Yes there a many different plugs that fit into what ever electronic device you are trying to power so you do have to pay a little bit of attention. Most solar power chargers will have several adapters tho. A lot of manufacturers have moved to a USB to device cable which simplifies things somewhat. The hand crank charger that came with the eton radio has a USB charging outlet. I can make that work with my Tundra phone, the Ipad or the kids ipods or DSsssss.
