Portable chargers are great for peace of mind whilst on the go – unless you forget to charge them. XDModo have fixed this by creating a device that uses solar energy, so you can charge wherever and you’re not draining any of the earth’s resources either. The ‘Window Solar Charger’ sticks to glass so it can soak up the maximum amount of energy possible, or it also has a handy kickstand. Pretty essential for festivals and holidays!
