My husband recently picked up one of these lovely reading lamps from IKEA. It’s 100% solar powered + works very well. The solar panel is easily removed so you can place it outside to recharge. It’s so easy that our 3 years old, actually showed me how to use it. The charge lasts about 4 hours and I’ve never had it run out-we use it mostly for night-time reading. It’s much better than using the other lamp we have which is electrically powered.
