CTEK 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.

Simply connect it to the app over BLUETOOTH® or Wi-Fi and you can: • Access additional NJORD® GO features and functions • Start, stop and pause charging remotely, and enable or disable auto start • Schedule charging for any time of day • Increase or lower the output current during heavy domestic power usage • Record and display your entire charging history Open up additional features on your CS ONE smart charger • Connects automatically over BLUETOOTH® • Revive deeply discharged batteries using the ‘RECOND’ reconditioning mode • Select ‘LITHIUM WAKE UP’ for lithium-ion batteries with Under Voltage Protection (UVP) • Turn your CS ONE into a 12V power supply using ‘SUPPLY’ mode to support the battery during service work • Displays charger voltage and amperage All you need in a single app The CTEK APP also gives you access to a range of additional functions, including: • Quick connection to the CTEK customer support team • Comprehensive product FAQs and troubleshooting • Easy access to terms and conditions The CTEK APP is compatible with most CTEK connected products.

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. ## Key features - Remote charging control - Charging scheduling - Battery reconditioning modes - 12V power supply mode - Charging history tracking - Product status monitoring ## Recent user reviews (10 of 41) All indexed reviews: https://appshunter.io/ios/app/ctek-app/id1497500515/reviews.md ### 2/5 — Needs work *2026-04-27* I plugged it to my Porsche lithium battery for maintenance. The battery was ok. It started saying the the voltage was at 13.5 and needed 8 hours for a full charge. One light fully lit and one light blinking. After 5 hours the state was the same, 8 hours to fully charge. The voltage was at 13.8. Then suddenly, in 30m it went to fully charged. So it took 5.5 hours, but how can I trust these numbers if it tells me that it still needs 8 hrs of charging, and 30m later it’s fully charged? Also, it’s supposed to identify my type o battery but it doesn’t show this anywhere. How do I know that it recognized my battery? ### 5/5 — Good *2026-02-03, version 4.3.4* Good product, good app. Lack of polish language is a little minus. ### 3/5 — История зарядки *2026-01-03, version 4.3.3* А где обещанная история зарядки для CS one gen1 ? Заряд на паузу тоже не поставить ? ### 1/5 — Charger display does not reflect app *2025-11-28, version 4.1.0* Charger unit continues to flash start whilst app shows 3 bars and 4 hours to charge complete. Garbage. ### 2/5 — Cs one *2025-06-11, version 4.1.0* Предыдущее программа работала хорошо а новое лагает Исправте пожалуйста. Спасибо! ### 1/5 — Cs One koppeln *2025-03-30, version 4.0.6* CS ONE làsst sich nicht mit dem Handy koppeln. ### 1/5 — Seit neuer Software keine Koppelung *2025-03-30, version 4.0.6* Seit neuer SW lässt sich das CTEK CS ONE nicht mehr mit dem iPhone koppeln. Somit steht der volle Funktionsumfang nicht mehr zur Verfügung, da alle Einstellungen ausschließlich über die App vorgenommen werden können. Lediglich „normales Laden“ ist aktuell möglich. Ich hoffe, dass die Entwickler den Fehler möglichst schnell beheben. Vielen Dank! ### 1/5 — App is useless now *2025-03-29, version 4.0.6* This app used to work well but now it’s totally useless. I launched it and the charger just showed as disconnected. I could not get it to connect despite connecting manually in Bluetooth. Ended up deleting the app and reinstalling. Then I could not login, just kept timing out. Eventually logged in, eventually paired to the charger then stuck giving it a name! I named it and it just hung trying to apply. Gave up in the end, over an hour wasted trying to simply find out what my charger is doing! ### 1/5 — Auf einmal keine Bluetooth Verbindung mehr. *2025-03-29, version 4.0.6* Habe das Gerät jetzt zwei Wochen in Betrieb gehabt alles problemlos funktioniert. Jetzt bekomme ich mit meinem iPhone 15 Pro Max keine Bluetooth Verbindung mehr zu dem Gerät. iPhone ist auf dem neuesten Stand genauso wie die CTEK App. Dabei hatte gestern noch alles Problemlos funktioniert. ### 1/5 — Obsługa *2025-02-12, version 4.0.5* Brak języka polskiego!!! ## Frequently asked questions about CTEK App ### What does the CTEK App do?
