About this app

The CTEK APP keeps you on top of all your compatible CTEK charging products, right there in the palm of your hand.

Quickly installed and simple to use, the CTEK APP syncs your CTEK products to your smartphone via BLUETOOTH® and Wi-Fi, or by using BLUETOOTH® only.*

From the clear, easy to read home page you can check the status of all CTEK products that are within range and unlock extra product features to give you even more control. It’s designed to work effortlessly with all compatible CTEK products, including the NJORD® GO portable EV charger** and the CTEK CS ONE smart charger.

• Full charging history page (NJORD GO only)
• Date filtering in history page (NJORD GO only)
• General bug fixes

* BLUETOOTH® and Wi-Fi compatibility is subject to product type. Some connected product functions might not be available.

** We call the NJORD® GO an ‘EV charger’ but technically speaking, it’s ‘Electrical Vehicle Supply Equipment’ (EVSE) that provides a safe supply of electricity to power the on-board battery charger in your EV. Most people use the term ‘EV charger’ so to keep things simple, we’re going to use this term as well.

Ratings and reviews

I've had no issues with a CS One charger. Using Android v12 "Snow Cone" (on a Sony Xperia 5 II). I downloaded the app, created an account, switched on Bluetooth on my phone, connected the battery and switched the power socket on. On the app there is a plus button at the bottom to find/add a charger. It found it straight away and said there would be 4h until it completed. Job done and very easy. I would like to see more detailed info displayed about the battery though, if it's possible.

After firmare upgrade it stopped working or pairing saying wrong pin or passkey then had a totally different device name. Sent details to support. This is brand new out of the box. Terrible. It is Sunday. Flat battery and dead charger. Just great. Update. Unit replaced under warranty. Have yet to test the new unit or see if the firmware issue will destroy this one. They cannot expect retailers just to keep issuing new units.

I don't know if it's the charger or the app that is the problem. I have a Njord GO. Tonight, I connected it to the car to charge, and when I opened the app, there was no charger there anymore. Tried to connect it again a couple of times, but the app can't find it anymore. And the car isn't charging either. Had problems before with the schedule. Every time I tried to change it or turn it off, the app freezes. After reinstalling the app I got the schedule changed once before it freezed again. 👎
