This is another common question and will depend on the charger you have or want to buy. Some solar chargers are only suitable for a small range of gadgets, so its hard to give a direct answer - you will need to check the manual or manufacturers website.

However, if this is a priority for you, you should look at getting either a powermonkey charger or solio solar charger. Both of these come with a range of adapters which will fit nearly every cellphone as well as most other common devices you may have.
