IP65 waterproof rating, but the USB interface and ammeter are not waterproof, so please keep it away from water when charging..2. Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.3. The use of the product is affected by the light intensity and Angle, and the best charging efficiency can only be played under the condition of strong light and direct sunlight.4. The optimal Angle is the solar panel surface at 90 degrees from the light.5. Low light intensity, bad Angle of solar panel, dark cloud shadow, shade, insulating glass and other environments will affect its charging efficiency.
