Chamberlain B750 Garage Door Opener Review of 2021

Are you considering purchasing the Chamberlain B750 garage door opener?

As far as garage door openers go, the Chamberlain 3/4 HP equivalent ultra quiet belt drive smart garage door opener B750 is certainly a good choice.

However, the Chamberlain B series also offers a host of other options that are just as good and in some cases, even better than the Chamberlain B750 garage door opener.

Today we are going to review the best garage door openers in the Chamberlain B series and see which one is the most suitable for you.

How Did We Decide Which Chamberlain Garage Door Opener Is the Best?

Chamberlain is known for providing high-quality garage door openers that deliver superior performance. While the best 4 we review have a number of similar features, there are also some distinct differences that set them apart from each other.

With that in mind, realize that we did not order the four openers below from best to worst. Instead, we noted what we think is the best reason for buying each model and noted that appropriately. We chose these based on the availability of the following features.


While the security isn’t likely your main reason for owning one (assuming the ease of opening and closing the door remotely is the chief reason), it’s still a valid point to consider. Just how secure is the opener, especially one with Wi-Fi or similar capability that has the potential to be hacked?

Strength and Durability

You don’t want to replace your smart garage door opener every year – or every decade, for that matter – so you want one that will stand the tests of time and frequent usage. We looked for openers that did just that.

Lift Capacity

We can’t know how big and how heavy your garage door is, but we can provide the lift capacity data so you can determine if a given opener will be able to handle the door you already have or the one you plan to purchase soon.

Backup Battery

It’s relatively rare these days (in most areas) that the power goes out, but when it does, you want to have the reserve power that a battery provides. We favored the models that have a backup battery but didn’t consider this to be a deal-breaker if it didn’t.

Other Accessories

Sometimes it’s the little extras that can sway you one way or another. We considered these extras as decent-sized bonuses when making our picks.

#1: Chamberlain B750 3/4 HP Ultra Quiet Belt Drive Garage Door Opener (Best for Budget)

The Chamberlain B750 3/4 hp equivalent ultra quiet belt drive smart garage door opener is a powerful unit. It has a lift force equivalent to 3/4 hp and is capable of lifting garage doors that are 7 feet high and weigh around 370 pounds. This should cover most garage doors. In most cases, if you have a door that is larger than this, you can get an extension kit to handle it.

Weighing only 31.9 pounds, the B750 is lighter than most other products offered by Chamberlain. It measures 26.7 x 13 x 8 inches and has a control range of 1,500 ft. The device can be controlled remotely using a smartphone and a Wi Fi connection. It operates using a steel reinforced belt drive composed of the highest grade steel.

Besides the opener, you will also receive the following items.

  • Remote Control x2
  • A wireless keypad
  • A dual-function wall control
  • Built in MyQ technology – Get Alerts anytime from anywhere.

Additional features of the B750 garage door opener include highly effective safety sensors and automatic lights. The safety and security sensor can help ensure it doesn’t end up closing while someone is passing through, thereby ensuring the safety of your family.

It comes with a 5-year warranty on parts. There is also a 1-year warranty for the accessories that come with the garage door kit and a lifetime warranty on the motor and belt.

Overall, its ultra-quiet, belt drive smart garage door opener fares well in terms of performance, functionality, and durability. The only thing that counts against this opener is the lack of additional security.

There is also no backup battery available. If that’s something you are concerned about, then we suggest you consider one of the other 3 on our list or a model from LiftMaster.

#2: Chamberlain B550 Smart Garage Door Opener (Best for Value)

The Chamberlain B550 encompasses the best security features that Chamberlain has to offer, putting it a notch above the rest in that category.

It has the equivalent lift capacity of 1/2 HP, which delivers the highest lifting capacity in this particular category and allows the Chamberlain B550 belt drive smart garage door opener to deliver a robust performance despite extreme conditions.

The unit is a little on the heavy side and weighs around 35 lbs. Like other Chamberlain smart openers on our list, this one also comes with 2 remotes, a wireless keypad, motion sensors, and a fully-functional wall control panel.

Its newest feature is the enhanced Triband technology. This provides you with a superior range, less interference, and better overall performance.

Its security bundle comprises a number of security features. These include an Automatic lock capable of securing your garage door each time it is closed, and Chamberlain’s premium encryption technology that is designed to prevent hacking and unauthorized access. Security features such as these are especially useful if you have an attached garage. If someone could gain access to your garage, they could then just as easily get into your house.

The new unit also has built-in Wi-Fi connectivity, and the ISP can be monitored and controlled using a smartphone and the built-in MyQ technology.

It is ultra-quiet, and the DC belt drive opener is designed to eliminate vibrations making it ideal for attached garages. It’s also easy to install.

There is also a backup battery, ensuring it remains operational even during tough weather conditions that lead to a power outage.

#3: Chamberlain B503C Quiet Garage Door Opener (Best Lift Power System)

The Chamberlain B503C is an ultra-quiet unit that is very easy to install and operate. It is ideal for an attached garage. It is constructed with high-grade materials that offer durable and long-lasting performance. It has a steel-reinforced belt drive that ensures smooth operation.

The device ranks high in terms of security too and is equipped with posilock anti-theft protection technology along with Security+2.0 that ensures high-end encryption and prevents unauthorized personnel from breaking into your home.

The unit is powered using Chamberlain’s MED plus Lift Power System. For some of their opener models, Chamberlain simply assigns a plus lift power system category instead of specifying the actual horsepower available. This model has the equivalent power of a 1/2 HP unit.

The device also comes with 2 remote controls, motion sensors, wall control, and built-in Wi Fi connectivity. It has a remote range of up to 1,500 ft. Unfortunately, there is no backup battery.

If you are looking for one that offers strength, reliability, and easy installation, then you can’t go wrong with the Chamberlain B503C.

#4: Chamberlain B970 Belt Drive Smart Garage Door Opener

Another impressive offering in the Chamberlain B series is known for its quiet, reliable, and smooth performance.

Like the B750, this one also has built-in Wi Fi capabilities and comes with wall-control, 2 remotes, and a wireless keypad. It has a strong motor with a lift capacity of 1 1/4 HP, making it the most powerful of any opener on our list. This doesn’t just allow it to lift heavier loads. It also adds to the durability of the unit, so you can expect it to last longer than many others.

It has an ultra quiet belt drive, motion sensors, and a control range of 1,500 feet. The unit also comes with a backup battery. This is a major perk as it ensures the device remains functional in the event of a power outage. You won’t be forced to go out into the bad weather to manually open your garage door.

The Chamberlain B970 also performs well in terms of security. It utilizes over a billion secure code encryptions and has a Posi-lock anti-theft system designed to prevent anyone from gaining unauthorized access to your home. Only the most sophisticated hacker could break into this system. But seriously, why would they try?

You can also control the unit using your smartphone. All you have to do is install the myQ app and gain remote access. The warranty for this unit is the same as the B750.

On the whole, the Chamberlain B970 delivers great value. A few things that work against this unit are that it is not all that easy to install (see the B970 owners manual), and given the relatively high price level, if you are looking for a cost-effective opener, then this may not be the best option.
