Founder-built product
PowerPreflight
A founder-built product translating equipment loads, backup-power needs, sizing, runtime, and assumptions into an accessible interactive planning experience.
Overview
PowerPreflight helps you estimate backup power needs before you buy equipment. Its calculators cover battery runtime, power-station sizing, solar recharge, and multi-device load building, with a gear-finder wizard for people who would rather answer questions than enter numbers. Around the tools sit buying guides for generators, refrigerators, hurricane prep, food safety, and backup internet, plus use-case picks like Starlink backup, CPAP, and sump pumps, comparisons of power stations versus UPS units versus power banks, and a device wattage library.
The problem it addresses is familiar if you have ever shopped for backup power. The products are sold in watt-hours and inverter ratings, but buyers think in devices and hours: if your office loses power, the question is which devices keep a client call alive and for how long. That gap usually gets filled by whoever is doing the selling, and the easy answer is always a bigger unit.
PowerPreflight takes the opposite approach. It publishes the formulas behind its calculators, labels every result as an estimate, and tells you to verify manufacturer specs before spending money. It discloses that some links may earn commissions, and its recommendations aim at right-sizing rather than upselling: the unit that fits your load, not the most expensive one that plausibly might.
It is a founder-built product by Michael Rodriguez, carried from research through design, build, and launch. It appears here because it shows the working method Volerin applies to client engagements: translate a technical system into plain language, state your assumptions, and size the recommendation to the actual need.

How it was built
Start from the buying decision
Research began with the decisions people actually face: will this power station run a refrigerator through a two-day outage, can it keep a CPAP going overnight, what does a sump pump draw when it kicks on. The calculators, guides, and wizard were shaped around those questions rather than around product categories or brand lines.
Interactive calculation, not static advice
Runtime, sizing, solar recharge, and multi-device loads are live calculators: you enter your devices and constraints, and the tool does the arithmetic in front of you. A gear-finder wizard walks the same logic conversationally for people who do not want to start from numbers. A static table cannot reflect your situation; a calculator can.
Published formulas and labeled estimates
Every calculation shows the formula behind it, and every output is labeled as an estimate rather than presented as fact. Users are told to verify manufacturer specs before buying. Where a result depends on an assumption, the assumption is stated, so a careful reader can check the work.
Plain-language recommendations
Watt-hours, inverter ratings, surge versus running watts: each gets translated into words a non-engineer can act on. The goal is that you finish a page knowing what to do next, not holding a vocabulary list.
Education alongside the tools
The calculators are surrounded by teaching material: buying guides for generators, refrigerators, hurricane prep, food safety, and backup internet; use-case picks for Starlink backup, CPAP, and sump pumps; a comparison of power stations, UPS units, and power banks; and a device wattage library. Someone who arrives knowing nothing can leave understanding the category, not just holding a product name.
Right-sizing over upselling
The site discloses that some links may earn commissions, then works against the incentive that disclosure implies. Recommendations aim at the unit that fits your load, not the largest one available. Telling someone a smaller, cheaper option covers their need is the design principle, not the exception.
Test, iterate, ship
Calculators were exercised against realistic device loads and edge cases, and wording was revised wherever testing surfaced confusion. The result launched as a finished product, with its own domain, structured guides, disclosures, and a wattage library, and it is maintained as a live site.
Why this matters to your project
What this demonstrates
Plain-language technical translation
The core skill on display is the one Volerin sells: understanding a technical system well enough to explain it simply, then actually explaining it simply. Whether the subject is inverter ratings or the lead-routing rules buried in your CRM, the work is the same. A GTM Workflow Audit is this discipline pointed at your pipeline instead of a battery bank.
Estimates labeled as estimates
PowerPreflight never dresses a calculation up as a promise, and Volerin runs client work the same way: no guaranteed outcomes, assumptions written down, estimates labeled as what they are. That is also why Volerin's trust line reads "AI-accelerated. Human-verified." The tools move fast; a person stands behind what ships.
Right-sizing as a commercial rule
The editorial rule on PowerPreflight, recommend what fits rather than what is biggest, is Volerin's commercial rule too. Services are fixed-scope with published prices, so you can buy a $750 audit without being walked toward a retainer. Managed Systems is offered to existing clients only for the same reason: ongoing work should follow demonstrated fit, not precede it.
End-to-end execution by one accountable person
Research, design, build, and launch were done by Michael Rodriguez, and the product shipped as a live site with real disclosures, not as a demo. Volerin engagements run on the same footing: defined deliverables, a stated timeline, and a delivery clock that starts when all required inputs are received.
PowerPreflight is a founder-built product by Michael Rodriguez. It was not paid client work, and no client results are implied; Volerin is a new practice, and this page shows working method rather than client outcomes.
