At the launch conference of iPhone SE and 9.7-inch iPad Pro, Apple also released an additional USB Type-C to Lightning interface data cable. With this cable, you can use the dual head Type-C charger of New Macbook to charge the iPad Pro. In addition, Apple also sold the 29W Type-C interface charger independently.

Comparison between 29W charging head and original 12W charging head

This is definitely a good news for iPad series with charging time more than 4 hours, but what is the final charging speed? The foreign media 9to5Mac used a 29W charging head and an original charging head for charging test.

The 12.9 inch iPad Pro starts charging from 0% of the power. During the process, it turns on and keeps the highest brightness constantly on. As a result, the 29W charging head charges 6% in 10 minutes, then the screen brightness is adjusted to the lowest, 11% in 15 minutes, and 14% in 20 minutes. and In the same environment, the original charger charges 2% in 10 minutes, the brightness is adjusted to the minimum, the charge is 4% in 15 minutes, and the charge is 5% in 20 minutes. The 20 minute charging speed has really increased by 140%. If you can keep this speed, it will be fully charged in less than 2.5 hours.

Everyone has to sigh that this is the charging speed that iPad Pro should have. However, the bad news is behind us. The 1-meter and 2-meter versions of the adapter cable are priced at 188 yuan and 258 yuan, while the 29W Type-C interface charger Shenghui is 388 yuan... As a high-end tablet with a starting price of 5888 yuan, it is a sad story to buy an additional 576 yuan of accessories to fully charge.
