Harness the sun’s power today!

" The BigBlue 28W USB Solar Charger produces the most power of any portable solar charger we’ve tested, and it has unique features that make it more versatile and durable, including three output ports (versus two on most other chargers), and an expansive but lightweight array of panels to catch every last ray of sunlight. Smaller and lighter than other options with similar output, so it can more easily fit into a camping backpack, hiking daypack, or emergency kit." -- By Wirecutter Editor

1. Place the solar panels in direct sunlight (full expansion required). For windows: Hang outdoors (never behind glass – blocks 25% sunlight!).
2. Connect your device (phone, power bank) to the USB port of the solar charger. Charging starts instantly – no buttons!
3. Note: This solar panel charger does not have a built-in battery and cannot store electricity - It does not function at night or in low-light conditions.

Best Performance Tips

✔️ Keep the solar panel stable, clean, and shaded-free during use.

Overheat warning:

✔️ Place your phone or power bank in shade (e.g., under trees) while charging

High-quality Solar cells

✔️ Reducing heat buildup, making solar panel charger more robust and less prone to damage, which extends their lifespan. Without metal lines on the front, these cells capture more sunlight, enhancing electricity generation and providing a sleek, modern design.

The maximum output of each port is 5V/3A, BUT the real outputs are related to the sunlight intensity, temperature, angle, shadow, etc.

We discovered that many families still suffer from energy problems. People have to choose the bulky and environmentally unfriendly generator.
