Slim, portable and a good overall design. Well done ANKER! 10,000 milli amps is enough to charge my Samsung A53 5G about 3 times from 0% to full.

5.0 out of 5 stars An Essential Item in this Modern Day and Age - Buy It

P. · 16 August 2020

Still rocking a Samsung Galaxy S6 and even though I personally replaced its battery with a genuine replacement. I seem to find that with its internal 2500mAh battery it struggles to provide power for the phone when i am out and about and away from a charger for the day. With my usual daily routine, I commute by car to work so the phone is always plugged in charged whilst navigating and when I am in the office the phone is occasionally on my wireless pad charging.On days where I am away from the charger for a day you really have to be careful with how you use the phone.Some will say, just buy a new phone, however even new phone's battery capacity average around only 3500 mAh which will struggle to provide a day's worth of powerThe exception maybe perhaps the flagship like the s20 ultra with its mega 4500 mAh battery. However this phone is over £1000 so out of most people's reach.I needed a battery bank for those extended periods away from the charger whilst being reasonably priced too.There are so many offerings out there, however being lithium Ion battery technology there are many safety concerns.If the internal battery is poorly managed, it can result in overheating and exploding batteries.This is where Anker springs to mind, after reading many reviews, their battery banks seems well priced and very reliable.I opted for the 10,000mAh version, which comes similar sized to the actual galaxy S6 phone.With its capacity, it can charge the phone 3 times, therefore perfect for those extended periods away from a charger.I managed to wait for one of those offer days and bagged it for £17.Upon arrival, I was very pleased at the build and quality of the battery bank. It comes very nicely packaged too.The included cable is of great quality and not a cheap Chinese cable that will last a few weeks.It also features a small LED indicator showing its current charged capacity which is a nice touch.The bank also featured power IQ and voltage boost charging. This was very noticeable when charging my galaxy S6, it charged much faster than the original 2 amp output wall charger. This was quite a surprise.I have now used this on many occasions, and it is a godsend from those extended periods away from the charger.It can also just about fully charge my Samsung tablet (TAB S - t800 model), this tablet has a 8000 mAh internal battery.Pretty impressive.Granted it is alittle bulky to carry around, ideally suited to place in a jacket pocket in winter.However during the summer periods you literally have to pocket it in your jeans, but being pretty slim its not too bad and worth it considering the benefits it gives.Purchased in De 2019 and still going strong to this day (Aug 2020)You can get various versions for your requirements, micro USB, USB C version and lighting connector version for Apple.They also do smaller versions if you feel this type is abit to big.A great reliable brand and a highly recommended purchase.

Very handy, portable and good size with the ability to charge my product semi quicky. However the power bank itself does not have a good battery life so struggles during heavy use.

5.0 out of 5 stars Lightweight and powerful enough for my needs

R.B. · 19 December 2024

Used to power a Roland D-6 synth on stage and does the job admirably. Charging times are not the fastest but for my use case, being lightweight, good quality and reliable are essential - it fulfills this role excellently. I can rock it up all night on stage without any worry of power loss nor mains hum from a power adapter plugged in usually to extension leads carrying power to everything else. An absolute gem for me. Cheap too and of course Anker quality - I wouldn't buy any cheap chinese power banks for running thousands of pounds of synths. I have multiple Anker products now - they have become my go-to due to the build quality and reliability. This thing is a great addition.

Small, well made power bank. Only one output but that’s all I need for my phone. I’ve got Anker power banks from years ago and they’re all still working. At this price they’re a bargain.

Compact

Signora powerbank per lavoro

d.c. · 3 January 2022

La mia salvezza quando lavoro in giro, ricarica praticamente qualsiasi cosa quando sono in giro (tranne i PC, ma in alcuni casi fa da mantenitore di carica con piccoli PC) affidabile, bella da vedere (anonima, non da nell' occhio quindi perfetta). I led non danno fastidio al buio, ricarica veloce. Ho Anker per powerbank e cavi da più di 6 anni. Presa, pagata 10 euro in più di una powerbank di altri brand ma veramente consigliato l acquisto

Perfecte powerbank

Ideaal voor mee op vakantie. Hij ondersteund ook snelladen!!

Funcionamiento perfecto

M.F. · 11 January 2021

Llevo mes y medio con él, y por ahora sin ningún problema, funciona perfectamente. El único inconveniente es que uso el cable de mi móvil para cargarlo con rapidez. La carga rápida es del mismo tipo que trae mi móvil, no es carga tipo Qualcomm Quick ya que es incompatible con él, tal como se indica en la descripción del producto. Pero si se carga con la misma rapidez que el móvil, el mío tiene 4.000 mAh, y tarda más de una hora en cargarse, esta batería Anker tarda más de 3 horas en cargarse totalmente.Tiene una función llamada "carga por goteo" para cargar otros aparatos que no admiten una carga rápida, como pueden ser los auriculares por bluetooth, para activar esta función hay que pulsar el botón con los leds en azul hasta que el primer led se ponga en verde. En mi caso esta función se apaga cuando la carga del cargador de los auriculares se completa, esto suele ser antes de 2 horas, de este modo no se dañan los auriculares.Estoy contento con este producto y por ello lo recomiendo.

Great
