What type of fittings and adapters does it accomodate?

It comes with a plug that has a regular (full size) on one end and an USB mini plug on the other (with an adapter that goes to micro usb (standard on most new non apple phones). When charging the internal battery the full sized usb plugs into a computer or wall charger and the mini end plugs into the unit...then when using the unit to charge a phone or mp3 player the full size usb plugs into the unit and the mini/micro end plugs into the phone...This sounds confusing but it makes sense because this way they only have to include one cord that will allow it to charge from most power sources and charge most small device. I've had my unit for about a year and bring in on camping/travel trips. The internal battery (when charged from a wall or car outlet) is strong enough to refill my cellphone battery 1-2 times. The solar panel on the unit is enough to trickle charge my cellphone with enough power to make a phone call after several hours of charging (tested at home not in the field)...If you are looking for something with a solar panel big enough to recharge your phone/camera battery on its own on a daily basis (long camping trips) you need to look somewhere else and be prepared to pay several hundred dollars. If you are looking for something to take with you when traveling or on short camping trips as an emergency backup then this is the way to go. Sorry for the long rambling response, but I feel people are giving this a bad rap because its purpose is not clearly understood (or labelled).

Hey thanks for expanding, Lyric. I'm not big on referring or linking the competition's sites either, but when I saw that, it would've been a real disservice to Jeff not to bring it to his attention. Reviews like that are tough to get around. At least we now have a point of reference to begin some solid feedback here when called for.

All it apparently has is the mini-usb plug. Brunton offers nothing else at this time, but says that it will power any type of handheld electronic device, from a GPS, cell phone, or i-pod... I can only assume that this means that you'll have to find a proprietary usb adapter from the manufacturer of the specific device you want to charge, if it's required. Before you decide, you definitely want to read the few reviews on this from REI. Sorry I couldn't be more helpful, but there's nothing that I can find more specific out there beyond what I conveyed here...not even from Brunton.
