Recently a customer called us and asked, “How do I compare costs of portable solar chargers?”

That is a good question as you work through the maze of solar chargers. How do you “normalize” the price.

If you look at the cost per Watt, you can get a good idea of the relative value and compare solar chargers. So for example the SunJuice is about $7.79/Watt, although the total price is $59.99. It’s very simple to take the total price and divide in the total watts. If anyone wants us to calculate this for them on any charger they are considering just let us know.
