Specification The fastest voltage can reach about 180 V Vintage hand generator Send stainless steel extended foldable handle Total weight is only 1 kg Portable and lightweight Voltage is guaranteed to be above 110 V AC under no-load conditions. The faster the shock, the higher the voltage. (Generally at 130 V - 150 V), it can light 220 V 25 W incandescent lamps and 220 V 30 W energy saving lamps. Feature 1st motor retrofitted from a brand new bearing motor (large gear plate made of aluminium, pinion made of steel) from early decades of 65-1 magnet phones. Equipped with an extended stainless steel handle, hand cranking is easier. 2. to see the tension more intuitively, we have added a tension gauge to make it easier to see the tension. 3. the silver-plated push type connector pin is used, which is more convenient for wiring as long as you push it down from the top and the wire is pinched. 4. This generator can be used for small experiments, DIY production, etc. Package include: 1*hand crank generator
