Hyundai HYM40LI330P Review

The Hyundai HYM40LI330P is a cordless lawn mower powered by a Samsung lithium-ion battery with a capacity of 2.5Ah and a runtime of up to 30 minutes. It includes a 33cm deck, a 30 litre grass collection box, three cutting heights of 20mm, 40mm, and 60mm, and is only 11.4kg in weight. Hyundai’s HYM40LI330P comes with a mulching plug and is backed by a three-year warranty.

When it comes to cordless mowers, you’ll typically encounter a big machine with a big cutting width, and that may be the case with the huge version of this model, the Hyundai HYM40LI380P. However, if you want a more compact mower for a smaller lawn, the Hyundai HYM40LI330P, its younger sibling, might be the answer. Despite the fact that this model has a slightly lower cutting width of 33cm, it is nevertheless packed with features that will make it a welcome addition to your garden tool collection.

It contains a super-strong Samsung lithium-ion battery that will give you all the power you need to finish the work in one go. However, you will also benefit from a 40V motor, which is ideal for grass maintenance.

You still get a decent grass collection bag for a little mower, which is just one of the characteristics that make this mower easy to use.

While the larger HYM40LI380P has five cutting heights, this smaller model just has three, which is more than enough if you’re decided on how long you want your grass to be — in many cases, less is more. And this is a cordless mower that, while little, packs a punch.

Batteries & Power System

We’ve already mentioned that this mower is powered by a powerful Samsung battery, so knowing that you’ll be receiving this company’s power technology combined with the innovation of the big Hyundai gives you confidence that this mower will run like a dream.

The 2.5Ah battery is designed to provide up to 30 minutes of continuous running time, making it ideal for smaller lawns — you’ll get the job done in one charge. In addition, unlike some other models that require two batteries, this one only requires one, resulting in less energy wasted during charging and a far simpler design.

Even if you opt to mow in the wee hours of the morning, the motor, while relatively decent at 40V, offers a super-quiet operation, so you won’t be making a racket.

Charger for batteries

One of the most remarkable features of the charger that comes with this is the reasonable pace with which it charges the battery. You can go from empty to fully charged in just 80 minutes, which means you won’t have to wait long to get to work. You might think that 80 minutes is a long time to wait for a full charge, but this mower comes with a quick charger that cuts the charge time in half to just 30 minutes!

Furthermore, the battery and charger are both extremely durable, having been engineered to last for 1000 or more charges – imagine how many times you could mow the lawn with that!

In-Detail Features


The 330mm steel blade on the Hyundai HYM40LI330P is great for durability and a cleaner cut. Steel blades may be sharpened or replaced by anyone with simple DIY abilities.

This blade size is ideal for smaller grassed areas and even medium-sized lawns.

Height Modification

The Hyundai HYM40LI330P has fewer height possibilities than the larger version of this item, but that doesn’t mean it’s not adaptable. You have three options here, ranging from 40mm to 60mm, so it’s a good choice if you don’t need to drastically change the length of the grass at different times of the year or for different areas of the garden.

You may modify the height by sliding the axle into the height slot you wish to use, and then you’re ready to go – so it’s not just precise, but also simple to alter. Although I prefer a height adjustment lever situated on the top of the deck to this form of height adjustment (mower must be turned over), this way appeared to function without issue. Before turning the mower over to adjust the height, be sure the battery and the safety key are both removed.

Diameter of the Cutting Blade

As previously said, the Hyundai HYM40LI330P has a 33cm cutting width, which, while tiny in comparison to some other models, is great if you only have a small patch of grass to handle. Why spend more money on something bigger and useless when a nimble little gadget like this will suffice?

Roller (Stripes)

You’ll need a trustworthy roller if you want to achieve that English country garden perfection for your lawn, and you won’t be disappointed with this one because it has a beautiful tiny roller at the back of the machine.

