Hi guys, I am sharing my 7 months experience about Corseca power Bank 10400 mAh.Its an awesome power Bank. I bought it in 4 December 2018 from Amazon for the cost of Rs 1400/-.It is working well. I don’t care if the electricity supply turned off for three or four days. Because it’s 10400 milliamp_ hour.Dimension is 17.2 x 10.6 x 3.8 CM. Battery cell composition is Lithium lon. I got 1 year manufacture warranty. It has two slots for charging.Design is also awesome. It gives true value for money. I like this and strongly recommends it.
