How to change 3v to 2v?
I want to install some LED string lights in my garden. The package comes with a solar charger (2V 100mA), built in battery (600mAh) and 30 meters of wire and 300 LED bulbs. The problem is that I cannot use the solar charger this time of year. So I want to cut the wires and join them to a power supply.
The lowest voltage adapter i can find is 3V. Do I need to change the 3V to 2V? How?
