Shop Panasonic ES8243A Arc 4

Buy it from Amazon

The ES8243A Arc 4 is one of Panasonic’s best-selling electric shavers, offering a great blend of performance and costs.

It’s fitted with a powerful motor, sharp blades and has rock solid build quality.

And to make the deal even sweeter, it is also quite reasonably priced considering that you’ll be getting a lot of shaver for your money.

Read along for our in-depth Panasonic ES8243A review and find out if it’s the right shaver for you.

Features overview

The Panasonic ES8243A Arc 4 can be considered an upgrade to the already excellent and highly popular ES8103S from the Arc 3 line.

The shaver was beefed-up by adding a fourth cutting element to the shaving head, called a finishing foil that should cut the stubble really close to the skin.

Here are the key features:

13 000 RPM motor

This razor features the same excellent high-speed linear-drive motor found on may other Panasonic models.

Even though Panasonic managed to bump the speed up to 14 000 CPM (cycles per minute) in some of its other more expensive shavers from the Arc 4 family, 13 000 is still enough, especially when considering that other manufacturers don’t come close to those numbers.

See the price on Amazon

I’m talking of course about Braun that uses 10 000 CPM units even for the high-end shavers like the Series 7 or Series 9.

Having a powerful motor also has a minor downside, meaning that this is not the quietest foil shaver out there and the foils can get a bit hot after prolonged use.

However, the advantages outweigh these shortcomings.

30 degrees hypoallergenic nanotech blades

Gimmicky name aside, these blades that have been around for a while in Panasonic’s shavers are among the best.

The aggressive 30-degree bevel ensures a very efficient cutting action, with no pulling or tugging.

The nanoblades with the 30 degrees angle

The shaving head, as the name Arc 4 suggests, is made out of 4 cutting elements.

The outer two are the typical inner blades that oscillate behind a foil screen and are responsible for the bulk of the shaving action.

The Arc 4 foil block and two inner blades

The ones in the middle are integrated into the foil block and work together with the outer ones to shave more efficiently.

One of them features a special design, with long slits that will trim down the longer hairs to a more manageable length and are then cut close to the skin.

We’ll see later on in the review how well it actually performs.

Flexible pivoting head

The shaving head of the Panasonic ES8243A can move back and forth and also from left to right, supposedly ensuring better contact with the skin and making it easier to follow the contours of the face.

The foils are also slightly curved for the same reason.

You can lock the head into a fixed position with a switch located on the side of the razor.

Other features that will be covered later on are:

  • Popup trimmer
  • 10 stage LCD display
  • Wet & dry use
  • 100% waterproof
  • 5 minute Quick charge option

Build quality and ergonomics

Compared to other shavers, the ES8243A is lightweight and well balanced. It is also very comfortable to operate and the rubberized inserts on the sides and back ensure a very secure grip.

The back of the ES8243A

As far as aesthetics go, I was always a fan of the futuristic, hammerhead-like design of Panasonic razors.

This one is no exception and it looks excellent in my opinion, although not as classy as the top of the line Braun or Norelco shavers.

See the price on Amazon

Build quality is also excellent and everything feels solid and robust, despite an all plastic build.

Battery life and charging

The razor can be fully charged in about one hour and should provide enough power for 45 minutes of use. Nothing out of the ordinary, just the normal battery life you would expect from a quality shaver.

As it’s the case with all the electric shavers that can be used for wet shaving, you can’t use the ES8243A while charging.

This is a safety precaution and we won’t consider it to be a negative aspect anymore, especially since there’s a 5-minute quick charge option.

The LCD display shows the remaining battery in percentages in increments of 10%, but also the duration of the shave in minutes and seconds.

This is very handy in my opinion and I wish more electric razor would have this feature.

The automatic voltage conversion adapts to any voltage between 100-240v, so you can also use it when traveling abroad.

Cleaning and maintenance

As you probably know, the shaver doesn’t come with a cleaning station. Given the fact that the ES8243A is fully waterproof and dead easy to clean manually, you won’t really feel the need for an automated cleaning system.

Cleaning only requires a bit of liquid hand soap and warm tap water.

To ensure proper cleaning, the razor features Panasonic’s Turbo cleaning mode that should be used when the faucet symbol appears on the LCD display.

To activate the Turbo mode (which bumps the speed from 13 000 to 17 000 CPM) you must press and hold the ON/OFF switch for more than 2 seconds. It will automatically stop after 20 seconds.

