Charging the Charger

Reviewed in the United States on November 20, 2019

Color: BlackVerified Purchase

Six hours on a wall charge since it was delivered, and the charger is only at a blinking 4. Have always loved Anker, but if it takes this long to charge the charger, it's not the one for me.
*** this is an addendum to the above review. After working with the charger for some time, I now realize that the sheer volume requires long charging times. I absolutely love the thing, and would give it five stars!

Excellent product 5 star service from the seller

Reviewed in the United States on November 15, 2019

Color: BlackVerified Purchase

I purchased this product to charge my phone and any other items while out on a hiking trip. I was out 4 days and used my phone for pictures and video running the battery to less than 30% each day. I was able to charge my phone during the whole trip and still had 4 lights showing as a full power on the charger. I continued to use the charger when I got home just to see how long it would last. It was at least 4 more days before I was down to a point where I recharged the charger. The recharge on the charger took about 16hours or so. The product Anker is amazing and I highly recommend. As far as the Amazon Seller, hats off, prior to my hike I lost the mesh bag that comes with the Anker. I liked the mesh bag because it gives some cushion to the charger while it is in my pack. I contacted the seller and they sent me a new mesh bag no charge. Above and beyond what I expected. I will probably buy another charger from this seller as a gift.

Anker nails it again - Great power bank

Reviewed in the United States on November 6, 2019

Color: BlackVerified Purchase

I've used Anker products for a long time now, everything from their cables, hubs, chargers and battery packs. I needed a new battery pack to take with me on long road trips and the occasional hiking and camping trip and this Power Bank has been great so far. It's even smaller than my Anker PowerCore+ 20100 bank!

Perfect

Reviewed in the United States on October 22, 2019

Color: BlackVerified Purchase

This is honestly the the nicest power bank I’ve ever owned. It’s design is stunning, the tiny texture provides a nice feeling holding it, and it’s one of the quicker 20000 mAh chargers (receiving and delivering power). I love that it accepts usb-c charging and that it has two out ports. I bought it because I love attending music festivals and needed the extra battery life, which this is perfect for!

Absolutely awesome powerbank. Totally a must have for all the tech junkies. Charges super quick. The greatest part is that it can charge two things at once. Better than that is that it knows which will need to be charged faster.

Another quality product from Anker, best deal I've found

Reviewed in the United States on November 22, 2019

Color: BlackVerified Purchase

I got this on sale for $32 which is an incredible deal for 20,000 mAh, I question the mAh ratings of some of the cheaper weird brands on Amazon, but I've bought a lot of Anker products and they have always been honest with their specs and held up over time. As far as legit brands go this is the best price you can get. It looks nice and comes with a case. I appreciate the USB C input. This can easily charge up 2 phones at once, pretty quickly and still have over 50% left. No adaptive fast charge or USB-PD, but at this price I don't really expect that. The 2A charging it plenty fast enough to charge my galaxy S10 while it's being heavily used.

Great product. I would buy another.

Reviewed in the United States on December 9, 2019

Color: BlackVerified Purchase

First of all, I love every Anker product I have purchased! I have not had one negative experience with any of their products. I have purchased Bluetooth speakers, multiple home and car chargers, and had purchased one of their portable batteries that I was very happy with. I seemed to have lost that battery, so went looking for another. This was the biggest portable battery that they offered. I jumped on it. Great price and a large capacity. I use this during hunting season, as we have no power sources for charging devices such as phones, ipads, night vision scopes, etc. The current product was charged up (takes a while) and transported to the camp. I used it to maintain my iPhone battery three times from 10% to 100% , then my son used it about the same amount and after three weeks, it is still showing full power indication. This is hands down a great purchase. I would buy another and any product that Anker makes, I trust fully to perform better than they report. Thanks, Anker for such a great product.

Mogelpackung / Falschangabe der Kapazität

Reviewed in Germany on May 10, 2020

Color: BlackVerified Purchase

Ich hatte vorher No-Name-Akkupacks gekauft, die aufgrund der gemessenen Kapazität zurückgingen. Als Maßstab dienten jeweils Handys mit deren Akkukapazität. Theorie: Wenn also ein jeweils leeres Handy mit 3600mAh ich 6x aufladen kann, und das Akkupack 20000mAh liefern soll, würde das irgendwie hin kommen -- Wandlungsverluste, Alter des Handy-Akkus, Erwärmen der Akkus mal außen vor gelassen.

Bei den No-Name-Produkten bin ich immer bei gut der Hälfte der Kapazität gelandet und habe die dann entnervt zurück gesendet.

Gut, dachte ich mir. Dann kaufst du halt ein Markenprodukt, mit der Marke hast du ja vorher zumindest gute Erfahrungen gemacht.

Leider war Anker auch nur minimal besser. Ich habe dann den Support von Anker geschildert, dass ich so 12000mAh bis wohlwollend maximal 14000mAh Stunden herausbekomme, was die als richtige Messung bescheinigten.

Nach Inspektion der Rückseite (Bild) war mir als alter RC-Car-Fahrer klar, dass die 20000mAh bei 3.6V (LiPo-Akku) anliegen. Daher steht auf der Rückseite auch 72Wh. Nur das wird halt durch einen Step-Up-Wandler auf 5V gewandelt. D.h. aber, dass das Akkupack nur erwa 14400mAh hat = 72000Wh / 5V.

