Six systems that work out what your battery needs — then hold it there in hardware. No terminal, no config files.
Reads three signals at once (thermal sensors, your calendar, the time of day) and adjusts your charge ceiling as they change. Hot desk? Drops to 65%. Midnight? Holds at 80%. Flight at 7am? Charges to 100% ahead of departure, timed so it finishes before you leave.
Adaptive Mode is the reason ThunderVolt exists. Set it once and it handles the rest.
Heat is the #1 enemy of lithium-ion batteries. Charging above 35°C permanently degrades capacity, and MacBooks routinely hit 45°C under load. Thermal Guard monitors CPU proximity, battery stack, and ambient sensors in real time, pausing charging when temperatures cross safe thresholds.
macOS's built-in "Optimized Battery Charging" only considers time of day. Thermal Guard reacts to actual thermals. Compiling code? Rendering video? Gaming? Charging pauses until your Mac cools down.
Your Mac's Battery Management System (BMS) drifts over time, reporting 95% health when the real figure is 88%. ThunderVolt's BMS Calibration performs a controlled full discharge/recharge cycle while monitoring 6 internal signals to recalibrate the BMS to ground truth.
The result: accurate health readings, predictable runtime estimates, and early warning when your battery genuinely needs service. Most users see a 3-7% correction after their first calibration.
See exactly how many watts are flowing into (or out of) your Mac in real time. Monitor AC adapter wattage, battery charge rate, and total system power consumption, updating every second in the menu bar.
Is your charger actually delivering 140W? Is your Mac throttling because of heat? Is something draining battery faster than it should? Live Power Flow answers these questions at a glance.
Spots calendar events with flight numbers, airport routes, and travel keywords, then pre-charges your Mac to 100% before you leave — timed backwards from departure so it finishes in time. Once you’ve left, it returns to your normal charge limit.
No more forgetting to top up before a flight. No more arriving with 65% battery because you left your limit on. Travel Intelligence reads your calendar so you don’t have to think about it. Your Mac needs to be awake and plugged in during the charge window.
Control your Mac's charging from your iPhone or Apple Watch. Get push notifications when Adaptive Mode shifts gears. Toggle modes, adjust limits, and check health without walking to your Mac.
All communication is end-to-end encrypted. Your battery data stays on your devices. The companion apps are native SwiftUI on iOS and watchOS, not web wrappers.
