To keep your gadgets powered up on the go, which brand of power bank do you recommend?

[LoveApple]

Hello! everyone. The battery life of many mobile and camera devices isn’t that great. I always find that my phone has died halfway through the day,so I continue to explore the available options for external charging of our phone. Which brand do you prefer when you go fishing or on a trip? Is there anyone can give me some advice on that? Many thanks!
