Abstract
The present disclosure relates to a light string power supply, which includes a battery barrel with an open end and a detachable barrel cover. Inside are a circuit board, rechargeable battery, conducting plate, and metal spring. When assembled, the battery's anode connects to the circuit board's positive input terminal, while the cathode connects to the negative input terminal via the metal spring and conducting plate. The battery barrel's far end has a connection end with two holes for electrode plates, which connect to the circuit board's output terminals when inserted. The circuit board features a digital display for gear settings, enhancing usability. With no soldering points, the product offers longer lifespan and better consistency.
