How does this.. like... charge? How does this thing get the power to send its signal?

The keyboard has an internal battery that charges via a micro USB port on the side and it connects to a device via Bluetooth.

One unit (the receiver) has a USB cable. It must plug in to a powered device that has a usb port. The cable does not charge It, just keeps it powered. The other unit (transmitter) plugs into a normal 110 outlet

Yes, I have it plugged into an electrical outlet.It does a great job of boosting the signal.

Its powered through the coaxial cable. It works immediately after you hook it up, not days later.

It sends/receives the signal wirelessly so the only power is from the alarm unit batteries. It works and it nice not having to worry about looking for an outlet.

I ended up throwing that one away because I needed one that sent a signal to the receiver from the computer and it does not do that. It seems to work only from a component to the computer but not out of the computer. Hope that helps.

Not that I know of, or at least it's certainly not a feature present out of the box--it only charges via USB. I don't think it has the ability to send data through its micro USB port, only to receive power.

It depends in how good the signal is. If it's spotty, the battery won't last. You can get a charger for your car. It uses a regular mini USB cable.

It comes with a small power supply. Just plug into any house wall socket and it will charge the unit. On the front of the unit there is a series of lights. Red Yellow and Green. To check on the charge push the small yellow button next to the lights. If you have a green...it's fully charged.

It doesn't charge, it's an inverter which means it uses your car battery to run electronics that would normally plug into your home outlet. It only works when connected to a car battery.

It does not provide power to any device. It is powered but does not provide power (other than through the USB ports)

You have to think it backwards - this unit GETS power through the USB port. So, it can't charge something because it doesn't have power to do so. The question could be "if this is connected to my phone's usb, will it provide power to the mixer to make it work?" - and even so, the answer would be no. But it needs power to be directed TO it via USB.

It's not battery charging style, it gets power once it's cord has been plugged into socket. To make it works properly, please make sure you hold it in a right way. You can google instructions for details. Good luck!

It requires micro usb to power it, I was converting a signal from my computer, so I plugged in a USB to micro usb Cord to the back of the computer. If you dont have usb power available, then you will need some sort of adapter.

Every time you setup it needs to be powered. But once you have signal you can disconnect power to it

The power comes from the device(s) hdmi cord(s), there is a power supply plug available on the splitter, but it is unnecessary, so they do not send one, this device just works it's wonderful!

There is a designated port that you plug in a device that you want to control the power. When that"controlling unit" draws power, the strip senses that and then turns on the power to the other outlet.
