Pro Tips

  • UPS units are rated in VA (volt-amps), not watts โ€” multiply VA by 0.6 to get usable watts
  • Power banks lose 20-30% of capacity over 2 years โ€” replace every 3-4 years
  • A UPS protects against both outages and power surges โ€” computers need both
  • Solar chargers work best as a trickle charger for phones, not for high-draw appliances
