Hong Kong Generator Buying Guide and Tips

• Right size, right load: Add up essentials (fridge, lights, router, pumps). Flats often only need 1.6–2.2 kW inverters; worksites/houses may need 5–20 kW+ diesel.
• Noise & space: Inverter units ~50–60 dB; open-frame petrol/diesel can exceed 75 dB. Check building management noise rules.
• Fuel choice: Petrol inverters are portable and quiet. Diesel is efficient for long use and construction. Dual-fuel options simplify storage.
• Electrical safety: Use a licensed electrician for installation. Always use an ATS or manual transfer switch—never back-feed CLP/HKE supplies.
• Power quality: Keep electronics safe with pure-sine inverter units or AVR-equipped gens.
• Cords & outlets: Use 230 V, Type G rated cords (10–12 AWG equiv.). Protect from moisture and use RCD protection.
• Maintenance: First oil change early, then per manual. Keep spare oil, filters, and plugs. Test-run monthly with a load.
• Weather & storage: Hong Kong humidity requires dry, ventilated storage. Use running covers and rust-resistant enclosures.
• Accessories: Stock fuel cans, funnels, wheel kits, rated generator cords, and UPS for routers.
