Titan Solar Generator vs Inergy Flex

Short on Time? Here’s The Article Summary

The article compares the Titan Solar Generator and the Inergy Flex, two portable power stations designed to provide clean, renewable energy. The comparison covers technical specifications, power outlets, capacity, and charging times. The Titan Solar Generator offers 2,000 Watt-hours capacity, six 110-120V AC outlets, and a charge time of approximately 4 hours from 0% to 100%. In comparison, the Inergy Flex provides 1,069 Watt-hours capacity, six AC outlets, and a similar charge time of around 3 ½ hours.

Power Outlets

Titan Solar Generator vs Inergy Flex

The Titan Solar Generator and the Inergy Flex both have a wide selection of power outlets that can be used to power a number of different devices. 

The Titan Generator has 6 110-120V AC power outlets to power large appliances like fridges or microwaves. Each set of 3 110V AC power outlets comes with its own 15A fuse, so you can draw consistent power without fear of anything tripping.

The Titan has 6 standard USB ports and an additional 2 USB-C ports. Above those are 4 12V DC carports which make it a great option for keeping all your devices charged on a camping trip.

In addition to the impressive array of standard power outlets, the Titan has a 30A RV port that can be plugged directly into a campervan or mobile home. Because of the Titan’s high power output, it can easily keep an RV and all its appliances running.

The Inergy Flex has the same 6 110V AC power outlets as the Titan, but all outlets are run on the same fuse. In combination with the diminished power output, this significantly limits the number of devices you can power at once.

The Flex has 2 standard USB and 2 USB-C power outlets, as well as 2 12V DC car charging ports. Although this is fewer than the amount on the Titan, it’s more than enough for most people’s needs.

When it comes to the number and capability of power outlets, the Titan Solar Generator is leagues ahead of its competition. However, the Flex has 2 5.5mm DC outlets that are a great option for LED lamps for camping.


The capacity of a portable generator will determine how many devices your generator can power, and for how long.

The Titan Solar Generator stays true to its name, providing a whopping 2,000 Watt-hours (Wh). This is one of the biggest batteries available on the market and it can keep appliances going for hours at a time without needing to be recharged.

2,000Wh is enough to power a portable fridge for over 40 hours even if you left the door open.

The Inergy Flex has just over half the capacity of the Titan, at 1,069Wh. This might seem minuscule by comparison, but it’s still enough to power the same fridge for half a day.

Both the Titan and the Inergy Flex are completely expandable, meaning you can keep adding battery packs to increase the capacity of the generator.

The Titan Solar Generator is miles ahead of the Inergy Flex in terms of battery capacity. With more than twice the storage, it can power more devices for longer which makes it an ideal option for a backup power source.


The time it takes to fully charge a portable power station is arguably just as important as its capacity. You don’t want to be caught off guard by a power outage only to find that your battery is only at 50% after a day of charging. 

The Titan Solar Generator’s charge time is surprisingly fast considering its mammoth energy capacity. Plugged directly into an AC wall outlet, the battery will go from 0% to 100% in a little over 4 hours.

Combining two or more Titan batteries gives users the opportunity to charge the device with a second AC wall outlet. This means that you can double the capacity of your generator without adding to the charge time significantly.

The Inergy Flex has a smaller inverter, meaning it cannot draw the same amount of power when charging. This means that, despite the fact it is around half the size of the Titan, it takes around the same time (3 ½ hours) to charge.

In this area again, the Titan comes out on top.

Inergy Flex or Titan Solar Generator

Although both devices are marketed as portable power stations, they each fill a different niche. In this section, we’ll briefly go over the features, pros, and cons of each device.

Inergy Flex

The Inergy Flex was built to be a durable, portable power station. Its compact design and lightweight build make it easy to pack into the back of your van for those spur-of-the-moment camping trips.

The Flex has a modular design, allowing users to add as many as 96 additional power banks. This means that the total possible capacity of the generator is over 100,000Wh - although at that point it would weigh over 2,000 pounds.

Solar panels for the Flex are rated at 300W, which would fully charge the battery in 4 hours in ideal conditions. In real-world weather conditions though, 5-6 hours is more realistic.

The Flex MPPT Supercharger is an optional extra which increases the solar charge current threefold. It also lets users charge the generator through solar, USB, car ports, and AC wall outlets simultaneously.

Although it’s smaller and less powerful than the Titan Generator, the Flex is still a great choice for people looking to get off the grid. It’s quite a bit cheaper than its competitor and still capable of keeping your lights on and cell phones charged for hours.


  •  Lightweight and portable.
  • Completely silent and emission-free.
  • Highly affordable.


  • Limited battery capacity.
  • Fewer power outlets.

Titan Solar Generator

As the name implies, the Titan Generator is a giant of a power station. Not only is it one of the largest battery banks in terms of capacity, but it also weighs as much as a small sofa.

While this might be pushing the definition of “portable”  a bit, the features of the Titan more than make up for its weight.

Like most newer solar generators, the Titan comes with built-in MPPT charge controllers. However, where other commercial solar generators have only one charge controller, the Titan has two that work concurrently.

This means that not only is it one of the biggest batteries on the market, it’s also one of the most efficient. 

The Titan is also highly durable. The manufacturers give the battery lifespan a 2,000 cycle rating. This means it can be fully discharged 2,000 times before the capacity drops below 20%. Even with heavy usage, this will take around 10 years.

The price tag could scare some people away, as even the best price for Titan Solar Generators is well over $2,000.

Because of the price and weight, the Titan isn’t a great choice for those constantly on the move. The ideal user is someone who lives in a disaster-prone area where continuous power supply isn’t always guaranteed.


  • Huge power capacity.
  • Long lifespan.
  • Rapid charge time.


  • Very expensive.
  • More complicated than other portable power stations.

Titan and Inergy Flex FAQs

Is Titan better than Inergy Flex? 

Unfortunately, there’s no easy answer to this. Each power station fills a different need, so the best portable generator for you depends on what you want to use it for.

Because the Flex is so lightweight and inexpensive, it’s a great choice for those who love spending time outdoors. It’s easy to throw in the back of your car before heading out for a weekend in nature.

The Titan is bigger and more expensive, so it works best in a stationary set up. If you want to power your home with clean, renewable energy, it’s a fantastic all-in-one solution.

What is the average price of a solar power station?

How much a solar generator costs will depend mostly on the capacity, as well as other features like the number of power outlets, surge protection, and inverters.

An average solar power station can cost anywhere between $800 and $1,200, but there are plenty of options both more and less expensive.
