power bank with a built-in solar panel. The power stored in the internal battery or direct sunlight allows you to charge your phone anywhere, anytime. A power bank with a solar panel is a mobile power source. An inductive charger is required to charge your device. No cables are required. Electronic charging protection systems are included. With the Solar Charger, you can charge electronic devices almost anywhere. The inductive charger allows you to charge your device without connecting it with a cable. Simply place your device on the charger to automatically begin charging. The power bank has a built-in solar panel; you don't need access to the mains to charge it. The power bank is powered by a high-performance lithium-polymer battery. It is smaller, longer-lasting, and lighter than standard batteries. It uses state-of-the-art PD (Power Delivery) charging technology, which allows for precise adjustment of the charging power and speed to the device, preventing battery damage. The power bank features short-circuit protection, shock protection, over-current protection, and overcharge protection.
