Technical buying checklist
25 bar portable coffee machines: what wholesalers should verify
A buyer checklist for assessing published pressure, battery, charging, adapters, cup format, documentation and repeat-order consistency before placing an order.
1. Treat 25 bar as one line in a wider specification
The current TK Classic portable espresso range lists a 25 bar extraction platform, but a wholesale decision should not be based on pressure alone. The relevant comparison also includes battery capacity, heating time, charging format, cup size, machine dimensions and the supported coffee adapters.
Use the exact product page for the model under review. Similar silhouettes do not mean identical batteries, charging times, cups or included components.
2. Verify the power and heating workflow
Ask the supplier to identify the battery and charging specification for the selected model, then check it against the target use case. A travel product, a gift set and a retail demonstration unit can place different demands on charging time and heated-cup output.
During sample review, document the charger requirement, operating sequence and the exact sample configuration. Do not transfer a result from one model or battery option to another without confirmation.
3. Confirm the coffee format and serving system
Adapter compatibility changes the buyer proposition. DQ-001 supports Nespresso, ground coffee and Dolce Gusto formats; DQ-010 includes an American drip option; other models have their own published configurations. The order brief should name the required adapters rather than use a broad phrase such as ‘capsule compatible.’
- Coffee format and adapter names
- Cup size and single- or double-cup presentation
- Accessories included in the retail box
- Optional accessories offered as a separate bundle
4. Build a repeat-order reference
For repeat wholesale orders, retain the approved sample reference, artwork version, packaging structure and accessory list. The aim is to reduce ambiguity when the same SKU is reordered or localized for another market.
Compliance files, labels and manuals should be reviewed for the destination market. TK Classic provides available certification documents after inquiry; buyers should confirm which files apply to the selected model and market before order approval.
Compare only model-specific information.

Questions buyers ask before approval
Does 25 bar guarantee the same result across every model?
No. Pressure is one specification. Battery, heating, coffee format, cup design, operating sequence and the approved configuration also need to be reviewed.
Should a buyer compare models from marketing images alone?
No. Use the published model page and approved sample because similar product shapes can have different specifications and included components.
Which documents should a European buyer request?
Request the available model- and market-specific compliance set. The current evidence library includes CE, RoHS, FCC, UKCA, LFGB, FDA, ISO 9001 and EU conformity documents.
