Apple limits at 80%. AlDente adjusts software. ThunderVolt writes to your Mac's SMC chip directly — the hardware that actually controls charging.
No credit card required · Apple Notarized
AlDente and every other battery manager send instructions to macOS, which relays them to the SMC chip. ThunderVolt writes to the SMC directly — bypassing the software layer entirely. That's why we can build features they architecturally cannot.
Start Free Trial →macOS 26.4 added a basic charge limiter. ThunderVolt adds the intelligence layer on top — the features that require cross-device context, AI, and hardware depth Apple won't expose in Settings.
Apple's limiter is Mac-only. ThunderVolt lets you monitor and adjust your MacBook's charging from any device in your ecosystem, even from your wrist.
Apple stops at 80%. ThunderVolt lets you set 50% Storage Mode, 60%, 70%, or any custom threshold below what the native UI allows.
Tracks your real health trend as −%/month and predicts your battery replacement date before Apple Health even moves a point.
Monitor every Mac in your household or workspace from a single iPhone view. Private CloudKit sync — your data never leaves Apple's infrastructure.
ThunderVolt reads your calendar. Detected a flight tomorrow? It automatically charges to 100% and drops back to your limit after landing.
Pauses charging at the SMC level when your Mac overheats — not a software pause, but a real hardware inhibit that no other app can do.
Apple's native charge limiter is Mac-only. ThunderVolt lets you monitor and adjust every MacBook in your household from your iPhone or Apple Watch. Toggle Storage Mode, view live charge, get heat alerts — from any room, any device.
Start 7-Day Free Trial →ThunderVolt tracks your real health trend as −%/month and predicts your battery replacement date months before Apple's Battery Health indicator moves a single point. No guesswork. Just data.
See All Pro Features →Your limit is 75%. You have a 3-hour flight tomorrow at 9am. ThunderVolt sees it in your calendar, charges to 100% tonight, then drops back after you land. No other app in the world does this.
