1. Why the connected device cannot be charged?

Please check if your device is well connected to the solar charger or if the connecting cable works normally. Re-plug the cable or try with another cable.

2. Why the connected device is charged slowly?

Ensure that the input current and voltage of the connected device are within the accepted range. The amount of sunlight, weather, or shady may cause fluctuations in the current output that prevent your devices from charging. In this event, try placing the solar charger in more direct sunlight or wait for the weather to clear. In order to get the maximum solar energy, please adjust the solar charger toward the sun.

3. What is the difference between the nominal / rated output from the actual output of the solar charger?

The maximum nominal / rated output of the SolarPowa 28 solar charger is rated based on the Standard Test Conditions (STC) – the industry-wide standard for the conditions under which a solar panel is tested. The test conditions are defined as irradiation 1000 W/m², temperature 25°C, and air mass 1.5.

The nominal / rated power refers to the power of the solar charger, which is not equal to the actual output of the solar charger. In fact, the actual power is less than the nominal / rated power, since there will be some power loss in the form of heat during the solar energy conversion, and a few other environmental factors such as the weather conditions, seasonal changes, and location.
