What can the Renogy 400W panel charge?

It connects through IP68 connectors to most portable power stations rated 200-1500W. It does not charge a battery bank directly without a compatible charge controller.

How much does it weigh?

About 30.2 lbs. That is manageable for car camping but heavy for long carries on foot.

Renogy rates it at least IP67, with an ETFE coating and aluminum backsheet. It is built to handle rain, snow and hail, and temperatures from -40°F to 185°F.

How efficient are the cells?

Renogy claims over 23% efficiency from EL-tested Grade A+ monocrystalline cells with 16BB busbars.

What warranty comes with it?

A 3-year warranty that can be extended to 5 years, plus a 10-year guarantee of at least 80% output.

Does it work in shade?

Only partly. Like all panels, output falls when cells are shaded, so aim for open sun.

Our take on the Renogy 400W Portable Solar Panel 16BB

The Renogy 400W Portable Solar Suitcase is a folding two-panel array built for camping, RV trips and backup power. It uses Grade A+ monocrystalline cells with 16BB busbars and claims over 23% efficiency, packed into a 30.2 lb frame that Renogy says is about 30% more compact than typical 400W panels. Aluminum kickstands set it up in about a minute, and IP68 connectors link it to most portable power stations rated 200-1500W. Against folding rivals like EcoFlow and Jackery, it offers more wattage per panel and a tougher ETFE and fiberglass build, but it is heavier than 200W suitcases and needs full sun to hit its rating.
