Battery works

Not much to say apart from it is a battery, it takes a charge and it does power the vest and gloves. I only bought this as a backup for when I don't take power direct from the bike so can’t say anything about its endurance. It’s compact and seems to do the job.

Great jacket

Love the heated jacket go a size smaller than the size you normally get, having said that it's great and the battery is good to keep you warm when off the bike.

Useful addition

adding a battery to the apparel is useful when at home or when outside at an event but the 2 hour charge is too little for the usability. 4 hours would be perfect.

Keeping warm off the bike

This is great if you park up your bike and take a break or if you are unfortunate to breakdown on a motorway and have to wait the other side of the barrier away from the bike

Only tried it briefly, seems to work okay.

I fully charged it but after only a short while the charge dropped. Haven't used it yet apart from a brief test. Quite expensive to buy.

Warm again!

I use Keis motor cycle inner gloves for dog walking as suffer with Raynauds. They’re my life save but stopped working as I use them so much. Customer Service lady was so helpful & suggested I order replacement cable & battery, advising me which ones, then I’d need to order online. They came promptly & I was very happy to have warm hands again!

Don’t buy the battery

Bought the new release battery in December for £90. Used it with the jacket and only got 1hr 20mins of use out of the battery. No good what so ever to anyone that. I bought a cheap heated jacket of eBay and I get far longer from that one.

Love the jacket when it’s plugged directly in to the bike but the battery is a big big let down

Hey David!

Thanks for the feedback! Our 5000mAh battery is for short use off the bike due to it being 12v there is quite a strong power draw from our garments. The garments found on eBay are usually 7.4v and therefore may last longer but output would be lower and using thinner heating elements.

If you are using the jacket on a motorcycle we would always reccomend using it plugged in direct to the motorcycle battery.

Many thanks!

Extends the use of my heated Jacket

I jumped at this battery when annouced.
The jacket is great when riding and plugged into the bike.
Now I can use the jacket when out on foot in chiily conditions.

Battery pack

Excellent accessory and saves having wires dangling. Especially nice to have battery level display. Only downside is the weight.

Does what it says on the tin

Carefully posted and received, so far works fine. Nice power display. Recommend giving it a full charge before using

Works a treat

Very pleased with the battery, connections could be improved for using as a normal jacket as the wires hang down. I need to add a pouch so battery sits higher up.

Jacket battery power

Battery seems great. Did not come with a cable to be able to connect to the heated jacket. Looks like you have to have an adapter to use as you need two male plugs. Adapter plugs are out of stock! Should be a consideration on Keis part !

Answers

Frequently asked questions

Can I use the 5000mAh battery to power more than one garment at a time?
We do not recommend using the 5000mAh battery to power multiple garments simultaneously. While it technically supports 12V output, it has a 6A maximum current limit, which means powering more than one garment, such as a jacket and gloves together, can quickly exceed this limit. Doing so can lead to significantly reduced run times, performance drops, or even damage to the battery. For multi garment setups, a direct bike connection is the safer and more efficient option.
How long does it take to fully charge the 5000mAh battery?
When using the KEIS 30W Fast Charger, sold separately, the battery can fully charge in approximately 3 to 4 hours, depending on the remaining charge and ambient temperature. Using a lower wattage charger or non fast charging USB source will increase charging time significantly. The USB-C port enables fast input, and the included cable ensures you have the right connection straight out of the box.
How do I know how much battery life is left?
The LCD capacity display shows a real time percentage readout of the battery’s remaining charge. This is far more accurate than traditional LED indicators and allows you to better plan when to recharge, especially helpful on longer rides or trips where access to power may be limited.
Which KEIS garments is the 5000mAh battery compatible with?
The battery is compatible with all 12V KEIS heated jackets, bodywarmers, vests, gloves, and trousers, including the latest ULTRAFLEX and EXTREME ranges. However, run time varies significantly depending on the garment’s power draw. For example, bodywarmers may run for up to 10 hours on low, while high power jackets like the J505 EXTREME may run for only around 1 hour on medium power.
What does the E2 error code mean and how can I fix it?
This error code is present when the battery is being overcharged with a current higher than 6A, which is the max deliverable power of the battery. In order to solve this battery error code, simply reset the battery by holding down the power button. Ensure your charger is not short circuited, as this could cause a spike in power delivery, and if the issue persists contact our customer service team.
