Apartment backup
Planning six hours of apartment backup power
Six hours without mains power is a clear problem. A “six-hour station” is not a clear solution: a laptop and a fridge use that time differently. Start by breaking the evening into tasks.

Quick answer
Six-hour backup must refer to a specific device list. Internet and a laptop may need much less energy than the same set plus refrigeration. Include a charge reserve, losses and station idle draw instead of multiplying appliance watts by time alone.

Fictional household scenario · not a customer account
When this becomes a household question
Imagine working from home with a few hours left in the shift, followed by an evening needing lights and internet. The laptop can spend part of that time on its own battery. Counting every device as a continuous six-hour station load can double-count some energy and inflate the purchase.
Sketch the evening hour by hour
Mark work, dinner and the time before bed. The router may be needed throughout, the laptop for part of the period and lights only after dusk. A fridge has its own cycle. Do not squeeze these different tasks into one imaginary continuous appliance. A timeline shows where savings are possible without much loss of comfort.
Include the station’s own consumption
Battery energy does not all reach the appliances. Conversion uses some, the station itself uses some and you may deliberately keep a reserve. With a small router load, those extras can matter. The worked example states its assumptions so you can replace them with information relevant to your setup.
A worked example with explicit assumptions
This is an illustrative scenario, not a measurement of your appliances: 1,024 Wh capacity, 10% reserve, assumed 85% efficiency and 8 W idle draw. A 96 W average load gives approximately 7.62 hours. For a 6-hour target, the calculated nominal capacity is about 806.27 Wh. Startup demand and output limits require a separate check; this calculation does not establish compatibility.
| Device | Running W | Quantity | Duty cycle |
|---|---|---|---|
| Laptop | 60 | 1 | 100% |
| Router and ONT | 20 | 1 | 100% |
| LED lights | 8 | 2 | 100% |
Check what happens after hour six
When mains power returns, you may need to work while the station recharges. Check the supported mode, charging input and time until the next outage. Extra capacity helps only if you can replenish it. Also verify simultaneous load and fridge startup; a runtime calculation does not cover those checks.
Before you decide
- Define the exact six-hour device set.
- Account for the recharge interval.
- Leave margin for changes in the plan.
Common questions
Is 1024 Wh enough for six hours?
The illustrative scenario calculates sufficient energy. Different appliances and losses require a new calculation.
Can energy saving add two more hours?
Possibly, if average load falls. Recalculate rather than adding an arbitrary number of hours.
