Ddodocool Car Diffuser

Operation principle

An ultrasonic oil diffuser, dodocool uses ultrasonic vibrations to break the essential oil down into fine particles. The particles are then mixed with steam and dispersed into the air, providing both a humidifying and aromatizing effect.

Usage

  • Add water below the max line.
  • Add 2-3 drops of water-soluble essential oil.
  • Connect the diffuser to your car’s cigarette lighter port.
  • Press the mist button to start the operation.

Overview

Dodocool car diffuser is a nice option if you wish to enjoy a pleasant fragrance in your car hours long. Thanks to its 70ml high-capacity water tank, this diffuser is capable of providing up to 3-5 hours of continuous mist.

In addition, this oil diffuser has 7 inbuilt LED colors, which may allow you to further enhance the ambiance in your car.

While this essential oil diffuser is bulkier than the other models on the list, it still is compact enough to be conveniently used in a vehicle. Namely, you should be able to put it into a cup holder just fine. The size shouldn’t interfere with shifting as well.

Pros:

  • Both humidifiers and aromatizes.
  • Large 70ml water reservoir.
  • Inbuilt 7 LED colors.

Cons:

  • Refilling can be messy.
  • A bit bulky.

FeatherFine Car Humidifier & Diffuser

Operation principle

Works basically in the same way as dodocool car diffuser.

Usage

  • Fill the diffuser with water.
  • Add a few drops of water-soluble essential oil.
  • Plug the device into your car’s cigarette lighter port.
  • Swivel the diffuser in the direction you want to spray.
  • Power the diffuser on.

Overview

FeatherFine car diffuser is quite an interesting model, both in terms of its design and the features it has to offer.

First of all, this car oil diffuser can disperse mist directionally. It has a rigid swiveling neck that can be rotated in 360 degrees. This would allow you to get a more focused stream of fragrance into the car.

In addition, FeatherFine car diffuser has 2 integrated USB ports that can be used for mobile phone charging or whatnot. Essentially, this diffuser has an inbuilt USB hub in it.

In terms of water capacity, FeatherFine oil diffuser is pretty nice. It can hold up to 50ml of water. Overall, it can produce 20-45ml of moisture per hour, giving you an about 2-hour runtime.

Pros:

  • Can disperse mist directionally.
  • Aromatizes and humidifies.
  • Has 2 integrated USD ports.

Cons:

  • Possibly messy when refilling.
  • You’d need to be careful when adjusting the neck not to spill water.

InnoGear USB Aromatherapy Essential Oil Diffuser

Operation principle

InnoGear USB essential oil diffuser is yet another ultrasonic diffuser on the list. It operates in the same way as the two previous diffusers: that is, it breaks down the oil into fine particles, mixes it with steam, and disperses in the environment.

Usage

  • Fill the device with water.
  • Add a couple drops of water-soluble essential oil.
  • Plug the diffuser into a USB port. Alternatively, use a 5V 1A car adapter.
  • Power the diffuser on and choose the desired mist mode.

Overview

InnoGear is very similar to the dodocool diffuser we reviewed in the very beginning, but there are some important differences that set them far apart.

One similar thing in the two diffusers is water capacity. Both have a 70ml water reservoir, so they both should have a very similar runtime. Likewise, the sizes of the two diffusers are very similar.

And yeah, both diffusers have 7 inbuilt LED light colors. But the similarities end here.

The first difference in this oil diffuser is that it has 2 mist modes – continuous and intermittent. The latter mode allows the diffuser to be a bit more sparing when diffusing oil.

The second difference is that this oil diffuser is powered via USB. What this means is that you could use the InnoGear diffuser not only in your car but also at home.

The not so good thing about this is that you won’t be able to use this diffuser in your car out of the box, unless you have a USB port in the car. Otherwise, you would need to get a cigarette lighter adapter.

Nonetheless, given that this diffuser’s use isn’t limited to just your car, we think that it is a great buy.

Pros:

  • Powered by USB.
  • Large 70ml water reservoir.
  • Aromatizes and humidifies.
  • 2 mist intensity modes.
  • 7 LED color options.

Cons:

  • No cigarette lighter adapter included.
  • Could be messy when refilling.

AromaAllure Essential Oil Diffuser

Operation principle

AromaAllure oil diffuser belongs to the class of so-called evaporative oil diffusers. The main components in this diffuser are the fan and the filter. The oil is dripped onto the filter and then blown out into the environment by the fan.

No heat or water is used in AromaAllure diffuser.

