Keis Constant Power Controller

So glad this came with the jacket AND for free!
I'm able to change the temp on the jacket so easily to suit mid-ride

A must have addition if you buy the Keis heated trousers as the jacket controller does not control both items.

Easy to use & gives three heat settings

A must have controller if you buy the Keis trousers to go with your jacket.

Once plugged in it sits nicely on your thigh, easily controlled even with gloves on.

Thankfully this is included for free when you buy their jackets which is just as well as you wouldn't want them running flat out all the time.
Simple to install and use.
The only negative is that the instructions state it's not compatible with the gloves, suggesting the controller is connected in series to both the jacket and glove elements when you would expect it to only be series with the jacket and parallel to the gloves.
But it seems to work just fine with the gloves.

Very good item of equipment which enables you to change heat settings on the go.

Really easy to operate even with gloves on, very nice that its included free with the jacket, kudos to Keis.

Hi,love my kies heated jacket, but the controller failed and apparently it's a common problem, when working it's very good.ordered a new one,as normal it came quickly and no hassle at all.
I order almost everything from sportsbikeshop, they're the best,this is not their fault.

Quality and ease of use make this essential to connect and start using the jacket without complicated delay.

The order was delivered quickly and the controller itself has worked well so far. It appears to be well made and is easy to use. It is an absolute must for using with my heated vest.

If you're buying Keis kit you need one of these. Without it your heated whatever will be on max all the time and fry you. Happily they are packaged up with some of the range currently.

I am a great advocate of Keis, however I have found the controllers to be the weak point, the early design used to leak and get filled with water ,the new design are better ,but I have experience a couple where the wire has broken where they connect to the controller, product redesign is needed. Whilst working they are a superb piece of equipment. But having to almost replace on an annual basis they aren't cheap. Sorry for the poor yet honest review.

A definite need with a keis jacket & works well.

Great stuff. Gives you freedom to choose your comfort zone quick and easy. Typical KEIS build quality.
Highly recommended
