Keis heat and power bank, expensive

[D#head]

I've used the bike power for my heated jacket for a year or so but find jumping from bike to bike is a pain, buying two or three harnesses, it's becoming expensive, decided to buy the small power bank from keis, not cheap, it only lasts three hours, they have made there own plug on there garmets so you can only us there expensive products, after a little digging on aliexpress I found a adapter to plug into there garment then to usb, it plugs into my own powerbank and it lasts three full days riding before charging,
I already had my own power bank, the adaptor only cost under £2. I don't use bike harness any more.

A linky too the item at Ali Express would be a nice gesture...

I am not sure that I understand post #1.

On each of the two or three bikes, there is one lead to supply power to the garment. Most people use something like an Optimate lead, doubling it up for use with a battery tender or as a power supply to a compressor to pump up a tyre, following a puncture.

The next is some method of regulating the heat of the garment. This I guess is the ‘harness’ you are referring to. Surely this is connected to the garment, not to each of the two or three bikes?

It would be helpful if you:

A. Told people the make / model of the power bank, which lasts three full days of garment heating use between charges.

B. Gave people a link to the adaptor lead.

PS Anyone who owns and runs two or three motorcycles, can probably afford a couple of harnesses.

I’m with Wapping. This looks like a solution looking for a problem!

Even the official Keis connecting lead is less than £20…

 

[vRSG60]

Any jack plug lead, of the right connection size, will do. Pennies on Amazon.

It's only a problem when you don't have the answers
If you are like me and don't want a lead running from the bike and want the battery to last more than a few hours,
Wrapping you seam like a clever bloke work it out what size power bank you would need to run your heated stuff and how long.

 

[Santa-2512]

It only works if your doing short journeys

On 10 hr run id flatten the battery in a couple of hrs

I run a Keis waistcoat and insoles from the same lead with a Hella/DIN socket on the end. Keis runs at relatively low current compared to other makes so even two devices do not go over the 5A limit on my R1200RS or S1000XR accessory sockets.

I also find that a Gerbing Y piece works fine to split power from the single Keis power lead to each Keis device. Yes, they are slightly different size connectors but not enough to stop a decent enough connection.

Perceptions are often misleading.

As I power my electric clothing from the bike, I have no great interest in the block per-se, but it might well interest others.

Perhaps though, instead of saying the power block will last three days of use, you’d be better off telling the forum how many hours of use, that equates to.

For example, 20 minutes use between 09:00 and 10:00 followed by 30 minutes between 15:00 and 16:00 does not equal seven hours, nor one day.

Am I wasting my time post useful info to me, is that not what forums are about or has this place lost that because of the negativity that comes with posting, saying that it's the same crap as Facebook, think I'll just leave it.
Not trying to get into anything with anyone,

 

[Wapping]

Indeed that is one purpose of forums.

The opening post wasn’t too clear on the specifics of the various items you’d bought, not least what the ‘harness’ is. That’s now sorted out.

If you can give bods the details of the power brick that lasts three days and (hopefully) the USB A to DC lead, suitable for the Keis 5.5 x 2.1 plug, everything will be hunky-dory.

@D#head ignore the haters bud - I found that info pretty useful, and I've just ordered a replacement plug based on the info you provided so I can run my compressor from my Keis power socket. It's a community here, and sometimes people's true meaning is lost as they type, meaning answers can read differently from how they are written.

I ended up buying this battery block (15000mah version at the time) for my daughters' keis jacket - it plugs directly in.

Keis Battery


It's quite a bit larger than the 15000mah hour battery packs you get from amazon that charge your phone.....so have no idea what would be better - if the capacities are the same, perhaps it is the max current delivery that separates them, otherwise going the route of D#head is probably the way to go - get an adaptor and then use a cheap power bank from amazon etc.

