How Long Will My Power Station Last?

A 1,000Wh power station runs a mini-fridge for about 14 hours, a laptop for 13 hours, or basic camping gear (lights + phones + fan) for 2+ days. Select your exact model and devices below to get a precise runtime estimate.

Tips to Maximize Runtime

Small changes in how you use your power station can stretch runtime by 20-40%.

Use 12V/DC outputs instead of AC when possible

The inverter that converts DC battery power to AC loses 10-15% efficiency. Devices that accept 12V input (coolers, car chargers, LED strips) draw less from the battery when plugged into the DC port.

Lower screen brightness and use eco modes

A TV at 50% brightness draws 30-40% less than at max. Laptops in battery-saver mode drop from 65W to around 30-40W. Every watt saved is runtime gained.

Stagger high-draw devices

Running a coffee maker (900W) and a microwave (1,000W) at the same time pulls 1,900W. Running them back-to-back keeps your peak load lower and avoids tripping the inverter.

Keep the battery between 20% and 80% in storage

LiFePO4 batteries last longest when stored at 50-60% charge. Avoid draining below 10% or leaving it at 100% for weeks. This preserves long-term capacity so your runtime stays consistent over years.

Use timers and smart plugs to cycle devices

Running a fan on a 30-minutes-on, 30-minutes-off cycle halves its energy use. Space heaters on a timer keep a room comfortable while cutting runtime in half compared to continuous use.

Charge during the day with solar panels

A 200W solar panel produces roughly 600-800Wh on a sunny day. For a 1,000Wh station running light loads, that means effectively unlimited runtime during daylight hours, reserving battery for overnight.
