WhatCable: Know what your USB-C cable can do

摘要

WhatCable 是一个帮助用户了解 USB - C 线缆能力的工具。它通过展示充电器能提供多少功率、线缆支持什么规格,以及设备(如 Mac)实际吸取的功率,来解释充电慢的原因,而不是让用户盲目更换配件。示例中显示充电器和线缆正常,Mac 在需要时最高可吸取 94W 功率。

荐读理由

做硬件或充电相关产品时,可直接借鉴它把充电器、线缆、设备三端功率数据可视化并给出结论的思路,省去用户盲换配件排查的功夫

原文

Why is this Mac charging slowly?

See what the charger offers, what the cable supports, and whether the Mac is drawing all the power it needs. WhatCable explains the result instead of leaving you to swap components at random.

Charger and cable are fine. The Mac will draw up to 94W when it needs to.
