We recommend measuring up the distance between your outlet and where you intend to charge your device, think about your usage and scenes, and order the right length.
• 6.6ft：Flexible placements in any setting. Most people use it to charge phones at night beside the bed or take with travel.
• 10ft：Extended freedom across the room. Most people pick up 10ft cables cos it offers a length ready for every situation.
• 15ft：Enough length for charging indoor or outdoor. Most people buy 15ft cable to use in the office to charge laptops.