Shaving performance

And now let’s get to the most important part of our ES8243A review, the actual shaving performance.

The ES8243A is advertised by Panasonic as a one pass shaver. Although in practice you’ll find that there simply isn’t such a thing, this razor will indeed deliver an excellent shaving experience.

The massive, 4 cutter shaving head can cover large areas very quickly.

This, coupled with a powerful motor and sharp blades make the Panasonic ES8243A one of the most capable electric shavers in this price range.

The closeness of the shave will satisfy almost everyone, being almost on par with what you’ll get from much more expensive shavers like the Arc 5.

See the price on Amazon

The most impressive thing about it is just how fast and close it shaves, especially when used on a shorter beard. Men with coarse facial hair will particularly benefit from the powerful motor and the sharp blades.

Using a pre-electric shaving lotion will further improve the comfort and the performance of the shaver; it will also help straighten the hairs that stay flat on your skin because it can struggle with some of those, especially if they also grow in different directions.

The Panasonic ES8243A can also be used for wet shaving, where it simply shines. It doesn’t get clogged with shaving cream and you can easily rinse it with water if you need to.

I find the closeness and particularly the comfort much better when used with shaving cream.

And this leads us to one of the potential downsides of the ES8243A  — it’s not the most comfortable shaver in this price range.

If you don’t have sensitive skin you’ll probably be just fine; otherwise, a Braun Series 5 will likely be a better option.

Finally, there’s the popup trimmer; while it does perform well and works excellent for basic grooming, it has the same problem as most Panasonic shavers.

The placement, together with the fact that the shaving head is so big means that you simply can’t see what you’re doing.

One thing that seems to work is to have the shaving head and the inner blades removed before using the trimmer.

Of course, one downside of having a large shaving head is that it can be somewhat unpractical for detail work, like shaving the base of your sideburns, upper lip area or around a goatee.

This is a thing to keep in mind for some men, but I think the benefits you get from a large shaving head far outweigh this shortcoming.

As for other negative aspects of the shaving performance, there is the always tricky neck area, that requires multiple passes to get a close shave, especially if you have hairs that stay flat on your skin.

Shaving more often can reduce this problem to a minimum.

Included accessories

ES8243A accessories

Apart from the shaver, in the box you’ll find the following items:

  • Power cord
  • Travel case
  • Plastic protective cap
  • User’s manual

Replacement parts availability

Changing the blades and foil of your shaver must be done once a year. Unfortunately, the replacement parts for this shaver are a bit pricier than what you would expect.

You can buy them in two flavors:

I recommend changing both the foil and inner blades as you won’t get the best out of your shaver by using a worn part together with a new one.

Wrapup—Who should buy it?

This shaver has to be one of the top picks for men with medium to coarse facial hair and it works particularly well for shaving daily.

See the price on Amazon

However, you can get away with using it every other day or even more if you have a slower growth and still get excellent results.

If you suffer from post-shave irritation, razor burn and have a history of “bad shave days”, the Panasonic ES8243A can also be a viable option, especially if you use it with a pre-shave or shaving cream.

Given the fact that it is a solid, all around great performer for both dry and wet shaving, you can’t really go wrong with this one.

In terms of value for money, you will be hard pressed to find a foil shaver in this price range that performs a lot better.

Alternative shavers

As mentioned throughout this review, the Panasonic ES8243A Arc 4 is definitely one of the best electric shavers in this price range.

However, one of the (few) complains about it is that you can’t have it with a cleaning and charging station.

If you really must have one, there is another shaver from the Arc 4 line that comes with one, the ES-LA93-K.

Panasonic ES-LA93-K


See the price on Amazon

I would personally skip the cleaning station, but if you really must have one with your Panasonic shaver, the ES-LA93-K is a good option.

For men with very sensitive skin, a Braun Series 5 is more comfortable out of the box. They are also better with longer, flat-lying hairs. There are several variations available, but all of them are generally more expensive.

Braun Series 5 5090cc/5190cc


See the price on Amazon

The Series 5 5090cc that I reviewed here is probably the best in terms of value for money as it also comes with an automatic cleaning station.

And unlike Panasonic shavers, the ones from Braun are more difficult and fiddly to clean manually. So you’ll definitely want the cleaning station as well.

Finally, there’s what I currently consider to be the pick of the Arc 4 line.

It’s called the ES-LF51-A and you can check out my review of it here.

See the price on Amazon

It has a slightly more powerful motor than the ES8243A, a slightly smaller shaving head (even though it features the same 4 cutting blades) and comes with a travel lock as well.

