不兼容读卡器与充电盒要分别确认
表格确认 X5 / X4 Air Quick Reader 可用于 X5，并明确不支持具名的 X4、X3 读卡器。这个结论只针对这些读卡器，不是所有 USB-C 配件的统一判断。
充电方面，X5 Utility Fast Charge Case 被列为支持；X4 Air Utility Fast Charge Case 与 X4 Fast Charge Hub 则不支持 X5。读卡器可以共享，不代表充电配件也通用。
留意明确例外，不只看代际名称
X5/X4 Lens Cap 被明确列为支持，X3 Lens Cap 则不支持；X5 Water Sports Rope Mount 也支持 X5。正是这些具名例外，使“旧配件全通用”或“全部不能沿用”都不准确。
下方矩阵保留不支持与已确认配对。没有列出的项目在这里属于未确认，而不是自动不兼容。适配结论也不等于确认资料未写明的潜水深度、承重或活动安全性。
