The problem
Gloves hold heat. They can’t make it.
Your fingers are the first thing to go numb — and the cold drains your phone battery faster too. The usual fixes only solve half of it.
EmberPalm™ fixes both. Real, adjustable heat in your palm — plus a 6,000mAh battery to keep your phone alive.

FAQ
Questions, answered.
How long does it stay warm?
6–10 hours per charge, depending on the heat setting. Charging a phone at the same time shortens the runtime.
Can it really charge my phone?
Yes. The built-in 6,000mAh battery works as a portable power bank. Plug your phone’s charging cable into the USB port on EmberPalm™. How many charges you get depends on your phone and how much heat you’ve used.
Does it heat on both sides?
Yes. Both faces warm at the same time, so you get even heat whichever way you hold it.
How hot does it get?
You can adjust the temperature and see the setting on the display. Built-in overheat protection helps keep it from running too hot.
How do I charge it, and how long does it take?
Charge it with a USB-C cable. A full charge takes about 3 hours.
Can I take it on a plane?
A 6,000mAh battery is about 22 Wh, under the FAA’s 100 Wh limit for carry-on bags. Lithium batteries belong in your carry-on, not checked luggage. Check with your airline before you fly.
What’s in the box?
One EmberPalm™ rechargeable hand warmer and one USB-C charging cable.
