Introduction
Lenovo recently launched the Legion Go S. Although it has received quite a bit of negative feedback regarding performance and battery life, it has still brought new energy to the handheld gaming market. Now, let’s take a closer look at its charging compatibility through a detailed visual analysis.
Charging Compatibility Test
Original Chargers
We first used the Lenovo 170W charger to charge the Legion Go S. The ChargerLAB POWER-Z KM003C tester recorded a charging power of 19.86V at 4.58A, totaling 90.94W.
When the test data is tabulated, we can see that Lenovo's own chargers all deliver a high voltage of 20V, with output currents ranging from 2.93A to 4.58A.
According to the bar chart, the highest power output came from the Lenovo 170W charger at 90.94W. The Lenovo 100W charger also performed well, providing 90.68W. Aside from the 100W chargers, the original 65W chargers delivered around 58–61W, demonstrating solid compatibility overall.
Third-party Chargers
After testing the official chargers, we moved on to evaluate how well the Legion Go S works with third-party chargers. Several models were selected for this round of testing, and the results are as follows:
Taking the HONOR 100W charger as an example, it was able to deliver 19.42V at 4.58A, reaching 90.28W.
Most third-party chargers were able to trigger the 20V charging voltage on the Lenovo Legion Go S, though a few only reached 12V. The current ranged from 0 to 4.6A.
When visualized in a bar chart, it’s clear that the Legion Go S’s charging power mostly clusters around three levels: 90W, 60W, and 25W. Overall, the device is compatible with high-output third-party chargers. However, we did observe that some chargers with output power between 18W and 30W had poor compatibility, resulting in unstable or failed charging. For the best charging experience, we recommend using chargers rated at 65W or higher.
Power Banks
Lastly, we tested power banks. Using the AOHi 27600mAh 240W power bank to charge the Legion Go S, we achieved a charging power of 19.37V, 4.58A, which is 88.67W.
The triggered voltage was mostly 20V, with a few cases of 12V, and the current ranged from 0 to 4.6A.
Again, visualized through a bar chart, we can see that charging power levels were concentrated around 90W, 60W, and 25W—quite similar to the third-party charger results.
Summary of ChargerLAB
In terms of charging compatibility, Lenovo's official chargers showed good overall performance. Most third-party chargers were able to trigger 20V, with a few only reaching 12V, and generally supported high power output. However, some chargers rated between 18W and 30W performed poorly and could not provide stable charging.
The power bank tests yielded similar results to third-party chargers, with most triggering 20V and a few at 12V.
Overall, the Legion Go S handheld gaming console tends to charge at three main power levels: 90W, 60W, and 25W. For an optimal charging experience, we recommend using chargers with an output of 65W or above.
