CTEK CS ONE Battery Charger And Maintenance Device With APTO Technology (Adaptive Charging), Fully Compatible With Cars, Motorcycles, Leisure Vehicles, Vans And Boats

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 does what's supposed to do and comes in a neat package and appears to be very robust. The app adds functionality to the device but be aware that it only operates by bluetooth. One of the reasons I bought this was due to the availability of the app (which I assumed would work over WiFi). My garage is separate to the house and I thought it was would be useful to check on the charging status without having to go to the garage. That isn't the case. Nonetheless it charges the battery as specified.

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.

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

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!

I wanted this to be the best battery charger ever, so ignored all the other reviews saying it doesn't work with Android, but they were right.The app connected with the charger on iOS but that was pointless. There is no clear instruction as to how any of it works.Now I've got to restart my research and identify a battery charger that honestly does the job.

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 .
