*= Personal test with a 10.000 Essengar power bank. (personally I use a 26800mAh power bank that lasts over 8 hours on high)
The temperature is more an indication than an accurate number…
For example if you set the vest at high it makes a really huge difference what the outside temperature and what you are wearing on top of the vest.
While you can wear the vest the way you like my personal preference (and suggestion) is, to wear it on top of a t-shirt. Over that you wear a sweater, jacket, etc
If you don’t you will mainly be heating outside air instead of your body. Compare it with heating your house, you don’t do that with all doors and windows open.
False advertising? Nope, just being honestly speaking from experience. I always use the vest on high under a sweater and while I can’t give you a scientifically proven number on how hot it feels, I can state I feel a real significant difference.
Fun fact: I’ve read a story of someone cutting her winter heating bill in half by wearing such a vest because she could turn the thermostat down without feeling cold.
Smell
The new vest has rubber smell. That will be almost gone after a day of using on high. The second day it will completely disappear.
