PowerStationSelect
Power Station Recommendation Engine
A decision-support tool that calculates energy requirements and recommends suitable portable power stations based on real usage scenarios.
PowerStationSelect helps people translate a real usage scenario into understandable energy requirements and suitable portable power station options.
Problem
Comparing battery capacity, device consumption and usage time is difficult when product specifications are presented without the context of a person's needs.
Constraints
- Energy and instantaneous power are separate physical constraints.
- Unknown surge capability must remain unknown, not become zero.
- Static typed data and pure functions are intentional for this version.
Solution
A guided decision tool that models the scenario, calculates requirements and turns the result into a clearer recommendation.
The technical layers that turn the product idea into a working system.
Physical model
Pure functions calculate energy, autonomy, capacity, power, surge and runtime.
Compatibility
Energy, continuous output and nullable surge are checked before ranking.
Catalog systems
25 active products, five brands and nine expansion references form the typed catalog.
Recommendation
Technical compatibility, actionability and recommended fit stay separate.
Select a node to inspect its role and relationships.
Physical inputs become a technically compatible recommendation.
Separate energy from power
- Context
- Duty cycle changes consumption, not instantaneous demand.
- Decision
- Model dailyWh and running/start power independently.
- Trade-off
- The model carries distinct compatibility constraints.
- Revisit when
- If the physical model changes.
PSS-INC-01Unknown surge semanticsResolved
- Symptom
- Unknown capability could be read as zero or incompatibility.
- Root cause
- The unknown state was not explicit enough.
- Fix / mitigation
- Preserved nullable surgeOutputW through compatibility.
- Lesson
- Unknown technical data needs explicit semantics.
- Status
- Resolved
PSS-INC-02Duplicated surge policyResolved
- Symptom
- Calculation paths could disagree.
- Root cause
- Surge rules existed in duplicated paths.
- Fix / mitigation
- Replaced them with one canonical policy.
- Lesson
- Technical rules need one source of truth.
- Status
- Resolved
PSS-INC-03Naive modular combinationsResolved
- Symptom
- A parseable configuration could be technically invalid.
- Root cause
- Parsing did not encode expansion rules.
- Fix / mitigation
- Separated parsing from buildValidatedSystem validation.
- Lesson
- Syntactically valid is not technically valid.
- Status
- Resolved
- Physical semantics belong in the data model.
- Compatibility, recommendation and actionability are different decisions.
- Calibration scenarios are references, not universal advice.
- Authorized product imagery and assets.
- Affiliate links/feeds and commercial snapshot refresh.
- Additional SEO work.
