Keeping a beard neat, trimming your hair, and dealing with nose or ear hair can require several tools if your grooming kit is too limited. The Philips Norelco All-in-One 3000 Series MG3919/50 combines 13 tools and accessories with trimming lengths from 0.5mm to 16mm, so you can handle several routine grooming jobs with one cordless device. Its rounded-tip, self-sharpening blade design and 60-minute runtime are useful strengths, but the eight-hour charging time and lack of an included wall adapter are worth knowing before you buy. This review explains where the MG3919/50 works well, where it compromises, and who will get the most value from it.
Quick Verdict
Rating: 8.4/10
Best For: Everyday beard trimming, basic home haircuts, stubble maintenance, and nose or ear grooming.
Bottom Line: The Philips Norelco MG3919/50 is a practical all-in-one kit for buyers who want several fixed trimming lengths without moving to a more expensive grooming system. Its biggest tradeoff is charging speed, since a full charge takes about eight hours even though runtime is limited to about 60 minutes.

What Is the Philips Norelco MG3919/50?
The MG3919/50 is part of Philips Norelco’s All-in-One Trimmer 3000 Series. It combines a main trimming blade, fixed-length combs, a nose and ear trimming attachment, charging accessories, cleaning tools, and storage into a compact grooming kit.
The strongest reason to choose it is versatility without complicated controls. Instead of using an adjustable dial, you select a fixed comb for the length you want. The available setup covers very short 0.5mm trimming through 16mm hair cutting, giving you options for stubble, short and medium beards, and basic home hair maintenance.
It is best viewed as an everyday grooming tool rather than a professional clipper. Buyers who need many closely spaced length adjustments, rapid charging, or more specialized body-grooming attachments may prefer a higher-tier system.
Who Should Buy It?
Best For
- You want one kit for beard, stubble, hair, nose, and ear grooming.
- You prefer simple fixed combs instead of a complex adjustable control.
- You normally groom cordless and can charge the trimmer well before you need it.
Skip If
- You need fast charging or several hours of cordless runtime.
- You want very fine length adjustments between every setting.
- You expect a wall power adapter to be included in the box.
Before You Buy: The MG3919/50 needs about eight hours for a full charge and Philips does not include a USB wall adapter. Make sure you already have a compatible 5V USB adapter rated for at least 1A, or plan to obtain one separately.
13 Tools and Accessories: Useful Versatility Without Too Much Complexity
The MG3919/50 is sold as a 13-in-1 grooming system. The useful part is not simply the number on the box, but the range of jobs the included pieces support. You can maintain facial hair, cut head hair at several fixed lengths, clean up very short stubble, and address unwanted nose or ear hair.
The fixed guards also reduce guesswork. Beard combs cover 3mm, 5mm, and 7mm. Hair combs provide 9mm, 12mm, and 16mm lengths. Separate 1mm and 2mm guards handle short stubble, while the uncovered trimming setup provides the shortest approximately 0.5mm length.
The limitation is that these are defined steps. If you frequently want a length such as 4mm, 6mm, or another in-between setting, a trimmer with an adjustable precision comb may suit you better.
Blade Design and Grooming Comfort
Philips uses a self-sharpening, skin-friendly trimming blade with rounded tips on the MG3919/50. Rounded blade tips are designed to make contact gentler than a sharp-edged exposed cutting surface, which is useful when you are working around the face and neck.
The blades do not require routine oiling, reducing one maintenance step. That makes the trimmer easier to own if you want a tool you can clean, dry, store, and use again without maintaining a bottle of blade oil.
No electric trimmer can guarantee irritation-free grooming for every person. Pressure, repeated passes, trimming against the direction of growth, dull or damaged parts, and individual skin sensitivity can all influence comfort. Use light pressure and stop if the trimmer causes persistent pulling or skin irritation.
Length Settings and Precision
The usable trimming range runs from 0.5mm to 16mm. That gives you enough range for close stubble through longer hair, but the MG3919/50 achieves those lengths mainly through separate fixed combs rather than dozens of dial-controlled increments.
For short facial hair, the 1mm and 2mm stubble guards make it easy to maintain a consistent shadow or short beard. The 3mm, 5mm, and 7mm beard guards give you room to build more visible length. The 9mm, 12mm, and 16mm hair combs are better suited to maintaining a simple short haircut or touching up sections between full cuts.
Pro Tip: When you are unsure about beard or hair length, begin with the longest suitable comb. You can always step down to a shorter guard, but you cannot immediately undo a cut that is too short.
Battery Life and Charging
The MG3919/50 uses a rechargeable Ni-MH battery and provides up to 60 minutes of cordless runtime. For normal beard trims or quick touch-ups, that can cover several grooming sessions between charges.
The main compromise is charging speed. A full charge takes about eight hours. That is much slower than the charging systems used by some higher-end trimmers, so this is not ideal if you regularly discover an empty battery minutes before you need to leave home.
A charging LED shows when the unit is connected. Charging uses USB-A power, but Philips does not include the wall adapter. Philips specifies a suitable adapter output of 5V and at least 1A.
Cleaning, Maintenance, and Safety
Philips describes the MG3919/50 attachments as rinseable. Remove the appropriate head or comb, rinse the removable parts as instructed, and let them dry before reassembly. A cleaning brush is also supplied for routine upkeep.
Do not interpret “rinseable attachments” as permission to immerse the complete trimmer in water. Philips distinguishes between washable components and fully showerproof products and advises users to follow the markings and instructions for their exact groomer.
Keeping the cutting area free of loose hair helps maintain consistent performance. Philips also states that the blades do not need oil, so avoid adding lubricants or cleaning chemicals unless the manual specifically instructs you to use them.
