Conventional cigarette lighter GPS devices stop updating their location when the battery runs out, AirTags require battery replacement, and GPS trackers incur monthly fees. Our company has developed a patented built-in rechargeable battery model that offers: ① Up to 3 months of operation on a full charge with the built-in battery. ② Usable when going out, like an AirTag. ③ Simply plug in to charge. ④ Compact and discreet design. Location can be confirmed using the Apple "Find My" app. Compatible with bags and suitcases. *Location information functionality is 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 the startup sound is heard. ③ Turn on Bluetooth and pair with your smartphone. *Please refer to the product page for a usage video. 【Versatile Use in One Device】① Ideal for corporate vehicle management. Reduces initial costs and eliminates monthly fees compared to GPS installation. Up to 26 devices can be registered with 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 going out, allowing for easy location confirmation. Trackable via 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】 Location tracking uses two methods: "Active Positioning" and "Passive Positioning." Active Positioning is manually updated in the "Find My" app, while Passive Positioning uses the same mechanism 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 may solve the problem; see the video for instructions. ♥ To save on shipping costs, we will ship without the original box.
