Will your generator run it all at once? Tap what you plug in and see your running watts, the starting surge of the biggest motor, and what is left on your generator. No generator yet? Get the size to buy. Made for power outages, storm and hurricane prep, RV trips, camping and job sites. Works offline, even when the power and internet are down. HOW IT WORKS • Tap what you plug in: fridge, freezer, sump pump, well pump, furnace fan, window AC, space heater, microwave, CPAP, Wi-Fi, TV, RV air conditioner, saws, compressors and more • Add your own items with their running and starting watts • See running watts, starting (surge) watts and what is left • Motors that cannot start are flagged, even when running watts fit • Size to buy: the running and starting watts to look for on a portable or inverter generator before you spend • Kits for storms, camping and the job site, each with its own generator • Works the same way for a portable power station's inverter FREE • The full answer for up to 4 things at once FULL PLAN (one-time unlock) • Plan as many things as you need • The full answer and size to buy for the whole plan • Pay once. No subscription. Restore it on a new iPhone. Bought the app before it was free? It stays unlocked. Good to know Numbers are typical watts for planning. Your appliances and generator may use more or less, so read the sticker on each unit. Never run a generator indoors or in a garage: carbon monoxide is silent and can kill. This app does not replace a licensed electrician or your generator manual. No account. No ads. No tracking.
