Note:
1, AC input, AC output, output voltage is lower than(or equal to) input voltage; voltage can be adjusted only when connected to load; mainly used for resistive load(e.g. heating wire, incandescent light bulb).
2, It can not replace electric bicycles' battery charger, nor drive electric appliances which use switch power supply (such as 110V TV, speaker, refrigerator, air conditioner, rice cooker with a computer), and cannot drive induction cooker, energy saving lamp.
