Since 1919 the Wahl Clipper company has been designing and manufacturing professional grooming tools both for professional barbers and home consumers.

The Wahl 9818 Litium Ion All-in One groomer continues the tradition set almost 100 years ago.

This is truly an all-in-one groomer with plenty of attachments to groom the hair anywhere on the body from the top of the head to those stray toe hairs.

My initial impression

Wahl 9818 Litium Ion stainless steel All-in One groomerThe first thing that always catches our eyes is the look and ease of use for any grooming product.

The Wahl 9818 Litium Ion stainless steel All-in One groomer certainly gets a high score from me for having an elegant design and more importantly the slim look which will not give you any blind spots.

Nothing more annoying than using a bulky trimmer and the body of the trimmer coming in the way while trimming or outlining your beard.

The other thing important to mention right from the start is that for those maintaining a very close stubble style or a shadow look, this trimmer may not be the right one for them.

It will work fine for a heavier stubble look or you can also use the blades directly on your skin without any guide but that would most likely give you a very close shave.

So, if you need a maintain and short stubble, my suggestion would be to look for a trimmer which is designed specifically for stubble look.

The Wahl 9818 comes with an endless supply of attachments most of which you may never use but we will run through all the accessories to determine their utility.

The Not So Good: It appears that Wahl may have some quality control issues as several users have reported problems with the power switch. We will discuss this issue in detail later in this review under the heading “Battery & Power”.

I have provided a table of contents and you can jump straight to that section if you would like to read that first.

Features At A Glance

The Wahl 9818 Lithium ion stainless steel all-in-one groomer is designed to meet all of the hair grooming needs of the modern man. Features of this groomer include:

  • 4 interchangeable heads.
  • Heavy duty stainless steel body and blades.
  • Designed to outline, trim and do touch ups with ease.
  • 3 step light tells when the battery is low and the groomer is charged.
  • 120-240 Volt.
  • 8 guide combs.
  • 6 position trimming guide.

Hair Length Settings & Combs

One of the attachments is a 6 position trimming guide which is easy to attach and remove. This will give you from 2mm to 12mm lengths with an increment of 2mm between each setting.

If your trimming length fits within one of these settings, you won´t really need any combs as this one guide will suffice. Besides, the manual gives you clear instructions for attaching and using it.

It also comes with 8 guide combs which snap on and off with ease. Here is a chart that will show you the measurements.

No.1 – 1/8″ (3mm)
No.2 – 1/4″ (6mm)
No.3 – 3/8″ (10mm)
No.4 – 1/2″ (13mm)
No.5 – 5/8″ (16mm)
No.6 – 3/4″ (19mm)
No.7 – 7/8″ (22mm)
No.8 – 1″    (25mm)

If you need a comb larger than 1” you can get that directly from Wahl to give yourself a haircut although I think that the trimmer width is too narrow for a haircut. There are mixed opinions from the users with some saying that they felt the power was not sufficient for a haircut while others reporting they have had no problems.

Ideally, it is only meant for tidying up head hair and it is highly recommended for all other grooming needs such as, beards, mustache, neckline, sideburns, nose and ears.

Blades, Cleaning & Maintenance

Wahl 9818 Litium Ion stainless steel All-in One groomerFor all these grooming jobs, Wahl 9818 All-In-One comes with 4 changeable heads including:

  • T-Blade Trimmer Head provides you with that extra width needed to cover bigger areas as well as give yourself a haircut. It also gives you a close shave for a very close stubble and is good for outlining on the neck and shaving hair.
  • Detail Trimmer is a much narrower blade and my favorite tool for precise outlining. So it is effective for hard to reach areas.
  • Detail Shaver Head is suitable for shaving and outlining work although some users have reported that it does not give as close shave as a conventional shaver does.
  • Ear & Nose Trimmer seems to be of good quality and you don´t feel pulling of hair.

You can also buy additional heads from Wahl (the one I found quite useful is a 3 heads rotary shaver) and you will have a complete grooming tool at home.

It comes with self-sharpening blades which are made of high compression and high carbon steel to ensure their quality of sharpness for a very long time.

Apart from a small number of users out of hundreds who were not so satisfied with the cutting performance, all the others gave a very high rating and were extremely pleased with the sharpness and durability of the blades.

The blades are not washable, so you should only use the brush provided to clean them in order to avoid any rust appearing.

The manufacturers recommend applying few drops of oil at least once a month to maintain the quality.

Battery, Power & Cord

As I mentioned in the beginning of the review, there seems to be a number of users complaining about the on/off switch. Most of them have reported the same problem that the trimmer does not go off or at times it turns on on its own.

