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
Hardware-level battery management built for serious Mac users.
ThunderVolt follows you across your entire Apple ecosystem. Monitor charge health on your iPhone, glance at your wrist, and control everything from anywhere — no Mac required.
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 →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.
