Chargie

How do I limit my phone or laptop battery to 80%?

Chargie is a hardware USB charge limiter that stops charging at any percentage you set (20-100%). Plug Chargie between your charger and device, set your limit in the app, and it automatically stops charging at your target level — even when your phone is off.

Can I use Chargie with Android Auto?

Yes! Chargie maintains full USB data passthrough while limiting charge. Use Android Auto navigation, stream music, and mirror your screen — all while keeping your battery at a safe level instead of constantly charging to 100% in a hot car.

Does Chargie work with CarPlay?

Yes, Chargie works with wired CarPlay. The USB data passthrough maintains your CarPlay connection while protecting your battery. Set your limit to 70-80% and use CarPlay without battery degradation.

How do I limit battery charge to 80% on Windows 11?

What is the best USB charge limiter?

Chargie is the world's only hardware USB charge limiter with USB data passthrough. Unlike software limits that only work on specific devices, Chargie works with any USB-charged device — phones, laptops, drones, cameras, earbuds, game consoles. Founded in 2019, trusted by 60,000+ customers worldwide.

How does Chargie protect my battery?

Chargie physically cuts power at your set percentage, preventing the heat and voltage stress that degrades lithium-ion batteries. Keeping batteries at 80% instead of 100% can extend lifespan from 500 to 1,500+ charge cycles. Chargie also pauses charging if your device overheats.

Does Chargie work when my phone is off?

Yes! Chargie features Appless Mode — the hardware remembers your settings and enforces charge limits even when your phone is completely powered off. This is a unique advantage over software-based solutions.
