One of the key features of Surface Go is about getting the job done on the go. It is the most portable Surface PC that packs a ton of capabilities and features as its big brothers. However, one thing that most people don’t happy about is battery life. The Surface Go definitely won’t last for a typical working day unless you did all our ultimate battery-saving tips as mentioned in our article.
At SurfaceTip, we have done two tests already for the Surface Go charging topic, the original charger testing, and a basic phone charger testing. However, we didn’t test another potential charging method using USB-C with power delivery yet. Today, we will test, not one but three, different types of USB-C PD chargers to find out how fast they can charge the Microsoft Surface Go compared to our previous tests.
- Can you charge the Surface Go with USB-C?
- How to charge Surface Go with USB-C?
- Surface Go USB-C chargers we’ve tested
- Surface Go USB-C chargers testing result
- What we’ve learned from the result
- Experiment Condition
In short, yes you can. The USB-C 3.1 Gen 1 port on Microsoft Surface Go does support smart charging along with data transfer and video out capability. It supports USB Power Delivery revision 3.0 which supports 4 different power rules (5v, 9v, 15v, and 20v) with the ability to supply power up to over 45W.
With that said, you will need a compatible USB-C with Power Delivery which is rated at a higher wattage to fast charge your Surface Go. Fortunately, as we tested, the Surface Go can also be slowly charged via a standard USB charger as well. So, if you can’t find a USB-C PD charger, don’t panic, you can use any phone’s USB charger or power bank to continue your work.
It’s really simple to charge your Surface with USB-C. Just like the Surface Connect connector, the USB-C connector itself is reversible, so you don’t have to worry about the wrong side plug-in. Anyway, there 2 ways to charge your Surface Go over USB-C depending on the available charger port:
- USB-A to USB-C: You can charge your Surface Go with any standard USB charger or portable power bank with a good charging rate (at least 5V/1.5A) by connecting them with the USB-A to USB-C cable.
- USB-C to USB-C: If you have a USB-C PD charger, which is highly recommended, and they are using a USB-C port, then you can charge your Surface Go by connecting them with the USB-C to USB-C cable.
To find out what type of USB-C PD chargers work best for Microsoft Surface Go, we have tested three different chargers with USB-C PD support. To help you understand more about each charger’s specifications, we have put them together in the table below:
|USB-C PD Chargers||Interface||Max Wattage||Power Rules|
|Google Pixel 2 charger||USB-C to USB-C||18W||
|Anker PowerPort Speed PD 30||USB-C to USB-C||30W||
5V/3A 9V/3A 15V/2A 20V/1.5A
|ZMI Turbo USB-C PD||USB-C to USB-C||45W||
5V/3A 9V/3A 12V/3A 15V/3A 20V/2.25A
For better comparison, below is the specification of the original Surface Go charger and a standard phone charger that we’ve already tested:
|Common Chargers||Interface||Max Wattage||Power Rules|
|Sony Standard Phone Charger||USB-A to USB-C||7.5W||
|Surface Go Charger||Surface Connect||24W||
Now we have an array of chargers with a power range from 7.5W up to 45W with different types of charging interfaces. And now it’s time to test it out, read on for the actual charging speed of those chargers.
The following table summarizes the speed, duration, and charging rate of each charger. We have ordered the chargers at the maximum charging rate they can offer.
|Sony Standard Phone Charger|
|4.0W - 3.6W|
|3.59 - 3.43W|
|3.42W - 2.37W|
|4.0W - 2.37W
5 hours 57 Minutes
|Google Pixel 2 charger|
|11.2W - 10.2W|
|10W - 8W|
|7.8W - 2.5W|
|11.2W - 2.5W
2 hours 17 Minutes
|Surface Go Charger|
|16.6W - 14.5W|
|14W - 8.2W|
|8W - 2.1W|
|16.6W - 2.1W
1 hour 48 Minutes
|Anker PowerPort Speed PD 30|
|18.0W - 16.4W|
|13W - 9W|
|8W - 2.6W|
|17.3W - 2.6W
1 hour 39 Minutes
|ZMI Turbo USB-C PD|
|26.3W - 14.9W|
|13W - 7W|
|7W - 2W|
|26.3W - 2W
1 hour 39 Minutes
Now we’ve seen the result. Here are some facts that we can see:
- Battery below 80%: you can expect to get the peak charging rate of each charger.
- Battery between 80% – 90%: the charging rate starts to slow down to around 8W.
- Battery between 90% – 99%: the charging rate drop dramatically down to around 2.5W which takes twice as long as between 80%-90%.
- Battery between 99% – 100%: Our tested Surface Go took about 25 minutes to fully charge from 99% no matter what chargers we’ve tried.
Of course, the actual charging speed depends on your device’s settings and usage. It will be much faster to charge your device when it’s off, and it will be slow as you play games or use any heavy tasks.
Below is the testing condition that we used and think most people would use in the general situation:
- Turn off the display: Never (Always-on display)
- Display brightness: 50%
- Auto brightness: No
- Bluetooth: On
- WiFi: On (connected to the internet)
The tool we used to track the battery capacity, speed, and duration of the charging is BatteryInfoView. Besides that, this tool also can display more detailed information about your device’s battery.
We also use our favorite tool BatteryBar to view real-time charging stats right from the taskbar. You can download both tools for free from the links below:
