I love Anker products, they've been on top of their game for a long while now. This is a great power bank. It is slow to charge, but this is obviously due to it's high capacity, so just be aware of that. Only complaint is that the capacity is not 20,000 mah as stated. I'm getting just about 17,000 mah on my meter, several attempt to drain the battery completely and recharge have all yielded the same result. You'll lose roughly 20% during transfer of energy, so you leaves you with about 13,600 mah. Another thing to be aware of, doesn't take away from how good it is.

My cousin love it. it's good to bring in hiking and other outdoors activities.

Looks like good item but never opened box. Item received too late too put to use during 3 day power loss. Returned item.

This was a gift for my grandson, and it was exactly what he wanted. Fair price and arrived as promised.

As an American who loves American made things... China rises to the top with Anker. This battery pack is great and compared to other 20,000 this feels double their battery life. Very reliable pack charges great and I've NEVER had an issue with an Anker product. Would highly recommend picking a few of these up if you want a good battery pack.
