Surface Go Tip: Can you charge Surface Go with a standard USB charger?

In this article, we will test and study the Surface Go charging speed using a typical USB charger with USB-A to USB-C cable.

Surface Go Standard USB Charger

In our previous article, we’ve benchmarked the Surface Go charging speed using the original charger, which uses the Surface Connect port. But Surface Go has another option that allows you to charge via USB-C port. Generally, charging over USB-C on a modern portable computer required a charger and cable that supports USB Power Delivery or USB-PD technology to deliver more power throughput for fast charging.

However, in a situation that you don’t have a USB-PD charger or you didn’t take it while on the go, can you use a standard USB charger to charge your Surface Go instead? In this article, we will benchmark the Surface Go charging speed using a standard USB charger.

Standard USB Charger Specification

In this test, we chose the original charger for the Sony Xperia XA which is included in the phone box. It’s a simple charger with only 1500mA power output and has no Quick Charge or Power Delivery support at all.

Standard USB Charging Speed on Surface Go

What we can see from the testing, the charger can charge Surface Go not only while it’s off but also in use. But it takes quite a long time (about 6 hours) to charge Surface Go from 20% to 100% in our test scenario.

The following table summarizes the speed, duration, and charging rate of the charger.

Note The following results are measured using a certain condition which is specified in the Experiment Condition section of this article.

Battery Capacity (%)Average Charging Rate (W)Duration (Minutes)
20% - 80%3.68 W265 Minutes
80% - 90%3.50 W47 Minutes
90% - 95%3.42 W23 Minutes
95% - 100%3.18 W25 Minutes
20% - 100%3.68 W - 3.18 W6 Hours or 360 Minutes

And below is a graph detailing the charging behavior using standard USB charger over USB-A to USB-C port:

For a quick comparison, below is the graph of Surface Go charging speed using the original charger over Surface Connect port.

Experiment Condition

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 software.

Below is a 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)

Recording Tools

Charging Speed Testing Tools

The tool we used to record the battery capacity, speed and duration of the charging is BatteryInfoView. Beside that, this tool also has the ability to display more detail information of 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:

Since Surface Go is compatible with both the Surface Connect and the USB-C charging interface, you have many options when you want additional chargers to be used while on the go, at home, or at the office.