There is a strategy to making the perfect striped lawn, but it becomes second nature with a little practise, especially when you have a lightweight mower like this that can make quick work of giving your grass a pleasant design. Keep in mind that because this is a lightweight mower, the stripes will not remain as long as those made with a heavy grass roller or gas mower.


While this one has a large grass gathering bag, it also has the option of going into mulching mode, which is made simple by the mulching plug on this model.

By enabling this mode, your cuttings will be returned to the grass, giving it a boost in terms of fertilisation and leaving it looking healthier and greener – a popular choice among gardeners, but if you don’t want to use it, you can use the grass collection bag – what a versatile piece of equipment.

Grass Collection Container

The grass collection bag on the Hyundai HYM40LI330P is a good size, holding up to 30 litres. We said this machine was little yet mighty, and the large volume of this bag demonstrates that.

Because the design is all plastic, it’s easy to empty, so you won’t have to sacrifice mowing time. Furthermore, because of the large capacity, you won’t have to make as many journeys to the compost or bin as you would with other mowers.

When you hit the first bump with some of the mowers I’ve tested, the grass box is prone to bouncing off. With this mower, however, this is not the case.

One of the best things about a cordless mower is that there are no cumbersome cables to get in the way of safe operation. However, there are a slew of other useful features that make this mower a joy to operate.
A foldable design, for example, is an excellent illustration of how to make storage easy. The handles on the Hyundai HYM40LI330P fold without tools at both the midpoint and the lower/deck point, which is a unique feature not found on other mowers. The mower is compact for convenient storage once the handles are folded and the grass collection box is removed.

Furthermore, the materials utilised in the design make it exceptionally lightweight, weighing just over 11kg, ensuring that you will not strain your back when moving or lifting it.

Furthermore, it is constructed of strong, durable polymers that will withstand the environment, ensuring that the mower will not rust or corrode, ensuring that its function is never jeopardised.

However, in the unlikely event that something goes wrong, you’ll be covered by a 3-year guarantee, ensuring that you’ll never be out of cash or without a good lawn mower.

But what we really like about it is that it comes almost completely assembled out of the box, allowing you to get outdoors and mowing in minutes – since no matter our age, we all want to try out a new toy as soon as it arrives.

Finally, you’re getting a machine that requires little to no maintenance, saving you time and money, thanks to the lack of oil changes, spark plug replacements, and air filter checks that you’d find on a petrol mower. It’s also a much more environmentally friendly option.

The Hyundai HYM40LI330P is extremely safe to use because it requires the insertion of a safety key before it will turn on. Working with power or electric tools carries a lot of potential safety dangers, therefore I think this is a great little feature that prioritises safety.

Of course, as I previously stated, the lack of power lines contributes to the safety of this device, as it eliminates tripping and the risk of mowing over the cord.

Is It Worth Buying This Model?

You can’t go wrong with this cordless mower when it comes to getting good value for your money. You’d be hard pressed to find something more reasonably priced for the features you’re receiving for less than £200. So, if you’re looking for a way to save money, this is the place to go.
Anyone with a small or medium lawn will find this really useful, as long as they don’t require a lot of cutting height alternatives. The 33cm cutting breadth is large enough to handle a medium-sized grass with ease.

Because of the rapid charging option, grass collection bag, mulching mode, and the inclusion of a roller for making stripes, this is definitely worth considering if you’re looking for a mower that will provide you variety.


The Hyundai HYM40LI330P is a fantastic cordless lawn mower that is simple to operate and has a lot of features. It’s powered by a 2.5Ah battery that provides enough power to cut the entire grass in 80 minutes (30 minutes with rapid recharge).

I would definitely agree that this is a great option for a first-time cordless mower because it is inexpensive and provides a solid overview of the characteristics that a good cordless mower should have. When compared to the slightly larger Hyundai HYM40LI380P, it’s easy to understand why this is the preferable alternative for those who don’t require a heavy-duty vehicle. Is this something I’d recommend? Absolutely.
