Direct Answer
The Panasonic ER-GB70-S is an AC/rechargeable beard and hair trimmer with two combs: 1-10 mm for beard and 11-20 mm for hair. It also has a precision trimmer for narrow lines and detail work. Choose the correct comb before setting the dial, trim dry hair as the manual directs, remove collected hair, and clean and oil the blade after use.
What the ER-GB70-S Kit Is For
Panasonic’s official ER-GB60/70/80 operating instructions identify ER-GB70 as a beard and hair model with a built-in precision trimmer. It shares a platform with ER-GB80 but does not include the ER-GB80 body-hair comb.
The page is therefore organized around two length zones and detail trimming. Verify the S suffix, regional adapter, pouch, brush, oil, and both combs on the exact package.
Two-Comb Length Map
| Attachment | Documented range | Primary task |
|---|---|---|
| Beard comb | 1-10 mm | Stubble, moustache, and beard length control |
| Hair comb | 11-20 mm | Longer hair and bulk reduction |
| No comb | Approximately 0.5 mm boundary | Controlled shaping and downy hair |
| Precision trimmer | Unguided detail blade | Narrow lines, moustache ends, and edges |
Fit the selected comb with the unit switched off, then turn the dial to a valid setting for that attachment. The length chart helps plan targets; the guard guide explains why comb range and dial setting must be considered together.
Precision Trimmer Use
Remove the comb and slide the precision trimmer fully into position. Panasonic documents it for narrow areas and detailed trimming around moustache ends, sideburns, and beard lines. It is not a substitute for the guarded blade when preserving bulk. Keep movements short and visible, and avoid repeatedly raising an edge while trying to make it sharper.
Use the beard-shaping guide to plan lines before removing length. A precision blade executes the boundary; it does not choose the best boundary for a face.
Charging and Operating Checks
Panasonic documents approximately one hour for a full charge and approximately 50 minutes of use under stated conditions for this family. Those are reference values, not guarantees for an aged battery. Match the adapter model, voltage, product socket, and regional manual, then confirm that the charge lamp behaves as described.
The platform supports AC/rechargeable operation, but never connect power during washing or in a wet location. If the unit was stored for months, follow Panasonic’s extended first-charge guidance rather than assuming immediate battery failure. See the power-format guide for general context.
Beard and Hair Workflow
- Choose beard or hair attachment before touching the dial.
- Start at a longer valid setting and work against dry hair growth.
- Clear collected hair from inside the comb during bulk removal.
- Cross-check both sides and the back before moving shorter.
- Remove the comb only for planned shaping or precision-trimmer work.
- Clean, dry, oil, and store all components separately after use.
Cleaning and Blade Maintenance
Disconnect the adapter. Panasonic permits a light-dirt water-inlet method and a removed-blade method for heavier cleaning. Follow the manual’s sequence, shake off water without striking the sink, towel the body, and let the blade area dry naturally. Apply oil at the marked points before and after use as instructed.
The maintenance guide supplements but does not replace Panasonic’s model-specific procedure.
Used-Kit Verification
- Both beard and hair combs are present and undamaged.
- The precision trimmer slides fully and stays in position.
- The dial, blade, water inlet, socket, and switch work correctly.
- The adapter matches the label and charge lamp behavior.
- Battery runtime is demonstrated without treating it as guaranteed.
- Cleaning brush, oil, pouch, condition, and return terms are recorded.

Frequently Asked Questions
Can ER-GB70-S trim body hair?
Panasonic’s family manual assigns the dedicated body comb to ER-GB80. Do not treat ER-GB70 as the same body-grooming kit.
Can one comb cover 1-20 mm?
No. The documented kit uses a 1-10 mm beard comb and a separate 11-20 mm hair comb.
Is wet beard trimming recommended?
The cited manual instructs beard trimming without shaving foam and warns that wet beard hair can stick or bunch. Follow the exact regional instructions.
