Ionbank 3K (2017) / Iongo 5K (2020)

Through observation, we notice one big issue of the power banks is that people often find it low battery when they need it. They seldom forget to charge their phones but their power banks. Hence with a built-in charging/data cable inside Ionbank 3K, it can be charged simultaneously with the user's phone connected with their computer or power adaptor.
Unlike many others covered by a metal shell, Ionbank 3K's cover made by vegan leather to prevent scratches when held with a phone in hand or put in the bag.
