How long does it run on a tank?
The fuel tank holds 8 gallons of gasoline. At half load, it runs about 13 hours on a full tank. That is about 0.62 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. On propane, a standard 20 lb tank holds about 4.7 gallons of LP; propane does not go stale, which makes it the easiest fuel to stock.
74 dB(A): how loud is it?
The manufacturer rates the Pulsar G12KBN at 74 dB(A), usually measured at 23 feet (7 m) and a light load. That is loud, like a lawn mower: place it as far from the house and the neighbors as the cords allow.
Can you connect it to your house?
Its panel offers 4 × 120 V household outlets (5-20R), L14-30R 30 A 120/240 V twist-lock, 14-50R 50 A 120/240 V, 12 V DC outlet. The 14-50R 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.
Safety features and warranty
It has electric push-button start, with a recoil cord as backup. The manufacturer does not list a CO shutoff sensor: be strict about placement, 20 feet from the house with the exhaust pointed away. It is listed as CARB compliant, so it can be sold in California. The warranty runs 3 years (residential use).
Typical price $800–$1,200: good value per watt?
Relative to its running watts, the Pulsar G12KBN scores 9.5/10 on value: one of the best results in our catalogue. Generator prices on Amazon move a lot, especially before hurricane season: check the current price before you buy.
