NOCO GENIUS10, 10A Automatic Smart Charger, 6V and 12V Portable Automotive Car Battery Charger, Battery Maintainer, Float Charger, Trickle Charger and Battery Desulfator with Temperature Compensation

This is not a UK version, something that really should be made clear. Still, it was simple (if tedious) enough to fit a UK plug. No earth wire - not sure if that's an issue, but I'm not an electrician. Works just the same as the Genius 5 I already have, charges fairly fast and well, and with no fuss. It tops my fairly big battery up in a few hours. It works, and reliably. My car starts strongly every time, even after a long period of lying then given a top up charge. Enough said. Excellent charger, quicker than the Genius 5 (which still did the job, only slower) but annoying that I had to read the small print to realise I'd been mis-sold a US version.

Brilliant bit of kit. Essential for my ancient Range Rover.

Very pleased with look and finish of Product. If the assories and adaper plug were included to make a superb one stop package, willingness to pay a little extra woud appeal. Overall a Quality product.

Got this on a deal. Usually quite a bit more expensive. Have several batteries that need maintaining and this does the trick. Did a fair bit of reading up on the Noco and the CTEK optimisers. Bang for buck, multiple battery types (gel,lead,etc) and waterproof put this ahead. NB. Noco do 1A, 2A and 5A optimisers as well. Depends on your needs.

This looks and feels quality, and is doing the job- it should I suppose as it is not cheap. My only gripe is there is no UK plug so I had to use an adaptor.

I liked it very much. The only thing I need to buy extra is an EU/US plug to the UK from the local store.

… easy to use and good value…

I am an amateur of knowledge about batteries. And this device meets all my requirements.
