20000mAH can be too much for some people but it is necessary for a heavy user. Either for daily used or using it for a vacation. Xiaomi Mi 20000mAh Power Bank is made from China, so it's affordable in price and for its product quality, the housing is anti scratch, xiaomi provide two ports to charge both simultaneously, comes with built in micro usb, charge up devices 5-6 and 7 times in a single charge (takes up to 8 hours to charge power bank) auto on/off when you connected/disconnected a device, it carries 358g weight, double in weight compares to Samsung brands which at 150g only

It's a durable power bank i can say, sturdy yet not bulky, a great build quality you can just feel it, some really love this powerbank by its shape, it's thin in size, easy fit in pocket, so lightweight, it's a convenient power bank for travel anywhere. Just put in any pocket and there it fits. This powerbank comes with built in short microusb cable attached to it. Regardless, pineng provide two output to charge your phone and both is rated at 2.1 A, so you can go ahead and charge both at the same time. They also considered a usb port to charge c ports, for users who have type c phones can just bring the cables, consideration is essential. The powerbank uses li-po battery technology for those interested in good quality battery. This powerbank also provide the lightning connector for an phone user, in my experience it can fully charge an iphone SE about 4 to 5 times in a single charge. Been using this over 2 years it is still juicing my device, I have accidently dropped it lot of times and it still going strong. I will definitely recommend this powerbank to my family and friends.
