10000 mAh 120 W Wireless Power Bank  (Yellow, Lithium-ion, Power Delivery 2.0 for Earbuds, Laptop, Mobile, Speaker, Smartwatch)

This solar power generation system is an all-round portable energy storage power supply that integrates high power output, fast charging and multimedia entertainment.Its core uses a high-energy-density 3-string polymer lithium battery pack to provide a strong and long-lasting power reserve. The system design is highly integrated and user-friendly. It supports three flexible charging methods, including solar energy, household mains electricity (100-240V global wide voltage) and Type-C, and is adapted to the electricity consumption environment in different regions of the world.Its powerful output matrix includes a USB interface that supports 3.1A high current, a DC output port with a peak power of 126W, and a cigarette lighter designed for on-board equipment, which can efficiently power notebook computers, drones, on-board refrigerators, lighting equipment and a variety of digital products at the same time. In addition to excellent power supply capabilities, this product also has a built-in advanced Bluetooth 5.3 audio module, a full-band FM radio, and supports SD card/U disk local playback. It can be transformed into a high-quality 2W stereo speaker at any time to meet the needs of outdoor entertainment and information acquisition.Multiple circuit protection mechanisms run through the whole process of charging and discharging to ensure the safety of users and equipment. Product selling points (refined based on new parameters) Strong output, multi-device charging at the same time： USB fast charging: Dual USB-A ports, single port supports up to 3.1A output current, which can provide fast charging for mobile phones and tablets. High-power DC output: The DC output port supports a maximum current of 10A (voltage 9-12.6 V), with a peak power of more than 120W, which can directly drive or power most notebook computers, photographic equipment, drones and other equipment. Special cigarette lighter for on-board equipment: provides 5A constant/10A maximum output, specially designed for on-board refrigerators, air pumps and other equipment, and the power supply is stable and reliable. Triple smart fast charging, flexible and efficient： MAINS fast charging: support 100-240V global wide voltage input, strong versatility.Equipped with a 12.6V/1A dedicated adapter, high-efficiency charging. Type-C PD fast charging: The Type-C input port supports 5V-9V/2A input. It can not only be charged with solar panels, but also use common PD chargers to quickly replenish power. The maximum charging current can reach 900mA, which replenishes power more quickly. Solar charging: compatible with solar panel charging to achieve outdoor energy self-sufficiency. Multifunctional entertainment center, outdoor is not boring： Integrated Bluetooth 5.3 module, stable connection, low power consumption, and wireless playback of mobile phone music. Built-in FM radio (76-108MHz), you can also listen to news and music in a network-free environment. Support SD card, U disk direct reading and LINE IN audio input, and provide a variety of audio source playback options. 2W stereo speaker output, providing clear and full external sound. All-round safety protection, more peace of mind when using electricity： Output protection: The USB port has short-circuit protection, and the output is automatically turned off when it fails to prevent equipment damage. Charging terminal management: Adopts constant voltage/constant current charging mode, with voltage cut-off protection, which effectively prevents battery overcharge and extends battery cycle life. Circuit-level protection: The system integrates multiple protections such as overcharge, over discharge, and overcurrent (based on the original document) to ensure safe use. Core high-performance battery compatible with wide voltage： It adopts a 3-string polymer lithium battery pack with high energy density and an intelligent battery management system, which has an excellent energy efficiency ratio. The MAINS input terminal is compatible with 50/60Hz power grid frequencies, and can be plug and play in most regions of the world, so there is no need to worry about compatibility issues.
