Renogy Portable Solar Generator Review – The Almost Perfect Solar Generator

First, My Goal Here, Plus a Little Background….

In this article, I want to touch on the features of Renogy's multi functional portable solar generator, and discuss the good and bad points of this product. I will also compare it to its leading competitors and give my final recommendation.

We Floridians frequently lose power. Okay, our grip on reliable grid power is not as tenuous as, say, the average third world country, but during the peak summer storm season, it can sure start to feel like it! Frequent blackouts are more than just annoying, they disrupt your routine, throw your schedule into disarray, cause millions of dollars in property damage, lost productivity and are a basic hazard that must be planned for and dealt with, sooner or later.

When we first moved to the rural area in Florida where we have lived for the past twenty-five years, we lost power each and every day in the summer. We went from asking ourselves, ‘Will we lose power today', to, ‘How long will we lose power today'?

Based purely on crazy coincidence, I soon became interested in portable, sustainable, electric power generation. I may not know everything there is to know about the portable solar generator, but I have a (self-awarded) degree in the study of power blackouts.

A couple of important developments have occurred in the last several years which together make the portable solar generator a viable option for anyone looking to replace a small, gas powered generator with a silent power-pack and its potentially unlimited power generating ability.

The first is battery technology, specifically the lithium ion and/or lithium polymer battery. This battery technology, while still relatively expensive, is vastly superior to the lead acid, and nickel based batteries we were stuck with in the past. The best thing about Lithium batteries is their flat power curve. This is best illustrated by visualizing the simple cordless drill.

Remember your old drill, the one with the NiCad or Ni-MH battery? That sucker was pretty handy when brand new, but as you operated it and charged it a couple dozen times, you began to experience a peak in charge capacity and, therefore, discharge ability. Crystals, called dendrites, were beginning to form in the battery and a ‘memory effect' was beginning to take root.   

This old drill slowly began to lose charge capacity and it slowly but steadily lost power output over time.

Besides lost output capacity, as you were using the drill, you would know it was running out of ‘juice' because the RPM's would start to drop and we all would try to nurse the thing along to get that last possible screw counter-sunk before giving up and finding the charger. A few hours later, the battery was recharged enough to turn a few more screws.

Lithium Ion to the rescue! This technology has given us a battery without the memory effect, so plugging in a half-charged battery into the charger is no longer detrimental to its service lifespan. Lithium batteries tolerate a much wider temperature range and as a bonus, are much lighter than other batteries of the same rated voltage.

Lithium battery tools are great because they deliver full power right to point where they just stop. This is due to their built-in protection circuit which is there to maintain safe operation by limiting cell peak voltage during charging, and floor voltage during discharge.


The second important area is the development and cost of the solar panel.

Since the first practical implementations of the photo voltaic cell in the 1950s for the space program, solar power technology in the U.S. alone reaches close to seven million households, and millions more retail and commercial facilities.

Over the last ten years, the cost of solar panels has declined by approximately 60 percent, which has brought their price per watt of energy down to a very attractive level, and the cost trend, despite tariffs on Chinese panels, still points down.

Today, there exist many portable solar panel options, with panel efficiency in the 15 to 20 percent range. Simply put, it has become affordable and convenient to pack 100 watts or more of portable power to take along with you on your weekend camping trip.

What's So Damn Great About Your Precious Renogy Products?

Sure, there are many companies out there producing products for the solar power industry, but Renogy stands out for me due to their consistent quality, value and their great service.

Renogy was actually started by students at Louisiana State University and together with the Louisiana Business and Technology Center has, as of 2014, earned a spot on Inc. 5000's top 500 fastest growing private companies.

When you study their product line, from solar panels to charge controllers, inverters, batteries, even installation kits, you will notice that the quality is evident and the price is competitive. Personally, unlike lots of other companies in the solar industry, I believe that money spent purchasing Renogy products is a safe investment. I don't want regrets, I want value and Renogy has always delivered.

Renogy Rugged Power Pack – Multi Functional Portable Solar Generator

Renogy Rugged Power Pack 400w

Renogy actually has a line-up of these portable power packs, but the 400 watt hour system, pictured above, is likely the best for most practical situations. This is due to its lightweight, (18 pounds), power output (600 watt peak), and incredible versatility.

This unit is bristling with connectors for everything from a 12 volt socket, to 5 volt USB as well as 110 AC. It features a built-in inverter, although it is modified sine wave, and even built-in charge controlling.

So, not only is it easy to tap into this power pack, it is easy to keep it charged while away from home!

This is because Renogy ships these generators with an AC wall charger, 12 volt car charger and best of all, a solar charging cable. The thing is built for power, both incoming and outgoing.

