Scosche SolChat solar-powered Bluetooth speakerphone

The more gadgets we bring into our cars, the more cables end up strung down to 12-volt power points. Scosche's SolChat eliminates one of those cables by getting its power from the sun. The SolChat is a Bluetooth car speakerphone that lays claim to the "green" label by being solar powered. It's also one of the better applications of alternative energy in a consumer device that we've seen to date.

When you first get the SolChat out of the box, you'll want to charge it using the traditional, corded route (a USB charging cable and car adapter also ship with the device). We initially charged the speakerphone via a USB port on a computer and it took about 3 hours to fully charge. According to Scosche, with a full battery you should get up to 12 hours of talk time and up to 450 hours of standby time. But if you leave your car out in the sun--and have the SolChat affixed to a visor or the windshield--the little solar panel on the device's backside collects sunlight to continuously charge the unit's internal lithium ion battery. A windshield suction-cup mount and sun visor clip are included.

What's nice about this setup is that as long as the sun is shining, you'll be able to just leave the SolChat attached to your windshield (or visor) and not have to worry about having any cables running to the cigarette lighter in your dashboard panel. And at 3.5 inches by 2 inches by 0.5 inch, it remains pretty unobtrusive; it's not much bigger than the registration sticker you affix to the inside of your windshield.

The SolChat has some built-in voice features, including "voice announce," which is the equivalent voice caller ID. However, to use this feature and have the SolChat announce a caller by name, you have to transfer your contacts (via Bluetooth) from your cell phone to the SolChat. Note: Not all cell phones offer Bluetooth transfer of contacts.

If you don't have the caller stored in your SolChat, a recorded female voice will simply say, "Incoming call," and start saying the incoming number when your cell phone rings in the car (you touch the main button on the speakerphone to accept the call or hold it down for three seconds to reject it). This model also supports voice dialing so long as your mobile phone supports it (and you have it set up with the contacts on your phone). To voice dial, you tap the speakerphone button once and say a contact's name to have your phone dial the number.
