Introductory

I've had a few garden machines and battery-powered tools arrive at my place lately, but the Foursun LB01 its arrival surprised even me. This compact but incredibly powerful electric blower has once again confirmed that you shouldn't believe your eyes, turn it on before you judge. While the smaller turbo blowers in my previous tests were more suitable for dusting the workshop table, this machine is in a completely different league: according to the manufacturer, it will revolutionize garden cleaning, car cleaning, and even winter snow removal – and they're not lying!

The market is currently full of weak, “toy” category cordless blowers, but the Foursun LB01 Based on its technical specifications (stormy wind speed and brutal air flow), it is clearly aimed at more professional users. In this test, I will investigate whether the nearly 200 km/h air flow promised on paper is really enough against wet leaves and frozen snow, or is it just another loud noise?

This is a marketing ploy. Stay with me, because this test is going to really blow you away!

Industrial design and brutal accessories: This is what the Foursun LB01 looks like up close

When I took the Foursun LB01-, my first thought was that this machine does not want to be refined. Its design is functional and robust, although the material is simple ABS plastic at first glance, it feels extremely stable and solid. There are no unnecessary decorations on it, every part of it serves efficient work. The length of the device without a nozzle is 280 mm, but if you snap on the included extension tube, you already get a 660 mm “cannon”, with which you do not have to bend down during garden work.

The contents of the package are particularly generous, which is rare in this price range. The Foursun LB01 We get not one, but two 4.0 Ah, 21 volt lithium-ion batteries. These batteries have a serious weight, which indicates the capacity inside them. Their special feature is that they can be charged via a USB-C port (also), so we don't have to carry a huge, separate power supply with us; a regular phone charger or a larger power bank is enough in addition to the factory cable.

On the top of the device is the “control center”, which is a digital LCD display on which we can monitor the battery charge (in four segments) and the currently selected speed level from 1 to 5. The speed is controlled by an ergonomic, thumb-operated potentiometer (knob), which allows for precise switching. The list of accessories is completed by a comfortable shoulder strap that can be attached to the machine, so the 1,66 kg weight does not become tiring even after prolonged use. I note that the strap is almost unnecessary due to the low weight, but I do not regret that it was included in the box. The package also includes a decent-length blowpipe, which can be attached to the front of the machine with a bayonet lock solution, with a single click.

Brutal numbers – Foursun LB01 specifications

If we look at the technical data, the Foursun LB01 a true engineering feat, so much so that I couldn't believe what I was reading when I was browsing the specifications. Even less so when I held the machine in my hand, but that's my fault. The heart of the machine is an extremely high-torque, brushless ducted motor (turbine system), which is much more durable and efficient than traditional solutions. This motor is capable of 38,000 revolutions per minute (RPM), which is amazing performance for such a large handheld device.

The most important data that the Foursun LB01 boasts:

• Maximum wind speed: 55 m/s, which translates to approximately 198 km/h. This is a hurricane-force air current!

• Air transport: 606 m³/h, which means it can move a huge mass of air, not just blow in a thin jet.

• Maximum air pressure: 1500g of blowing force, which is enough to push away even stuck, wet leaves or heavier pebbles.

• Battery system: 48V (21V max) 4.0 Ah Lithium-ion packs, built from the most efficient 18650 cells.

• Operating hours: At level 1 up to 120 minutes It is capable of continuous operation, but can withstand creasing even at the highest setting for 15-20 minute cleaning cycles.

The machine also has intelligent control: it has built-in protection against overheating, overcurrent and short circuit. This is especially important in the highest level, 5, where the machine pushes the limits of physics. The digital display is not just for decoration, but also provides real-time feedback on the machine's status, so you will never be surprised by a low battery.

Field Experiences: When the Foursun LB01 Goes Wild

First of all, I must state: Foursun LB01 you will grin while using it, I grinned too. Not only because it blows everything away on the street, but also because I didn't turn it on in the office. I can't imagine what would have happened… When I first pushed the cocoa on it in the garage, it blew my tools off the table on speed 5. Damn, that's no joke! But at first glance I seriously thought this machine was going to be a joke. There's nothing in the housing except for the slightly longer than average motor and a plastic fan blade. Oh, and if you snap the battery in, that's it. But that's all. There's the display and the dial on the top, but that's it, and you think they've screwed your head over with this device. Until you turn it on, because then you realize you've seriously underestimated its capabilities!

During the garden test, the Foursun LB01 literally my garden. I had to go out into the woods to see the point of the test, because there wasn't much to blow away in the garden. I can definitely say that it can sweep away piles of leaves with such efficiency, as if we had an invisible broom in our hands. The 3rd and 4th settings are more than enough for most tasks. I also tried it to dry my car after washing: in 5-10 minutes, on the 4th setting, it blew the bodywork and rims completely drip-free, which is a huge help if someone cares about the cleanliness of their car. I also used it to dust my 10-inch wheeled scooters, it blew out the stuck mud from even the smallest gaps.

However, there are also some oddities. The 5th, or “turbo” setting, requires such brutal energy that it happened that the machine turned off after 20-30 seconds. Some kind of protection could be causing this (I realized in the meantime that the battery protection is the reason), I don’t dare to think about overheating, because such a large amount of air passes through the tube (which also cools the motor), due to which the chance of it heating up is very small. It is certain that if this happened, removing and replacing the battery helped. This is a bit annoying, but seeing the storm it produces in this mode, perhaps the protection is understandable. Maybe the machine is not protecting itself, but me… Fortunately, the 4th setting is also much stronger than most of its competitors on the market, and I did not experience the strange shutdown at this setting either. The battery operating time for me, with intensive use at settings 3 and 4, lasted about 15-20 minutes on a single charge. Since we get two batteries in the package, we can easily complete a good half-hour of continuous "storming", which is more than enough to clean an average yard or two cars.

What do I regret after the test? That I didn't buy this machine sooner! I shoveled a lot of snow this winter, but I'm sure that the Foursun LB01I would have blown the 10-15 cm of snow off the sidewalk with ease. This reminds me of this, I read in the user manual that in cold weather (below 0°C) it is worth “running” the machine for 2-3 minutes at a lower speed to warm it up, and of course keep the batteries at room temperature until use, because they tend to give up sooner in the cold. Overall, the power of the machine is impressive, and its usability is versatile, whether it is cleaning the workshop or gardening.

Conclusion: Is the Foursun LB01 worth the price?

A Foursun LB01 is clearly one of the best value for money choices on the market today if you are looking for a truly POWERFUL, portable blower. It is not a cheap plastic toy (although it may seem like one at first), but a well-thought-out, brutally motorized device that, with its two batteries and extensive accessory list, far exceeds expectations. Although speed 5 can sometimes be too demanding on the system, the remaining four speeds of the machine also offer more power than the average household would ever need.

I especially recommend it to those who are tired of sweeping the terrace, or who want to dry their car quickly and without scratches, and who don't want to shovel snow in the winter. Due to its compact size and shoulder strap, it is ideal for women or the elderly, because they don't have to drag heavy gasoline machines. The Foursun LB01 proved that in the age of brushless technology and modern batteries, there is no longer a need to compromise between portability and raw power. BRUTAL!
