Choosing the Panasonic ER-DGP90 hair clipper: a practical buying guide for precise trimming

Buying a professional hair clipper seems straightforward until you have to choose between cutting lengths, comb attachments, cordless use and maintenance. With the Panasonic ER-DGP90 hair clipper, many shoppers want a tool for precise cutting and trimming, both in the salon and at home.

Yet a few common marketing claims often lead to disappointment. A cordless clipper isn’t automatically suited to long cutting sessions. And a device that looks professional doesn’t always offer the right adjustable cutting length or an easy cleaning method.

Common pitfalls when buying a hair clipper

1. Judging it by the number of accessories alone

A big bundle of comb attachments sounds appealing, but check which lengths you actually get. For fades, shaping and close work, the minimum cutting length matters more than the total number of accessories.

According to the product description, the Panasonic ER-DGP90 has a dial offering lengths from 0.8 to 2.0 mm. You also get four double‑sided comb attachments, taking the range up to 25 mm. That span works for close precision work as well as evenly shortening longer hair.

2. Mistaking cordless for maintenance‑free

A cordless clipper gives you freedom to move, but the battery still needs to be charged and cared for properly. So check whether the unit can also be used on the mains. According to the product information, the Panasonic ER-DGP90 can be charged via the charging stand or plugged in directly with the mains lead.

Pay attention to cleaning, too. The housing on this model is not waterproof. Do not hold the clipper under the tap or immerse it. That’s an important difference from some hair trimmers that are sold as water‑resistant.

3. Taking “professional” at face value

The word professional doesn’t mean much on its own. Look for verifiable details such as the cutting‑length range, what’s in the box, power options and maintenance instructions. For barbers’ clippers it’s also crucial that you can switch lengths quickly and store the device clean and dry.

Which specifications really matter?

Cutting length and adjustment mechanism

A hair clipper with adjustable cutting length is practical when you’re creating different haircuts or beard lines. A dial can be quicker than constantly swapping attachments. Do note the difference between the blade’s adjustable length and the lengths achieved with combs.

On the Panasonic ER-DGP90 you set the blade between 0.8 and 2.0 mm. With the four double‑sided combs, the range extends up to 25 mm. This black clipper is therefore suitable for close cuts, touch‑ups and even trims.

Corded and cordless use

A cordless hair clipper is handy when you’re moving around a chair or want to trim at home without a lead. For intensive use, being able to run it directly from the mains is equally useful. When buying, check:

  • whether a charging stand is included;
  • whether mains‑powered use is possible;
  • how the device should be charged;
  • whether the charging cable and accessories are in the box.

The ER-DGP90 product description lists a charging stand and a mains lead. A specific runtime per charge isn’t provided in the supplied information. If you work through multiple clients back‑to‑back each day, it’s wise to check the latest specifications and availability on the product page.

Maintenance and safety

As per the instructions, the blades should be lubricated with a few drops of the supplied oil before and after every use. Remove hair residue with the cleaning brush and keep the housing dry.

Do not use a hair trimmer or precision clipper if the lead or blades are damaged. Don’t touch moving blades, and charge the device according to the manufacturer’s guidance. According to the product information, the Panasonic ER-DGP90 is covered by at least two years’ statutory warranty in the EU. Additional rights may apply depending on national law.

Using and maintaining the Panasonic ER-DGP90

Fully charge the unit before first use with the charging stand or mains lead. Then select the desired length with the dial, or fit a suitable comb attachment. Work on clean, dry hair and regularly check for hair trapped between the blades.

Clean the blades after every cut with the brush. Apply a few drops of oil before and after use, as stated in the product instructions. Only clean the housing as directed in the manual and keep it away from water. Regular maintenance helps keep the cutting action smooth, but replace blades or parts if they become damaged.

Frequently asked questions about the Panasonic ER-DGP90 hair clipper

Is the Panasonic ER-DGP90 suitable for cordless use?

Yes. According to the product description, the clipper can be charged via a charging stand and then used cordlessly. You can also connect the device directly with the mains lead. The exact battery life isn’t listed in the supplied specifications, so check the current product page for details.

Can I rinse the Panasonic ER-DGP90 under the tap?

No. The main unit is not waterproof and must not be submerged or cleaned under running water. Use the supplied cleaning brush, keep the housing dry and follow the maintenance instructions.

How long does a Panasonic clipper last?

Lifespan depends on how often you use it, cleaning, lubrication and blade condition. With daily salon work, regular maintenance is even more important. Do not use a clipper with damaged blades or a damaged lead. According to the product information, the statutory warranty is at least two years in the EU; this is separate from the practical lifespan of the device.
