Runtime and fuel
The fuel tank holds 6.2 gallons of gasoline. At half load, it runs about 9 hr 50 min on a full tank. That is about 0.63 gallon per hour at half load, or 15 gallons for a full day of running, so plan your fuel storage for a multi-day outage.
64 dB(A): how loud is it?
The manufacturer rates the Honda EM6500SX (EM6500SXK2AN) at 64 dB(A), usually measured at 23 feet (7 m) and a light load. That is a typical open-frame level, comparable to a vacuum cleaner: fine for home backup at 20 feet, loud for a campground.
Outlets and home connection
Its panel offers 4 × 120 V household outlets (5-20R), L5-30R 30 A 120 V twist-lock, L14-30R 30 A 120/240 V twist-lock, 12 V DC outlet. The L14-30R outlet supplies 120/240 V, which is what a manual transfer switch or an interlock kit with a power inlet box connects to, installed by a licensed electrician. Never backfeed the house through a wall outlet.
Start type, CO shutoff and warranty
It starts with a remote key fob or the electric push-button, with a recoil cord as backup. A CO shutoff sensor stops the engine if carbon monoxide builds up around it; it does not replace distance (20 feet from the house) and CO alarms indoors. It is listed as EPA compliant; check California availability if you live there. The warranty runs 3 years (residential use).
Typical price over $2,500: good value per watt?
Relative to its running watts, the Honda EM6500SX (EM6500SXK2AN) scores 4.3/10 on value: a high price per watt, which its other strengths may justify. Generator prices on Amazon move a lot, especially before hurricane season: check the current price before you buy.