And considering that it costs pretty much the same as the ES8243A, this one would be my pick.

    I have owned my ES8243 for several years and I like it very much.
    I do have one issue, and that is, that there is one icon that appears on the display that is not mentioned in the manual, hence I do not know what it means or how to clear it. Nowhere on the Internet have I found a complete explanations of the icons. This particular icon shows the shaving his with two curved arrows circling it.

    1. Thomas Lee

      Hi Bill, it means you should check the inner blades and foil. It’s towards the back of the manual. All you need to do is hold the power button for 30 seconds and it’ll clear it out

  3. Brad

    Does anyone who owns one of these models use it on their head? I grow a full head of hair and shave it every 2 days. St three days, my head is pretty fuzzy…

    1. Ovidiu Nicolae Post author

      Hi Alex,

      I currently do not have this particular model in my possession anymore, but based on the measurement of other similar Panasonic shavers, I would say that the length of the display is little over 3cm and width is around 2cm at the top.

    1. Ovidiu Nicolae Post author

      There isn’t any difference between the actual shavers. Both ES8243A and ES8243 refer to the same product. Depending on where you buy it (America, Europe etc.) it may be available under several names.

  4. Barbaro

    HI Ovidiu,
    I always enjoy your reviews and would like to ask a question.
    Are there any differences between the ES8243A Arc 4 and the ES- LA63- S Arc 4?
    Is it the same buying one or another given that the ES8243A Arc 4 is less expensive and seems a real bargain?


    1. Ovidiu Nicolae Post author

      Hi Barbaro,

      Thank you for your comment. There are a couple of differences, but I wouldn’t consider them significant. If you can get a great deal for the ES8243A, my recommendation would be to just go for it. The ES-LA63-S has a second vibrating motor inside the shaving head, but I didn’t notice an improvement compared to other Arc 4 models that don’t have this feature. The motor powering the ES-LA63-S is slightly more powerful at 14 000 CPM compared to 13 000 CPM, but again this is negligible in the real world.

      Performance-wise I think you’ll be happy with either of the two.


  5. Barbaro

    Hi Ovidiu,

    thanks for your reply. The difference I found is 20 dollars so it’s not that much: 79.99 vs 99.99 for the ES-LA63-S so I think I’ll get the latter.

    Replacement foil and blades, only 2 two blades, the two worm blades don’t seem to be available for replacement. where can these two blades purchased. Parts #

    1. Ovidiu Nicolae Post author

      The two inner blades can be bought from Amazon (you can find the link to the correct part in the review).

  7. B Kishimoto

    The trimmer on my Panasonic ES8243 Shaver does not cut anymore. I think the Trimmer Bar does not engage with the cutter unit. Can you instruct how to re-engage the parts together again?

    1. Ovidiu Nicolae Post author


      I remember having a similar problem with an older ES-LF51-A. In my case a small plastic bit from the mechanism (that basically linked the motor to the trimmer) snapped out of its location. I managed to put it back in using the tip of a small screwdriver. It would be difficult to say what exactly is wrong with your trimmer, but it could be a similar issue. It may be fixable depending on what is wrong, but again it is almost impossible for me to give you any advice without actually seeing it.

      Pop open the trimmer and turn the shaver on. At the base of the trimmer you should see a small plastic piece oscillating. That in turn acts on a small lever that is directly attached to the cutter. If it’s not moving, the cutter may be jammed (because of dirt, hardened soap or lather, etc.) or as I mentioned earlier, it is disconnected from the motor. If you can provide a closeup photo (or video) of it I may be able to see what’s wrong.

    Hi Ovidiu,
    I enjoy very much reading your informative articles.
    I’m considering buying this model since it is offered in a good price but I would love to hear a second opinion.
    I usually trim my beard and from time to time I use blades to have a clean shave, meaning, I’m not a heavy shaver… Do you think this model, in its age, will be sufficient for me or should I go with the newer models (which are almost double the price).
    Also, I’m considering shaving my head with the shaver I’ll purchase, do you think this shaver will do the job?

    1. Ovidiu Nicolae Post author

      Hi Omri,

      Thank for your comment, much appreciated.

      I think it will be suitable for occasional shaving, provided that your beard is reasonably short (around 2 to 2.5mm). If you pre-trim your beard to that length, it should work just fine. Same goes for shaving the head, the key is to use it on short hair, otherwise it will likely miss some and shaving will take a lot longer.
