$2.99 · In‑App Purchases · Designed for iPad
Whether you’re off-grid van life or camping or setting up solar at home, know exactly how long your devices will last. RunTime+ calculates true runtime, & power needs!
RunTime+ is the ultimate tool to calculate your power needs and take the guesswork out of energy planning. Designed for van life, camping, RVs, portable setups, and home backup systems, RunTime+ makes it easy to understand exactly how long your devices will run on your batteries. Whether you are hitting the open road, packing up for an outdoor adventure, setting up solar panels, or preparing your home for a power outage, RunTime+ gives you confidence, clarity, and control.
RunTime+ comes loaded with brand data and ready-made selections for the gear you already own. From popular portable batteries and power stations for camping, to the inverters and solar panels trusted by van lifers, to high-capacity home batteries and backup systems, you’ll find real products built into the app. Simply pick from the list — whether it’s a Jackery, Bluetti, EcoFlow, Goal Zero, Tesla Powerwall, or many others — and RunTime+ automatically applies the correct watt-hours and inverter limits. This means no complicated math, no searching specs, and no second-guessing. Just select your gear, see the numbers, and know exactly how long your system can run.
Energy planning is usually a hassle — but not with RunTime+. Simply enter your devices, their wattage, and how often you use them. Add in your batteries and optional solar panels, and we do the math for you. The app instantly calculates your runtime, shows you where your limits are, and helps you plan smarter so you can enjoy your journey without worrying about losing power.
