What can a 400W panel realistically charge?

In good direct sun it can feed a mid-to-large portable power station fast enough to refill it in a day, and it can run laptops and phones through USB-C. Real output is usually well below the rated 400W because of heat, angle and haze.

Does it work with any power station?

It works with power stations that accept the panel's DC output voltage and connector, and with solar charge controllers on a battery setup. Check your station's input voltage range and plug type before buying.

Can I connect two panels together?

Yes. The panel supports series and parallel connections, so you can pair units for more voltage or more current. Match panel models and check your station's limits before wiring them.

Is it waterproof enough to leave outside?

The panel materials are described as waterproof and durable, so light rain and splashes are not a concern. It is still a folding panel, so bring it in during storms and store it dry.

How portable is it really?

It folds into a carryable package, but a 400W panel is large and heavy for one person to haul far. It suits car, van and basecamp use more than hiking.

What comes in the box?

You get the folding solar panel itself with its built-in output ports and connection cables. A power station or charge controller is not included and is needed to store the power.
