Trên tay cục sạc xe hơi USB-C của Belkin, 27W, sạc được cho laptop

@TsanHoang Vãi cả đoán. Thay vì dùng đồng hồ đo. Họ dùng usb đo nguồn rõ ràng ràng ra đó lại đi kêu đoán. Bạn nên tìm hiểu lại công nghệ sạc pin hiện tại rồi hãy bình luận.

YOUR SETTINGS ARE IMPORTANT
You will also want to watch your USB-C power mode, which you can find in your laptop settings, usually in the power/battery section. Here, you may find that you can switch Type-C’s output, choosing whether to receive power or send power. If your USB-C laptop charger isn’t working when by all rights it should be, check your settings to make sure it is set to receive power.

COMPLEX CHARGING ARRANGEMENTS

Because USB-C is universal and can do multiple things at once, this allows for some unique charging circumstances. Two worth nothing are:

Charge-through: Let’s say you have a portable screen for presentations, and a laptop, both with USB-C connections that include the ability to send or receive power. Sure, you could just use that connection to send your presentation to the screen. But with the right setup, you can also use that connection to charge your laptop battery. The screen gets its power from a traditional outlet, and sends a charge out to your laptop. That means your laptop would never run out of juice in the middle of a presentation.

Portable chargers: Maybe you have a portable charger with an old USB connection, but a phone that only has a USB-C connection (which is not compatible with older USB ports). You can link the charger to a laptop that has both types of ports, and use it to power up your phone in a roundabout way. The reverse is also true, if you have a portable charger that only works with USB-C connections. It’s important to keep an eye on your settings in these laptop-to-phone connections, but with the right arrangement, many exchanges are possible. It’s not the most efficient method of charging, but it does work in an emergency. Do not try to use your laptop Type C charger to charge your phone directly. The voltage requirements are too different, and multi-device chargers are still a nascent part of the market.
