At.Q

At.Q (株式会社アットキュー) is a Japanese company that develops and sells consumer electronics accessories under the At.Q brand. Its product line, as shown on its official website, centers on USB Type-C charging and data cables — including ultra-fast PD60W and PD100W models, two-device simultaneous charging cables, reel cables, and right-angle adapters — alongside stereo earphones designed for clearer voice listening and small LED lamp bulbs. Product codes such as AT-PDCASTCC, AT-CASTUSCC, AT-CAREUSC, AT-PDADCC, AT-ES16, AT-EMS15, and AT-LDT01E12L indicate a structured in-house naming system. The company markets its cables as compatible with major devices, explicitly noting support for charging the Nintendo Switch 2 and Switch series, as well as iPhone 15/16 series charging via Type-C male-to-male cables. It also publishes compatibility caveats, such as not using its extension cable with eMarker-equipped cables above 60W and noting that Apple's iPad Pro bundled Type-C cable cannot be used with its extension cable. This level of compatibility guidance suggests a focus on practical, everyday charging and audio accessories for the Japanese market. At.Q communicates with customers through its official website and support email at the atq.co.jp domain. The site carries notices about summer holiday schedules, support center operating hours, and email spam-filter settings, indicating an active direct customer support operation. The brand appears to be a small-to-mid-sized Japanese accessories maker rather than a large multinational, with no public evidence in the supplied sources about its founding date, ownership structure, or listing status.

It provides detailed compatibility notes, such as confirming that its PD60W cables and extension cable support charging the Nintendo Switch 2 and Switch series, and that its Type-C male-to-male cables support iPhone 15/16 series charging. It also warns that its extension cable cannot be used with eMarker-equipped cables above 60W and that Apple's iPad Pro bundled Type-C cable cannot be used with its extension cable.
