Product Overview:
The CyberPower SL750U uninterruptible power supply (UPS) system provides surge protection for lightning-induced surges and other power events that can damage electronic equipment. This unit delivers enough battery backup to connected devices during a utility power failure, so you can perform a graceful shutdown to protect against the loss of data and damage to valuable electronics including computers, gaming consoles, and home networking equipment.

The SL750U has two Type A USB charging ports with 2.4A shared total output which gives you a faster charging time and can be used while on battery backup power. The slim profile allows for discrete installation and keyhole mounting slots allow for wall-mount applications as well.

Product Features:

• Battery Backup: Supplies power long enough for equipment to properly shut down when utility power fails. Helps prevent loss of data and minimizes the component stress caused by a hard shutdown.
• Surge Protection: Diverts excess voltage away from sensitive electronic equipment during an AC power surge or power spike to prevent damage.
• Simulated Sine Wave Output: Uses pulse wave modulation to generate a stepped, approximated sine wave to supply cost-effective battery backup power for equipment that does not require sine wave output.
• USB Charge Ports: Rapidly charge and power USB devices such as tablets (including iPad), smartphones, MP3 players, and other mobile accessories.
• GreenPower UPS™ High-Efficiency Design: Reduces power consumption by utilizing a compact charger and power inverter to create an ultra-efficient backup power system for home and office use.
• Widely Spaced Outlets: Accommodates large transformer-based plugs without compromising the access of other outlets.
• PowerPanel® Personal Software: Provides a user-friendly dashboard interface for controlling and monitoring the UPS.
• ENERGY STAR®: This model is an ENERGY STAR® qualified Uninterruptible Power Supply (UPS) system. ENERGY STAR is the trusted, government-backed symbol for energy-efficient products and practices that help save money and protect the environment.
• Connected Equipment Guarantee: CyberPower will repair or replace properly connected equipment if it is damaged by a power surge
