Now, a new Nokia smartphone with the model number TA-1399 was certified by China Quality Certification Center (CQC) on September 7. The input ratings for the device are 5 V at 3 A (15 W) and 9 V at 2 A (18 W), which means that Nokia Mobile could be shipping it with an 18 W power adapter.
With that, the known model numbers of the upcoming devices are as follows:
The support for 18 W charging places the Nokia TA-1399 above the Nokia G50 and Nokia T20 since the other two support only 10 W charging. And Nokia G300 and Nokia X100 are the only other two known Nokia devices among the upcoming ones, so TA-1399 might very well be a variant of one of them unless Nokia Mobile has another smartphone on the way, which it has managed to keep under the wraps.
