Review on 💨 Rev Up Your Power Supply with the Topoox 1730RPM Electric Turbine Generator by Alfonso Tipton

Tested immediately upon delivery and found none of the 6 to work at the stated voltage: Rated: 3VDC; Rated speed: 1730 rpm; Operating voltage: 1.5-9VDC current. The motors were wired in series using a standard battery holder with fresh 1.5V batteries. All cable and battery connections were solid and reliable. Motors will NOT operate at 1.5V, 3V, or 9V, the specified operating voltage range. However, at 3V and 9V, the shaft tried to rotate, but failed to do so even with help. Given the positive reviews of previous buyers for this engine, this must have been a bad batch. All 6 were returned for a refund.