Usage

  • Add a few drops of essential oil on the fragrance pad.
  • Place the pad into the diffuser.
  • If you will be powering the device via USB, plug it into a USB port. Use an AAA battery otherwise.
  • Power up the diffuser.

Overview

When it comes to quick fragrance delivery, probably no diffuser on the list can compare with AromaAllure’s solution. As we already said, this essential oil diffuser employs a fan to assist with the diffusion, which is the thing that allows it to deliver fragrance a bit quicker.

And what’s even better is that this diffuser doesn’t require water for operation.

On the other hand, the fan is going to obviously make noise, and if you get easily distracted while you drive, you may dislike this oil diffuser.

What is also good in this diffuser is that it can run either via a USB port or an AAA battery, whichever is more convenient for you at the moment. And this also means that you can use this diffuser at your home and anywhere else outside the car.

The quick oil dispersion has a downside as well: this thing is only capable of running up to 30 minutes. This is why we think that this diffuser is more suitable for situations when you need a quick stream of freshness in your car.

Pros:

  • Doesn’t run on water.
  • Assists diffusion with a fan.
  • Battery- or USB-powered.
  • Employs a fan to spread the fragrance.

Cons:

  • The fan’s sound may be annoying to you.
  • Runs for only 30 minutes.
  • Doesn’t come with a cigarette lighter adapter.

RoyAroma 30mm Car Aromatherapy Essential Oil Diffuser

Operation principle

RoyArome oil diffuser basically is a locket with a fragrance pad in it. The essential oil is dripped onto the fragrance pad. Then, the oil’s elements are spread solely via diffusion without the use of fans, water, or heat.

To increase the efficacy of this diffuser, you could clip it onto an air vent in your vehicle. The airflow is going to greatly improve the diffusion, basically turning this device into a fan-assisted diffuser.

Usage

  • Apply a few drops of essential oil onto the fragrance pad.
  • Put the fragrance pad into the locket.
  • Clip the locket anywhere in your car, preferably to an air conditioning vent.

Overview

Thanks to its simple design, RoyAroma oil diffuser has plenty of advantages.

First of all, it requires absolutely no power for operation, meaning that you could use it basically anywhere, be it your car, home, office, and even a camping tent if. Likewise, this diffuser needs no water, which basically makes it mess-free.

Secondly, this essential oil diffuser produces no sound, so it is a good option for people who get easily distracted while driving.

What we also like in this set is that it comes with 2 diffuser lockers and 12 fragrance pads. This means that you could aromatize air in two locations, as well as quickly swap fragrances without washing the pads.

With all that being said, this essential oil diffuser isn’t going to be too quick when diffusing oils. With no internal mechanisms that would assist it, it basically relies on plain diffusion to spread the fragrance. And this can take quite some time.

But fortunately, there are a couple of workarounds about this issue, like clipping the diffuser to a car vent or placing it near a heat source.

Pros:

  • Very compact.
  • Completely quiet.
  • Requires no water or electric power.
  • 2 lockets and 12 fragrance pads included.

Cons:

  • Doesn’t spread the oil too efficiently.

Balai USB Essential Oil Diffuser

Operation principle

Balai USB essential oil diffuser appears to rely on heat to diffuse the oil. This method of diffusing is similar to fan diffusing, with the difference being that heat diffusers use heat instead of fans and thus don’t produce any sound.

However, the heat produced by this diffuser may alter the composition of the essential oil, so you would need to be careful when choosing oil.

Usage

  • Take the fragrance pad out of the diffuser.
  • Drop about 4-5 drops of essential oil on the fragrance pad.
  • Place the pad back in its place.
  • Attach the top cover to the diffuser’s body and slide it until hearing a click.
  • Power the diffuser on.

Overview

Like RoyArome diffuser, Balai essential oil diffuser also operates noiselessly. However, as we mentioned above, the operation principle of this device is a bit different.

This diffuser employs heat, and to produce that heat, it requires power. And it gets power either via USB or an optional rechargeable battery. So while this diffuser can be used pretty much anywhere, you will have to think about providing it with power.

Still, this diffuser doesn’t require any water, meaning that you won’t have to deal with any water-associated issues.

Another nice thing about this diffuser is the up to 10-hour runtime. While this diffuser won’t be providing you with an immediate flow of fragrance, it should be capable of maintaining a pleasant environment for a long time.

And lastly, this diffuser is quite compact, so it won’t be taking too much room in your car.

Pros:

  • Runs on USB or rechargeable battery power.
  • Up to 10 hours of runtime.
  • Waterless operation.
  • Runs noiseless.

Cons:

  • The heat may alter the composition of the oil.
  • Doesn’t come with a cigarette lighter adapter.
