What is the visible difference we usually notice at first glance? Obviously, the size!

Flame Boss 400 comes with a compact design. Its overall dimension is 19 × 12 × 6 cm

Contradictorily, Flame Boss 500 is slightly larger than 400.

The total dimension of the product is 30 × 20 × 10 cm. This makes Flame Boss 400 more portable than the 500.

  • Weight

Flame Boss 400 weighs around 0.47 kg, whereas the upgraded unit weighs 1 kg 70 g. Again, lightweight smoker controllers are more portable than heavier ones.

But how will it benefit you? Suppose you have only one smoker controller and need to use it for several grills. This gives you the convenience of carrying from one area to another effortlessly.

  • Design

Though the construction of Flame Boss 400 and Flame Boss 500 is almost similar, they are slightly different. The overall design of Flame Boss 400 appears a little more attractive.

In opposition, Flame Boss 500 comes with an innovative design. It has a solid display and works with Wi-Fi technology to control the unit easily.

  • Control Panel

Here comes the most demanding difference. Unfortunately, Flame Boss 400 doesn’t come with a display. Controlling the smoker requires connecting the device with a smartphone application.

But Flame Boss 500 has a big LCD display with four lines. You don’t need to rely on the app always. All it requires is commanding the device using the built-in control panels.

It is simple to track up to three meat temperatures. You don’t need to use any Y-cables too. Different types of cooking stats will be visible on the screen.

All the essential cooking details give you a better overview of what is going on without checking your mobile application. It is undoubtedly a plus point for Flame Boss 500!

  • Blower Speed

 Flame Boss 400 comes with a 12.8 CFMs-rated blower. As long as the temperature doesn’t fluctuate rapidly, its fan speed is enough to control the pit temperature.

Contrarily, Flame Boss 500 has a 21 CFMs-rated blower. It comes in handy for massive charcoal grills and smokers. You can keep the pit temperature within ±10°F of your target.

  • Special Features

Flame Boss 400 works mainly through voice commands.

Download their official application from the PlayStore or App Store and connect it to your phone.

You need to use your smartphone microphone to instruct the device to adjust the temperature level.

On the other hand, Flame Boss 500 works with Google Home and Amazon Alexa devices.

Just connect your smoker controller with them and command using the voice command control.

Not even a finger needs to be lifted to figure out the cooking condition.

  • Adjustability

Here comes another turning point. Flexibility is a must when it comes to cooking. Flame Boss 500 provides better adjustability than Flame Boss 400.

You need to always rely on a smartphone for Flame Boss 400. After all, it doesn’t have any digital display. Always keeping the device connected to your phone is necessary.

If any Bluetooth or internet disconnection occurs, you will fail to track and adjust the cooking condition. But things are easier with Flame Boss 500. No need to always rely on the app!

Its digital display can give you enough information to know the cooking details. Hence, you can still adjust the temperature if there is no Bluetooth or internet connection.

  • Compatibility

You can’t use a single smoker controller for all devices. Flame Boss 400 is ideal for all-sized Kamado-style smokers, grills, and primo. Plus, you can use it for a few broils King and Vision classic grills.

On the other hand, Flame Boss 500 is best for offset-style larger charcoal grills, cabinets, drums, and egg and primo. However, its Steel version doesn’t work with a few Kamado-style smokers and grills.

  • Price

Not all of us have the same budget. But it is better to spend a little bit more money to get the best bang. Flame Boss 400 is an affordable option for Flame Boss 500.

The larger dimension and digital display panel increase the price of Flame Boss 500. But doesn’t it worth it for the additional valuable features you get? Surely does!

The price difference between these two units can be more than $100. But if you only prefer a basic smoker controller for occasional purposes, Flame Boss 400 won’t be the wrong choice.

Which Smoker Controller Is The Best For You?

Now, it’s time to decide the best option for you. If you want a lite smoker controller at a pocket-friendly price, Flame Boss 400 is a good choice. It is simple to use and offers effortless temperature control.
