This electric shaver from Panasonic is one of their best sellers. It offers a nice mix of convenience and performance. It also has a powerful motor for the toughest of jobs. This unit is capable of dry and wet shaving but is also waterproof 100% for easier cleaning and use in the shower.

The Panasonic ES8243A is the best electric shaver under 100 dollars on our test thanks to some great features and ease of use. If you don’t need the extra benefit or cost of a cleaning and charging station, this is the model for you.


In comparison to other shavers, The ES8243A lightweight, but that doesn’t affect the overall feel. It employs rubber-like materials that offer a firm grip, especially when you use it in the shower or with wet hands. The build quality is top notch; this Panasonic seems reliable and robust.

The black, gray, and shades of blue in this model’s color scheme may not suit everyone. We found it aesthetically pleasing, even though it’s not as classy and sleek as some shavers.

Arc4 linear motor

The cutting blades on this electric shaver get power from a linear motor. The motor shaves at speeds of 13,000 cycles per minute (CPM). That way you don’t have to make as many passes to get the job done. For a bit of perspective, most units operate at 8,000 – 10,000 CPM. There is also a turbo mode which increases the CPM and shuts off after about 20 seconds.


LCD Indicator

The ES8243A shaver has an LCD at its base that shows valuable information. With a quick glance, you can check battery levels and how many minutes you’ve been shaving. There’s also a light that shows charge levels during charging. Finally, the LCD will let you know when you need to clean this unit or replace the blade and foil.


Battery & charging

The charging time on this electric shaver is about one hour. After a full charge, you can use it for around 45 minutes without pause. The autonomy and charge-time are what we expect from higher quality models. One thing worth mentioning is that you shouldn’t leave this unit plugged in for more than an hour. Doing so can damage the battery over time

Shaving performance

To make sure this electric shaver conforms to the contours of your face, it has a flexible pivoting head. This design results in a smooth shave and easy use. Another great feature is the built-in trimmer. You can pop it out to cut areas like your mustache and sideburns, but its placement can cause problems.

This model also comes with ultra-thin arc foils made out of stainless-steel. They can lift flattened hairs, capture and hold them with more efficiency during cutting. The blades sit at a 30-degree angle which gives a close shave each time. The large shaving head can cover bigger areas in a short amount of time but can make detail work harder. These blades are hypoallergenic and designed for sensitive skin. Thus, the Panasonic ES8243A Arc4 is one of the better, if not the best electric shavers for sensitive skin.

Because this model is waterproof, you can use it for wet and dry shaving. This also means you can quickly clean it under running water. For us, this is the best way to clean electric shaver if you don’t have a cleaning station.


Considering everything the Panasonic ES8243A Arc4 offers, it’s an enticing model. It has an excellent motor that powers a great set of blades. With this combination, you won’t have trouble cutting through the toughest of stubble. Also if your battery is dead, and you’re in a rush, you can use the 5-minute quick charge option. Finally, there’s an automatic converter for voltage hidden inside this electric shaver. It can adapt to voltages of 110v – 240v which is perfect for those who like to travel.

The large head is ideal when shaving bigger areas, but a bit trickier when used near your nose. One of the downsides is that the foils and blades need to be replaced each year. Right now they cost about 50$ and are a bit pricey.
