Designed for a wide range of batterypowered devices, including clocks, alarm clocks, digital scales, remote controls, toys, and LED lights. Compatible with power sources such as mobile power banks, computers, and standard USB adapters. Not suitable for use with regular 1.5V batteries. Offers a costeffective alternative to disposable LR03 batteries by reducing the need for frequent replacements. Includes a green dummy battery (0V) that functions as a conductor to complete the circuit where required. Ideal for applications where devices require continuous lowvoltage power without the inconvenience of replacing standard batteries. Practical usage scenarios: 1. Keep a wall clock running reliably without the hassle of changing batteries every few months. 2. Power an LED desk light from a USB port for steady, uninterrupted operation. 3. Use with a kitchen scale to ensure accurate measurements without worry about battery depletion. Key benefits: Saves time and money by eliminating the recurring cost of disposable batteries. Reduces electronic waste for a more ecoconscious power solution. Simple to use with plugandplay compatibility for many everyday electronic devices.
