Four wired probes, one base, one phone
The IBT-4XS is a wireless thermometer of the classic design: a small base unit at the grill, probes on cables, and the readings sent over Bluetooth to your phone. Up to four probes plug into the base at the same time. Each one measures its own piece, and the display on the base shows the temperatures even when the phone is lying in the kitchen.
On Amazon it costs approx. €49.99 (as of 10.11.2026). ASIN B076QBJVWX is listed there as the variant “IBT-4XS+4 Temperatursonden”.
In our category grill thermometers it therefore sits between the pure four-probe wired devices and the wireless spikes, which cost more in our catalog. A device like this is meant for anything that stays on the grate for a long time: a roast in a kettle grill, three pieces in parallel on the gas grill, a pork shoulder in a smoker. If you only want to prod a steak briefly, an instant-read thermometer is quicker. Which design suits which job is explained in our guide Grill thermometers: insertion, wireless or fully wire-free?.
Base unit, display and probe cables
The base is made of plastic, and Amazon lists an item weight of 247 g. The four probe sockets sit side by side at the bottom, as the product photo also shows. It is operated with a single button on the front that has several jobs: switching on, pairing, stopping the alarm. Tapping twice rotates the display. On the back there is also a slide switch for ON and OFF.
Inkbird speaks of a large LED display. It shows temperature, probe number, the unit (°C or °F), the battery level and the Bluetooth status. According to the manufacturer, rotating is meant to let you read the values from any angle, for example when the base hangs sideways on a metal leg. The back is magnetic for that purpose.
The probes hang on Teflon cables with a stainless steel braid. The manual gives the length as about 150 cm, the specification on the product page as 1.5 m. That is enough to put the base next to the grill instead of on it, and because of the heat limit of the housing that is exactly the right place (more on this below).
After switching on, the device checks the sockets. For each occupied socket the probe indicator flashes briefly, in turn from 1 to 4. If an occupied socket stays dark, its plug is not seated properly.
According to Amazon, the box contains a USB cable, four probes and an instruction manual. As met standards Amazon lists EMC, ETL and WEEE (WEEE reg. no. DE 31070039), and China as the country of origin.
In detail: what a wired probe measures and where the limit lies
An insertion probe does not measure along its whole length but at the tip. That is why Inkbird requires the tip to sit in the middle of the food. With a flat piece that means inserting from the side, otherwise the sensor sits too close to the hot surface. Which core temperature to aim for with which meat is in our core temperature chart.
The measuring range has two limits. For short periods the probe measures from 0 to 300 °C, in continuous operation from 0 to 250 °C. For core temperature that is no issue, as it lies roughly between 50 and 95 °C for meat.
It looks different if you lay one of the four probes on the grate as a cooking chamber probe, to read the air temperature next to the meat. With low and slow in a smoker you stay well below 250 °C. Directly above the embers of a charcoal grill or above a gas burner at full power, however, the air at grate height can exceed this mark, and then the warning from the manual applies, which we reproduce word for word in the safety section. Our rule of thumb: measure the cooking chamber only in the indirect zone.
For accuracy Inkbird states ±1 °C (±2 °F). Whether this value holds over the whole range up to 300 °C or only in part of it is left open in the documents. A one-degree deviation is uncritical for core temperature: the difference between a steak at 54 and at 56 °C is no big deal.
The measuring range starts at 0 °C. This matters for the ice water check described in our buying guide: 0 °C is exactly the lower edge here, so the least favorable point of the scale for a calibration check.
App, Bluetooth and range
The app is called BBQ GO and is free in the App Store and on Google Play. To pair, you switch on Bluetooth and, on Android, according to the manual, also the location service (GPS). Then you open the app, start the search and hold the button on the device for about three seconds. No PIN code is needed.
On range, two manufacturer statements differ slightly. The specification on inkbird.com gives 150 ft or 46 m, while the product text in the EU shop and on Amazon say 50 m. Both go back to the same 150 feet: converted that is 45.7 m, so the 50 m is rounded up. We work with 46 m, and that outdoors. House walls, metal window frames and the grill itself dampen the signal, and indoors it will be correspondingly less.
The IBT-4XS has no Wi-Fi. In the manufacturer’s comparison table there is a cross next to WiFi. So the connection ends where Bluetooth ends, and a glance at the phone from the supermarket does not work.
In the app you set a target temperature per probe. Inkbird mentions alarms for high and low temperatures and twelve preprogrammed meat modes. Amazon adds an alarm when switching off and on connection loss, and says the presets stay saved when switching off. In the manual, an app screen also shows a timer and a field labeled “Temperature History”.
What this field shows is unclear. In the FAQ on the product page Inkbird writes that the IBT-4XS shows only the current cooking data, and nothing can be saved or downloaded. If you want to save a cooking history for later, to plan the next pulled pork better, you should expect this answer.
Is the battery enough for a long smoker day?
For most cooks yes, for sessions over 20 hours it gets tight. In the product text Inkbird gives up to 20 hours on a full charge, and the comparison table on the same page gives 25 hours. The manufacturer prohibits recharging during operation.
A lithium battery with 1000 mAh is fitted, built in and not removable. A spare battery in the drawer therefore does not help. According to the manual it is fully charged after about two hours, via the supplied 50 cm USB charging cable. You see the battery level on the display and, according to Amazon, also in the app.
In one product description Amazon gives 60 hours of runtime. This number appears at the manufacturer in only one place, and that is for the sister model IBT-4XC. Whether Amazon mixed the two up, we cannot say. We plan with the 20 hours from the manufacturer’s text, because that is the most cautious of the three figures.
