Your modem just dropped mid-meeting. Again. The APC Back-UPS Pro 650VA/400W keeps your PC, router, and external drives running through the next brownout without you touching a thing. Four outlets give you full battery backup plus surge protection; two more handle surge only. Automatic Voltage Regulation smooths out the voltage wobble before it ever reaches your gear — no battery drain for a 5% dip. The LCD shows load, battery level, and status so you're never guessing. USB-C ports keep your phone charged while you wait out the outage. Lead-acid battery recharges in 8 hours. Line-interactive topology with stepped-approximation sine wave output and an 8ms transfer time. Tower form sits on or under your desk: 190 mm tall, 91 mm wide, 310 mm deep, 6.4 kg. CE certified. 24-month warranty on the unit, 12 months on the battery
