Stay connected during a power outage at home
A silent, portable backup power supply for phone, Wi-Fi, lighting, fridge and more — no fuel, safe for indoor use. From a compact personal emergency kit to a complete 3000Wh solar generator.
Why home backup power is becoming essential
During a prolonged power outage, daily essentials fail quickly. Governments recommend households be prepared to be self-sufficient for at least the first 72 hours of an emergency. A Mobisun powerstation goes beyond a power bank — it can power multiple devices for an extended period.
Which devices do you want to keep running?
The backup power supply you need depends on the wattage of your devices and how long you want to run them.
📱 Communication and information
Stay reachable and receive important updates.
- Smartphone and tablet
- Wi-Fi router and modem
- Laptop and radio
- Starlink Mini
- Walkie-talkie
💡 Lighting and small devices
Essential lighting and small electronics.
- LED lighting
- Chargers
- Television
- Security cameras
- 12V devices
❄️ Coolbox, fridge and freezer
Compressor coolboxes draw relatively little power; kitchen fridges have a high startup surge.
- Compressor coolbox: Pro Air / Classic / Air 2.0
- Kitchen fridge: high startup surge
- Freezer: high startup surge
🩺 Medical equipment
Pure sine wave output is suitable for sensitive electronics like CPAP.
- CPAP machines
- Other sensitive electronics

How long does a powerstation provide backup power?
Usable battery capacity in Wh ÷ device wattage = runtime in hours. Expect about 85% of the nominal capacity in practice.
Example with the Mobisun Pro Air 2.0 (~262Wh usable):
These are estimates. Actual runtime depends on consumption, startup surge, temperature, battery state, cable losses and simultaneous use of other devices.
Stay independent longer with a solar panel
During a prolonged outage, a solar panel can significantly extend your runtime. During the day you recharge the battery.
How to build a practical backup power plan
Seven steps toward robust preparation for a power outage.
Determine what's truly essential
List devices that must keep working: communication, lighting, information, medical or cooling equipment.
Note the wattage
Check the type plate or adapter. Note the normal wattage and, where relevant, the surge or startup wattage.
Calculate required capacity
Multiply consumption in watts by the desired runtime hours. Add everything up and account for ~15% conversion loss.
Choose sufficient surge capacity
A battery may have enough capacity but still shut down if a device draws more power at startup than the inverter can deliver.
Add solar charging
A suitable solar panel lets you generate new energy during a prolonged outage.
Test your setup in advance
Don't wait until the power actually goes out. Connect your most important devices beforehand and verify real runtime.
Keep the battery charged
Check the charge status regularly and recharge periodically according to the manual's instructions.
Portable backup power or fixed home battery?
Both options have their own use case. Understand the difference before you choose.
🔋 Mobisun powerstation (portable)
- Connect devices directly to the powerstation
- No permanent installation or renovation needed
- Ready to use, also outdoors
- Rechargeable with solar and grid power
🏠 Fixed home battery
- Permanently connected to the electrical installation
- Often paired with solar panels
- Does not automatically work when the grid fails (often requires separate backup)
- Requires installation by a qualified installer
