5V 2A Solar Panel USB Voltage Regulator Controller Module

5V 2A Solar Panel USB Charge Voltage Controller Regulator

Keep your devices powered anywhere the sun shines with this compact and efficient 5V 2A Solar Panel USB Voltage Regulator. Designed for DIY solar charging setups, power bank projects, and off-grid electronics, this little module delivers a stable 5V output from a wide range of solar panel inputs — all in a package barely larger than a postage stamp.

Key Features

• Automatic Device Identification: Intelligently recognizes smartphones, tablets, cameras, and other USB-powered devices for optimized charging.
• Stable 5V Constant Output: Converts variable solar input (5V–20V) down to a clean, regulated 5V — no voltage spikes to worry about.
• Auto-Restart Function: Automatically pauses when sunlight weakens and resumes charging once strong sunlight returns — fully hands-free operation.
• High Conversion Efficiency: Up to 95% conversion efficiency means more energy from your solar panel reaches your device.
• Wide Compatibility: Works with most smartphones, tablets, iPads, digital cameras, and USB-chargeable devices.
• Compact Form Factor: At just 3.5 × 3 cm (approx. 1.38" × 1.18"), it integrates easily into custom enclosures, backpacks, and DIY builds.
