A solar powered phone charger is a cool gadget that’s useful and eco-friendly. If you’re looking for a good white elephant gift that’s not just for laughs, you may want to have a look at these. They work great on long car rides, on airplanes, and home or office windows. They may also be handy for spending time outdoors at the beach or in the park, particularly when using a phone to play music, watch movies, or for other battery draining activities.
