See on Amazon

The PowerTouch line of electric shavers from Philips was always popular due to the low price and surprisingly good shaving performance.

In this review we take an in-depth look at the Philips Norelco Shaver 4100 (AT810/41) from the Series 4000, a razor that just might be one of the best budget rotary shavers you can get.

Read along for the full test and find out how it performed.

Features overview

A few months ago I reviewed the Norelco 3500 and it delivered a solid performance, but with two pretty big shortcomings: charging it took a whopping 8 hours and it couldn’t be used for wet shaving in the shower.

The Philips Norelco Shaver 4100 addresses those exact issues and it does that for just a marginal price difference.

As mentioned previously, the 4100 and 3500 are basically identical, with the difference that the former is fully waterproof and can be used with shaving gels and creams and the charging time is greatly improved.

Here are the main features of the Philips Norelco 4100:

  • DualPrecision Shaving Head—the rotating elements have wide slots for cutting long hairs and holes for shaving very short hairs;
  • Super Lift & Cut—one of the main features of the 4100 is the system patented by Philips to cut the hair close to the skin: one blade lifts the stubble, while a second one cuts it below skin level (at least according to Philips);
  • Flexing Shaving System—the three shaving heads are low-friction and rounded to further reduce the irritation of the skin. The flexing feature ensures that they are in better contact with the skin and should be more effective when shaving tricky areas like the neck and jawline;
  • Wet and dry shaving—this is a welcome feature for all the gents that enjoy shaving with gels or cream. All Philips shavers that have the Aquatec logo are fully waterproof and can be safely used when showering;
  • Popup Precision Trimmer;
  • Fully waterproof;
  • 3-Minute Quick Charge;
  • 50 minutes of cordless use from one charge;
  • LED indicator for battery full, battery low and charging.

Build quality and ergonomics

The 4100 feels very light and comfortable to hold and even though the materials don’t look that posh, it is well built.

Philips 4100 design

The color scheme is also more attractive than the one on the Norelco 3500 with a combination of aqua blue, silver, and black.

The front of the razor features the LED and the ON/OFF switch, which is covered in a rubberized material that extends to the sides. This ensures a very secure grip, even when it’s wet.

The back of the razor is just a plain, matte black plastic with nothing but the popup trimmer.

The very basic battery indicator is my main gripe with the ergonomics of the Philips 4100. Other shavers that are priced similarly often come with a 2 or even 3-level battery indicator, which is a lot more useful than just a low-battery LED.

Battery life and charging

The Norelco 4100 comes with a Li-ion battery that takes about one hour to fully charge and will provide enough power for 50 minutes of use.

There is also a 3-minute quick charge option that will come in very handy since you can’t use the shaver while it is plugged in.

This is a safety feature that is present in all shavers that can be used in the shower.

Also, being a Li-Ion battery means that you can charge it whenever you like without the fear of affecting it in any way.

Cleaning and maintenance

Cleaning the shaver is very simple: you just pop the shaving head open and rinse it under running tap water.

You can also choose to use the brush that comes in the package, but cleaning with water is a lot more effective.

This quick clean takes little time and it’s very easy to do.

However, every once in a while it’s a good idea to clean each of the three shaving heads to remove any hairs and grime lodged inside the combs.

This implies taking the shaving unit apart and cleaning each cutter and comb, making sure not to mix them up as they are matching pairs.

Shaving performance

The Norelco 4100 will provide a decent shave that will satisfy most men.

The closeness and comfort of the shave are very good for a rotary shaver in this price category.

See the price on Amazon

The rounded shaving elements glide smoothly on the skin, regardless if you shave wet or dry.

It does an especially good job when it is used for daily shaving, however it will perform decently even on longer hairs (around 3 days of growth), but don’t expect anything extraordinary.

Another pro is the ability to use it for wet shaving. While the dry operation performance was good, it can be further enhanced by using a shaving gel or cream.

As it’s the case with the very similar 3500, the motor is not as powerful as on more expensive Philips Norelco shavers and as a result, your shaving may take a little longer.

Where it might struggle a little is with long or very tough beards.

If you shave every 2 to 3 days or more you may experience some difficulties in getting a very close shave. In this case, you may want to spend some extra money on a more expensive and powerful rotary shaver.

Included accessories

As you would expect from a product in this price range, the retail package is pretty basic. In the box you’ll find the following items:

  • Philips Norelco Shaver 4100
  • Protective cap
  • Cleaning brush
  • Charging cord

Replacement parts availability

All the razors from the PowerTouch line use the same replacement part: Philips Norelco HQ8 cutter heads.

A newer and supposedly improved version of these cutters is now available, the SH50/52.

The part should last for at least one year before needing to be replaced.

Of course, this will vary; depending on your shaving routine and facial hair, you may need to change it sooner or later.

Wrapup—Who should buy the 4100?

All in all, the Philips Norelco 4100 is a solid, effective and decent shaver for this price range.

As mentioned in the performance section of our review, most men will be satisfied by the closeness of the shave, especially when it is used for shaving more often.

As a bonus, you can also use it with shaving gel in the shower.

With that in mind, it is a solid option for anyone looking for a quiet, robust, rotary shaver that doesn’t have a prohibitive price and will get the job done.

