Sirius Watts homepage

Buying a power station usually means decoding watt-hours, inverter losses, and conflicting brand claims. Most people either overspend, undersize, or give up and guess.

We built Sirius Watts as a quiet guide: ask what you need to power, do the honest math, then show real gear that fits — with an admin side so the catalog can stay current without drama.

In about a minute, shoppers get a clear recommendation across Jackery, EcoFlow, Bluetti, Anker, and Renogy — plus scenario shortcuts for camping, RV life, home backup, and more.

Inside the build

A look at how the project took shape — the decisions, the work, and what visitors feel when they land.

01

Making the math feel human

The hardest part of this product wasn’t the UI — it was translating battery math into something a tired shopper could trust. We shaped a short flow: tell us your appliances, we’ll estimate capacity and solar with real-world losses included.

Defaults for fridges, CPAPs, laptops, and lights keep the path gentle. Nobody should need a spreadsheet to feel confident.

02

Matching people to real gear

Once the numbers were clear, we connected them to a living catalog — Jackery, EcoFlow, Bluetti, Anker, Renogy — with the details that actually matter: watt-hours, output, weight, and value.

Best fit and best value sit side by side, so the recommendation feels helpful instead of pushy.

03

Shortcuts for how people actually live

Not everyone wants to build a list from scratch. We added calm shortcuts for camping, RV and van life, home backup, CPAP and medical use, and off-grid cabins — little doors into the same honest math.

It’s a way to skip the forum rabbit hole and land somewhere useful sooner.

04

Keeping the catalog honest behind the scenes

Prices and SKUs move. So we built a simple admin side for products, pricing, and recommendations — the quiet machinery that keeps the public tool trustworthy.

That way the calculator can stay useful without a developer ticket every time the market shifts.

05

A soft landing for first-time visitors

No signup wall. Instant results. Clear next steps. Sirius Watts works when it feels like a favor, not a funnel — useful first, conversion second.

Build process

  1. 1

    Discovery

    We scoped the calculator, the loss model, brand coverage, and admin needs for a focused mid-tier build.

  2. 2

    Design

    We sketched a three-step path: appliances → clear numbers → what to buy.

  3. 3

    Build

    Then came the calculator logic, catalog matching, scenario guides, and public UI.

  4. 4

    Admin

    We added product and price management so the catalog could stay fresh.

  5. 5

    Launch

    Copy, SEO basics, and a clean handoff finished the story.
