Product Info

Monoprice is known for offering quality accessories at competitive prices, and this extension cord is no exception. It sits in the entry-to-mid-range segment, providing a reliable alternative to more expensive branded cables. The product has been on the market for several years and remains widely available through Japan and other retailers. Warranty is typically one year (check with seller). No accessories are included – just the cable itself.

Best Use Cases

Home office or desk setup: The 15-foot length gives you plenty of slack to route cables neatly behind furniture or across a room. Ideal for desks located far from wall outlets. Server rack or UPS integration: Use this cord to connect rack-mounted equipment to a PDU or UPS. The 18AWG gauge supports up to 10A, sufficient for multiple monitors, a PC, and peripherals. Spare or replacement cable: Keep one on hand for temporary setups, LAN parties, or as a backup when an existing cord fails. Monoprice's build quality ensures it will last. Not for: Outdoor use, high-current appliances (space heaters, air conditioners), or direct connection to Japanese wall outlets without an adapter. Also not suitable for extension of other extension cords (daisy-chaining).
