As a professional photographer, I take my Jackery with me on location. That often means in the middle of the Pacific Ocean. I photograph regional, national and international sailboat races, so I'm often in the middle of the water for up to 13, 14 hours, or longer. Jackery never lets me down. And my race committee members can also connect to charge phones or laptops, so we can get photos and scores sent back to mainland HQ sites to be ready for awards at the end. It's great for wedding locations to keep my strobe and camera batteries charged. They're long lasting and durable. I wouldn't go out on location without them. Yes, I have TWO. Everyone around me always thanks me. (You're welcome.)
