2W 5V USB Solar Panel Charger: Compact 157 x 94mm PET Panel for Direct Sunlight Device Charging

This portable solar charging solution converts sunlight directly to 5V USB power for compatible electronic devices. The 2W panel measures 157mm by 94mm and utilises A-grade polycrystalline silicon chips in an EVA laminated construction. With a working current range of 0-400mA, it provides sufficient power for charging mobile phones, operating small fans, powering flashlights, and supporting monitoring equipment when exposed to direct sunlight. The included 50cm USB cable offers connection flexibility, while the PET material housing ensures a lightweight, portable design suitable for outdoor activities, emergency preparedness, or supplemental power applications where grid electricity is unavailable.

Features and Construction

The solar charger combines compact dimensions with practical power conversion capabilities. Measuring 157mm x 94mm, it occupies minimal space while delivering consistent 5V output through its USB interface. The EVA laminated integration process creates a durable assembly that maintains performance under typical outdoor conditions.

Material and Build

The panel utilises PET material for its protective housing, providing a lightweight yet resilient exterior. Inside, A-grade polycrystalline silicon chips perform the solar conversion, transforming sunlight into usable electrical current through the EVA laminated integrated process. This construction approach ensures components remain securely positioned while allowing for efficient heat dissipation during operation.

Size and Practical Fit

With dimensions of 157mm by 94mm, the panel fits conveniently in bags, backpacks, or alongside equipment requiring charging. The 50cm USB cable provides sufficient length to position devices comfortably while keeping the panel in optimal sunlight. This combination of compact panel and adequate cable facilitates practical deployment in various settings, from backpacking trips to temporary outdoor workstations.

Uses and Placement

The charger supports multiple electronic devices within its 3.6V-5V compatibility range. Its direct sunlight operation makes it suitable for scenarios where traditional power sources are unavailable or impractical, providing a renewable energy alternative for maintaining essential device functionality.

Event or Professional Use

For monitoring devices, outdoor equipment, or temporary installations, the solar charger offers independent power without requiring electrical infrastructure. The consistent 5V output supports standard USB-powered devices commonly used in field research, security monitoring, or remote data collection. When paired with appropriate external batteries, it can extend operational periods beyond daylight hours for professional applications.

Everyday Home Use

For household applications, the charger provides emergency power during outages or supplementary charging for portable electronics. Mobile phones, LED flashlights, USB fans, and similar devices benefit from the renewable energy source during daylight hours. The straightforward operation requires only sunlight exposure and proper device connection via the USB interface.
