The packet problem

120 packets, or one bean.

Shake-and-heat warmers work once. When they go cold they go in the bin, and the next cold morning you open another pair. Plug in your own winter and see what that adds up to.

How it works

Charge it. Press it. Pocket it.

No apps, no pairing, no settings menu. It's a warm stone with a button on it.

first,

Charge it

Plug it in with a USB-C cable, the same kind most phones use now.
then,

Press it

One button turns it on and picks the heat: low sits at 50°C, high at 60°C.
and finally,

Pocket it

Hold it, or drop it in a coat pocket. It's about 10 cm long and weighs 150 g.

oh, and

Phone on 5%? Your hand warmer has you covered.

The same 4000 mAh battery that keeps your hands warm can top up your phone. Plug it in, and keep walking.

(Got product for free): Overall not a bad product, while it can be annoying to remember to actually charge the warmer it's reliably held it down for me through some tough situations.

Questions

Asked, answered.

Something we missed? Send us a note.

How hot does it get?

There are two settings: low at 50°C and high at 60°C. High is properly hot, so don't hold it against bare skin for long stretches, and don't sleep with it switched on.

Can it really charge my phone?

Yes. Inside is a 4000 mAh battery, and you can plug your phone into it for a top-up. It's the same battery that makes the heat, so charging your phone leaves less for your hands.

How do I charge it?

With a USB-C cable and a standard 5V / 2A phone charger.

Which pack should I get?

Single: one bean, any color. Duo: two beans in the same color, one for each hand. Trio: one of each color, which makes an easy gift. Quad: two pairs in the colors you pick, and the lowest price per bean at $24.

How big is it?

104 × 49 × 30 mm and 150 g, about the size of a bar of soap. It fits in a coat pocket.

Is it safe?

It's CE certified and runs on a lithium-polymer battery. Charge it with a standard phone charger, keep it away from young children and anyone who can't feel heat well, and stop using it if it's ever damaged or swollen.

Is there a warranty?

Yes, every cozybean comes with a 1-year warranty.

How much is shipping?

US orders of $40 or more ship free, after any discount. Below that, Standard shipping is $8 and Express is $15. You'll see the options for your address at checkout before you pay.

Can I return it?

Yes. You have 30 days from delivery to send it back. Email us with your order number and we'll walk you through it.
