It sits between the charger and charging cable and gives the companion app a physical way to switch charging power off and on. For percentage-based control, the Chargie app reads the device's battery level and tells the hardware to switch power off at the chosen limit. The user can also choose an Allowed Charge Drop: the distance below the limit at which charging may restart. This control requires the app to remain running and connected over Bluetooth with the background permissions described in the relevant platform guide. Chargie has free companion apps for Android, iPhone and iPad, Windows, macOS, and Linux. There is no subscription for charge control. Features vary by Chargie model, firmware, charger, device, and operating system. Chargie is made by **Lighty Electronics SRL** (RO35245011), based in Timișoara, Romania. Chargie was created by Ovidiu Sandru and has been developed since 2019. The [About Chargie](https://chargie.org/about-us/) page contains the company and creator story. ### Why manage charging? Long periods at a high state of charge and elevated temperature contribute to lithium-ion battery aging. Using a lower everyday limit can reduce time spent fully charged and may help slow future wear. The result is not a fixed lifespan multiplier: it varies with battery chemistry, age, temperature, charging setup, and use. Chargie supports battery health and battery protection habits intended to help extend battery life, without promising a particular outcome. Chargie is a preventive charging tool. It cannot restore capacity already lost through chemical degradation. If a device's built-in charge controls already fit the user's routine, those controls may be enough. --- ## How Chargie Works 1. Choose the Chargie model that matches the charger's connector and power requirements. 2. Place Chargie between the charger and the usual charging cable. 3. Connect the free companion app over Bluetooth and choose the desired controls. 4. While connected-app percentage control is active, the app reads the battery state and tells Chargie when to switch charging power off or on. Chargie controls the availability of charging power. The attached device still determines how much current it draws. Chargie does not contain a battery and does not require root access or an iOS jailbreak for its normal app-to-hardware control. ### Charge limit and restart range The connected app lets the user select a charge limit, such as 80%. When the device reports that level, Chargie switches charging power off. The user also chooses the Allowed Charge Drop. For example, an 80% limit with a 5% drop keeps power off until the reported level reaches 75%, avoiding rapid switching around the limit. Precise percentage control depends on a live app connection. It should not be described as an exact percentage limit while the phone or laptop is off or the app is disconnected. ### Weekly scheduling and morning top-ups The scheduler supports different target levels and times for individual days. A user can hold a lower base level overnight and ask the app to begin a higher top-up for the morning. The app estimates when to start from recent charging behavior. Actual start time and charging time depend on the device, charger, app connection, and the data the app has learned. The homepage describes scheduling around daily routines. Charging times are set by the user; no electricity-price optimization claim is made here. ### Android temperature control The Android app can read the phone's reported battery temperature while connected. The user can set a threshold above which the app tells Chargie to pause charging, then resume after the phone cools. This temperature threshold is an **Android app feature**. Availability on other platforms is not claimed, and the Android app must remain connected for the feature to act on the phone's reported temperature. ### Hardware Limiter Hardware Limiter responds to power flow instead of a battery percentage reported by the device. In Basic mode, a user configures a fixed cutoff threshold. Smart mode can react to a drop in charging power on supported USB Power Delivery setups. After configuration, a supported Hardware Limiter setting is stored on Chargie and can operate if Bluetooth disconnects or the attached device is off. Because this mode responds to power, it does **not** provide the same precise percentage target as the connected app. Available modes depend on the Chargie model, firmware, charger, and attached device. ### USB data passthrough and charging pace Supported model, cable, device, and firmware combinations can preserve USB data while Chargie controls charging power. This can be useful with Android Auto, wired CarPlay, or a device connected to a computer. Compatibility should be checked for the intended setup rather than assumed for every USB device. Chargie A Gold and Chargie C Basic are designed for gentle, low-power phone charging. Chargie for Laptops supports USB-C Power Delivery up to 100W and also offers reduced-power behavior on compatible setups. Actual charging speed depends on the device, charger, cable, and selected mode. --- ## Product Catalog Prices and stock are intentionally omitted here because Chargie uses live currency and availability data.

