It appears to not have a battery pack. does it have to be plugged in, and if so, how can it be made mobile?

The battery is housed inside the device. To the right of the antenna theres a plug to charge (9-12VDC), it takes twelve hours to charge for the first charge. Every charge thereafter is four or six hours (double check instructions). The device is mobile. Its a good battery, I've only charged it once, I havent needed it. Maybe a handfull of places I've actually swept a specific area and ive had it for eight months. I wouldnt leave the device plugged in the wall too long after its charged, you'll decrease battery life.

You will need to plug it into a wall outlet. There is no battery to charge.

It doesn't require batteries. It must be plugged into an electrical outlet.

It has a power cord that you use to charge it and I believe if you use it while plugged in, it doesn't uses the battery. You can us it with an iPhone ( or any MP3 player/smart phone) but I highly recommend purchasing a cable with a 1/4 inch jack on one end and an 1/8 inch on the other to run music through the "aux in" instead of the designated iPhone slot. When you use the iPhone slot you receive a lot of static with the music but you get none if you use the "aux in" imput.

No. It needs to be plugged in since there is no battery pack on the controller.

I use mine plugged into an electrical outlet, but it comes with a AA battery in the transmitter that can be used for portable use. I cannot verify how well it works, but the battery in the headphones and transmitter should be fully charged for best results.

There is no battery pack, it's a solar panel. You must have sunlight for it to charge anything.

There is no battery with this machine. It has to remain plugged in to be used. Think of this as a desktop machine, not a laptop or tablet.

It can be plugged in. I leave it plugged in in my office and only use it as a tablet when using it in other rooms or on the go.

No, it has to be plugged. You must get a lot of voicemails! Good phone though.

The unit is not equipped with an on board battery, it can't be "recharged". You just plug it into a house outlet or an automobile port for use.

It must be plugged in to work. It is an inverter, not a portable power pack.

It has a plug. It also has the ability to run on batteries, but I don't know how long the charge would be since I keep it plugged in.
