14,500 W running, 18,000 W surge — sustains the well pump or a small central AC tier and everything below it.
Best forLarger homes that want whole-house portable power through a 50-amp transfer switch and will fuel it manually or from a big propane tank.
Westinghouse's biggest gas-and-propane portable, for the house where a 9,500 to 12,000 watt unit will not start the central air. It makes 14,500 running watts on gasoline and 13,000 on propane, with 18,000 peak, from a 713cc V-twin. The 14-50R outlet means a 50-amp transfer switch or a 6-50 cord feeds the panel, and copper windings with THD at or below 5% are kinder to electronics than the 23% units. It is also a very big machine: 352 lbs, 74 dBA, no recoil backup, and a 20 lb propane cylinder runs it only about four hours at half load, so a dual-fuel plan needs a larger propane tank. At $3,499 it costs about what a mid-size standby unit does before the transfer switch and install, so the choice comes down to whether you will drag it out and refuel it during a storm.
