Does it has power already?

That is a negative Red Rider. This tower does not come with a power supply.

yes, it has enough juice to power it, just not sure for how long. my guess would be several hours. but most tv's have a usb plug in the back that is good for powering it on. it's what I do with my chromecast.

Yes, I just plugged ours right in. It's a little power brick like you've probably seen before, not just a plug though.

Mike: Yes to both your questions. It's very convenient so you always know if it's powered up or not.

No, and don't waist your time & money on it. It's a piece of junk. Unless you continuously wind it every 20 minutes, it never has enough power to do anything.

No. It has to have power, and then be turned on with the remote or button on the unit.

It should already be on full power. But press "power" and keep pressing it to change the power.

It will power and/or charge the device(s) attached to it. Great backup power device.

No, and the battery lost power so fast, I nearly can't use it. It's keep in some drawer in my closet!

Technically, the answer is yes; it gains its power externally--it has no internal power source. However, in common parlance the answer the answer is no, since it gains its power through the usb and does not have a separate power cord or connection.

No. It runs on battery power which is recharged by either solar or hand cranking.
2042045
No. It is powered by the receiver and needs one of the ones as WiliWali already mentioned.

I believe it can, same as being connected and not running on battery backup.
1649969
No, it runs approximately 1 hour and a half. Then you have to plug it into power
1510650
Yes it will power, it's a great unit , also look at the inputs on unit, should be able to connect to virtually anything

I don't think there is supposed to be power there, I think it is only supposed to switch power you bring in. I'm not positive, but that is how I'm using it.
