4.1. Large Capacity & Pure Sine Wave Output

The R300 boasts a substantial 407Wh (110,000mAh) capacity. Its two AC outlets provide a pure sine wave output (rated 300W, peak 600W), delivering stable and clean power comparable to household electricity. This makes it safe for sensitive electronics like laptops and speakers. It can power an LED light (5W) for approximately 70 hours, a mobile phone (12W) for 30-35 charges, a Nintendo Switch (18W) for 15-20 charges, a laptop (50W) for 5-7 charges, a small drone for 5-7 charges, or a mini-refrigerator (40W) for 7-9 hours.
