Mercury Maverick 850 UPS Offline 850VA/510W
The Mercury Maverick 850 is a compact offline UPS built to keep a PC, router, or small home appliance running through a brief power cut. Rated at 850VA/510W, it switches to battery power within 2–6ms (max 10ms), giving connected devices enough time to save work before a full shutdown. Boost and buck AVR corrects minor voltage fluctuations directly from mains power without switching to the battery, which helps extend battery life over time. The unit ships with a 12V/9AH battery, delivers a simulated sine wave in battery mode, and offers typical backup of 15–25 minutes depending on the connected load — enough to ride out short outages on workstations, routers, TVs, or small CCTV systems.
