Understanding Your Result
The calculator adds a 20% buffer to account for real-world efficiency losses. LiFePO4 power stations typically retain about 90% usable capacity, and devices often draw slightly more than their rated wattage. The buffer ensures your power station handles real conditions, not just perfect conditions.
