Goal Zero Ranger 300 Briefcase: High-Powered 300W Folding Solar Charger in Briefcase Form

We are familiar with a wide range of 100W and 200W briefcase solar panels. We have covered the best sellers of both in two listicles here and here. What about a 300W foldable, briefcase solar charger? That is from Goal Zero, one of the biggest players in the portable solar power market. It is Goal Zero Ranger 300 Briefcase.

Goal Zero is already famous for its two series of solar panels; Boulder and Nomad. The first one is regular glass and metal solar panels, whereas the second one is a line-up of purely fabric-based folding solar panels. Both the series are available in multiple power options.

The new Ranger series has something really special as it incorporates the attributes of both Boulder and Nomad solar panels. That is, the first variant in the Ranger series comes out in a combination of solid aluminum frame and ETFE polymer solar panel instead of glass.

That is how we are lucky to have a big solar panel with more power and less weight.

Perfectly, it can harness more power from the sun and make your outdoor or survival life more reliable. You can pair it with the brand’s Yeti 1000X power station and bigger models for ultimate off-grid power.

Goal Zero Ranger 300 Briefcase

The Ranger 300 Briefcase is made of four pieces of 75W highly efficient mono solar panels. They are perfectly paired together with quality hinges and so it is easy to fold, carry and store in a much convenient way.

It highlights a thin but solid aluminum frame and ETFE polymer. As there is no use of glass, the Ranger 300 is three lbs lighter than Boulder 200 but is able to offer you 100 watts more solar power.

Well, you get the new Ranger solar panel with a patent-pending kickstand design. That helps the kickstands fold out automatically as you open up the panel, making it a really amazing choice for outdoor use.

Further, it integrates solid handles and magnetized corners to make it further portable and safe.

Specs-wise, Goal Zero Ranger 300 Briefcase features a high-power port of 14-23V, up to 21A (300W max). It has a folded size of 30.6 x 26.3 x 3.8 in, while it measures 30.6 x 105.9 x 0.9 in once unfolded and it weighs 39 lbs.

It carries a price tag of around $800 as of writing this article.

The Goal Zero Ranger 300 Briefcase Competitors

Though a rare piece, the 300W Ranger solar charger has got a couple of competitors on the market.

They are from the leading brands Lensun and Dokio. We would like to have a look at their 300W folding solar panels and check out how competitive they are with the Goal Zero product.

Lensun 300W Foldable Solar Panel

It is a four-layered folding solar charger with a high conversion efficiency of up to 22%. The lightweight and ultra-slim solar charger is an ideal choice for outdoor use, thanks to its waterproof and durable design.

It has a smaller size compared to the Ranger panel as it features a folded size of 27.2 x 27 x 3 in and unfolded size of 106 x 27 x 0.8 in. With no metal framing, its weight is also quite lighter at 24 lbs.

A strong kickstand and fabric handles are other attractions. It touts ETFE coating for great durability and corner protectors for safe moving and rough outdoor use. Check out the product on the link below.

The fabric-based solar panel is made of seven layers for extra durability and perfect heat transfer. The 1.2mm fiberglass back sheet gives it further strength to be one of the coolest, high-powered folding solar chargers.

You can use it with any of the market’s solar power stations. Instead of using multiple panels, it can be a superb choice with most of the mid-range solar-based power stations.

Coming up with a 30A solar charge controller, 16-ft extended cable, and battery clips, it is also an ideal choice for charging your regular battery packs under the sun.

Dokio 300W Solar Panel

Dokio has got yet another competitor to the Goal Zero Ranger 300 Briefcase.

This is also a four-fold mono solar charger with a quality build and increased conversion rate. Once folded down, you will get a briefcase-like form so that its handling will be quite easier out in the wild.

Compared to both the above models, this is the lightweight, thinnest, and smallest most. With a foldable size of 21 x 41 x 1 in, the Dokio solar charger weighs just 17 lbs. That is what makes it an amazing portable solar panel to pair with your power stations and other off-grid power systems.

The solar charger comes with a smart PWM charge controller that integrates dual USB ports. This is the way you can use it to charge a variety of your 12V batteries under the sun.

Dokio offers solar chargers in different power options. Thanks to the extremely thin profiles, you get some of the coolest folding solar chargers from the brand.

Final Thoughts

That has been our take on the Goal Zero Ranger 300 Briefcase. Goal Zero seems to have come up with the new series with a fusion of the features of both the metal and fabric-based solar panels.

Being a pioneer in the portable power market for a long time, Goal Zero can indeed attract a lot of customers with the powerful 300W solar panel and you can use it to power up your bigger power stations more quickly.
