It is a very useful product while traveling and never let you run out of battery until you reach your destination. I have MI note four which have 4000 mah battery and this could charge it 2.5 times. 4000 mah can work for the whole day even while using the internet. It means that I have 3 days backup easily if I fully charge my cellphone and the power bank, and thats a good deal.
The looks are appealing and weight is also light so we can carry it for hiking without carrying some extra weight. It gets fully charged within 3 to 3.5 hours and it has two ports for cables and we can charge two mobiles simultaneously. Yes, this product is definitely value for money and you can go for it.
