Let’s talk about the Rockpals 300W Portable Solar Generator, shall we? It’s one of the most popular portable solar generators on the market at the moment, so it only seems fitting that we should review it. Similar in looks to the Goal Zero Yeti, it is a very impressive model that boasts a number of features that work well in an emergency or power outage. 

Its small and compact design pairs well with its slight weight to make it an excellent transportable generator that you can take almost anywhere. Want to go camping but don’t want to completely cut the power? Or maybe you’d like to try living off the grid to become more environmentally conscious? Then this is a great option for you. 

Rockpals offer a number of solar power stations that vary greatly in wattage and price. You can get a generator offering only 100W, but this may struggle to keep up with everyday family needs, or one that boasts 500W. However, the 500W model compromises the portability and low price of the generator, which is why we think the 300W model is a great choice as it offers enough power without becoming too bulky or heavy.  

The Rockpals 300W Portable Solar Generator is plenty powerful in itself - so much so that you’d be able to charge your phone at least 25 times easily as well as a laptop about five times. Or you could watch 32 inch television for around four hours without running out of power.

Here we’ll summarize the Rockpals 300W Portable Solar Generator. Below we’re looking through the specifications for this model and how this will benefit you should you choose this design. 

For a 300W portable generator, this is an excellent model from Rockpals. It boasts a 75Ah battery at 3.7V, as well as an impressive total capacity of 280W hours. The internal 300W Pure Sine Wave Power Inverter could easily peak at 600W, offering a constant output of energy to make sure you’re not caught in a power cut. 

It could definitely be used to keep your household afloat during a power outage or an emergency, however 300W will only go so far so it is not feasible to be used to run a whole house constantly. However, you could also use it while living off the grid to live more environmentally friendly. 

The Rockpals 300W Portable Solar Generator features a single AC socket and five DC outlets to charge your most important possessions. Moreover, it has five USB ports, two of which are 2.1A and two are quick charging 3.0 ports, to charge things with USB wires. On the whole, this generator offers enough outlets to keep your vital appliances going. 

This portable generator is a small  6.5 x 3.1 x 6.9 inch cube of pure power. Along with its mere weight of 7.5 pounds, this is an excellent device to take with you on all sorts of adventures and excursions, such as camping, long hikes and RV holidays. This is just one of the reasons why it is one of the most popular portable solar generators on the market. 

Compatible Chargers

There are many different chargers on the market that are compatible with the Rockpals 300W Portable Generator, which is a big plus as if you already own one, you may not even have to spend any more money. Rockpals even offer a variety of different chargers for your generator, all with different price levels and outputs, so you can choose which best suits you. 

A foldable solar charger with a portable power station is always an excellent option as you can take it anywhere and everywhere, enjoying endless solar power to keep your device fully charged (as long as it’s sunny, of course). Many of the solar chargers that Rockpals offers can be folded to the size of a bookbag with a nifty handle for the ultimate easy transportation.

One solar charger Rockpals offers is the Foldable 60W Solar Panel Charger. It uses its four highly efficient solar panels to draw in as much sunlight as it can to keep your device up and running. In fact, it’s designed to convert up to 23.5% power. It’s waterproof and very durable so you won’t have to worry about taking it on many adventures deep in nature. 

It’s also super easy to carry around thanks to the handle and clasps to keep it folded, and it comes with multiple different connectors to use it with more than just your generator. You can use it with brands such as Jackery, Webetop and GoalZero, making it very versatile. Moreover, it has 3 USB smart charging technology so you could charge other devices such as your phone. 

While this charger may be slightly on the expensive side, it’s better to be safe than sorry and choose a high quality charger that you know is going to provide you with plenty of charge over the years, than to get a cheaper alternative that you may find you need to replace quite quickly. 

Why Should You Buy It?

There are many reasons why the Rockpals 300W Portable Solar Generator is an excellent choice for you, however we have condensed it to three impressive facts about this machine that are sure to sway your decision. 

