CTEK CS ONE, Battery Charger 12V, Smart Battery Charger, Motorcycle And Car Charger, Battery Maintainer With Adaptive Charging, App, Reconditioning, Wake Up And Supply Mode And Polarity Free Clamps

Well worth the money. Looked at all the options. This one just works. The Bluetooth feature is very useful. Robust in construction and gets on with the job with minimal issues.

The Bluetooth connection was a little confusing but once connected with the App, all was clear.The charger is great. Completely automatic.

This is a good charger, much faster than my previous one and with some extra features.The thing that really lets it down is the lack of information about how to use it, especially the app related features. I tried the Recond function on my old battery and it was very unclear what was happening. After 8 hours with no previous sign of progress I decieded to give it up as a bad job but the app was now showing Fully Charged and the battery was.For the basic charging use it is just a case of connecting it up and it works well. It is several times the price of my old charger which worked well but was slow so depends on your requirements

Very Disappointed – Completely Dead on First Use!I had a terrible experience with the CS One CTEK product. As soon as I plugged it into the power outlet, it didn’t respond at all — completely dead right out of the box. I tried different outlets and checked everything, but nothing worked. For a product from a brand like CTEK, I expected at least some basic functionality. This was a huge disappointment and a waste of money. I do not recommend this product based on my experience.Very Disappointed – Completely Dead on First Use!I had a terrible experience with the CS One CTEK product.

To make things worse, when I contacted their customer service for help or a replacement, they completely ignored me. No support, no response — nothing. For a brand like CTEK, this level of quality and service is unacceptable. I do not recommend this product at all based on my experience. Very Bad Quality – Completely DeadAs soon as I plugged it in, it never worked. The device was completely dead right out of the box. Very poor quality and a total waste of money.

Bought the CS ONE to replace an old CTEK conditioner. I needed the cigarette lighter adaptor to connect to the fitting for my car's input, and was delighted to find the Amazon bundle which suited, or so I thought.It would appear that CTEK have changed the connections on their latest products, and the cigarette lighter adaptor that Amazon bundled with the new charger is old generation, so needed an extra adaptor to connect it all together.For this bundle to work, you have to purchase the CS Connect cable, pushing the already rather high price, even higher. Very annoying!

Not used yet.Has been purchased for future useBut got in early to keep on standbySeems ok and connects to Bluetooth, yet to connect to vehicle

I have just replaced my trickle charger which gave me good service for many years with a CTEK CS ONE this is something else and so easy to use the hardest thing about it was plugging it in to the mains . It doesn’t matter which battery terminal you put the crocodile clip on or whether it’s an acid or lithium battery it sorts itself out, you can leave it on to keep your battery trickled charged. Then you can purchase a short lead which you leave permanently connected to you battery terminals then just plug your CS ONE onto it and away you go . Good piece off kit .

I fell for the AutoExpress review hype. I wanted to use this charger to restore a large, 160Ah, lead acid battery that is too discharged for my ancient charger to recover.I have yet to manage to use this charger as I only have Android smartphones at home and the CTek App has issues with Android.To quote CTek Customer Support:"I'm sorry to tell you that we have some issues with the app not functioning with android users, this will be resolved in the next update but I don't have a release date for it yet."Various functions such as RECOND, SUPPLY and WAKE UP are only accessible using the smartphone App, unfortunately none of the Android smartphones in my house, even those running the minimum supported version 10 can detect the charger allowing me to use these functions. I know that the charger Bluetooth is working as I can detect and connect to it using a Bluetooth sniffer App.To cap it all, it looks as if the MXS 7.0 has the same functionality, but without the need to use Bluetooth to turn them on and costs nigh on £100 less.
