Tips
- • Wattage labels on devices are maximum draw — actual use is usually less.
- • Motor-driven appliances (fridges, AC) have a startup surge 2–3× their running watts.
- • LiFePO4 batteries support more cycles and deeper discharge than standard Li-ion.
- • For solar recharging, divide your required Wh by peak sun hours in your region.
