5 Ladegeräten klappt das aber definitiv nicht.