If that happened to me I would feel like I am living in a haunted house but joking aside, this seems to be a matter of concern. On the positive side, all such users reported the problem to Wahl and they were very impressed with the service. Whal immediately despatched them a new trimmer.

Some users wrote a very negative review but after the great service they got from Wahl, they came back to add their comments of complete satisfaction for the customer service they received.

The trimmer comes with a stopper button which you insert at the back of the trimmer to lock it shut. This button is primarlily meant for travelling purposes so that the tool does not come on in your suitcase.

You can use this button as a temporary measure to shut the trimmer until Wahl can send you another one.

Here, I must also mention that there were many other users who never had this problem.

So, a logical conclusion could be that there was a faulty batch in the production line and some of us ended up suffering the consequences.

Wahl as we all know is an extremely reputable company and I am fairly certain that they would have addressed the problem so that they don´t loose their credibility in this highly competitive market.

Moving on to the next feature, this is a cordless trimmer which means you cannot plug it in for charging and use it at the same time. This can be a hassle if you forgot to charge it the last time it was used but the problem is easily solved since the trimmer has a quick 1 minute charge which is a great feature. You just let it charge for 1 minute and it will give you 3 minutes run time for those quick tidying jobs.

It comes with an all powerful Lithium Ion battery which is known for holding the charge even for months. You only have to remember once in a while to charge it and you will not face any problem. It also has a flashing warning light which will tell you when it needs charging.

It comes with a dual voltage (110V & 220V.) So, no problem there if you are living in Europe, in the East or if you are travelling.

When I first heard the sound of the motor, I was surprised how quiet it is unlike some other ones which can be very annoying when they are so close to your ears while trimming your beard.

It also comes with a small plastic stand. Some people are not happy with the quality of plastic but for me it´s a minor issue since I prefer to have a smaller stand just to hold the trimmer instead of a huge thing occupying space in the bathroom.

Consumer Reviews & Ratings

Reviews for the Wahl 9818 all-in-one groomer run from between the high end of average to the low end of good ratings.

While many users feel that this grooming tool does everything it is meant to do and even more, there are also some dissatisfied customers who felt that they did not get what they wanted or expected from this groomer.

Still, the fact that it gets an overall rating of 4 stars on various online stores, it gives a clear indication as to the number of happy customers. So, let’s take a look at what users liked and didn’t like about this particular trimmer.

As I like to hear the bad news first, so let´s talk about what they didn´t like.

Cons:

There were several things that some users did not like about it. Following are the problems the users incurred:

  • A majority of the users felt that the guides were not well made, and stated that some of the guides broke shortly after purchase. While it is impossible to know if any of these users contacted Wahl regarding this problem, there are some positive reviews from users who did contact Wahl and got a guide replaced free of charge.
  • Some users had a difficulty getting this groomer to turn on and off  while others experienced problems simply with shutting off the groomer.
  • Problems with water in the unit ruining the groomer. This is clearly because the groomer is not meant to be used for wet trimming and the problem of getting water in the unit could be a basis for some of the other problems users are experiencing.

Pros:

The majority of the people who purchased the Wahl 9818 Groomer actually like it and find it to be the groomer they had been looking for.

It should be noted that the positive reviews come from people who have used it on their head, goatee or full beards, sideburns and the back of their neck as well as those who have used the nose clippers. Here are some of the things that these users like:

  • Solidly constructed and it doesn’t feel cheap or plastic.
  • Lots of attachments to choose from to give you the exact trim you are looking for.
  • Attachments snap on and come off easily.
  • Holds a charge for a very long time.
  • The size makes this trimmer easy to position and get into the smaller, more difficult places around the nose and mouth or behind the ears and other places.
  • 5 years Warranty.

Design & Feel

It gets full marks both for the design and feel. The stainless steel body looks elegant and very easy to clean. It also feels quite solid in your hand.

Although the parts might have been made in China, the final assembly is done in USA and you can tell that it has passed strict quality control measures.

Dimensions & Storage

Dimensions: 1.2 x 1.4 x 6.2 inches.
Weight:         12.8 ounces.

It comes with a pouch to store lots of attachements provided.

Price & Warranty

You can tell the confidence Wahl has on its quality since they are offering a generous 5 years warranty.

It´s certainly not a cheap trimmer but as the famous saying “you get what you pay for”sums it all up.

Conclusion

I would be reluctant to suggest it for those wanting a very close stubble but for all other grooming needs, it seems to be a good trimmer and body groomer. Certainly a good all rounder to have at home.

My only negative thought is about the on/off switch and having to send it back to have it replaced if you were to face such a problem. But I am very impressed and satisfied with the after sale service of Wahl and we have seen the proof by going through the customers comments.
