In the past few years, we have covered plenty of decent solar chargers for iPhone and other comparable devices. The ECOeshiner 24W Foldable Solar Table is also worth a look. It has a lightweight design (1.8kg), so you can easily take it with you anywhere. It also comes with 2 x USB 5V charging ports. This table can handle 10kg of load.
This solar panel is IP65 waterproof. It can be set up in 3 steps. It has a 1200D Oxford waterproof fabric and is splash & rain proof. This table also has a compass and thermometer. You can find out more about it on Kickstarter.
