It is at a stage where diffusion is progressed as the next generation USB interfaceUSB Type-CIn addition to the merit of being able to insert the connector on either side, the standard supports the ability to supply enough power to drive the notebook PC. In terms of theory, if you have the same USB Type-C port, you should be able to charge the notebook PC even if the maker is different, so whether PCWorld can really charge major notebook PCs We are carrying out the test.

For this test PCWorld prepared laptops sold by Acer, Apple, Asus, Dell, HP, Lenovo. Each has a USB Type-C terminal, which is a model that can charge the battery and supply power to the main unit with the USB Type-C cable. In the market, models from these manufacturers are chosen as they account for 80% of the total market share. In addition, we prepared Google Chromebook Pixel for reference and Nexus 6P made by Huawei to verify that it can also be used on smartphones.


Actually, when PCWorld conducted a similar test in 2016, there were cases in which it could not be charged properly. The table below summarizes the results, the charger in the column and the notebook PC in the row are lining up side by side, but the surprise that HP Specter X 2 can not charge at all if it is a charger other than our own To the results of. Other cases that can not be charged satisfactorily are successive, and USB Type-C, which purports to be "universal connection", was left with a result which can only be regrettable with this possession.


A year after such a result, it was this test that was carried out as a re-partitioning. Each manufacturer's charger is connected to the power strip, and the compatibility between the charger and the notebook PC / smartphone is checked without fail in the brute-force match by manufacturer. In addition, as a representative mobile batteryInnergie PowerGear USB-C 45 45 W Laptop AdapterAre prepared for you.


In checking, you can measure the voltage and current by simply inserting it in the USB portSatechi USB-C power meter testerUse numerical value confirmation.


And the results of the test are shown in the table below. It can be determined at first glance that the number of red cells is decreasing than the result one year ago, and it makes me feel that the performance of universal power supply is real. The only obstacle seems to be that the charger for Lenovo Yoga 910 could not charge the Apple MacBook Pro 13, HP Specter x 360 13 t, Asus Zenbook 3. Lenovo Yoga 910 itself is working safely with any manufacturer's charger, so it is believed that the cause is on the charger side. Also, the yellow cell indicates that it often means that the case where HP Specter x 360 13 t charger was connected to Apple MacBook Pro 13 was often not recognized well.


From this result, it seems to be said that the fact that universal power supply by USB Type-C has become a reality is finally becoming highlighted.
