Keep their batteries healthy with a Chargie

Frequently Asked Questions

How much does Chargie cost?

Chargie is a one-time hardware purchase with no subscription — the app is free. Price depends on the model (USB-A vs USB-C vs the 100W laptop unit) and pack size; Double/Family/Flock multi-packs lower the per-unit cost (up to 10% off for 4). See the options above for current pricing.

Which Chargie model should I buy?

Pick by your charger: Chargie A (USB-A) for older/slower chargers and most phones and tablets; Chargie C Basic (USB-C up to 20W) for newer phones with a smaller form factor; Chargie for Laptops (USB-C up to 100W) for USB-C laptops — note it needs a 100W power supply for laptop charging.

Does Chargie work with my iPhone, Android phone, or laptop?

Yes. Chargie works with iPhones, Android phones, tablets, and USB-C laptops. Match the model to your charger type (USB-A, USB-C 20W, or 100W laptop) and the free app sets your charge limit.

Is there a subscription or ongoing fee?

No. Chargie is a one-time hardware purchase and the companion app is free — no subscription, no recurring charges.

Do you offer multi-packs or discounts?

Yes. Double Pack (2) saves 5%, Family Pack (3) saves 8%, and Flock Pack (4) saves 10% per unit — ideal for households with several devices.

Do you offer free shipping?

Free shipping applies automatically at checkout on qualifying orders.

How does Chargie actually extend battery life?

It caps your charge at a level you set (e.g. 80%), keeping the battery out of the high-stress 80–100% range that accelerates lithium-ion aging. Staying in the 20–80% band measurably slows long-term capacity loss.

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.
