Product Analysis

30-Degree Nanotech Blades:

To be fair the blades of Panasonic Arc4 are among the best that there is.

The blades are forged and honed to an acute 30-degree cutting edge to give you a  very efficient cutting action.

The head of the razor as the name suggests ARC4 is made out of four cutting elements with outer blades.

The outer two are the typical blades that oscillate behind a foil screen and are the main reason behind the bulk of the shaving action.

The middle ones are integrated into the foil and work together with the outer ones to give you an efficient shaving experience.

Mechanics of Blades:

On the inside of the shaving head, it has two foils that catch and cut the hair which falls through the outer blades.

When you turn on the shaver the inner two blades get engaged and catch the finer hair.

The upper ones are designed to shave thicker and longer stubble hair.

With this mechanical design, you don’t really have to go back to the areas after the initial shave as it eliminates most of the hair and gives you a smoothe shave.

Four-Blade Nanotech System:

The Panasonic ES8243A Arc4 is built with four patented nanotech blades that sit on the outside of the foil.

There are two inner blades that side the razor which is designed with a special coating that makes them twice as sharp as the standard blades.

The whole system is designed to capture and hold the hair to deliver a cleaner cut at the base of the follicle.

Being stainless steel and hypoallergenic the shaver provides a closer and more comfortable shave for any skin type without causing any kind of irritation.

People who have sensitive skin tend to experience a razor burn and itchiness even if they are using razors that are marketed towards men with sensitive skin.

Battery Life:

The Panasonic ES8243A Arc4 has Lithium-Ion Rechargeable batteries which make charging very easy.

In about an hour the razer can be fully charged and can provide enough power for about forty-five minutes of usage.

This might not seem anything out of the ordinary just a normal battery life you would expect from a quality shaver.

An important thing to note is that the razor should not be left plugged in for more than one hour as doing so repeatedly will affect the performance of the battery in time.

Just like most electric shavers for wet shaving, you can not use the Panasonic ES8243A Arc4 while you are charging it. it’s a safety precaution and

this should not be considered as a negative aspect especially since there is a five-minute quick charge option in the shaver.

Wet and Dry Shaver:

The Panasonic es8243aa comes with Wet/dry shaving technology.

The shaver allows you to have quick shaves and also a refreshing wet shave with shaving cream, gel, foam, soap, or water.

LCD Display:

The built-in LCD display shows the remaining battery percentages when it reaches increments of percentage and also the duration of the shave in minutes and seconds.

This comes to great help when you are about to start shaving.

It packs with an automatic voltage conversion and adapts to any voltage between 100-240 volts which comes in handy when you are traveling abroad.

Pop-up Timmer:

Worried about your sideburns? You don’t have to.

Yes the Panasonic ES8243A Arc4 does come with a pop-up trimmer at the back of the shaver.

When you want to use it just pop it up which is not only good for the sideburns around the ears but also for the mustaches.

Even your mustache and your neck hairs to get rid of it.

Shaving with Power:

The Panasonic ES8243A Arc4 might be lightweight but the razor packs a powerful punch.

It is built with Panasonic linear motor drive which delivers 13,000 cuts per minute.

Yes, that is a lot more than the standard razors in the market today which runs at around 8,000 to 10,000 cuts per minute on average.

This extra power gives you a closer and smoother shave without tugging or pulling your hair or skin.

The power of the motor combined with the flexible pivoting shaving head.

This means that the razor can be moved in a circular motion as it glides over to your chin, neck, jaw, and on your face.

If that is not enough power feature for a razor, Panasonic Arc took power to the next level.

The shaver can maintain peak battery life power all the way until the end of the charge.

Unlike other shavers which slow down and start to shave unevenly as the battery drains out.

Cleaning and Maintenance:

Like the Braun Series 9 and the Panasonic Arc5, this shaver does not come with a cleaning station.

However, as being waterproof and easy to clean manually you don’t really need a cleaning station for it.

As it is super easy to clean all you need is a bit of liquid soap and some warm tap water and to ensure a proper cleaning.

The razor features Panasonic’s Turbo cleaning mode which should be used when the faucet symbol displays in the LCD display.

Built Quality

The ergonomic design and the shape of the shaver make handling easier to manipulate for any user.

At only 6.2 ounces or approximately 176 grams, the razor is very lightweight.

The head of the razor is loaded with springs which allows it to tilt along the facial contours.

And if you want to restrict the head movement, it can easily be switched to the locked position.

The manufacturer suggests replacing the outer foil after every six months.

The foil actually lasts much longer than six months because the cord is just a straight cord and it isn’t really coiled.

Weight and Dimension:

The Panasonic ES8243AA Arc4 razor is pretty lightweight with only being 6.2 ounces or approximately 176 grams and the product dimension being 9.6x3x7.

The most important part of all is the actual shaving performance.

The Panasonic ES8243AA Arc4 electric shaver is advertised as a one pass shaver.

But in reality, you will find that there simply isn’t a thing like that but that does not mean its bad.

It will still deliver an excellent shaving experience.

The four cutter shaving head can cover large areas very quickly.

Its built-in powerful motor and sharp blades makes the razor one of the most capable electric shavers in this price range.

The closeness of the shaver with your skin will satisfy almost anyone being on par with what you will get from much more expensive shavers.

A person with coarse facial hair will benefit from the powerful motor and the sharp blades.

A pre-electric shaving lotion will improve the comfort and the performance of the shaver and will also help straight the hairs stay flat on your skin.

Unlike other brands, the Panasonic shaver does not get clogged with shaving creams and you can easily rinse it with water if you need to.

The pop-up trimmer works like a charm for basic grooming.

But a problem that occurs is the placement of it. The shaving head is so big that it becomes difficult to see what you are doing.

An easier way is to simply remove the shaving head and the inner blades when using the trimmer.

The Downside

While it is an excellent shaver of its range it can be a bit noisy not exactly extremely loud but it isn’t quiet either.

Be cautious about the turbo mode.

When you are in the turbo mode and you really don’t want to use it for shaving, just keep it for cleaning as it is extremely powerful and can cause harm to your face.

The ideal use of the turbo mode is only for cleaning the shaver.

The button for on and off might be in an awkward place right where your thumb would end up placing when holding the razor.

The plastic protector for the razor head is a bit difficult to snap back into place.

The shaver cannot be used while it is charging. The replacements of the foils and the blades are a bit expensive.

When shaving for detail work around the mustaches and goatees the shaping of it becomes a problem as the head is a bit too big.

The shaving head also blocks the view of work with the trimmer.

You could face some difficulties when doing your neck hairs. When the foil and the blades become dull you need to replace them.

The blades and foil can be purchased separately or you can buy it individually as well.

The LCD screen does let you know when you have to replace them.


For the men with medium to coarse facial hair, the shaver works really well for daily shaving.

If you suffer from post-shaving irritation or razor burn, the Panasonic ES8243 is a viable option if you use it with shaving cream.

Without any doubt, it is an all-around great performer for both dry and wet shaving and gives you your full money’s worth.

It is hard to find other foil shavers in this price range that performs better than this one.
