The 1 kWh class is the most popular compromise between capacity, weight and price – big enough for a fridge and coffee machine, yet still portable.

The all-rounder class

Power stations between 1,000 and 2,000 Wh usually offer 1,500 to 2,400 W of continuous output. That means power-hungry appliances such as kettles, microwaves or air fryers will run too – but only briefly, because they drain the battery quickly. Their strength lies in powering medium loads for many hours: a compressor fridge in a motorhome, lighting, laptop, router or pumps.

Weighing around 10 to 20 kg, these units can still be carried by one person. Many models can be expanded to double the capacity or more with extra batteries, so you can start with a medium size and upgrade later.

What matters in this class

Because many units have similar capacities, the details make the difference.

  • Continuous and peak output: high peak output is important for fridges and tools; some units have a mode that runs resistive loads at reduced voltage.
  • Mains charging time: fast charging fills 1 kWh in under an hour in some cases – handy when a power cut is forecast.
  • Solar input: 500 W or more lets you recharge almost completely on sunny days.
  • UPS switchover time: values below 20 ms are enough for most PCs and routers.
  • App control via Wi-Fi or Bluetooth shows consumption and remaining runtime.
  • Expansion port for extra batteries and compatible accessories.

Worked example: motorhome

Assumptions: compressor fridge averaging 40 W, lighting and phone charging together 20 W over six hours, laptop 50 W over three hours. That adds up to roughly 960 Wh + 120 Wh + 150 Wh per day, so around 1,230 Wh. With a 1,500 Wh power station (roughly 1,250 Wh usable after losses), you can manage about one day; with a 200 to 400 W solar panel, self-sufficiency on sunny days increases considerably. All figures are example assumptions – your consumption may differ significantly.

Price per watt-hour as a benchmark

Offers vary widely in this class. Divide the price by the capacity to compare the price per Wh – but only for units with comparable features. A unit with fast mains charging, high solar input and a UPS function can justifiably cost a little more per Wh than a basic model. The price history shows you whether a deal really is good value.
