Wingman Power Miser SWS

How long will your battery really last? Power Miser answers that in one glance, for any power station or auxiliary battery bank. Tell it what you carry: your station or battery, your solar panel, your alternator charger, and the gear you run: fridge, CPAP, cooktop, kettle, lights, Starlink. Power Miser works out how many days you have on a Low, Medium and High day, what an overnight costs you, and whether everything can run at once. On the trail, check in with the percent on the unit's display whenever you walk past. Two check-ins and Power Miser knows your real burn rate, projects the next 48 hours against your reserve, and tells you the cheapest fix in plain words: drive 40 minutes, catch 3 hours of sun, or skip one appliance. Pull a real solar forecast for your position with one tap. Own a DELTA 2 or DELTA 2 Max? Power Miser reads its live charge and watts two ways, whichever suits you: sign in once with your EcoFlow account (a one-time step that needs a connection) and every reading after that comes straight over Bluetooth with no signal required; or paste your free EcoFlow developer keys for the cloud version, which works with a wider range of EcoFlow stations. Either way it shows which of your devices is drawing the most right now, right down to the socket. Print a card in the size you like, 3x5 to A4, and keep it with the unit. Works entirely offline for its core estimates. Everything stays on your phone; no Power Miser account, no ads, no analytics. The optional EcoFlow connection is the only place the app talks to anything else, and only with your say-so. All estimates are informational only and depend on temperature, battery age and cable losses. Verify your own reserve and never rely on an estimate alone for medical equipment such as CPAP machines.