Die Angabe von 72Wh ist also richtig auf der Rückseite, leider nur bei den internen 3.6V kommen da 20000mAh raus. An der 5V USB-Buchse halt nicht. Nur das zählt halt für mich.

Ich hatte den Support dann auch mit dieser Rechnung konfrontiert, was die mir bestätigten.

Der Support bot mir dann 15% Nachlass an.

Für mich blieb das halt trotzdem ein nach meinem Dafürhalten illegale Kennzeichnung, die rechtlich zu klären wäre.

Rückblickend glaube ich, dass die No-Name-Produkte das genauso gemacht haben. Da habe ich mir das ja nicht so genau angeschaut. Vielleicht gibt es sogar gar kein Akkupack, was richtig deklariert ist und das ist Usus so.

Richtig und ehrlich dem Verbraucher gegenüber ist das keinesfalls.

Sollte das jemand mal durch eine Verbraucherzentrale oder einen Anwalt klären lassen, wäre ich für einen Kommentar dankbar.

ANKER PowerCore Essential 20000mAh VS. POWERADD Pilot X7 20000mAh

Reviewed in Germany on December 29, 2019

Color: BlackVerified Purchase

POWERADD Pilot X7 20000mAh VS. ANKER PowerCore Essential 20000mAh
Beide Produkte wurden unter den gleichen Voraussetzungen getestet: ca. 20°C Raumtemperatur, ca. 50% Ladezustand und den selben Ladegeräten, Kabel und Verbraucher.

Pilot X7:
Gesamtkapazität Input: ~18400mAh
Gesamtkapazität Output: ~14100mAh
eff.: ~76,63%
max. gemessener Strom beim Auflagen der Powerbank: 1,28A
max. gemessener Strom beim laden eines Verbrauchers (USB-C Kabel) USB1: 1,6A
max. gemessener Strom beim laden eines Verbrauchers (USB-C Kabel) USB2: 1,6A

PowerCore Essential:
Gesamtkapazität Input: ~19900mAh
Gesamtkapazität Output: ~15200mAh
eff.: ~76,38%
max. gemessener Strom beim Auflagen der Powerbank (Micro USB Kabel): 1,02A
max. gemessener Strom beim Auflagen der Powerbank (USB-C Kabel): 1,8A
max. gemessener Strom beim laden eines Verbrauchers (USB-C Kabel) USB1: 1,6A
max. gemessener Strom beim laden eines Verbrauchers (USB-C Kabel) USB2: 1,8A

ACHTUNG: alle gemessenen Daten können beim Gebrauch von anderen Verbrauchen bzw. Kabel und ohne zwischengeschalteten Messgeräten stark Schwanken. Auch die Kapazität der Akku`s kann nach mehreren Zyklen oder Temperaturunterschieden Stark nachlassen dies trifft jedoch auf Jeden Akku zu.

Fazit: Sowohl ANKER als auch POWERADD sind sehr gute Hersteller, die Effizienz der eingebauten Elektronik wird sich in den kommenden Monaten hoffentlich steigern. 2018 habe ich das Model: Pilot 5GS getestet und habe eine effizient von ~78,11% erhalten.

I hope it's as good as my last one

Reviewed in the United Kingdom on December 10, 2019

Color: BlackVerified Purchase

I've had a powercore 20100 for a while now and I can't fault it, however, it's a little tired and having upgraded I'd prefer a powerbank that charges with a usb-c conection so I bought this. It's been on charge for around four hours and it's only got two charge lights illuminated so I'm hoping that is a glitch because at this rate it will take 24 hours to charge. Also I'm not sure I like the new design (totally personal preference) as the older version seemed more robust. I hope tomorrow it's charged as I can not fault Anker for their products. Finally I'm a little surprised it doesn't feature fast charge as most phones now have that capability (that is a lesson in reading the description). I will update once it is charged.

The charge took around 16 hours which is around 6 hours longer than my old powercore. I will.drain them both and do a back to back comparison.

Ich habe mir das hier gekauft damit ich ein großen powerbank habe für alle Fälle da ich mit anker Produkte sehr zufrieden bis herr war wurde ich hierbei etwas enttäuscht.
1.Zum ersten da es leider nur eine usb Kabel dabei ist und kein USB C weil mit dem Normalen anschluss muss ich immer vorsichtig sein habe angst das es abbricht mann hätte einfach ein usb c Kabel mitliefern können.
2. am Anfang konnte ich meinen iphone X mehrmals aufladen und jetzt komme ich bis zu drei Aufladungen habe noch einen vom anker der 10000 hat der funktioniert besser wie der hier werde mir das noch mal paar tage angucken ansonsten geht es wider zurück.....

Nachtrag
Kundendienst hat sich bei mir gemeldet und mir ein Ersatz zugesendet bester Kundendienst die mann sich wünschen kann alles bestens gelaufen bin sehr zufrieden deshalb kaufe ich auch nur vom Anker da kann mann nichts falsch machen danke Anker Team weiter so.
