Powerful 36800mAh Power Bank with Solar Charging, QC 3.0, Dual USB Ports and Flashlight (Black)

In 2014, founders Bard and Daniel established the brand "Mregb" after noticing the increasing anxiety of mobile device users regarding battery life, as smartphones and various portable electronics gained popularity in recent years. Mregb's core purpose is to provide users with high-quality, durable, and cost-effective power banks to address their concerns about battery power.

The Solar Power Bank 42800mAh model offers several key features. It has a built-in smart chip that can automatically identify all USB devices on the market and adjust the voltage and current to ensure compatibility with different devices, such as iPhones, Samsung phones, tablets, cameras, and more. The power bank uses a safe and reliable high-density lithium polymer battery, which is compact in size yet has a large capacity. A built-in security chip stabilizes the voltage and current, and controls the temperature to provide safe protection.

For convenience, the power bank includes a precisely calibrated compass, integrated without the need for additional carrying. This can help users find their way when outdoors, preventing them from getting lost. The LED indicator can accurately display the battery power, making it easy to monitor the remaining charge during use.

The product offers two charging methods. While it has a solar charging function, the large battery capacity and limited charging power of the solar panel result in a very slow solar charging speed. This solar charging feature is intended for emergency use only. It is recommended to use a charger of 5V2A or higher to charge the power bank in normal circumstances.

The Solar Power Bank 42800mAh is designed to be waterproof, drop-proof, and dustproof, with an IP67 protection rating. It is made of high-strength ABS material, allowing it to withstand falls from high altitudes and function normally even in extreme environments. Additionally, the built-in flashlight can stay on for more than 80 hours, potentially aiding users in emergency situations.

The compact design of the power bank includes a hook and carabiner, enabling users to conveniently attach it to their backpacks while camping or traveling. The solar panel allows the power bank to recharge itself under direct sunlight, providing a source of electricity when there is light available.

The power bank's specifications include a Li-polymer battery, a 5.5V/400mAh solar panel, and ABS+PC+Silicone materials. It has an input of 5V/3A and an output of 5V/3.1A, with a charging time of 8-10 hours and an operating temperature range of -10°C to +60°C. It can withstand up to 1800 charge and discharge cycles, ensuring a long lifespan.

Owning this solar power bank allows users to travel, work, or engage in outdoor activities without worrying about their devices running out of power. It provides a reliable and versatile solution for maintaining connectivity and access to essential tools, even in remote or off-grid locations.