  1.  It is a reasonably powerful solar power station for a great price

Compared to other models of similar structure and price on the market, Rockpal’s solar generator offers out a great amount of power to keep you connected. It’s full capacity of 280Wh works with the high quality lithium battery to make sure the power doesn’t run out.

As we mentioned before, you could easily watch your favorite shows on a 32 inch television for four hours, or keep your food cool in a mini fridge for five hours. Similarly, if you need it for a more serious reason, you could also easily run a CPAP sleep apnea machine for four hours. 

The Pure Sine Wave Power Inverter keeps a clean flow of steady energy to all the outlets, and thanks to the AC socket, you could power most of your AC appliances through it in a breeze.  

  1. Lightweight and portable design

Thanks to the lightweight and compact design Rockpals has chosen to use with this solar generator, you can take your model almost anywhere that you may need a little bit of power. This means that if you find yourself or a friend in an emergency, you can easily transport your generator to wherever it’s needed most. 

Even though it may not have the highest power output on the market, the fact that you can take it with you anywhere really makes up for this, along with its other notable features. 

  1. Many different power options

The Rockpals 300W Portable Solar Generator comes with a number of charging options, despite a singular 120V AC outlet. We’ve mentioned earlier that it also includes five DC ports, four of which are 12V and one is 24V, and four USB ports, two being 2.1A and the others being quick charging 3.0 technology. 

Why Shouldn’t You Buy It?

While this machine has its many benefits, there are also a few drawbacks. For instance, this 300W model isn’t the most heavy duty generator out there, so it may not live up to your expectations if you need more wattage. Another setback is that it only has one singular AC socket which may be a problem if you want to run more than one AC appliance. 

Another thing to consider, however obvious it may sound, is that the Rockpals 300W Portable Generator runs on solar energy. This means that if you live in a place where it often rains or is overcast a lot, your generator won't be getting much sun to be able to turn into energy. You may find your generator out of power because of this, so if you live in one of these areas, you may want to find a model with larger solar panels. 

If you want a solar generator to cover all your needs while living comfortably off the grid, or reside in a place that doesn’t see as much sun as it does rain, the Rockpals 300W Portable Solar Generator perhaps isn’t the best model for you. 


There are many features that come along with the Rockpals 300W Portable Solar Generator - way too many to write down in this one small article - so we’ve summarized and only chosen the most impressive. We’ve gone through a lot of these earlier in the article, but every article needs a Too Long; Didn’t Read section, right? 

Not everyone has time to read this whole article, which is why we’ve condensed the highlights into this bulleted list. The features of this portable solar generator that stick out to us the most are: 

  • Five DC outlets and four USB ports so you’re not stuck having to use multiple extension cords to keep everything running.
  • Super lightweight and portable with a weight of only 7.5 pounds.
  • 300W Pure Sine Wave Power Inverter which has the ability to peak at up to 600W.
  • Compact cube shapes of 6.5 x 3.1 x 6.9 inches won’t take up too much space and won’t become an eyesore in your house.
  • Large display to keep you in the know of what’s happening with your generator.
  • Powerful 75000mAh 3.7V/12V 18750mAh lithium battery built-in that won’t need replacing any time soon.
  • A powerful 280 Watt-hour solar power station that manages to remain silent while powering your house.


And that concludes our view on the Rockpals 300W Portable Solar Generator. As you can see there are many reasons why this is a great portable solar generator for you to invest in, such as the transportation abilities, the multitude of ports to charge multiple devices and appliances at once, and how much power it has the potential to peak to. 

Having said this, nothing is perfect and there are also a few setbacks to the Rockpals generator. Obviously, a 300W generator won’t be able to power your whole house 24/7, and you may only be able to use it for one or two high powered appliances at a time. Moreover, you will not be able to use it continuously if there is no sun so it’s very weather dependent.  

To summarize, this generator is great for transportation with many different outlet options and enough power to keep your household going in an emergency situation. As long as you have a reliable charger, this solar generator will not let you down.
