Can it be used in a hotel room or only in car with car adapter?

You can use them anywhere as long as you have a ac adapter or a 12 volt power supply.

There is a DC in: 9V, 1A input. I am unsure if this cord is included standard with the item or not, however, they can be purchased very cheaply online (1-5$)

It works and is great to use inside when the connection for a car is not convenient!

It can be used in any vehicle. The suction cup works very well. Make sure you have the right docking station compatible with your phone because its also a charging station as well.

No, It can be used in a car or at home with the kit. At home, it has to be connected to your stereo to get sound.

You can use it in a car seat, only if you have an electrical outlet in your car. The chair has a plug that needs to be plugged in to work.

This will work in any car or you can wire it in and talk at the bar. You could use it on a boat out for a float, and even a landlocked sailor can use it in his tiny house travel trailer.

Yes. I have used mine in both my office and in my car. Works great! Plus you can use the heat feature with and without the "massage" feature (which is really a gentle vibration).

I use mine in the car all the time. Your radio needs to have an auxilary input port. Then you can use a 3.5 mm male to male cable to play it through your stereo system. For long trips you might want to get car power adaptor.

I used it in my car, but the unit that it is connect to has another connection specific for iPods/iPhones. It works fine for storage devices so I think there should be a problem for what you may want to use it for

No I'm sorry :c i thought it plugged into the wall that's why I got it but no, it has to be hooked up inside of a car.

It has to be plugged in.The typical use case is to be plugged into a USB port in your car.

I use mine just to charge at home and in the car, still need to use ear piece or headphones, my car is not equipped with the adapter to put through speakers and thus set us just charging

we planned to use it in the car (12 volts) during daytime driving and then plug it in with the AC adapter at night in hotels. We found that the AC adapter was noisy and got scary hot in hotel rooms so we just quit using it that way and anyway the hotel room usually had a fridge. It takes a couple of hours to cool off when used in the car, after that it keeps cold for the rest of the day. It should work for you that way.

If you have the adapter for regular plug in, it works fine. (Without the adapter, it only plugs into a car.) I bought the adapter separately.

I use it all the time in the car while we are moving, but for camping, unless you can recharge your battery, it needs the adapter for electric use. Car battery would only last a short time.

It could work in a car but I wouldn't use it as a car charger. Your phone would just slide off.
