I just got a very special smartphone casing for my Samsung Galaxy Note 4. This casing is not just a casing because it has a built-in 4800mAh power bank. So the convenience of having a built-in power bank smartphone casing is not having to lugged a separate bulky power bank while charging the smartphone. Before I order this from eBay, there is not much reviews that talks about the details of this casing that matters to me such as "Will it have data connection while the phone is using the casing?". Most of the reviews are un-boxing reviews which are rubbish. Below is the list of my findings on this casing and hopefully it will benefit anyone who is planning to buy this.
Anyway, I went ahead and order this casing out of necessity where my Samsung Galaxy Note 4 battery will not last me through the day any more after due to daily recharging for more than a year.
