The Verdict
The Panasonic ER-GB80 is a wet dry beard trimmer with 39 length settings, aiming for even results on both stubble and fuller beards. It fits the Best Wet Dry slot, but expect gradual blade dulling and some battery fade as it ages, so replacements may be part of long-term ownership.
Who it's for: People who groom in the shower or prefer to rinse the blades, and who want many length steps. You accept that performance may drift with time as the battery weakens and blades dull.
Who should skip it: Buyers who want a trimmer that stays sharp and strong for many years with no upkeep. If you hate retouching or notice cut quality dropping early, look for a higher durability option.
In-Depth Review
Performance
With a Performance score of 7.8, the Panasonic ER-GB80 lands in the "Smooth, reliable trimming" range. In day to day use, it cuts beard hair evenly when you keep the guard flat and move at a steady pace. The stainless steel blade is designed for regular grooming, and that matters for consistency across different beard zones.
You also get 39 precision length settings. That is a lot of granular control for shaping stubble to shorter beards. It helps you avoid the common problem of jumping from “too short” to “too long.” For many users, that translates into cleaner lines at the jaw and cheek areas.
For coarse hair, expect the kind of results that stay smooth early on, then get less sharp as days turn into weeks. The listed downside is "Gradual blade dulling," which fits the real-world pattern of home trimmers. The clipper still does the job, but it can require slower passes to avoid patchiness after the blade loses edge.
Battery
Panasonic scores 8.3 on Battery, which maps best to "Consistent power all session." The ER-GB80 runs for up to 50 minutes on cordless power. That is enough for a full at-home routine on most faces, including trimming and light cleanup.
It also supports both cordless and corded use. The power source is listed as Corded/Cordless. That matters because it reduces pressure to rush when the battery nears empty. You can keep grooming through longer sessions without stopping mid blend.
Still, Panasonic lists "Battery fade over time" as a drawback. That usually shows up after long term use, not on day one. The main trade-off here is that the 50 minute runtime is strong, but battery aging can reduce the benefit of cordless freedom later.
Build
With a Build score of 7.7, this sits closer to "Sturdy feel, sharp blades" than “flimsy.” The blade is stainless steel. That type of blade material typically holds up well under frequent trimming, and Panasonic even describes a replacement blade as forged in Japan from hypoallergenic stainless steel.
The ER-GB80 also supports Wet/Dry use. Washable wet trimming changes the maintenance pattern. You rinse or clean after a session, and the unit has to keep working even when you use it in water based routines. Over time, consistent wet cleaning can stress housings and internal parts on any trimmer. The existing pro side is that the wet/dry approach supports easier cleaning.
The downside list includes "Gradual blade dulling." When blades dull, you feel it in the build too. The trimmer can start to tug more during passes, even if the motor and housing remain solid. For long term ownership, blade wear becomes the biggest build related variable.
Features
Panasonic scores 8.1 on Features, aligning with "Useful extras for precision." The ER-GB80 gives you 39 length settings using a trim length dial and guard attachments. That range is practical for both short stubble and longer beard outlines, since you can dial in fine changes instead of relying on only a few guard sizes.
Wet/Dry use is another key feature detail. If you like shaving-cream style cleanup, or you prefer rinsing the blades after trimming, this design fits that routine. The wet/dry versatility is listed as a pro, and the wet/dry use spec confirms it is made for that type of cleaning.
Cordless freedom is listed as a pro as well, and the specs back it with cordless operation plus a stated 50 min runtime. Together, these features help you maintain control of both the detail work and the messy parts of a beard routine without needing a sink nearby.
Value
The Value score is 7.9, which best matches "Strong value overall." The ER-GB80 combines a long 50 min runtime with 39 settings, and it supports wet/dry trimming. Those are the elements most people feel every time they groom.
It also uses stainless steel blades, which matters for day to day cutting performance and for replacement availability over time. The model is clearly aimed at routine beard shaping, not just one quick cut. The 39 length steps give you repeatable results when you return to the same style each week.
Even with that positive mix, the cons remain real. "Gradual blade dulling" affects long term cutting comfort, and "Battery fade over time" can reduce the cordless runtime benefit later. Based on the pillar scores, the trimmer is a strong overall pick in the Best Wet Dry category, but it is not a set and forget device if you plan to use it heavily for years.
Frequently Asked Questions
How long does the Panasonic ER-GB80 run on a full charge?
The Panasonic ER-GB80 lists a runtime of 50 minutes. In real use, you should expect that to cover a full beard session for most people. Like most lithium-ion trimmers, performance can feel less strong as the battery ages.
Is the Panasonic ER-GB80 wet and dry usable for shaving in the shower?
Yes, it supports wet/dry use. That means you can use it with or without water, depending on your routine. The main benefit is easier cleanup if you trim while rinsing the blades.
How many length settings does the ER-GB80 have and what range does it cover?
It includes 39 length settings. More settings usually help when you want small changes from day to day, like going from stubble to a short full beard. If you want exact length increments in millimeters, check the included guard markings because the review spec only confirms the count.
What blade material does the ER-GB80 use?
The blades are made from stainless steel. Stainless steel typically holds up well to daily use and cleaning. You will still need to maintain the cutting edge, since any trimmer can start feeling less sharp over time.
Does the ER-GB80 handle thick or coarse beards without pulling?
In practice, the ER-GB80 should do well with regular beard thickness, helped by its stainless steel blades. That said, pulling or uneven patches can show up if you try to cut too much length at once. For thick growth, use smaller passes and let the guards do the work.
My ER-GB80 blades feel dull after months. How do I slow blade dulling and what maintenance helps?
Blade dulling can happen gradually, even with stainless steel blades, especially if you trim dry buildup often. Clean the trimmer after use and keep hair from drying on the cutting head, since residue can increase drag. If you notice battery fade over time too, replacing your charging habits and fully draining occasionally can help, but it will not stop wear on the blades.
Final Verdict
Panasonic ER-GB80 is a strong wet dry trimmer for people who want easy grooming in the sink and solid length control. It cuts smoothly and includes more length options than many rivals, which helps with even results across short to medium beards. The main tradeoff is blade dulling over time, plus some battery fade as it ages.
If you want reliable cordless trimming and you plan to wash it regularly, this is a sound pick. Just expect maintenance and sharper performance to depend on blade care.
