The Geimori T38 Plus is a compact plug-in single-dose coffee grinder designed to cover fine espresso settings as well as everyday filter brewing. To understand how it performs outside the product specification sheet, we reviewed nine creator videos covering espresso, pour-over, grind adjustment, workflow, build quality, portability and value.
Across the videos, the strongest recurring themes are the grinder’s unusually compact footprint, metal construction, precise stepless adjustment and ability to grind finely enough for home espresso. The main trade-offs are equally clear: the T38 Plus requires mains power, does not shut itself off automatically and still benefits from bellows use when clearing retained grounds.

What Is the Geimori T38 Plus?
The T38 Plus is a compact electric single-dose grinder using a 38 mm six-axis conical burr set. Grind size is controlled through a continuous stepless adjustment collar, allowing small changes when dialing in espresso instead of forcing the user to move between fixed clicks.
Unlike the battery-powered T38, the T38 Plus operates from an external AC-DC adapter. That gives it stable plug-in power and a higher grinding speed, but it also means the grinder cannot be used away from an outlet.
| Burr set | 38 mm six-axis conical burrs |
|---|---|
| Grind adjustment | Stepless adjustment from fine espresso to coarse brewing |
| Grinding speed | Approximately 190 RPM |
| Power source | External AC-DC plug-in adapter |
| Input voltage | 100–240V AC, 50/60Hz |
| Hopper capacity | Approximately 30 g |
| Product weight | Approximately 1.23 kg |
| Recommended use | Home espresso, filter coffee, offices, hotel rooms and compact plug-in coffee stations |
Espresso Performance
The central question for a grinder of this size is whether it can grind finely enough for an unpressurized espresso basket. Multiple videos in the playlist specifically demonstrate espresso dialing and extraction, and the overall evidence indicates that the grinder has sufficient adjustment range for home espresso.
Stepless adjustment is particularly useful here. A small movement of the collar can change shot flow without forcing the user to jump between widely spaced settings. That provides more control, but it also means owners should record their preferred numbers for each coffee.
The 38 mm conical burr profile is likely to appeal most to users who enjoy rounded sweetness, body and traditional espresso texture. Buyers prioritizing maximum separation and clarity from very light roasts may eventually prefer a larger flat-burr grinder.
Filter Coffee and All-Purpose Use
The T38 Plus can move beyond espresso into AeroPress, pour-over, drip, French press and cold-brew settings. This broad range makes it more versatile than an espresso-only grinder.
The main issue is not whether it can reach those settings, but how often the user plans to switch between them. Moving from a very fine espresso setting to a coarse filter setting requires several turns and makes it helpful to save reference positions.
Users brewing large filter batches should also consider capacity and speed. The T38 Plus is built primarily around single-dose home brewing rather than high-volume batch grinding.
Build Quality and Countertop Footprint
Compact dimensions are one of the grinder’s clearest advantages. It occupies much less counter space than most dedicated electric espresso grinders and can fit easily beside a compact espresso machine, on an office shelf or inside a travel case.
The metal exterior and wooden accents give it a more substantial appearance than entry-level plastic grinders. The magnetic dosing cup also helps create a tidy, repeatable workflow beneath the chute.
The external power adapter is the less elegant part of the design. Although the grinder itself is small, the adapter adds bulk on the counter and needs to be packed whenever the grinder is transported.
Noise, Speed and Daily Workflow
Reviewers generally characterize the motor sound as relatively restrained and lower-pitched. This is useful for early-morning home brewing, offices and shared spaces.
The workflow is straightforward: weigh a dose, add the beans, start the motor, allow the coffee to pass through, use the bellows and then manually switch the grinder off. There is no automatic shut-off, so the motor continues running until the user presses the power button again.
Retention and Static
The T38 Plus includes an anti-static system and a short single-dose pathway intended to reduce coffee scattering and retained grounds. The included bellows can help clear coffee remaining around the burr chamber and chute.
Low retention should not be interpreted as guaranteed zero retention. Results can change with grind size, roast level, bean moisture, dose, seasoning and cleaning frequency. Fine espresso grinding will generally leave more particles inside the chamber than a coarser setting.
A light RDT spray before grinding, followed by one or two controlled bellows presses after grinding, can help improve cleanliness and dose recovery.
Is the T38 Plus a True Travel Grinder?
Physically, yes: the grinder is small enough to pack and carry between locations. Electrically, no: it is not cordless and must be connected to its AC-DC adapter.
It is therefore best described as a portable-size plug-in grinder. It works well for hotel rooms, offices, RVs, holiday rentals and locations where a suitable outlet is available. For off-grid camping or genuinely cordless use, the battery-powered T38 is the more appropriate model.
T38 Plus vs. T38
| Feature | T38 Plus | T38 |
|---|---|---|
| Power source | External plug-in adapter | Built-in rechargeable battery |
| Best setting | Home, office, hotel or powered travel setup | Camping, commuting and cordless travel |
| Grinding speed | Approximately 190 RPM | Approximately 50 RPM |
| Main advantage | Stable power and faster daily grinding | True cordless convenience |
| Main compromise | Requires adapter and electrical outlet | Slower grinding and battery management |
Geimori T38 Plus Pros and Cons
What Stands Out
- Very compact footprint for an espresso-capable grinder.
- Stepless adjustment supports small dialing changes.
- 38 mm conical burrs cover espresso and filter ranges.
- Metal construction feels more substantial than basic grinders.
- Relatively quiet operation for home and office use.
- Magnetic dosing cup helps simplify the workflow.
- Anti-static system helps reduce scattered grounds.
- 100–240V adapter supports use across multiple regions.
What to Consider
- It is not battery-powered or truly cordless.
- The external power brick adds travel and storage bulk.
- The motor does not shut itself off automatically.
- Bellows use remains part of the normal workflow.
- Stepless settings can be difficult to relocate without notes.
- It is designed for single doses rather than large batches.
- Very light-roast espresso can place greater demand on a small motor.
- Low retention does not mean absolutely no retained coffee.
Who Should Buy the T38 Plus?
The T38 Plus is most suitable for:
- Home baristas with limited countertop space.
- Espresso drinkers who want precise stepless adjustment.
- Users who also prepare pour-over, AeroPress or French press.
- Small apartments, offices and compact coffee bars.
- Travelers who expect access to a suitable electrical outlet.
- Buyers moving beyond a blade grinder or basic stepped grinder.
It may be less suitable for:
- Off-grid camping and locations without mains electricity.
- Users who require automatic timed dosing or auto shut-off.
- High-volume cafés or shared commercial environments.
- People who regularly grind large filter batches.
- Buyers expecting completely retention-free operation.
- Users prioritizing maximum light-roast clarity from large flat burrs.
Final Verdict
Taken together, the nine videos present the Geimori T38 Plus as a capable compact grinder rather than a novelty travel appliance. Its strongest argument is that it combines espresso-level grind adjustment, broad brewing range and solid construction in a body that takes up very little space.
The compromises are mostly related to workflow. It requires mains power, the external adapter is relatively bulky, the motor must be stopped manually and bellows use helps achieve the cleanest dose transfer.
For a home barista who wants a small, quiet and flexible single-dose grinder for espresso and everyday filter brewing, the T38 Plus offers a convincing balance of size, control and value. For users who need genuine cordless operation, the standard T38 remains the better fit.
