Eufy S330 & Eufy S300 share many similarities, but there are also important differences, such as quality, performance, features, design, and connectivity. If you want the best one between them, I Would recommend the Eufy S330 rather than the Eufy S300

Why Do I Recommend The Eufy S330

  • The Eufy S330 has an integrated solar panel for continuous “Forever Power” in sunny conditions, while the Eufy S300 uses only a rechargeable battery that requires manual charging every few months.
  • Eufy S330 features an IP67 weather-resistance design for better protection against dust and temporary water immersion, whereas the Eufy S300 has an IP65 rating that only guards against rain and water jets.
  • It comes with a longer battery endurance of up to one year per charge when supported by solar energy for reduced maintenance, while the Eufy S300 lasts around six months per charge with no solar assistance.
  • The Eufy S330 has a slightly larger and sturdier build for enhanced durability in harsher outdoor environments, while the Eufy S300 uses a slimmer and lighter design.
