Is the eGo USB Passthrough safe to run in a USB port of a computer?

[breakfast]

I have a mid-2009 Macbook Pro and I'm wondering if the USB passthrough eGo would be safe to use.

Thanks

I don't know about the eGo-PT in general, such as the mA it draws for charging, but if it is 300 mA or less you will be likely be fine. Most computer USBs are rated to 500 mA. This all said, it is generally considered smart to only use PTs on either a powered USB hub or an AC/USB-5V converter that plus into a power outlet. That's what I use. I have fried ports and also USB cables with PTs, even original 510 PTs. If I had a Macbook Pro, I would not want to risk damage unless I knew the ratings of the ports, and the current draw of the PT.
