GUIDE 2026What capacity do I need? What connectors are there? What can I power? Your introduction to mobile energy.
Read the guideA portable power station is a large, rechargeable battery with a built-in inverter. It converts stored energy into 230 V AC power, providing standard household outlets anywhere there is no grid connection.
Unlike a petrol generator, it operates silently, emission-free and can be used indoors. Charge it via wall outlet, solar panel or 12 V car socket.
LFP vs. NMC
Capacity is measured in watt-hours (Wh). Rule of thumb: add up the power draw of all devices you want to run and multiply by the planned usage time.
Phones, camera, drone, LED light. 1--2 days of light camping. Weight: ~3--4 kg.
Cooler, laptop, lights, phone charging. 2--4 days with solar. Weight: ~10--13 kg.
Fridge, coffee maker, power tools, e-bike. Expandable to 4--8 kWh. Weight: ~18--29 kg.
| Device | Power (W) | 1 hr (Wh) | Note |
|---|---|---|---|
| Smartphone charging | 15--25 | 15--25 | ~20 full charges from 500 Wh |
| Laptop charging | 45--100 | 45--100 | USB-C PD recommended |
| LED lights | 5--20 | 5--20 | All night possible |
| Compressor cooler | 30--60 | 15--30 | Compressor cycles on/off |
| CPAP machine | 30--60 | 30--60 | 8 hrs = 240--480 Wh |
| Electric grill | 1,500--2,000 | 1,500--2,000 | 2000W+ station required |
| Coffee maker (pod) | 1,200--1,500 | ~100 | Short runtime per brew |
| Electric kettle | 1,800--2,200 | ~150 | 3--5 min for 1 L |
| Hair dryer | 1,000--2,000 | ~300 | Peak power mode only |
| E-bike battery | 100--180 | 100--180 | Full charge: 400--750 Wh |
| Mini fridge | 50--80 | 25--40 | 24 hrs = 600--960 Wh |
| Power drill / jigsaw | 500--1,200 | Varies | Short bursts, high peak |
| TV (32--55") | 40--120 | 40--120 | Movie night = ~200--400 Wh |
Continuous vs. Peak Power
Compatibility
Cooler, lights, phones, camera. Self-sufficient for days with a solar panel. Compact models (300--800 Wh) cover most trips.
Recommended: 300--1,000 Wh, under 10 kg
A permanently installed power station replaces the auxiliary battery. Benefits: LFP longevity, built-in inverter, app monitoring. Rooftop solar charges while driving.
Recommended: 1,000--2,000 Wh, expandable, UPS function
During a power outage, a UPS-capable station keeps router, NAS and laptop running seamlessly (switchover time 10--20 ms). For a fridge, you need at least 1,000 Wh.
Recommended: 1,000--2,000+ Wh, UPS, expandable
Power tools, PA systems, lighting. For devices above 1,500 W, the station needs at least 2,000 W continuous output.
Recommended: 1,000--2,000 Wh, 2,000+ W AC output