How It Performs in Real Use
For Daily Beard Maintenance
The fixed 1mm, 2mm, 3mm, 5mm, and 7mm options make the MG3919/50 particularly useful for repeatable beard maintenance. Once you identify your preferred comb, you can return to the same length without adjusting a dial before every trim.
For Basic Haircuts at Home
The 9mm, 12mm, and 16mm hair combs can handle straightforward short cuts and touch-ups. The selection is much less flexible than a dedicated professional clipper with many guards or a lever, so complicated fades and highly graduated cuts are not this model’s main strength.
For Stubble and Edge Cleanup
The shortest settings work well when you want a close, groomed appearance without switching to a separate razor. You can remove a guard for a roughly 0.5mm trim or use the 1mm and 2mm guards when you want a more even layer of stubble.
For Travel
The included pouch helps keep the loose attachments together, and 60 minutes of runtime can be enough for a short trip if you leave home with the battery charged. The slow eight-hour recharge is the main travel inconvenience, especially if you forget to charge it beforehand.
How to Use the Length Settings for Better Results
Start with dry, detangled hair unless the product instructions for your grooming situation say otherwise. Attach the correct comb firmly before switching the trimmer on. Using the wrong guard is one of the easiest ways to cut significantly shorter than intended.
Move the trimmer steadily rather than pressing hard against your skin. If the hair is long or dense, make several controlled passes and remove trapped hair from the comb when needed. For a beard, beginning with the longer areas before cleaning the neckline and edges can make the final shape easier to judge.
After use, switch the unit off, remove the appropriate attachments, and clean them according to Philips’ instructions. Allow rinsed pieces to dry before putting the kit into its storage pouch.
Pros and Cons
Pros
- 13 tools and accessories cover several everyday grooming jobs.
- 0.5mm to 16mm range works for stubble, beards, and short head hair.
- Self-sharpening, rounded-tip blade requires no routine blade oil.
- Up to 60 minutes of cordless runtime is sufficient for routine trims.
- Rinseable attachments and included cleaning brush simplify maintenance.
Cons
- An eight-hour full charge is slow compared with many premium trimmers.
- Fixed comb sizes give you fewer in-between length choices.
- The USB wall adapter is not included.
Is It Worth the Price?
The MG3919/50 sits in the practical end of the all-in-one grooming market. Its value comes from covering beard trimming, stubble, head hair, and nose or ear grooming without requiring you to buy several separate devices.
It is a strong value if the available fixed comb lengths match the way you normally groom. You also avoid routine blade oiling, and the supplied pouch keeps the small parts together between uses.
The value becomes less compelling if fast charging or very precise length control is a priority. In that case, paying more for a higher Philips series with additional tools, more adjustment options, or longer battery performance may make sense.
How It Compares to Alternatives
The Philips Norelco MG3939/50 is another current 13-in-1 Series 3000 option and is worth comparing if you prefer the full-metal blade configuration offered on that variant. The MG3919/50 instead emphasizes its skin-friendly comfort-blade design.
If you need more accessories and broader grooming capability, a Philips Norelco Series 5000 model such as the MG5910/49 moves up to an 18-piece system and substantially longer cordless runtime. The MG3919/50 makes more sense when you prefer a simpler kit and do not need the added features of the higher series.
Frequently Asked Questions
What model is this Philips Norelco 3000 trimmer?
The Amazon product linked in this review is the Philips Norelco All-in-One Trimmer 3000 Series MG3919/50. It is the 13-piece comfort-blade variant, so specifications from older Multigroom 3000 models should not automatically be applied to it.
What trimming lengths does the MG3919/50 offer?
Its overall trimming range is 0.5mm to 16mm. The kit includes 1mm and 2mm stubble combs, 3mm, 5mm, and 7mm beard combs, and 9mm, 12mm, and 16mm hair combs.
How long does the Philips Norelco MG3919/50 battery last?
Philips rates the rechargeable Ni-MH battery for up to 60 minutes of runtime. Actual time between charges will depend on how long each grooming session lasts.
How long does a full charge take?
A full charge takes about eight hours. Because charging is relatively slow, it is better to recharge the trimmer ahead of time rather than waiting until immediately before you need it.
Does it include a USB wall charger?
No wall power adapter is included. Philips specifies USB-A charging and says a compatible adapter should provide 5V output at 1A or higher.
Can you use the trimmer while it is charging?
Do not assume that you can use it while connected to power. Philips states that most of its groomers cannot operate corded and includes the MG3919/50 among the models covered by that guidance. Follow the instructions supplied with your trimmer and plan on cordless use.
Is the MG3919/50 waterproof?
Philips specifically describes the attachments as rinseable. That is not the same as saying you should immerse the complete appliance, so remove and rinse the appropriate attachments according to the manual rather than submerging the trimmer.
What warranty does the MG3919/50 have?
Philips advertises warranty coverage of up to five years for this model. The longer coverage depends on product registration with Philips within 90 days of purchase and the applicable warranty terms, so register promptly if you want the available extension.
The Bottom Line
The Philips Norelco All-in-One 3000 Series MG3919/50 is a good match if you want an uncomplicated cordless kit for beard, stubble, basic hair trimming, and nose or ear grooming. Its 13-piece setup, 0.5mm to 16mm range, comfortable rounded-tip blade design, and 60-minute runtime are strong everyday features, while the eight-hour charging time and fixed-length comb system are the main compromises.
If those limitations fit your routine, the MG3919/50 is an easy model to recommend with caveats. Buyers who want faster charging, substantially longer runtime, or finer length adjustments should compare a higher-tier grooming system before deciding.
