    I have 5 300 VA units, 2x cheap brand, 2x CyberPower, 1x Eaton.
    I think 2 of them don’t have a transformer.

    Does it matter? All have a 9 Ah 12 V battery.
    It will last few to 20 minutes maybe.
    No issues so far (battery capacity loss excluded).

    Recently, as someone recommends, all batteries are outside of UPS enclosure,
    lower temperature. Which could affect battery lifetime.

    More power, more money 👀









  • If you surprised why it has a PowerPC CPU. It’s actually a SoC.
    From the manual:

    AMCC PowerPC 405 32-bit RISC processor core operating up to 333MHz with 16KB D-and I-caches.

    Designed specifically to address embedded applications, the PowerPC 405EP (PPC405EP), provides a high-performance, low-power solution that interfaces to a wide range of peripherals by incorporating on-chip power management features and lower power dissipation requirements.
