FAQ

Is there a promo code?

Yes. Enter capitalone12 at Harfington checkout when buying the Harfington 5 W USB mini solar panel, 5 V 1 A for 12% off.

Can it charge a phone directly?

It supplies USB power in direct sun, but the page says to pair it with a battery to store energy. With changing light, charging a power bank first is the steadier route.

Can I return it?

The product page offers 30-day returns from delivery. Returns are free within the US; elsewhere you pay the return shipping.
