If I don't plug in the HDMI port, can I still use it as a fancy travel charger?

My experience has been that this charger is slower to charge than others. So it will work, but I would not recommend it as a travel adapter. However, I've always had it plugged into the hdmi port, so take this answer with a grain of salt.

I haven't tried it that way, but I do use the charger as my main charger daily (w/hdmi plugged in).

It is supposed to be plugged into the same place as the charger. If you have an Acer or Asus tablet, however, nothing will make it work. It is, essentially, a case of false advertising.

Power is required, but it does not come with a power adapter. This HDMI converter does come with a short USB cable where it draws power from. You can plug it into your laptop or other USB power station for power, we use our iPhone/iPad power supply with it. Note that is absolutely DOES require power (it won't work without it) - but it's very little power. If you need an adapter, any inexpensive "wall wart" with USB jack will suffice very nicely. Note that the preview images do not show the USB port on this box, but it is there on the side. You can use a longer USB cable as long as it is a "Micro USB" plug, similar to what comes with an Amazon Kindle, etc. (in fact, if you do have an Amazon Kindle, that USB cable and wall jack will work perfectly). Edit to add: by the way: This is an EXCELLENT HDMI converter. We are extremely happy with it and when we need more, this is the one we will buy.

Yes. The ports correspond to wattage output. Using the wrong port would cause a higher watt device to charge slowly or a lower watt device to overheat.

Depending on the manufacturer of your tablet (unknown) and the fact that the HDMI cable is not normally used to supply power to a appliance, I would say NO that you cannot. If you can't find anything in the tablet's manual referring to the use, then I would contact them for a final answer on your question. Sorry to be of so little help.

From a electrical standpoint yes, but you have to think, the power input is 2 amps, that's what your phone uses to charge, USB drives can take up to 1.8 amps, HDMI take about .1 amps, so you could be charging off of .1 amps (which wouldn't provide enough power to power your screen), I would recommend that you use a powered dual usb hard drive(the one with two cables) plug the power cable (usually the smaller one) into the wall.

No--but it may require an adapter if you are traveling abroad. Works great.

You can use your laptop usb to charge it or any wall usb outlet you use for your cell phone. Keep it off to charge faster but you can watch movies indefinitely if it's plugged in. There's 4 indicator lights that stop blinking when it's fully charged. I hope you recieved one that's not doa! Good luck!

Yes. You absolutely can. I use it while I'm traveling and it is the only charger I use while traveling. I found on a couple rare occasions I had the device switched on and it didn't automatically turn itself off and didn't accept the charge from the wall. Most of the time I don't have this issue and it recharges the battery as well as my connected phone and other devices.

This passively converts the display port to HDMI. It will not plug into your USB port.

This device does not require a power adapter. The limited power that it consumes is delivered via the HDMI input.

If there is, it's by no means accessible to the average consumer. The clear answer is no. You can charge this through its micro usb port and then have it ready to power an electronic off the (full-size) usb slot when needed on the go. If it dies, you get a new one. If that's a concern then get a better, more expensive one.

No, unlike the USB portable monitors that do. This one connects to the HDMI and uses the USB for power only. I even used this on my android tablet (has HDMI out)!

No I don't know of a charger that will let you use an hdmi.This charger is a great charger

Some few devices are non-standard and their HDMI ports are not powered. In those rare cases an AC adapter will be required. I found all the devices I use, except the cable DVR box, worked fine. I requested an AC adapter from the seller and they sent me one, free of charge.

No. It is a Micro HDMI on one end, and regular HDMI on the other. This will not plug into a USB port of any style (micro, mini, or regular)
