Reliable and great capacity

20000mAh is a great capacity to charge my iPad Air, Samsung Galaxy S7, GPS Garmin, Sony Camera, MP4, BOSE Soundlink Color (

It has great capacity and got heavy use to charge two phones, a tablet and a mobile hotspot on a recent trip.

While a bit heavy, it has a great capacity.

Weight: it feels little bit heavy, I have not paid attention to the weight while buying, but I have nothing to complain, as you can see in the description they have even included warning next to the weight information saying that this unit is bulky... trade-off is capacity of course, this unit is 20 000 mAh, which is great capacity, but for everyday usage and easiness of carrying with you, I think 10 000 mAh version of this device would be more optimal, which is also available on Amazon Yoobao A1

You won t' regret it