 

[Pukmeister]

Thanks for the link above. I’ve an old Keis vest I have used only once, I couldn’t be bothered to faff about with it using a bike power lead. Just ordered a battery on eBay to start using the heated vest over winter during my daily commute as I can recharge it at work. If I ever get myself another dog it would also be handy for dog walking.

I might dig out my Keis boot insoles if I can only remember where I put them as they were bloody good at keeping toasty on the bike. I already have a heated seat and grips on my Tmax.

I've had a lot of experience with power banks, cycle camping in france, trying diffrent one, This power bank I use will give you it's true value of power, most unbranded power banks will only give 55% of what it advertises at best, also the unbranded loose its ability to hold power in there battery's quit quickly, it's charge cycle as claimed may be 2000 or more times but in reality it will be 600 to 800 before you get rid, so value for money you are far better off buying a branded power bank.
I'm no expert on these it's only because I've wasted my money to get to this point,
My power bank I us is the romoss 20000mah 22.5w,
The tec side I have no idea, what it gives me is, I can ride all day on my heated jacket and at the end of the day still able to charge my phone fully,
the only thing it doesn't do what it says it can, recharge in 2 to 3 hours hours, it takes 4 to 5 that's because it gets to 90% in 2 hours then goes onto slow charge, I think that's to give greater life to the battery cells not over charging. After 2 hours of charging you still have 90% charge
Romoss do the same power bank, same size but with a 18w instead of the 22.5w but I like the fact I can fully charge my phone in one hour, where the 18w takes a little longer, not sure if that would make the units charge last longer on a heated jacket, probably not.
It's not small but will just fit in the keis battery pocket.

Hope you find this useful, if you already have a power bank us that to see if it works for you before spending £100 on a decent one

Thank you. That fills in the missing piece, as the ‘harness’ leads are easy to find.

For anyone who is looking for the USB A ‘harness’ leads for Keise, the Keise DC plug / socket size is 5.5 x 2.1. Other garments / manufacturers use different sized DC plug / sockets. For example:

Optimate is 5.5 x 2.5mm

Powerlet is 5.5 x 2.5mm

Gerbing is 5.5 x 2.5mm

Keis is 5.5 x 2.1mm (ie smaller)

You can buy simple short lead converters for Keis to Gerbing and / or Gerbing to Keis, very easily on the web. These will save you money should you change the manufacturer of your heated clothing.

I am surprised that power bank works on your keis clothing - it says 12v at 1.5A on each of your USB-A (times it by 2 will give you the 22.5 watts) when you zoom in and the keis jacket definitely draws more than that - however, if you say it works then who am i to disagree!

Your answer has no structure, your jacket draws more than that,,,,my jacket draws 1.2a if you want exact figures so well below the 1.5a, if you plan to plug the jacket and gloves you will need to do the maths, I use heated grips, it's only my top halve I need to keep warm, worse case is, it will switch off if draws to much.

ahh yes, i assumed, obviously wrongly, that your jacket was the same as mine, as my keis draws upto 6.5A - I have the

J505 Extreme. When I was looking at getting heated clothing I asked a question to ensure the charging stator would cope with charging the battery and running my heated gear, as i was considering jacket+gloves+leggings+socks.......i opted for only jacket+gloves in the end.​

For 1.5A what jacket do you have?

J801 HEATED PUFFER JACKET​

It dose two jobs for me it's a jacket I can walk round with on cold day and goes nicely under my klim jacket when riding, like on Sunday's ride, dam cold.
I think it's over priced myself, £260 a friend of mine bought a Chinese one from Ali express £14 with 12 heated sections and 5 heat setting, I used it on Sunday for an hour, it was much better than keis, can't say what amps it draws, there's nothing on it, I would say I used my power bank and it worked great, it's a push button on the chest that lights up when on, changes colour depend on what heat setting,
got much warmer than the keis, I'm going to order one for my trip to finland, he's had the jacket for over a year now so seems pretty reliable for £14, if anyone interested in one I'll post a link
