Key Features

Small and simple to use 

Touchscreen technology makes the t:slim X2 insulin pump simple to learn, teach and use. All the information you need at a glance and intuitive menus makes it simple to keep track and make adjustments when needed. Technology that fits in with your lifestyle. 

Small Size

The t:slim X2 insulin pump is up to 38% smaller than other CGM enabled pumps and can hold up to 300 units of insulin. Thanks to Micro-delivery™ technology and an innovative, flat insulin cartridge design, it takes up less space than other pumps, yet still holds a large amount of insulin.

Environmentally friendly 

The t:slim X2 insulin pump reduces environmental impact by using a rechargeable battery that can be charged from a plug socket, car, or a computer without interrupting insulin delivery. The rechargeable battery lasts up to seven days on a full charge, meaning no buying and disposing of batteries, and you can use any existing mini USB charger, or the one that comes with the pump.

Remote feature updates

The pump that gets updated, not outdated. The t:slim X2 is the only pump that allows you to remotely update features on your insulin pump using a personal computer using the Tandem Device Updater (TDU). This is a programme that you download to your computer that manages and delivers remote pump updates on the t:slim X2. 

Personalise your pump

You can personalise your t:slim X2 insulin pump to deliver a steady amount of insulin to meet your changing needs throughout the day. Six unique profiles tailor your insulin delivery, basal rates and target blood glucose.

Responsible Use

Responsible Use of Control-IQ™ Technology 

Even with advanced systems such as the t:slim X2 insulin pump with Control-IQ technology, you are still responsible for actively managing your diabetes. Control-IQ technology does not prevent all high and low blood glucose events. The system is designed to help reduce glucose variability, but it requires your accurate input of information, such as meals and periods of sleep or exercise. Control-IQ technology will not function as intended unless you use all system components, including your CGM, infusion sets and pump cartridges, as instructed. Importantly, the system cannot adjust your insulin dosing if the pump is not receiving CGM readings. Since there are situations and emergencies that the system may not be capable of identifying or addressing, always pay attention to your symptoms and treat according to your healthcare provider’s recommendations.


Responsible Use of Basal-IQ® Technology

Systems like the t:slim X2 insulin pump with Basal-IQ technology are not substitutes for active diabetes management, as there are common scenarios in which automated systems cannot prevent hypoglycemia. The Basal-IQ feature relies on continuous CGM readings and will not be able to predict glucose levels and suspend insulin delivery if your CGM is not working properly or is unable to communicate with your pump. Be sure to always use your pump, cartridges, CGM, and infusion sets as instructed and check them regularly to make sure they are working properly. Always pay attention to your symptoms, actively monitor your glucose levels, and treat according to your healthcare provider’s recommendations.

Important Safety Information


  1. If your glucose alerts and CGM readings do not match your symptoms and expectations, you should perform a fingerstick to confirm your blood glucose level.
  2. Software updates are only available to customers who are in warranty at the time they update their pump, and may require additional training.
  3. Basal-IQ Technology and Control-IQ Technology are not substitutes for active self-management of your diabetes.
