Power Bank
I used this power bank every day, and it has great quality. It has different charging ports for any needs, and the battery life is excellent. Even after one or two years, it still works very well. I’m really happy with it.

Great Anker product
Really good speed of charge. 6 or so iPhone charges I think. If you hold the power button light goes green and lowers the output so it can safely charge smaller items like earphones. Nice design, bulky but that’s why you buy this one so no complaints. great stuff from anker as always.

A good item for travel
This item comes in very handy as somebody who relies on his devices while travelling. It's able to charge two devices at once, and supports fast charging with the appropriate cable. It doesn't support ultra fast charging, but it's good enough. It also has sufficient capacity to keep multiple devices charged all day - I used this to charge both my phone and my action camera, and on my last holiday I only had to charge it every other day. Overall a good item. The only negative thing I can find so far is that the writing which states the capacity is very small and hard to read. This caused delays at half of the airports I went through, due to the time being big, when they tried to check it was ok to travel. But this isn't enough to take off a star.

Large portable charger
Great to use if you are out and about and need to keep phone, iPad charged. Must admit I didn’t think it would be so big and heavy that’s why it’s 4*. But plenty of ports, it holds plenty of charge and it’s been very reliable.

Futuristic, powerful, reliable.
Well. They are big. Not verry heavy but not the ussual battery. Is Anker Big power. I had the previous model fir 4-5 years and they were amazing. Aaamazing i say. They do. But after lots of use they started to swllen. One of the swallen and got really hot in my side pocket while ive charged my phone. I was afraid will blow so i threw it away. Thrn after couple weeks the second one deollen aswrll. Wasnt hot. Ive put that out and is out, for three werks niw and id still fully charged. Amazing. Im so sorry that have died on me both of them. Thei were my safetty net for slmist 5 years. Good safety net Obvioudly now i bough the next model, and also two. I buy good things in pairs. Im not 100% sure thede are good as the previous model. One usb not working properly and when charging sometime the juice stops then starts again. To chatge thrm takes some time but cause they so big 20w is not a game. Up untill now they ok. Hope they be ssme goid partners as the ones before. These one loocks futuristic. I like the hold of them. To hold so much power in your hand gives you confidence. And that feeling is great. The loock is absolutely cool. Love it. Hope yhey eill ladt 4-5 years aswell. Later edit. Ive used them after i git them and i gotta say, im dissspointed They dont last long. After a full charge of my A55 and another short charge 20 % charge batery is less than half so my phones battery is 5000 mah i suposr to charge my phone kets say at least 3 times if nit four. But these takes 2 charges and is left jus a bit in it. The cables came with are giveme erors of conections in my phone ir just stop charging. Also one charging port not working or eorks a bit then stops charging my phone. Bith have issues. I ferll i can cry 😭 im soo dissspointed. I had those befire this one, and werr abdolutrlly amazsing. After 4 years started yo hest up and yo swollen. One of yhem swillen and ive put it out. After mire thsn a month and a hslf in the cold is still full. Ehich is imoresive. Wish these ones be good like the midel before but, sadly are nit. I had those before these aaand those before thisr. Do i had three generstions. 2 each. I still have onr of the first modrk. Still great. These ones, ladt midrl, veeerry dissapointed. And i got two of them. I dont wsnt to srnd them back, but i have no choice. I need good battery.
