With your portable solar panel, you’ll be able to charge multiple devices. However, it’s important to understand how to set up your device in the correct way.

Let’s say you’re on a camping trip. You have your portable solar panel, a set of wires, a charge controller, a battery pack, and an inverter. Once you’ve determined the power size, you’ll need to establish the connection in a parallel or a series – this depends on the voltage and current requirements of your charge controller. While the parallel connection adds current, the series connection adds voltages.

Once you’ve connected the terminal outputs, you’ll also have to connect the charge controller input to each terminal output. Connect your terminal outputs to the energy storage device. While doing this, you’ll need to make sure that the controller’s voltage output is the same as the battery pack’s nominal output. Once you’re done with establishing the battery connection, you’ll be able to wire the power AC loads to the battery-based inverter.

Things are much less complicated with the best portable solar panels that are designed to charge phones and similar devices specifically. They look appealing and are very easy to use, letting one charge his smartphone via USB ports.

Designs vary from best solar panels that look like tablets to those that fold down like an accordion. Some models allow charging multiple gadgets at once, such as your Bluetooth speaker, external battery, camera and others.
