Product Overview Buffalo Portable Blu-ray Drive BRXL-PTV6U3-WHB White Features Equipped with "Notification LED" + "Boost Cable" Features a "Notification LED" that clearly indicates power shortages when connected to a computer with insufficient power supply. If the notification LED turns red, you can supplement the power shortage by using the "Boost Cable" (USB connection). * Can be used with computers that have two USB ports. If you have only one USB port, please prepare a separate self-powered USB hub. * If the ports are far apart, please prepare a separate extension cable. * If it still doesn't work even with the Boost Cable, please use our optional adapter "AC-DC5 series". Slim Body to Match Thin Computers Slim design with a thickness of 14.4mm to match thin computers. It's also lightweight at approximately 300g, making it easy to carry around. W-cable storage for comfortable use and portability. While I can't offer a significant price reduction, I can offer a small discount. Please feel free to contact me. I will pack it properly and ship it. Thank you for looking.
