The 1500VA model offers 900W power capacity with 10 outlets - 6 battery backup outlets to keep equipment running during outages, and 4 surge-only outlets. It features automatic voltage regulation to correct unsafe voltage fluctuations, sine wave output ideal for sensitive electronics, a replaceable battery, and USB-C plus USB-A charging ports. The 900VA model provides 540W capacity with 8 outlets - 6 battery backup outlets and 2 surge-only outlets. It adds a USB-C port and USB-A port for device charging during an outage.
