There are a lot of external burners that plug into the electrical
outlet. That to me is better than using the usb port for power. Try

Thank you again! I looked at this burner at Newegg, and I'm
confused. If this is a burner that plugs into an electrical outlet,
how do you know that? I couldn't see anything in the specs about a
power supply... Jo-Anne

Look at this picture of it.

Thank you, Bob! Now I see it. But shouldn't that be something they'd
mention in the specs?

Although I have seen external hard drive enclosures that don't need AC
juice (then again, I'm pretty sure they still all have that option), I
would imagine that there is no such thing as an external DVD burner that
wouldn't require an AC connection.

Hi, Daave,
I've been told that many (most?) of the external DVD burners get their power
from two USB ports rather than from an AC connection. Some people have said
that theirs work OK with only one USB port.

I find that surprising!

I think the slim drives run on 5V. The claim here is that it is bus
powered.

The picture on Newegg for that drive, shows it has a "Y" cable for
USB. And that allows 5V at up to 1A to flow. One USB connector is
just for the power pins, the second is a full connector with data
pins. Being miserly on power, means a longer spinup.

*******
The desktop versions run on 5V and 12V, and draw more current from each.

They're a different design. The desktop version definitely needs a
power brick. I've measured mine and it draws 12V @ 1A when running
with media in the tray. The label on my desktop drive says it draws 1.5A max.

And things like desktop Blu-ray drives draw even more current. Although
those numbers seem to be dropping on the latest ones. They're getting
closer to the other CD/DVD drives. I think I've seen one earlier than
this, that draws 2.5A max.

Power Consumption 5V @ 1.1A, 12V @ 2.2A max
