      \ud83d\udd0b Autonomy & performance<\/h2>\n

      Inverter autonomy is highly dependent on the connected load:<\/p>\n

        \n
      • \ud83d\udfe5 F ull charge (500 W)<\/strong>: ~2minutes<\/strong> – enough to back-up and switch off your devices cleanly when the power is off.<\/li>\n
      • \ud83d\udfe8 Medium load (~250 W)<\/strong>: ~6-8minutes<\/strong> – ideal for router, modem, thin PC or NAS for safe shutdown.<\/li>\n
      • \ud83d\udfe9 Reduced load (~100 W)<\/strong>: ~15-30minutes<\/strong> – may be enough to keep your network active or complete a task before complete shutdown.
        (Note: These times are estimates based on typical specifications and tests for UPS of this type).<\/li>\n<\/ul>\n

        \ud83d\udc49 F ull battery recharge:<\/strong> ~8 hours
        \ud83d\udc49 Battery type:<\/strong> Sealed lead-acid (not user-replaceable)
        \ud83d\udc49 Transfer time:<\/strong> ~8 ms (very fast to avoid visible interruptions)<\/p>\n
