Wingard portables require a 12volt external power source. How does this operate without the power source?

This TRX_HD is using pwoer from normal USB power adapter directly without any battery inside. It is very useful and convenient unit and design.

No man, it doesn't have an internal battery sadly. By portable they just mean self contained. Its quite heavy though. Slightly awkward to lug around. Great speakers though. Definitely worth the price tag IMO. You will need a 110v power source to operate them at all times though. You can run it on a car battery with the 12v adapter. Gotta leave the vehicle running though or it'll drain it fast.

Ron....no, the hard drive is a plug-n-play, no external power source needed.

Hi. With this device, you do not need any external power. The device brings it all included and takes what it needs directly from their computer. It works excellently. Regards. Vincent.

There is no external power supply. The phone line and the batteries suffice.

It has no internal power...so I guess if it's worth it to rig a 12 volt external power pack and a goofy helmet with a special mount for it or....just get a GoPro or other portable unit. That's what I use.

Paul Buff "Vagabond" regular or mini works well.. U don't need a large power supply.

No external power required. Only needs a USB port with enough power. Most standard USB 3 ports should be adequate.

This unit MUST be plugged in to operate. Unfortunately it does NOT contain a standalone battery.

It is powered by the phone line, no external power supply. The old fashioned basic type!

It will function without external power. Using external means there is less drain on your (Laptop) power.

It is set up for a standard 110v wall plug. It does not seem to use much power so to make it portable you could use a 12v battery (even a small one like the ones on kids toys could be strapped to the side) and a power inverter.

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

The power source is a little circular 3V internal battery. It is included with the device. There is also a light receiver on the face of the device that I assume contributes to managing battery power.

No, there is not an external power source included, it only comes with a USB cable. However, you can connect this USB cable to one USB power supply that can be connected to your +12VDC car adapter, they are very popular now.

Powered by USB port, no external power adapter needed. This is a very good case and is still working great for me.
