1. How long does it take to charge a heating pad?
Heated for 30~50 minutes, the heat can be preserved and kept inside the hydrogel and makes the pad warm lasting for 30~40 minutes. 
2. When the heating is completed, how long does the warmheat last?
Under the room temperature 25°Ϲ, the pad can be kept warm for 30 minutes,  and you may cover the heating pad with a blanket for prolonged heating. 
3. Why do we recommend you keeping the pad in a vacuum bag we provided if you do not use it for a long time?
The main material of hydrogel is water. Under normal condition, water will gradually evaporate, in addition, the heat-resistant of nylon temperature is 60 degrees, each heated or not using for a period of time, the water will gradually evaporate. therefore, we recommend if a period of time not using the heating pad, please cooling the pad then stored it in a vacuum bag to prevent moisture evaporation, It also prolongs the use time of the product. 
4. How long does the lifespan of the heating pad?
Water is the main component which constitutes a heating pad， by each heating, the pad will reduce 1g，  and the water will run off 1g per day as well。
The new heating pad is 1,350g，two pads can be used 360 times in a year， and about one year later， the pad is about 900g left.。
When the heating is completed for 20 minutes only, it means that most of the water has been evaporated, and the heat storage time is relatively short. Under this condition, we recommend replacing the new pad.
5. What kind of reason causes the power can't work properly?
1. Please check the golden pin plate is right attached to the magnetic plate on the white thermal temperature control device.
2. If the pad is too thin causing the thermostat for both sides couldn't get close each other,  it is recommended to replace the new pad to make the heating process get back smooth.
6. Can this product be used in many countries?
This product adopts international voltage, you can use in Taiwan 110V, Japan 100V, U.S.A. 120V, China 220V, British 240V.
7. Does AC current produce electromagnetic waves? What is the effect of electromagnetic waves on human body?
Power lines, electrical wiring, and appliances that work on alternating current -  all produce electric and magnetic fields.
We see that Electromagnetic radiation emitted from laptop computers, cell phones, and other electronic devices can be harmful to our bodies. Many studies have revealed a link between the use of these types of technological devices and various forms of illness. Short-term health effects like headaches, long-term health effects such as concentration or memory loss, sleeping problem...
8. How to reduce live in the electromagnetic wave environment?
Technology plays a major role in most people’s lives. While you can certainly try live without electric devices, it might be difficult. 
1. Avoiding the effects of electromagnetic radiation like avoid charging cell phone on the bed.
2. When the electrical appliance is not in use, it is better to unplug the plug to prevent the indoor environment from electromagnetic waves.
9. Why do we claim that Warme Mini is a zero electromagnetic wave product.
The cordless heating pad is taken out after being heated by the thermal bag, there without electric current passes through during use, therefore, there aren't electromagnetic waves are generated, and the negative health effects on the human body.
10. What is the far-infrared?
Sometimes when you step out into the sun you can feel warmth overcome you from the inside out. This feeling is caused by far infrared rays, an invisible light on the opposite side of the spectrum of harmful ultraviolet rays. It is the same light that plants photosynthesize in order to feed. This plant dependency of far infrared can be found in the human body as well level. That warm resonating feeling you get from the far infrared rays speaks to our bodies need for rays of sunlight. That warm feeling can be harnessed to improve our wellness. The sun, our bodies, and our hands are always emitting FIR. In the past, it was this discovery that leads to improving our health.
