The battery decides this before the radio does

Invoxia’s site publishes 1.11 Wh, and GEGO’s FAQ publishes 2.59 Wh and describes that figure as below the regulatory threshold. LandAirSea publishes a capacity for the 54 but not the chemistry or voltage. Neither LandAirSea nor Tracki addresses airline rules anywhere in the material retrieved for this guide.

So among the cellular trackers, only Invoxia and GEGO give you a Wh figure to check. The buyer’s job is to compare the Wh figure the manufacturer actually prints against the airline’s own stated limit, not to take “luggage” in a listing title as the answer.

How a crowdsourced tag gets a fix

No manufacturer here publishes how often a tag inside a baggage sorting area or an aircraft hold gets relayed. The honest description is that the mechanism requires a participating phone within Bluetooth range, and a bag on a tarmac or in a cargo hold is somewhere few phones go. The last-known location can go stale until the bag reaches a carousel, a terminal, or a courier van. If what you want to know is which airport the bag is in, that is usually enough. If you want to watch it move, it is not.

Match the tag to the phone in your pocket

The AirTag and Galaxy SmartTag2 publish a platform requirement; the Moto Tag 2’s retrieved material lists only Google’s Find Hub network and a Google account. The requirement runs both ways: it decides which app finds the tag and which strangers’ phones can relay it.

  • AirTag (2nd generation): requires an iPhone on iOS 26.0 or later, or an iPad on iPadOS 26.0 or later, and an Apple Account. Precision Finding with the second-generation Ultra Wideband chip needs an iPhone 15 or later (excluding the 16e and 17e) or iPhone Air. No first-party Android support.
  • Galaxy SmartTag2: Galaxy devices and a Samsung Account only, with the OS-floor inconsistency noted in its pick above.
  • Moto Tag 2: uses Google’s Find Hub network and a Google account. Its Bluetooth 6.0 Channel Sounding and UWB give finer short-range finding on supported phones; the evidence retrieved does not list which phones support that.

An iPhone owner choosing between an AirTag and a Tile Pro is choosing between a network Apple’s retail listing copy puts at over a billion devices and one Life360 puts at roughly 2 million Tiles, and Tile’s cross-platform reach only pays off if the household mixes iPhone and Android and wants one tag either phone can find. An Android owner’s equivalent choice is the Moto Tag 2 on Find Hub.

When a cellular tracker earns its subscription

A cellular tracker reports position over its own SIM, so it does not wait for a stranger’s phone.

The update rates are where these differ from a crowdsourced ping. LandAirSea’s intervals run from 3 minutes down to 3 seconds, selected by subscription tier. Tracki and Invoxia both publish 30 seconds at their fastest, with Tracki naming slower Eco, Standard, and Intensive modes. No update interval for the GEGO appears in the material retrieved for this guide. If what you want is to watch a bag move between a connection’s two terminals, or to hand an airline agent a current position rather than a last-seen one, this is what the subscription buys.

The commitment is binary. All four need an active plan for cellular reporting, per each maker’s site.

The trade-off that catches people out: a tracker that needs charging

A CR2032 tag is packed and forgotten. A cellular tracker is a device you charge before every trip and that stops reporting when the charge runs out. The published runtimes vary widely. Invoxia’s and Tracki’s FAQs each quote up to 1 month under optimal conditions. GEGO’s FAQ gives 7 to 10 days of typical use, or up to 20 days if the device stays stationary, worth measuring against a two-week trip with no charger access for the bag.

None of the four has a user-replaceable battery.

When the coin-cell tag is genuinely enough

If your phone is an iPhone or an Android device and your bag is flying between airports where those phones are common, a coin-cell tag on the matching billion-device network answers the question you most want answered when a bag does not appear: which airport it is in. It needs no subscription and no charging. The AirTag’s NFC Lost Mode also lets a finder without an Apple device tap the tag and see your contact information.

It is not enough in three cases the evidence supports. If you need position updates every few seconds or every 30 seconds while the bag is moving, only a cellular tracker publishes that. If your phone is a Galaxy and you want the SmartTag2, you are relying on a network whose size Samsung does not publish. And if you want a Tile for cross-platform reasons, you are accepting a network Life360 puts at roughly 2 million Tiles.

If you go cellular for a checked bag, the choice is between the Invoxia GPS Tracker Pro and the GEGO PRO, for the reasons in the short answer above. Between them, Invoxia is 0.95 oz against 3.28 oz, while GEGO is the only one built for luggage specifically. Invoxia’s US site also lists the Pro Max, with a 2,000 mAh battery, as its new flagship and shows the Tracker Pro as out of stock; this guide did not evaluate the Pro Max.
