Portable Solar Panels come with a simple jack or set of jacks to output power to a variety of devices. You're likely to find a DC output jack and a USB port, allowing users to directly charge phones or laptops. Most often, portable solar panels are paired with a portable lithium-ion battery so that their energy can be used under any conditions.
On the other hand, setting up a portable solar panel takes minutes, needs no permits or inspections, and there's no worry about damaging your roof.

Portable solar panels are small, plug-in panels that you can take anywhere with you. Unlike mounted units, portable panels can't power an entire home, but can be used to charge small electrical appliances, such as phones, laptops, or even microwaves.

Here's how solar panels work:
You can channel this electricity (DC) through a charge controller and into a battery. Next, you'll use an inverter to change DC power into AC power to charge your electronic devices. However, some portable solar panels don't need an inverter or charge controller.

If you don’t require a large amount of energy or want to supplement your existing stationary setup, portable solar is right for you. It’s great for those who love to venture off the grid but can’t or don’t want to lug around bulky generators.
