AYANEO Kun Battery Is 4 Times Larger Than the Steam Deck’s

AYANEO’s next big Windows handheld, the AYANEO Kun, houses a battery with a capacity of around four times larger than that of the Steam Deck and ASUS ROG Ally.

Driving the news: According to AYANEO, the Kun handheld comes equipped with a 75Wh (19500mAh) battery. To put this size in perspective, the battery inside both the Steam Deck and ASUS ROG Ally comes in at around 40Wh (5000mAh). 

In a rough comparison, that means the AYANEO Kun has almost double the watt hours (Wh) and just under four times the Milliampere hours (mAh).

Running the numbers: While no calculation is accurate, we can get a rough ballpark of how this extra larger 75Wh battery will work in practice. 

  • At 30 watts, the AYANEO Kun should last two hours and 30 minutes.
  • At 15 watts, the AYANEO Kun should last five hours.
  • At 10 watts, the AYANEO Kun should last seven hours and 30 minutes.

For comparison:

  • At 30 watts, the Steam Deck and ASUS ROG Ally last around one hour and 18 minutes.
  • At 15 watts, the Steam Deck and ASUS ROG Ally last around two hours and 36 minutes.
  • At 10 watts, the Steam Deck and ASUS ROG Ally last around four hours.

Why it matters: One of the biggest problems with high-end handhelds is the lack of battery life. Playing a modern AAA like Cyberpunk 2077 yields a higher power consumption than running an indie game like The Binding of Isaac. 

Then when you factor in the operating system – normally eyes fall on Linux or Windows – and most users will spend most of their time gaming while connected to a power supply. 

This is less of an issue when playing in docked mode as the handheld is constantly attached to a plug socket. But if you wanted to use the device for a long commute, chances are the battery won’t last. 

By including a 75Wh battery AYANEO stands as the first company to potentially solve this ongoing problem. Of course, how the Windows operating system will factor in isn’t yet known. But on paper, the math checks out.

Further Reading: The AYANEO Kun was first teased in early July and is being dubbed the company’s most powerful handheld.

The device features an 8.4-inch screen and comes equipped with the AMD 7840U CPU. A similar CPU resides in that of the ASUS ROG Ally, although the Ally’s version doesn’t include modified drivers from AMD yet, meaning the AYANEO Kun should be able to beat it outright in terms of power. 

  • Screen size: 8.4-inch IPS true color screen.
  • CPU: AMD 7840U. 
  • Battery size: 75Wh (19500mAh)
  • Controls: Includes touchpads and rear buttons.
  • Misc: Floating eight-way directional pad, hall sensing joystick and triggers.
  • Operating system: Windows 11 with AYASpace 2.
