Backup Power

Backup Power & Solar

A portable power station is sized by what you need to run and for how long. This category covers home-backup stations, solar generators, and compact units for travel. We compare by usable watt-hours, continuous and surge output, battery chemistry, recharge speed, and whether you can expand capacity later — the factors that decide whether it actually carries your fridge through an outage or just tops up phones. As a rough frame, compact units under 500Wh top up phones, laptops, and camp gear; 1-2kWh stations carry a fridge and lights through a shorter outage; 3kWh-plus systems with high continuous output start covering well pumps and larger appliances. The mistake that wastes the most money is buying by capacity alone and under-sizing the output wattage, so the unit holds plenty of energy but trips the moment a motor-driven appliance starts.

Best for

  • Home backup for outages and essential appliances
  • RV, van life, and weekend camping
  • Travel and everyday carry where weight matters

What to compare

  • Capacity (Wh) — Usable watt-hours decide how long it runs your load.
  • Output (W) — Continuous and surge watts decide what you can plug in.
  • Battery chemistry — LiFePO4 lasts far more cycles than older NMC.
  • Recharge speed — Wall and solar input, and full-charge time.
  • Expandability — Whether you can add battery packs later.
