The primary signal is desiredSize on the controller. It can be positive (wants data), zero (at capacity), negative (over capacity), or null (closed). Producers are supposed to check this value and stop enqueueing when it's not positive. But there's nothing enforcing this: controller.enqueue() always succeeds, even when desiredSize is deeply negative.
Aside from keeping devices powered up efficiently, the GoCable includes hidden tools for extra convenience. You’ll have quick access to a bottle opener and a hidden cutter for opening packages safely. The included carabiner clip lets you attach this to bags or belts in seconds, so you can always keep it within arm’s reach.，更多细节参见旺商聊官方下载
