A compact, lightweight, and powerful rechargeable blower

Kaedia “Mobile Jet Turbine KDR-BL1 (6,988 yen).” It features a compact body with a built-in high-power brushless motor and battery.

Kaedia’s products are the kind that make many motorcyclists think, “Ah, this is exactly what I wanted!”I personally use the "Smart Battery Charger KDR-B12," which allows me to charge my motorcycle battery using a portable power bank, and I find it extremely useful.<\n

The product I’m introducing today is Kaedia’s "Mobile Jet Turbine KDR-BL1," a mobile blower that has been gaining a lot of attention lately.Thanks to advancements in batteries and motors, devices like this have become both compact and powerful. The KDR-BL1 is extremely compact, measuring 146mm in length, 96mm in width, and 40mm in thickness, and it’s lightweight at just 291g.

It features three adjustable airflow settings and a powerful 7.4V battery system powered by two 3.7V cells. With a capacity of 3000mAh, it can operate continuously for about 90 minutes on Mode 1 (Low).Two types of nozzles—round and flat—are included, allowing you to adjust the coverage area and pressure according to your needs. These nozzles use a magnetic attachment system, making them easy to attach and remove.

A blower really comes in handy when washing your motorcycle. It’s particularly effective at blowing away water that has accumulated in hard-to-reach areas like around the engine or in the hex socket bolts commonly used on the bodywork. Blowing air on these areas also helps prevent rust.

Also, when parking outdoors, moisture can still adhere to the body even if you use a cover on rainy days. In such cases, a blower allows you to quickly blow it away. Furthermore, if dust or sand sticks to the bike, using the blower first can help prevent scratches on the paintwork.

It’s slightly smaller than a 540ml plastic bottle, making it compact enough to carry in your pocket.

In addition to the main unit, it comes with two types of nozzles (round and flat) and a charging cable.

Powered by a brushless motor with a maximum speed of 130,000 rpm, the fan—which resembles an aircraft engine—generates a powerful airflow.

The nozzle is attached via magnets and features positioning pins.

The round nozzle generates a more powerful airflow by narrowing the air outlet.

The flat nozzle has less airflow but is suitable for working on large surfaces.

The flat nozzle can also be mounted vertically. It can be used for different applications depending on the task.

It feels great to blow away water droplets with the air blower!

Now, let’s actually try using the KDR-BL1. Mode 1, the weakest setting, is quiet and feels only slightly stronger than a full breath. Switching to the intermediate Mode 2 makes the operating noise a bit louder, and you can feel a slight recoil pushing the unit back. It feels about like a small hair dryer.

Then, when you switch to the strongest Mode 3, the operating noise increases further, and a surprisingly powerful stream of air blasts out from the compact body. If you’re not careful, the recoil could almost knock it out of your hands—and with this much airflow, it should be able to blow away most water droplets and dust.

When I direct the airflow from Mode 3 onto my arm, as you can see, it creates a deep indentation in my skin. If you’re not careful, it has enough force to blow things around you away.

After washing the car, I first try air-drying the wet gas tank using Mode 1.Since the painted surface is naturally somewhat water-repellent, the water droplets roll right off. Switching to Mode 2 naturally increases the speed, but be careful—depending on how you aim it, water droplets can scatter all over the place. Mode 3 is even stronger; if you don’t blow from above, the water droplets will actually climb up the side of the tank.

Next, the engine area. There are many spots a cloth can’t reach, making this an area where a blower is highly efficient. Here, I mainly used Mode 3 and fully enjoyed the exhilarating sensation of “powerfully blowing water droplets away.” This is where the blower truly shines, and it’s likely ideal for parts like the fins of an air-cooled engine.

Mode 2 is sufficient for blowing water droplets off the plastic body parts. The hex socket bolts securing the body panels tend to collect water, but the blower is perfect for removing water droplets from these areas.It seems like this could effectively prevent rust from forming. However, when using Mode 3, water droplets sometimes blew back inside, so it might be best to switch modes depending on the location.

Trying it out on the tank after washing the car. Water droplets don’t blow away easily unless you use Mode 2 or higher.

In Mode 3, the water droplets fly off nicely. Since the spray spreads 360 degrees when aimed straight, it’s best to aim it as if you’re letting it fall from top to bottom.

Flat nozzles are also effective for large surfaces. However, since the power is reduced, you should use them in combination with round nozzles.

There are areas around the engine where it’s difficult to reach with a cloth, so this is where the blower really shines.

When blowing in Mode 3, water droplets are removed almost magically. It’s best to be mindful of how you aim the blower so that the water droplets are directed outward.

Try using it on plastic parts as well. Just a light touch is enough to make the water droplets roll right off.

Water droplets are easily removed from resin parts even on Mode 2. If the pressure is too strong, water might seep inside through the seams.

The hex head bolt area is prone to water retention. Water can accumulate there after rainy weather, making it susceptible to rust.

Just a quick blast in Mode 3 was enough to blow away the water that had accumulated around the bolt holes and the seating surface.

Additionally, for parts like the windshield—which can easily get scratched if wiped with a rag—it’s best to blow away the dust with the blower first and then wipe with a soft cloth. Blowing air into hard-to-reach areas around the cockpit should also help prevent rust and deterioration.You’ll also appreciate the blower’s usefulness in gaps in the fairing and around the rear suspension.

There are two types of nozzles: the round nozzle with strong airflow is efficient for hard-to-reach areas, while the flat nozzle is best for finishing flat surfaces. Also, while this may depend on my specific environment (surrounded by buildings on all sides), Mode 3 is fairly loud, so you might need to be a bit careful about when you use it.

I used it this time to blow away water droplets after washing my car, but it can also be used to start a campfire or dry moisture on a tent, so it should come in handy for camping trips as well. Since it’s an item with a wide range of uses, having one on hand will surely prove useful in various situations.

Wiping the screen with a cloth can cause scratches, so it’s recommended to use the blower first.

Moisture tends to linger around the cockpit, so it’s a good idea to use the blower to remove as much of it as possible.

It’s also handy for starting a campfire, but in that case, use Mode 1. It’s also useful for blowing water droplets off tents and tarps.

How to Use and Details

The charging port is USB-Type-C, and it takes about 3 hours to fully charge. It cannot be used while charging.

Next to the USB charging port is an indicator that shows the remaining battery level.

The power switch is located on the back of the grip, with a mode indicator above it. It starts up in Mode 3.

A start/stop button is located on the front of the grip. In modes 1 and 2, the device activates with a single press; in mode 3, it operates only while the button is held down.

When the unit is powered on, pressing the power switch once switches it to Mode 2.

Pressing the power switch once more from Mode 2 switches to Mode 1.