Also, if you shave your head and are looking for an inexpensive rotating shaver, look no further.

Of course it doesn’t have the bells and whistles of the more expensive Norelco shavers and that’s not necessarily a bad thing. There will be fewer things to break down and it will be very “cheap to run”.

If this is your first electric shaver, the fact that it is a simple, easy to maintain, waterproof shaver makes it an excellent option.

Alternative shavers

The Philips Norelco 3500 (PT730) is an identical shaver that costs slightly less money, but you can’t use it for wet shaving and it takes 8 hours to fully charge.

You do have the option to use it while it is plugged in though. So if you don’t care about these shortcomings, you can go for it as the (dry) shaving performance is identical.

If rotary shavers aren’t your thing, you have an excellent alternative for pretty much the same price: Panasonic ES8103S.

It is also a fantastic budget shaver that will likely provide a closer shave for most users. Do keep in mind that foil electric shavers are noisier than the rotating ones.

Either way, you can’t go wrong with any of these. Feel free to ask any questions in the comments section below.

  1. I have a question that relates to the 4500 which in some sense is very similar to the 4100 but with a different pivoting head and color. Years ago I used a Speed xl that took HQ9 heads. The 4500 and 4100 take HQ8 heads. Is it possible to fit an HQ9 head onto a 4500 body? In other words, will the drive spindles in the handle of the 4500 fit into the receptacles of the blades on the HQ9 heads? Thanks.

      • I actually tried it and the HQ8 (Old version) and SH50/52 (New version) heads are interchangeable with the triple track HQ9 heads. All of them have the same design anti rotation wings on the outer guard and interchange without a problem. The HQ9 heads gave a great shave with minimal irritation when installed in my Aquatec AT815 Series 4000 Shaver 4400, per all the designations on the box. Very comfortable shave with minimal irritation.

        • Thank you for your comment Rich — that’s very interesting and definitely useful to know. I was always under the impression that they are not interchangeable.


  2. Allow me to ask a further question that relates to the above but depends upon your own experience with these blades. Do you know whether or not the HQ9 heads shave closer and/or are more comfortable than the HQ 8 heads? I am a rotary shaver and am looking to buy a backup rotary shaver for my 9700 series. As mentioned, I had a Speed xl that used HQ 9 heads several years back and I’m able to get a used one on ebay. However, there are brand new Philips shavers (i.e. 4500, 4100) that use the HQ 8 heads that are available right now so it is a question of which might provide the better shave. It strikes me that the three rows on the HQ 9 heads should do the trick but I also have to keep in mind that these are older shavers whose life span may be very limited.

    • I’m afraid I cannot help you as I never had a shaver that uses the HQ9 heads. However, I think the performance should be fairly similar. There’s always a risk when buying a used shaver. I personally would opt for a new one even though it comes with the HQ8 heads.

      • Thanks for your input, Ovidiu. I’ve chosen to follow your advice and ordered the 4500. I did discover that the HQ8 heads have been discontinued for SH50 heads. I’m not certain exactly what difference this makes but when I contacted Philips regarding my order and my concern about HQ8 heads they told me they would send me the SH50 heads for me to try; one of the things I’ve always loved about this company. Thanks again.

        • No problem, Pavil. That really is good customer support. I hope you’ll be pleased with the shaver and with the newer heads as well.


  3. I am glad to know of the new sh 50/52 replacement blades. I have replaced my Norelco 2100 shaver’s blades with sh 30 replacement blades. Before I purchase the new sh 50/52 blades, I need to be assured that they will fit my Norelco 2100 shaver. Please tell me yes or no. Thank you, WEJ

    • Hi WEJ,

      No, the SH50/52 blades will not fit the Series 2000 models. The SH30 is the right part for your shaver.


  4. The Chinese online retailer, dh has a rotary-type electric shaver for sale, which I hope you will review for me. It lists for US $27.19, free shipping, and it is made by Kemei. Here is the description:
    Input Voltage: 220V 50-60Hz
    Power Consumption: 3V–100mA
    Charge time: 8 hour
    Please tell me what you know. Thanks, WEJ

  5. Please permit me to ask you about another electric, rotary-type shaver, which is offered on the Chinese online retailer, dh It is a Kemei model IPX7. Here is the description:

    Power Type: Rechargeable
    Feature: Triple Blade
    Use: Face
    Usage Time: 60Minutes
    Washing Mode: fully washable
    With Trimming Device: Yes
    Charging time: 6 Hours
    Voltage: 220V

    Thanks again, WEJ

    • Hi,

      I haven’t got the chance to try any of the shavers made by this brand, so I’m afraid I cannot give you any advice. I still have a few reviews lined up, but if I can get a Kemei shipped in Europe, I will be posting a review as well.


  6. I have used the Norelco AT830 for quite a while. Can you tell me what current Norelco razor would be an equivalent replacement?

    • Hi Gene,

      That would be the current Series 3000. The performance, form factor and so on are really similar, the big difference being that the Series 3000 comes with the SH30 blades which are in my opinion a lot more comfortable and forgiving than the SH50 of the AT830. Some users argue they don’t cut as close, but I haven’t found that to be the case.