Put the matching Chargie between the charger and cable, connect the companion app over Bluetooth, and choose an 80% limit. While the app is running with the required permissions, it reads the battery level and tells Chargie to switch power off at the target. The restart range determines when power may return. ### Does percentage control work while the attached device is off? Not as an exact percentage target. Precise percentage control requires a live app connection because the app reports the battery level. A configured Hardware Limiter mode can work without that connection on supported setups, but it responds to charging power rather than a precise battery percentage. ### Can I use Chargie with Android Auto or wired CarPlay? Supported USB data-passthrough setups can keep a data connection while Chargie controls charging power. Availability varies by Chargie model, phone, vehicle, cable, and firmware, so compatibility should be checked for the intended setup. ### Does Chargie provide temperature protection on iPhone, Windows, macOS, and Linux? The battery-temperature threshold described on the Chargie homepage is an Android app feature. While the Android app is connected, it reads the phone's reported temperature and can tell Chargie to pause. Availability on other platforms is not claimed. ### Does Chargie work without the app? The app is needed to configure Chargie. Percentage-based limits and scheduling require the connected app. On supported models, Hardware Limiter stores a power-threshold setting on Chargie and can operate later without a live app connection. ### What if the device already has a built-in charging limit? If the built-in control fits the user's routine, it may be enough. Chargie can add an external controller for a compatible device without those controls, a different charge target, or scheduled top-ups across compatible setups. ### Can Chargie restore an already worn battery? No. Lost battery capacity results from chemical degradation and cannot be restored by a charging accessory. Chargie helps manage charging habits that affect future wear; the difference over time depends on the battery, temperature, and use. ### Can I charge to 100% when needed? The user can raise the connected-app target when a full battery is needed or use an on-demand scheduled top-up. Actual charging speed and completion time depend on the setup. ### Does Chargie work with Samsung phones, iPads, and other tablets? Chargie A Gold and Chargie C Basic are intended for compatible phones and tablets, including compatible Samsung and iPad charging setups. Choose by connector, charger, cable, and power requirements rather than by device name alone, and use the [compatibility guide](https://chargie.org/which-chargie/) before ordering. ### Does Chargie support fast charging? Chargie A Gold and Chargie C Basic emphasize gentle, low-power phone charging. Chargie for Laptops supports USB-C Power Delivery up to 100W with a suitable charger and cable. The actual speed depends on the device and complete charging setup; consult the current product specifications for the chosen model. ### How do I check battery health? Use the battery-health information provided by the device or operating system where available. Menu names and reported metrics vary by manufacturer, model, and software version. Chargie manages future charging habits; it does not diagnose a battery or restore lost capacity. ### Is the companion app free? Yes. The companion app is free, and there is no subscription for charge control. ### How do shipping, taxes, and returns work? Tracked shipping is available worldwide. The shop and checkout show the applicable shipping options, thresholds, delivery information, taxes, and final total for the destination. The return window is 30 days from purchase, subject to eligibility and the published conditions. Change-of-mind and incompatibility returns generally exclude original shipping and require the buyer to cover return shipping. Read the [shipping terms](https://chargie.org/shipping-terms-and-conditions/) and [returns and refunds policy](https://chargie.org/refund_returns/) before ordering. ### How can a business request an invoice? Use the [invoice request page](https://chargie.org/get-your-invoice/). ### Does Chargie contain a battery or change charging current? Chargie does not contain a battery. It switches charging power on and off; the attached phone, tablet, or laptop controls the current it draws. Charging power and speed still depend on the Chargie model, charger, cable, attached device, and selected mode. ### Is Chargie waterproof? Chargie is not presented as waterproof. Keep it dry and follow the current setup, product, and safety guidance for the chosen model. ### Can one Chargie be used with more than one device? A Chargie can be moved between compatible charging setups and reconfigured for the attached device, but it controls one connection at a time. Recheck the model, power, cable, and app settings whenever the setup changes. ### Which payment methods are available? Use the checkout to see the payment gateways currently available for the order and location. Payment methods can change, so this reference does not keep a fixed list. ### Where can I get setup help or contact Chargie? Start with [Getting Started](https://chargie.org/welcome/) or [Support and troubleshooting](https://chargie.org/troubleshooting/). For individual help, use the [contact page](https://chargie.org/contact-us/). --- ## Comparisons with Other Approaches ### Built-in phone and laptop controls Built-in charging limits and optimized charging can be useful and may be sufficient. Their available limits and scheduling behavior depend on the manufacturer, model, and operating system. Chargie is an external hardware option for compatible setups when those controls are absent or do not fit the desired routine. ### Vendor-specific laptop utilities Utilities such as Lenovo Vantage, Dell Power Manager, and MyASUS serve supported devices from their respective manufacturers. Chargie for Laptops uses external USB-C PD hardware, but this does not make it compatible with every laptop: the laptop, power supply, cable, operating system, and required power must match the supported setup. ### Software-only charging tools Software tools may provide useful control on supported devices. Chargie adds an external switch in the charging path. Its exact percentage control still depends on the connected app; only the power-based Hardware Limiter can operate without a live app connection after setup. ### AlDente on macOS AlDente is a software charge-management option for supported Macs. If its controls fit the user's Mac and routine, it may be sufficient. Chargie for Laptops is an external USB-C PD option for compatible setups and can also be configured from macOS; its exact percentage control still requires the Chargie app connection. ### Optimized Battery Charging and adaptive charging Apple Optimized Battery Charging and similarly named adaptive or battery-protection features can delay or limit charging on supported devices. Their controls and behavior vary by manufacturer, model, and operating-system version. They may be enough when they fit the user's routine. Chargie offers a user-selected target and scheduling through an external controller on compatible setups. ### Custom ROMs and rooted Android tools Custom-ROM tools, Advanced Charging Controller (ACC), Battery Charge Limit, and similar software may manage charging on supported rooted Android phones. Support depends on the phone, ROM, kernel interface, and software version. Chargie's normal control does not require root access or an operating-system modification, though exact percentage control still relies on the connected companion app. ### Manual unplugging Manually unplugging at a chosen level is a valid charging habit. Chargie automates power switching for compatible setups so the user does not need to watch the battery level continuously. --- ## Battery-Health Background Two well-supported factors matter for lithium-ion battery aging: 1. **Time at high state of charge.** A battery held near full charge experiences more voltage-related stress than one spending less time at that level. 2. **Temperature.** Elevated temperature contributes to faster chemical aging, especially when combined with a high state of charge. Limiting the everyday target and delaying a higher top-up until it is needed can reduce time spent fully charged. Results vary, so Chargie does not promise a particular lifespan multiplier, cycle count, retention percentage, or replacement year.
