Power in transit

My poor iPhone battery won’t last the entire flight to Shanghai, especially if I watch movies and write notes for 22 hours. I’m not wild about plugging it in to foreign outlets, even with international adapters, so I’m traveling green with two Solio solar chargers. Hopefully the sun will appear through the smog, but I can also charge the Solio from a USB port. Each one will give me an extra full charge for my iPhone. I’m hoping this will solve my iPhone power issue for the entire trip. I’m not as worried about recharging camera batteries.
