Evening
The power is offfor 4 h
Schedule: 4 h without power, 4 h with power. For a family of three the engine counts what comes next.
What runs
5 device groups —0.42 kWh
Fridge, router, lamps, chargers and laptops use 0.42 kWh in one outage window.
Backup
Portable power stationlasts ~4 h
The engine suggests: Portable power station, 428 W, 0.70 kWh. The outage window is covered.
Power is back
Recharge —0.2 h of 4
The battery recharges while the power is on — otherwise the engine would warn.
Heat
The boiler — counted.Degrees — not.
A gas boiler on backup: 0.81 kWh per window. How warm the flat stays without heating — the engines have no rules, so we promise nothing.
Your bank
Help nearby —no bridges
In the sample directory the left bank has providers in 3 of 6 categories, the right bank in 3 of 6. No routes across the river.
Calmly
Bridges and alerts —in official sources
Data under review
Size your own flat
The provider directory is a fictional citygen sample that shows how search on your own bank works: these providers and addresses do not exist. The real directory is kept by an operator — every fact with a source and date.
A concept, not a design: how backup is wired to the panel, boiler or hob is decided by a licensed electrician from the equipment datasheets. Class prices are indicative ranges, not a price list.
Neutral — and how we make money
- Backup classes — no brands, no partners, in the engine's order: fit first, then price.
- Providers: your bank and your needs first, then proximity, then name. Listing fees do not affect the order — the directory does not even store them.
- No ratings, reviews or “guarantees”.
- No partners are connected yet: the “Get offers” button is inactive.
Partners are not connected yet. When they are: neutral order, your contacts go only to the partner you name and only with your consent. How we make money
