We did an exclusive hands-on of the world's first 2C1A multiport GaN charger - the Baseus 65W 2C1A multiport GaN charger, few weeks ago, which was unveiled at a special event in Shenzhen, China, on August 18. The charger has foldable prongs and an LED indicator on the side. It will be available in mainland China starting in early September.
It is based on GaNFast solution from Navitas which enables high wattage inside an ultra compact form factor. It also makes the first debut of GaNFast on a multiport charger (the RAVPower 45W Ultrathin and AUKEY 27W PA-Y19 are single port chargers based on GaNFast). GaN, or Gallium Nitride, which is a new type of semiconductor material that offers higher efficiency, higher thermal conductivity, higher temperature resistance, and other advantages than traditional silicon. When it comes to charging, GaN can greatly reduce the size and boost the efficiency of a charger.
Here's our teardown review of the Baseus 65W 2C1A multiport GaN charger.

It weights 124.8g/4.4oz.
![Baseus 65W 2C1A Multiport GaN Charger Teardown Review-Chargerlab](http://www.chargerlab.com/wp-content/uploads/2019/10/180947uz6675ktbff8r7u7-1024x683.jpeg)
Using the ChargerLAB POWER-Z KT001, we can see its USB-A port covers a wide range of charging protocols including Apple 2.4A, DCP, QC 2.0, QC 3.0, AFC, FCP, and SCP.
![Baseus 65W 2C1A Multiport GaN Charger Teardown Review-Chargerlab](http://www.chargerlab.com/wp-content/uploads/2019/10/180948wutueedml7umt4hh-1024x683.jpeg)
So does the USB-C1 port.
![Baseus 65W 2C1A Multiport GaN Charger Teardown Review-Chargerlab](http://www.chargerlab.com/wp-content/uploads/2019/10/180948mtoyoy9aooaaatao-1-1024x683.jpeg)
The USB-C1 port also supports USB PD 3.0 PPS with 5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/3A PDO steps and a 3.3V-21V/3A PPS step.
According to Akavo, in order to prevent some of the cable problems, the USB-C1 port turns off the 65W maximum output by default (which means 60W max for USB-C1 by default). The way to enable 65W output is to plug and unplug the USB-C2, then you can use a 5A E-Marked cable to pull the full 65W from the USB-C1 port.
![Baseus 65W 2C1A Multiport GaN Charger Teardown Review-Chargerlab](http://www.chargerlab.com/wp-content/uploads/2019/10/180949uuucccyy7m7iuy7z-1024x683.jpeg)
The USB-C2 port also supports Apple 2.4A, DCP, QC 2.0, QC 3.0, AFC, FCP, and SCP.
![Baseus 65W 2C1A Multiport GaN Charger Teardown Review-Chargerlab](http://www.chargerlab.com/wp-content/uploads/2019/10/180949hi0bagzsisagwraz-1024x683.jpeg)
The USB-C2 port also supports USB PD 3.0 PPS with 5V/3A, 9V/3A, 12V/2.5A, 15V/2A, 20V/1.5A PDO steps and 3.3V-11V/3A, 3.3V-16V/2A PPS steps.
![Baseus 65W 2C1A Multiport GaN Charger Teardown Review-Chargerlab](http://www.chargerlab.com/wp-content/uploads/2019/10/180950fxc3w113mw1n3qe2-1024x683.jpeg)
When both of the two USB-C ports are used:
USB-C1 output will change to: 5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/2.25A and 3.3V-16V/3A (PPS)
USB-C2 output will change to: 5V/3A, 9V/2A, 12V/1.5A, and 3.3V-5.9V/3A (PPS), 3.3V-11V/2A (PPS)
![Baseus 65W 2C1A Multiport GaN Charger Teardown Review-Chargerlab](http://www.chargerlab.com/wp-content/uploads/2019/10/180950tu0z8jy0n8wh6w6b-1024x683.jpeg)
When all the ports are used, the USB-C2 and USB-A will be locked to 5V, while the USB-C1 can still output 45W max PDO, or 48W PPS.

What about charging speed of Samsung Galaxy Note 10/10+ with this modern charger compared with default Samsung 25w charger?
@Ivan Abramenko: According to chargerlab - "3.3V-11V/3A, 3.3V-16V/2A PPS steps" - it supports 2A only when using 15V. SGalaxy Note 10+ seem to use 15V/3A (and PPS) for the fast 45W-charging.
"The way to enable 65W output is to plug and unplug the USB-C2, then you can use a 5A E-Marked cable to pull the full 65W from the USB-C1 port."
This is a weird way to enable its full potential ^^" It's a good thing to prevent clueless users damaging their non-e-marked usb-c cables, on the other hand it's a bit bothersome to do that all the time. Did you guys check it, if the 65W are fully available after doing the trick?
After reading this, I'm questioning myself why I should get myself a e-marked USB-C cable that is 20V/5A (100W) compatible. A USB C-cable supporting 20V/3A (60W) only will be sufficient enough when using this charger.
@asdfwww: Yes. That's a one-time trick.
