Arcade game machines require reliable backup power to prevent data loss, hardware damage, and gameplay interruptions during outages. The most common solutions include uninterruptible power supply (UPS) systems, which provide immediate battery power for short durations; generators, offering long-term electricity through fuel sources like gasoline or propane; and power inverters paired with batteries, converting DC power to AC for flexible use. UPS systems are ideal for safeguarding high scores and settings, while generators suit extended outages in commercial settings. Power inverters offer portability for home arcades. Factors like cost, runtime, and maintenance should guide your choice to ensure continuous fun and protection for your arcade investments.