In practice that means: charge fully before a long smoker day, because the device must not be plugged into the mains in the middle of cooking. For a session that stretches over a night and the following day, we would keep a second thermometer ready as a backup.
Safety and care according to the manual
The safety notes are on pages 1, 2 and 7 of the manual. Here in full and as close to the wording as the translation allows:
- The probes and cables withstand 300 °C for short periods and 250 °C continuously. If this temperature is exceeded, probes and cables burn through. Above all, cables and probes must never be placed directly in the burning flame or on the heating element.
- Do not immerse probes and cables in water for long, as this can lead to inaccurate readings.
- Do not squeeze probes and cables hard. The plastic sheathing of the cable can break and cause a short circuit.
- Remove the silicone cap at the end of the sensor before use.
- Do not place the device in hot places. The plastic magnetic back must not get warmer than 80 °C (176 °F), otherwise the device melts.
- Operate the device with at least 20 cm distance between transmitter and body (FCC notice).
The older product text in the EU shop even gives only 55 °C (131 °F) for the plastic and requires peeling the protective film off the display before first use. Between 55 and 80 °C we choose the more cautious figure. A grill lid above a cooking chamber at 200 °C can get considerably hotter than that on the outside. Better places for the magnet are a metal side table, the leg of a grill cart or the fridge within reach.
On water, Inkbird says two things. In the comparison table on the product page there is a cross for the IBT-4XS under Waterproof, so the base has no water protection. And the manual FAQ answers the question of whether probes and cables are waterproof with no: only the tips that go into the meat are. The manual has no cleaning instructions of its own, and Amazon gives only “wipe” as a care note. Our conclusion from these statements: the probe tip tolerates water, the cable and the transition to the tip do not belong under the running tap, and the base stays indoors when it rains.
The squeezing warning concerns cable routing. A heavy lid that closes on the cable presses it together every time. Where your grill has an opening or a feed-through, we would route the cable through there.
What Inkbird leaves open
A few things we did not find in any of the documents, neither on the two product pages nor in the manual:
- the dimensions of the base unit (Amazon’s 20 cm item length is probably the packaging) and whether the 247 g were weighed with or without probes,
- length, diameter and material of the probe tip,
- a separate cooking chamber probe or a grate clip in the scope of delivery; the product photo shows two metal clips, but they do not appear in Amazon’s parts list,
- the Bluetooth version of the device itself,
- the connector type of the charging socket (the drawing in the manual shows USB-A to a small plug, nothing more),
- whether the display is backlit (Amazon says yes, Inkbird does not comment),
- whether the base itself beeps on an alarm and how loudly,
- availability and price of replacement probes.
Three alternatives from our catalog
| Model | The difference | Price | Our rating | Choose this one if |
|---|---|---|---|---|
| Inkbird IBT-4XS (this one) | 4 wired probes, Bluetooth only (46 m) | approx. €49.99 | 8.8 | you cook up to four pieces in parallel and stay near the grill |
| ThermoPro TP25 | 4 wired probes, 200 m range according to ThermoPro | approx. €36.99 | 8.4 | the phone should still get readings inside the house |
| ThermoPro TempSpike Twin | 2 wireless probes (IP67) instead of wired probes | approx. €62.99 | 8.9 | you do not want to run a cable through the lid or smoker door |
| MEATER 2 Plus | 1 wireless probe with ambient measurement | approx. €118 | 9.5 | you mostly cook a single large piece |
The prices are the reference values from our price boxes and change constantly at the retailers. The rating is our editorial assessment based on the manufacturer data, and we measured nothing on any of the four devices.
When the IBT-4XS fits and when another thermometer does
The first question is the number of pieces. If you regularly cook three or four things at once, say two chicken drumsticks, a coiled sausage and a probe in the cooking chamber, you need four measuring points. Among the four devices in the table, only the IBT-4XS and the ThermoPro TP25 have that.
Between these two, distance decides. If you stay at the grill or on the terrace, the Inkbird’s 46 m is enough. If you want to read along indoors on the sofa while the smoker stands at the back of the garden, the higher manufacturer figure speaks for the TP25. The ThermoPro TP25 is also about €13 below the IBT-4XS at approx. €36.99. If you also want to check from on the road, you need Wi-Fi. For that Inkbird itself has the IBT-26S with Wi-Fi and Bluetooth, 70 m radio range according to the manufacturer’s table, ±0.5 °C, 4 to 6 probes and a 2500 mAh battery. We do not carry it in the catalog.
Cables are the second point. Every wired probe has to get out of the grill somewhere, and the manual’s squeezing warning applies every time the lid closes. If you rarely cook more than two pieces and want no cable in the gap at all, take the ThermoPro TempSpike Twin. It costs about €13 more than the IBT-4XS but has only two probes.
For a single large piece, a whole chicken or a beef roast, the MEATER 2 Plus is the more consistent solution, because it needs no cable and measures the surroundings as well. It costs approx. €118, so about €68 more than the IBT-4XS, for one probe instead of four.
And then the location. If your grill stands outdoors without a roof, and you leave the thermometer outside even in showers, the IBT-4XS is the wrong choice: the base has no water protection. According to the manufacturer’s table, Inkbird’s IBT-4XC has IPX5. You are equally wrong with it if you run sessions over 20 hours in a row and do not want to swap in between.
Our assessment: for someone who fires up a kettle or gas grill at the weekend, wants to keep several pieces in view at once and stays within earshot of the grill, the IBT-4XS is a sensible choice. Anyone who wants to stick the thermometer on the hot lid, leave it standing in the rain or read it from the office should reach for one of the other devices.
