Technical FAQs 4

How many Watts should a solar charger charge?

Once you get an idea of charging capacity and your intended use for a solar charger, it's time to figure out what devices you plan on using. For smaller handheld items such as smartphones, a solar power bank with five to fifteen watts should suffice.

How to choose a solar charger?

Make sure to place your panels in ideal locations to capture sunlight and avoid running out of juice sooner than expected. Features such as kickstands and legs can help create a more optimal angle for charging. Choosing the right location for your solar charger can make a big difference in charging capabilities.

Which flex solar charger should I buy?

The FlexSolar 40W is a high-output model that easily unfolds from the size of a large book into six solar panels. This is our top recommendation for those seeking an easy-to-use and set up solar charger with a DC output, capable of putting out 19 watts, for larger portable power stations.

How long does it take to charge a solar panel?

After a full week, the battery will be just about fully charged. Using this example, you can see that it will take at least 100 watts of solar power to recharge a 100-amp hour battery in a few days. Also, keep in mind that it takes direct sunshine on the surface of the panel to produce the maximum-rated power of a solar panel.
