Goal Zero Ranger 300 Briefcase Solar Panel (Open Box)

This is a beast. It's heavy, but it's built like a tank. It charges my Yeti 1500X in a few hours. Even though it's open-box, it looks and works perfectly.

I love the output – 300W is no joke. But it's big and awkward to carry around. The briefcase design is nice, but I wouldn't want to hike with it. It's better for home backup or RV use.

We use this for our RV trips. It keeps our batteries topped up during the day. The build quality is impressive, and the kickstands are sturdy. Highly recommend.

The panel works wonderfully, but since it's open-box, it didn't come with any manual. I had to figure out the connections on my own. Online guides helped, but it would have been easier with instructions.

I tested it against my old 100W panels and this thing is a workhorse. It's heavy, but that's a trade-off for the power. It's already powering my workshop.

It's a good panel, but for the price, I expected it to be in better condition. The case has some scars and the panel has a few micro-cracks (minor, but visible). Performance is still fine, but I'd rather have bought new.

I've used many solar panels, and this is by far the most efficient. It even works well in low light. The build quality is top-notch, and the case protects the panels when not in use. Worth every penny.

This panel is heavy – you'll feel it carrying it more than a few feet. But the power output is incredible. For stationary use, it's perfect. Just don't expect to backpack with it.

I was skeptical about open-box, but this is barely used. It charges my power station in record time. The kickstand is sturdy, and the connectors are solid. Very happy with my purchase.
