Frequently Asked Questions
Yes! Chargie works with any smartphone, tablet, or device that charges via USB. The Chargie A works with USB-A chargers, and the Chargie C works with USB-C. Both support Android and iOS.
By limiting charging to 80%, you can extend battery lifespan from the typical 1–2 years to 4–5 years. Chargie’s hysteresis charging mimics how electric vehicles protect their batteries, avoiding the constant micro-charging that degrades cells.
Chargie A and Chargie C are designed for safe overnight charging at lower power to minimize heat stress. For laptops, Chargie for Laptops supports USB-C Power Delivery up to 100W, so it handles normal laptop charging speeds.
Not necessarily. Chargie has a Hardware Limiter mode that works without the app — it measures power and cuts off charging at a set threshold automatically. The app adds scheduling, precise percentage control, and monitoring.
Built-in limiters only work at 80% and can’t be customized. Chargie lets you set any limit you want, schedule top-ups, and works across all your devices — phones, tablets, laptops, and more. It also provides hardware-level cutoff, not just software.
