Softbank's 2018 27W USB Certified Power Delivery based USB-C Charger is No Different Than the First
The 27W Softbank SELECTION USB PD Enabled USB Type-C Fast Charging AC Adapter was released by SoftBank Commerce & Service in 2017 as its first USB Power Delivery 2.0 enabled USB Type-C charger for phones. This was then followed up with the 2018 Softbank SELECTION USB PD USB Type-C Rapid Charging AC Adapter by the Japan mobile giant as a newer version of the 2017 charger.
The Softbank SELECTION USB PD USB Type-C Rapid Charging AC Adapter (2018) isn't an entirely new charger but more like a clone of the previous version. The 2018 charger offers pretty much the same specs and capabilities as well as a almost identical design.
The Softbank SELECTION USB PD USB Type-C Rapid Charging AC Adapter (2018) also advertises the USB certification logo on both the charger and box, proudly claiming that it has been certified by the USB Implementers Forum. Notice the Softbank owned Y!mobile brand now gets printed on the charger's box which previously was missing.
Similarly, the 2018 charger also includes a number of safety features such as being able to detect if the temperature gets abnormally hot due to some foreign material around the connector. By automatically shutting down the power supply upon detection of irregular temperature rise, the charger can help prevent fires and meltdowns from accidentally occurring.
The Softbank SELECTION USB PD USB Type-C Rapid Charging AC Adapter (2018) also comes with a 1.5 meter tethered cable so you don't need to buy a separate USB cable. When not in use, you can also fold the AC plug into the charger's body to make the adapter more portable and less likely to scratch other items.
The Softbank SELECTION USB PD USB Type-C Rapid Charging AC Adapter (2018) still supports max 27W output using the same charging profiles of 15 watts (5 volts @ 3 amps), 21 watts (7 volts @ 3 amps), 27 watts (9 volts @ 3 amps), and 27 watts (12 volts @ 2.25 amps) as the earlier model.
We'll be testing this charger to see how it works with various USB devices in upcoming reviews.
