PV Gap

Judy Said:

What is mAh and its purpose because I want to buy a solar charger so I can charge my gadgets while @ the beach?

We Answered:

mAh means milliamp-hours. It is a measure of a battery's energy storage capacity. It is the current in milliamps (mA) that can be drawn from the battery multiplied by the time in hours that the battery will last at that current. So, for instance, a 1,000 mAh battery could supply 1,000 mA for 1 hour, or 100 mA for 10 hours.

If the solar charger has a mAh rating, then it must have an internal battery, like this one does:

This means you can leave it in the sun soaking up energy while you are using your equipment. Then when you plug in your device to the charger the energy in the charger's battery will be transferred to the battery in your device.

So, what you want ideally is a charger with a mAh rating which is equal to or greater than the mAh rating of your device. That way a full charge in the charger will fully charge your device.

Alternatively, if you want to charge by having the charger sitting in sunlight charging straight to the device, then the mAh rating of the charger's battery is irrelevent, because the energy is going straight into your device.

Hope that makes sense!

PS. It goes without saying that the voltage output of the charger must be set to the input voltage of your device. The only way you can damage something with a solar charger would be if you set the voltage too high.
