If you've been caught unprepared for a power outage, we know how inconvenient it can be. And depending on the time of year, it can also be dangerous.

Power outages can happen for several reasons, mostly from major events like winter storms. One way to be prepared is to keep candles and torches handy in case the power goes out at night. But with a generator, you are able to use electrical items.

We're giving you everything you need to know about the OUPES Mega 5 portable backup generator. So, if you don't want to be caught unprepared, keep reading.

What Is a Portable Backup Generator?

A portable backup generator is a power source for tools and appliances when the power goes out that is easy to transport. Traditionally, they run on propane, diesel, or gasoline; however, alternative options like solar generators are available.

Each backup generator will have a couple of electrical outlets, allowing you to power more than one item at a time if needed. Because these generators run on fuel, they can be dangerous if used inside the house. Instead, this generator should be set up outside where it can safely operate.

Solar Portable Backup Generator

As mentioned, an alternative option to a fuel backup generator is a solar backup generator. These solar generators are a hybrid between an electric generator and a solar one. There are three ways you can charge a solar portable backup generator:

  • Plug into an outlet in your home
  • Use solar panels
  • Plug it into your vehicle

Not all portable solar generators are sold with solar panels, so you have to buy them separately or look for a bundle or kit.

What Is the OUPES Mega 5 Solar Generator?

The OUPES Mega 5 is revolutionizing solar generators. A powerful mobile power station, the OUPES Mega 5 can generate 5.04kWh at 4000 watts, making it an ideal option for almost any situation.

It's a portable solar generator with heavy-duty wheels that allow it to be easily moved. This new model has several more features, which we'll review in more detail here.

Scalable Capacity with an Expansion Battery

As a standalone unit, the Mega 5 has a 5.04kWh allowing you to run it for 2-3 days of emergency use. However, with an expansion battery, the OUPES Mega 5 can support a solar battery capacity of up to 10.08kWh. This could be enough solar battery storage to keep you running for 4-6 days of emergency use.
