Review on Norstar DAVR-1500 1500W Step Up/Down Voltage Transformer and Automatic π Voltage Regulator Stabilizer β Convert 110/120V to 220/240V or 220/240V to 110/120V by John Thawngzauk
Poor performance, high idle boost
I compared LiteFuze and Norstar, at 1500W:1/4 load this unit was 89.6% efficient. Other brand 95.5%. The voltage at 1/4 load was 213 off, 120 volts on but the display kept showing 220. Terrible. The output voltage at full load dropped to 207 and the efficiency at 82.5% was significantly worse than the Litefuze. This device consumed 18 watts in standby mode, another brand 5 watts. I was disappointed and sent the device back. I would recommend buying a different brand.
- Great price
- Not the best
