“It makes a difference when the cold sets in.”

Market, patio, parking lot, the late trip home: that’s when adjustable heat really pays off.

Use cases

The situations where a fully charged spare battery makes the difference.

10,000 mAh Power Bank Long hike Replace the battery that is starting to run low with one that was charged before you left.
10,000 mAh Power Bank Backup in your pack With 2, you have one battery connected to the jacket and one fully charged spare.
10,000 mAh Power Bank Another heated garment With 3, you also get a spare for another heated garment or a very long day.

Why this choice

One fully charged battery does the job on a normal outing. Packs with 2 or 3 make you less dependent on a single charge.

With 2, you can switch without cutting the trip short. With 3, you also get a spare for another heated garment or a very long day.

1 battery One full charge.

For a normal trip, one fully charged battery does the job.

Frequently asked questions

Your questions before you order.

Straight answers to the questions that often come up before ordering.

How can I be sure it works with my jacket?

Three points, all of which can be checked before purchase: the voltage, the connection port and the model of your heated jacket or heated vest. If all three match, this external 10,000 mAh battery takes over from your battery — or becomes your reserve battery. If you are unsure, send us your model before ordering and we will confirm compatibility.

How long does it really last – not just on paper?

The only honest answer is that it depends on the garment you are powering, the selected heat level and the outdoor temperature – a low setting always lasts much longer than a high one. That is why we state a real capacity, 10,000 mAh, instead of a single runtime taken from marketing. Rule of thumb: save the high setting for the toughest moments and let the low setting last – and for very long days outdoors, the packs with 2 or 3 batteries make the question irrelevant.

Is one enough, or should I choose the pack of 2 or 3?

For a regular trip, one fully charged battery does the job. The multi-pack solves another concern: relying on a single charge. With 2 units, you have one battery connected to the jacket and one fully charged spare, and you can swap without cutting the trip short. With 3 units, you also get a spare for another heated garment or a very long day.

How do I store the battery?

Keep the battery dry, clean and protected from high heat. Keep each battery dry, and never use a damaged connector on either the battery or the jacket.

Can I use it with a damaged connector?

Non. Keep each battery dry, and never use a damaged connector on either the battery or the jacket.

What do I need to check before I connect it?

It powers compatible heated jackets and heated vests according to voltage and connector. If unsure, compare it with the original battery before ordering.

What if the battery does not fit my equipment?

You have 90 days to request a return in accordance with the store’s current return terms. Customer support replies within 24–48 business hours if you are unsure.

What if I have a problem after purchase?

This is the real problem in this market: customer service that is impossible to reach, and refunds that never arrive. At QUILLMORE, you get customer support with replies within 24–48 business hours, a 90-day satisfaction guarantee or your money back – the full policy is published, not hidden – easy exchanges and a 5-year warranty included (optional lifetime upgrade at checkout) alongside any applicable statutory consumer rights. Write to us: Messages are read, and you will get a reply.

Final decision

Do not let a single charge control your day.

Choose the quantity, check that the battery is compatible with your jacket, and head out with the spare fully charged.
