NelumBox – Safely cool medications during travel at the touch of a button

The NelumBox is a fully automatic, electric cooler with a carrying handle, specially designed for carrying medications that require cooling.

The locking function keeps your medicines safe in the NelumBox. Thanks to RFID technology, the locking mechanism can only be opened by authorized persons. This protects your medicines from children and unauthorized access.


Day 1-10: 20€/day; From day 11: 5€/day


The Li-Ion batteries allow cooling in the desired temperature range of 2° – 8°C.  The sensor technology of the NelumBox permanently measures the temperature inside and automatically ensures that your medication neither gets too warm nor freezes. You may check this on the display.

Thanks to the long runtime of ca. 12 hours (in battery mode, rechargeable at any power socket) you do not have to worry about your medication e.g. during your flight. Recharge the batteries while operating to get unlimited runtime.

Further temperature profiles and access control without RFID card only on request.

On request, the NelumBox can also be configured for other temperature ranges (e.g. 15-25°C). In such a case, please contact us at in good time.

On request, you can receive the NelumBox without access control via RFID technology. In such a case, please contact us in good time at

Before traveling, talk to your doctor about the amount and type of medication to be taken. Your doctor will also provide you with a medication plan for the trip upon request. Be aware of possible time changes in other countries. Also, if possible, take a little more than the required amount of the medication with you so that you have a reserve for unforeseen events.

Medication may also be carried in hand luggage in larger quantities than the usual 100ml for liquids. Also syringes (which are considered dangerous objects), as well as narcotics or strong painkillers, you may take in your hand luggage. In any case, however, there must be a medical necessity. In order to avoid possible misunderstandings with the security personnel in advance, we recommend that you consult your doctor. He or she can issue a medical certificate for the trip.

The NelumBox is specially designed for use in hand luggage. You only need to make sure that the batteries of the NelumBox are charged. To do so, simply connect the NelumBox to your home power supply via the included power adapter.

Hint: Simply use the Tec4App to check the temperature. Using the Tec4App (available on Android and iOS), the measured data of the NelumBox can be viewed and tracked at any time.

On mains power indefinitely. The NelumBox maintains a temperature of 2° – 8 °C for approx. 12 hours in battery mode. If you add another battery pack, you can extend the runtime by another 12 hours even without a power source.

Note, however, that this is for a closed NelumBox. Therefore, never open the door more often than necessary to guarantee the longest possible runtime.

Tip: On longer trips, always try to charge the NelumBox from the mains when you have the opportunity to do so, this way you can guarantee an unlimited runtime.

Auf der Vorderseite der NelumBox befindet sich ein kleines Display, hier können Sie zu jeder Zeit die aktuelle Temperatur ablesen.

Sie erhalten mit der NelumBox außerdem einen Zugang zur Cloud. Die gemessenen Temperaturdaten können Sie über die Tec4App (für Android / iOS) oder im Browser einsehen.

In this case, contact the manufacturer of the drugs and ask for stability data of the respective drug. You can also download the temperature report from the Tec4App and send it to the manufacturer for verification if necessary.

You can rent the NelumBox for as long as you like. The shortest rental period is 10 days.
