ADATA XPG has showcased a selection of new products at Computex 2026, but one that caught my eye was a keyboard that lacks traditional lithium batteries commonly found in wireless keyboards. However, this new wireless keyboard can last months on a single charge.

But how, you ask? One answer. Instead of a lithium-ion battery, XPG has opted for a supercapacitor, which stores energy differently. For example, a supercapacitor stores energy as an electric field on charged surfaces, or electrostatically, whereas a traditional lithium battery stores energy chemically.
The advantages of supercapacitors are that they can charge to full within seconds/minutes, have no risk of thermal runaway, but hold far less total charge capacity.

However, in the context of the new XPG keyboard or any other supercapacitor keyboard, the keyboards are designed to slowly sip power from the source, enabling a single charge to last for months.
XPG informed me this is their first supercapacitor keyboard and that it's not aimed at gamers, but rather at professionals who need a portable keyboard that stays charged and charges quickly when they are in a tight spot. However, that doesn't mean the keyboard can't be used for games if the user chooses.
Additionally, since the keyboard uses a supercapacitor rather than a lithium-ion battery, XPG doesn't have to worry about international shipping restrictions for lithium-ion batteries. XPG didn't give me a release date for a keyboard or a price, but I will be sure to update you if either piece of information comes across my desk.
