Expect roughly 3-5 minutes at half load. Users report up to 15-20 minutes for very light loads like a router and single monitor.
Includes a "Green Mode" for energy saving during low-load conditions. User Feedback & Long-term Reliability bnt 400a схема
When running on battery, it produces an approximated sine wave (stepped square wave). This is fine for most PC power supplies but may cause buzzing in high-end audio equipment or motors. Technical Performance Expect roughly 3-5 minutes at half load
It can boost or buck incoming voltage without switching to battery power, which extends battery life in areas with unstable grids. bnt 400a схема
