Compact USB solar charger

The crystalsolar 5.5W panel delivers 5V at 860mA through a single USB port, making it a lightweight power source for phones and small tablets during outdoor activities. Its polycrystalline silicon cells are laminated with PET and EVA for durability while keeping the folded size to 210mm by 165mm. Weighing 210g, it slips into a backpack for camping, hiking or emergency kits.

Steady output in sunlight

Under continuous direct sun the panel maintains its rated 5.5W output rather than peaking briefly, so connected devices charge at a consistent rate throughout the day. The 17% conversion efficiency means usable current arrives even when the sun angle shifts, reducing the stop-start cycles that can frustrate phone charging logic. No internal battery stores energy, so output follows available light in real time.

Passive cooling and rugged build

With no moving parts the charger runs silently and draws zero power when not in use, while the laminated surface resists water splashes and dust encountered in garden or agricultural settings. The thin 5mm profile dissipates heat across the whole panel area, keeping cell temperature stable during extended operation. No fan noise, no coil whine, just solid-state energy harvest.

Questions about this item

Does the 5.5 W panel get hot or make any noise when it runs all day in the sun?

The panel has no moving parts and produces no audible noise; it simply warms to ambient temperature while converting sunlight at a 17 % rate.

What cable or device must I already have to charge my phone from the USB port?

You need a standard USB-A charging cable that matches your phone's connector; the panel supplies 5 V at up to 860 mA directly from the port.

Will the 5 V USB output work safely with an older feature phone that only accepts slow charging?

Yes, the port delivers 5 V at a maximum of .86 A, so older handsets draw only the current they require without risk of over-voltage.