Check out their list of features:

What else is in this price range?

Here are three direct competitors:

SUAOKI Solar Generators, G500 Portable Power Station 500Wh Camping Generator Lithium Battery Pack Power Supply with 110V/300W (600W Peak) Pure Sine Wave AC Inverter for CPAP Emergency Outdoor

Suaoki Solar Generator

The Suaoki is, on paper, possibly the most worthy contender here. It has similar power output to the Renogy, but it does include a Pure Sine Wave AC inverter. Also lightweight due to its Lithium Ion battery. It is also more expensive and I don't know about the quality of the build or how well Suaoki stands by their product.

Based on reviews I have seen, there are some build quality issues, which are expected. The warranty (1-year) is half as long as the Renogy's.


Goal Zero Yeti 400 Portable Power Station, 400Wh Battery Powered Generator Alternative with 12V, AC and USB Outputs

Goal Zero Yeti

This is a neat device and looks good from a power storage standpoint. But it uses a lead acid battery and I'm not sold on that idea for a small, portable generator. At almost 30 pounds, I want to read reviews praising the company for such a long-lived battery and crazy power output, but those reviews are really not there.

The pure sine wave inverter is a big plus. The warranty is only 1 year and it is more expensive than the Renogy.







Jackery Portable Power Station Generator Explorer 440, 440Wh Solar Generator Lithium Backup Power Supply with 110V/300W (500W Peak) Pure Sine Wave AC Inverter for RV, Camping CPAP Fishing Emergency


Jackery portable Power Station

Jackery is a young company but they sell quality portable products and appear to be positioned to be a long-term, viable competitor in the portable power industry.

Their 440 Watt hour solar generator features lithium ion and a pure sine wave inverter. It is light, but almost 20% more expensive than the Renogy. It also features a 2-year warranty.

Also, missing is the ability to charge directly from a 12 volt system, as with the Renogy. However, the Jackery does allow solar charging in addition to 110 Volts AC.

Don't Forget Your Solar Panels!

Don't even bother trying to find a bigger bang for your buck when it comes to portable solar panels. Just head to Renogy:

Renogy Foldable Solar Suitcase Kit 100W Mono Without Charge Controller

Renogy Foldable Solar Suitcase Kit 100 W Without Charge Controller

This 100 Watt panel kit is capable of 500 watt hours per day. The cells are German made and the frame is aluminum. Monocrystalline is a little more expensive but this ensures better performance in low light conditions and excellent energy yield.

This is the perfect complement to your portable generator and it truly affords unlimited power capability!

Product dimensions:

69.1 x 6.1 x 50.5 inches

12.8 pounds

30 Amp BUILT-IN 4-stage solar charge controller

Negative ground charge controller for RV, boat, trailer compatibility

Renogy 100W Solar Suitcase in Action


For most applications, the Renogy Rugged Power Pack (Check current price) together with the Renogy 100 Watt Foldable Suitcase solar kit (Current price) are a potent combination of on-demand, portable, unlimited power.

They represent a best-in-class choice based on their build quality, materials used, price and warranty.

I understand that for some of you reading this, a pure sine wave inverter is a ‘must have' item. I might be inclined to agree, especially for extended trips away from the power grid.

My suggestion if this is the case would be the Jackery Portable Power Station Generator Explorer 440 paired with the Renogy solar panel suitcase kit.

Either way, you are buying quality and the promise of unlimited portable power for years to come.

  1. Hi Mike, wow, awesome reviews here! I had no idea that these type of generators even existed. I always presumed that to get solar power was a big investment in money and the reason why so many still don’t use it (I’m in the UK, so maybe we don’t think about it as much).
    But I can see how it is vital to have a back up when you live somewhere where the power goes so very often. In fact, none of us know what’s going to happen in the future so we should all have some kind of back up like this. It would certainly make me rest easier. Plus, it’s much more environmentally friendly I’m presuming?

    1. Hi Stefanie, the portable or ‘plug & play’ solar generator is emerging as the next big thing in solar power. Building a small scale solar power system is not difficult, but choosing compatible components, proper wire and connectors, tools etc, can be intimidating for the average person. The portable generator is a ‘done for you’ system, right out of the box. Even the battery is contained in the system. Add a solar panel and away you go. This product category will entice millions of people into the solar camp and is very exciting. Thanks for your comment. Mike

  2. Thanks on your marvelous posting! I certainly enjoyed reading it, you could be a great author. I will be sure to bookmark your blog and may come back later in life. I want to encourage that you continue your great job, have a nice morning!
