The Back-UPS BE850M2 Power Supply from APC is a combination of a battery backup and surge protector to offer protection and power for your connected electronic equipment. This power supply sports a total of nine power outlets, and six of these outlets provide power in the event of a power outage. It comes built with a hot-swappable battery that powers an entry-level computer up to 90 minutes or lets you safely power down a mid-range computer system connected to multiple support devices.
For convenience, it comes with three transformer-sized outlets as well as two USB ports, which allow you to charge mobile devices without using USB wall adapters. There are also audio alarms and LED indicators to notify you of replacing the onboard battery or damaged wiring inside a building.
