Thank you for viewing! Unlike typical cigarette lighter GPS devices that stop updating when the battery dies, AirTags that require battery replacement, and GPS trackers that incur monthly fees, we have developed a patented built-in rechargeable battery model. This model offers: ① Up to 3 months of operation on a full charge with the built-in battery. ② Usability like an AirTag when you're out and about. ③ Charging simply by plugging it in. ④ A small, discreet design. Location can be confirmed using the Apple "Find My" app. Compatible with bags and suitcases. *Location services are not supported on Android. 【Important Notes for First-Time Use】① Turn on the car's power and insert the device into the cigarette lighter for initial power-up and activation. ② Press the reset button once; activation is complete when you hear the startup sound. ③ Turn on Bluetooth and pair with your smartphone. *Please watch the usage video on the product page. 【Versatile Use in One Device】① Ideal for corporate vehicle management. Reduces initial costs and eliminates monthly fees compared to installing GPS. Up to 26 devices can be registered on one iPhone; one product is dedicated to one Apple ID. Reset is required when using a different ID. ② Equipped with USB-C & USB-A for simultaneous charging of two smartphones/tablets (up to 20W). ③ Updates location even when the engine is off with the built-in battery, useful for vehicle theft prevention. ④ Can be carried in a bag like an AirTag when you're out and about. Easily check the location. Trackable with a network of over 2 billion smartphones worldwide (no communication fees or 4G required). *Location updates are not possible if there are no Apple devices nearby (e.g., outdoors, at sea). 【How to Improve Vehicle Location Accuracy】 This product uses two types of location tracking: "Active Positioning" and "Passive Positioning." Active Positioning is manually updated in the "Find My" app, while Passive Positioning works the same way as AirTag, automatically updating via Bluetooth if there are Apple devices nearby. Location updates will not occur if there are no Apple devices. To confirm the accurate vehicle location, we recommend manual updates before leaving the vehicle. 【Q&A for When It Doesn't Work】 ① Pairing is not possible during Apple "Find My" system updates (usually 1-2 days), and location information may temporarily be inaccurate. This is not a malfunction and will automatically return to normal after the update is complete without any action required. (This is the same for the "Find My" feature built into the iPhone) ② An iPhone logged into an Apple ID is required. ③ If you cannot connect, initialization can solve the problem; see the video for instructions.
