It has a USB cable that can connect to your computer, and I have a PC not a Mac, but no power cord.

It is not battery powered it is mains AC ,I connect it via USB to to the 10w USB power adaptor that I use for my I- pad2. The adaptor is 100-240v - 0.45A. output of adaptor -5.1v @ 2.1A , this works very well. I have also connected it to my Acer notebook via USB and that also works very well (the USB connecting lead and a power adaptor are included with the scanner as a standard accessory).....hope this helps.

Hi! Happy Mac user here - and YES - you can connect it to your Mac via USB. If you want to use the USB port to power the scanner (totally do-able!) then close iPhoto while you scan. If your settings are set to auto-recognize any camera connected, iPhoto will attempt to access the scanner, however you can't use it "live" (with the Mac as a preview screen) but it makes importing quick and easy from the SD card.

No, it has a 120 volt power suooly with a USB connection. It works fine on Windows Vista and 8. Can't comment on Mac. Hope this help.Art

No battery. The power source is a regular power cord. I am not a Mac user so I can't answer the Mac question. But I will also add hat I have scanned more than 5000 negatives on this since I bought it and it is still working great and I absolutely love this product!! I scan to the SD card then transfer to my PC periodically. ( I was scanning by year so I would transfer when I finished scanning all negs for that year)

Power source is not USB. Comes with 12 VDC power adapter. Has two different data interfaces: USB 2.0 or eSATA. Use either one at a time, but not both. I have found the USB interface to be more reliable, although a bit slower, but not by much.

Uses 3 AA batteries. How long it lasts - who knows - I power mine off a USB port connected to my Imac.

It runs through USB when using it with a Mac. You need the power adapter if using with an iPad.

No, the only ones that work on macs have an external power source (like a battery pack) or have a USB plug.

This unit is powered by the USB connector on your computer. No external power supply.

It is AC only. It just has a basic power cord. I really do not know why they call it portable, since it does not take batteries or charge with internal battery.

No. Just the USB cord, which plugs into a port on the computer. Works fine, except for my Apple super-drive burner. I guess that requires direct connection to my MacBook Pro.

Just connect usb from charger to Mac air to charge, will probably only be good for 1 charge though, laptop needs more power than the smaller devices obviously.

"We provide the USB cable that's not only the interface connection, but the power source - no additional power cords are needed." as per product description. There is no battery power.

The cords it came with are the only ones that will power it. I tried hooking mine to my computer and lap top and it didn't work.

It should work on any Mac that requires 85W *or less*!!! Just because the power supply is *rated* at 85W doesn't mean it delivers that much power to the laptop, it means it can deliver *up to* 85W. If you have a 40W Air, then that's the maximum that the charger will deliver. The only caveat is that the new Macs have the MagSafe2 connector, which may require you to get a MagSafe to MagSafe2 adapter.

The computer uses 19v 3.4 amps DC. The plug has a converter that inputs 100 to 240 volts AC and converts it to DC.

It does come with a power cord. It has no battery power.The way to use the usb port is to load it on a fob from your PC then transfer files to memory on photo frame

I have it plugged in to a MAC Powerbook. It is USB 2.0, I see no reason why it would not work.
