Power Bank 20000mAh 4A 2-Port Input, VIVIS Ultra High Capacity Portable Charger 5A Output 2-Port Li-Polymer External Battery Power Pack for iPhone iPad Samsung HTC Smartphones Tablets

Very good product, after a few months of usage I am very pleased, saved my iPhone many times. It also charges fast in a couple of hours when using dual micro USB charging. It is also light and stylish.

This portable charger charged my s6 very quickly and only went down 1 led light. It charged my ipad air also quickly and went down around 85%. When charging this power bank it is very quick took around 10 hours with the input and around 5-6 hours with both inputs. However it does get quite hot, not too hot but noticeable. With such a big battery of 20,000 mah you can take this anywhere and just charge your phone on a plane, car etc, you should not have problems with this battery running out.Pros:Good batteryQuick ChargeComes with a BagComes with cablesCons:Gets hot while chargingExpensiveOverall this is a great product that I highly recommend you buying!

Great piece of tech! Charged my IPhone 5 about 8.5 times before running out of battery it's very good looking and was very quickly delivered despite a long estimated delivery time. 100% reccomend this!

I believe this is a genuine item. Ran some test and worked as stated with an older samsung s3. Placed in a blu xls2 phone and although slower, works fine for video etc (small files appear to take a long time but large video files are much quicker in transfer from pc). Would buy again from supplier. Well packed. Nice presentation case and two leads.

This worked great for about a month, but now it just doesn't retain any charge. I've been charging it all day (since 8am and just took it off just before 11pm) and it's only got 1 light battery..This was not the case when I first bought it so now I won't be able to fully charge my phone with it like I was able to in the beginning.

Awesome first proper power bank the price is a real steal you defo need to grab this power bank if you really need one

SUPER SELLER, GOOD PRODUCT

bad quality, I bought it a month ago and already doesn’t work as it should, it is slower to charge the phone and now after being in charge for 12 hours as soon as I turned it on only two LEDs lit up. I'm really upset, I have to buy another one after I spent £ 25 a month ago.
