I bought a huge Anker a year or so ago. It has dual USB out. I think it's something like a 20,000 mAh battery or so. Specs say it'll charge a big phone from empty around 5 times. I bought it for a Disney trip with friends. We were using our phones VERY heavily with the Disney app to manage fast passes and navigate the park and whatnot and I kept 3 phones up all day with it, with juice to spare at the end of the day, when I'd top it up for the next day.What are people using? (Dual USB out, ideally)
There are obviously different options at different price points, just looking to be able to keep my phone/headphones powered up for 10 hours or so.
Thanks!
