Legendary Anker product and service!
I’ve been a fan of Anker products for a while now and they’re my first choice brand. Excellent quality products and value for money and backed up with first class after service for peace of mind. Simple yet robust. It charges my devices quickly and is more than enough for me to use out and about for a number of days. I don’t stress out anymore with this by my side. It’s not the fastest in charging up but understand it’s better for product longetivity. Fine by me and just plug it in overnight and good to go by AM. What sets Anker apart is the after service if anything goes wrong. I’ve seen it reported by other people and I got to experience it recently. I had found the micro USB connection for power input always a tad loose from the beginning. I let it go as I could get by. Then it reached a point where it was difficult getting a secure connection. I sent Anker an email with a description of the problem. Initially I asked for just a new cable because a different cable did help make it better and I didn’t want to get into a bun fight. Anker asked me a few questions to ascertain root cause and concluded the port was faulty and sent me out a brand new powerbank very quickly! Wow! Am very impressed. A company that didn’t just do the bare minimum but wanted my compete satisfaction. You’ve certainly got that. Well done and thanks again Anker! Update: 7 June 2019 I bought the original back in July 2018. A replacement as per above was sent to me due to Micro USB port being faulty. Gave great service and the unfortunately the replacement developed a fault when whilst charging it would stop after a few minutes. Contact led Anker and again they responded quickly and sent me out a new one with no quibble and very quickly. They were naturally disappointed that I had to contact them again and I accept that it is rare occurrence. Very happy with the after service of this company and they’ve come through for me again.

and searching the internet for the best one to get was overwhelming
This is my first portable charger, and searching the internet for the best one to get was overwhelming, so many to choose from, and all claiming to be the best! I decided to stick with Anker as their products have always felt like a quality piece of kit, nicely built and the finish is always aesthetically pleasing (verging on sexy!). They come with an 18 month warranty and customer service that’s second to none. The packaging with Anker products is always impressive. It's like opening up some ultra-expensive pressie. Sturdy box, inserts, instructions complete with a little mesh bags and a short quality micro USB cable (you need to purchase a short lightning cable if you have apple products) What is it? It's an external battery that you can use as a portable power source to charge stuff with. It has IQ, which means you don’t have to work out if it’s the right power to not damage your pride and joy. You charge the Anker PowerCore 20100 up from a wall outlet (which I did overnight), and when charged, it contains about as much power as seven or eight modern smartphone batteries. It has two USB output ports into which you can plug cords connected to the stuff (phones, Kindles, tablets, portable speakers, eCig batteries, the wife’s USB chargeable vibrator or whatever) you want to charge. Plug it in, push the button (which also tells you how much charge is left in the power unit by means of 4 blue LEDs) and it will charge your device super-fast, I won’t go into all the tech specs about amps and times etc. as enough people have already covered that. Just know that it charges fast, is reliable, looks good, feels solidly built and worth its weight in gold when needed. If you’re looking for something to stick in your pocket or handbag as an emergency back up for the phone, (in case you get lucky and don’t want to wake up “your new Friend” when you find your phones died and you need to get a cab to get the hell out of there) then this isn't the one, it has a lot of power so is fairly weighty and large, this is more for the weekend/week away where you can stick it in your holdall

Great, but don't overuse.
The powercore has been a great device, although there is one small defect that I will explain. It was originally bought for use at festivals and was perfect for this purpose. The device supports fast charging and took about 90 minutes to give my phone a full charge and this would lose perhaps one of the blue charge level lights. I expected to get 4 full charges and still have enough for maybe another half typically, it could then be left to charge overnight with a festival locker and I had the ability to look after myself and friends all day. Admittedly it is quite bulky and heavy but that's the price you pay for it's MAH (milliamp hours), but you do get used to just putting it into an inside jacket pocket and forgetting about it. I found it totally durable as after 5 festivals during the season it had nothing more than a few light scratches and worked perfectly, even after some wet weather and some alcohol spilled on it. A quick wipe down and it was sound. I came to rely on it so much that I took it everywhere I went if I thought I may be away from a power point. Now we come to the issue. After a little over a year the device would no longer accept charge. Perhaps it was a fault in the usb socket or a short inside, I can't say, but after trying multiple charge cables and power bricks I was beaten. In defence I do believe the device had been used enough times to warrant a high use moniker, above what is typically expected. A quick email to Anker and after a serial number check they were happy to replace the device without hassle. They didn't ask for the previous device back, likely as it's not worth the cost of shipping. This approach may of been useful to find out what caused the fault and rectify it for newer models but c'est la vie. It took just 2 days to get the replacement and it's great to have the old friend back to rely on. Can't fault the service.

Sehr guter Akku mit schneller Ladefunktion und langer Ausdauer. Perfekt für mehrere Ladezyklen geeignet. Gut für den Einsatz für Kleingeräte zur USB-Ladung.

Meine Frau besitzt ein IPhone 7, welches bekanntermaßen nicht gerade vor Batterieleistung strotzt. Ich habe ihr aufgrund dessen diese Powerbank gekauft. Zunächst aber aber der Sinn, dass daran ein altes Handy zwecks Raumüberwachung (mit entsprechender App) genutzt werden sollte. Da ich aber nicht sehr zufrieden mit der Überwachung per Handy war, habe ich mich dann doch um entschieden. Nun war natürlich die Powerbank quasi nutzlos, bis meine Frau dann den entsprechenden Einwand hatte und sie nun dies Powerbank nutzt. BESCHREIBUNG: ------------------- Die Powerbank kommt gut verpackt und zusätzlich in einem kleinen schwarzen Stoffsäckchen mit Anschlusskabel daher. Es befindet sich dort noch zusätzlich eine kleine Gebrauchsanleitung, die aber m. E. überflüssig ist. Angeboten wird diese Powerbank in drei verschiedenen Ladekapazitäten. Ich habe mich persönlich für die mit 20100 mAh entschieden, da diese somit länger verschiedene Abnehmer laden kann. Robustheit wird im Artikel beschrieben! Dies kann ich definitiv doppelt und dreifach unterschreiben, denn mir ist dies Powerbank bereits mehrfach herunter gefallen. Es gab bisher keine Aussetzer oder Probleme. FAZIT: ------- Diese Powerbank ist absolut eine TOP-Powerbank. Sie lässt sich über Nacht mit dem entsprechenden Equipment laden und halt sehr lange. Wie bereits erwähnt, nutzt meine Frau ein IPhone 7 und kommt mit dieser Powerbank eine ganze Woche und teilweise mehr über die Runden. Für mich war es ein guter Kauf und ich kann für dies PB eine klare Kaufempfehlung abgeben. HINWEIS: ---------- Diese Rezension spiegelt meine persönliche Erfahrung und Empfindung wieder und erhebt keinesfalls den Anspruch auf Vollständigkeit.

Uso la batería para cargar el móvil, el iPad cuando no estoy en casa, no los carga en poco tiempo pero tampoco considero que en demasiado, las cargas de los equipos siempre llevan un tiempo aun cuando los cargues directo a la corriente, si hay que señalar algo es que pesa, pero hasta ahora muy bien
