Negative Positive
Title: Did not perform to expectations; returned after one use
Review: Bought the unit to run 4 strings of christmas lights that adorned an outdoor craft fair booth. Lights drew 400 watts (seemed OK as unit was advertised as having a 600 watt inverter), however, unit only lasted 3 minutes before the internal alarm sounded -- even after recommended 35-hour first charge. Even using only one string of lights (100 watts), the battery only lasted approximately 10 minutes before the alarm sounded. Too bad - this seemed like such a good idea for quiet, long lasting outdoor power.
