Battery Basics

The battery used in heated clothing is just as important as the heating elements. When considering heated apparel, the weight, voltage and runtime of the battery are a factor that you should absolutely consider. Let’s have a quick look at these factors and why they are important:

Battery Weight

This is a big consideration because an overly heavy battery can impact the comfort and functionality of the jacket. Large batteries can get in the way and make the jacket feel cumbersome and uncomfortable. A low profile, lightweight battery will not get in the way when you are out and about.

Battery weight will vary depending on the product. While a Gobi heated jacket comes with a battery that only weighs 8.39 ounces, a Ravean jacket battery comes in much heavier at 1.06 pounds. In general, the lighter the battery the better. Check the specifications of any jacket (or any other heated garment) to determine the battery weight and avoid those with a heavy power source.

Battery Voltage

The voltage not only determines how warm the jacket will get, it is also directly related to the weight of the battery. The bigger the voltage, the heavier the battery. The battery voltage will vary depending on the manufacturer and the product type but in most cases, it will be a 3.7 volt 5 volt 7.4 volt or 12-volt battery.

Items such as heated socks tend to have smaller 3.7 batteries while a jacket may use a 12-volt battery. We recommend sticking with a 7.4-volt battery for jackets if possible as a 12-volt battery can feel a bit heavy.

Battery Runtime 

Another major factor with heated clothing batteries is runtime or how long they will keep your clothing warm. The voltage of the battery will impact runtime so there can be a trade-off between weight and runtime.

As an example, Gobi Heat, which uses a 7.4-volt battery claims they get 10 hours on low setting, 8 hours on medium, and 6 hours on high while an Ororo jacket which also uses a 7.4-volt battery gets 3 hours on high, 6 hours on medium, and 10 hours on the low heating setting.

The importance of battery runtime really depends on how you use your heated clothing. If you plan on being out in the cold for an 8-hour workday, a long runtime will be more important than if you only use it to shovel your walk after a snowstorm.

Battery Charging

Charging a heated jacket battery is as simple as plugging the battery into a standard wall socket or in some cases, a car outlet. Charging time will vary depending on the product and manufacturer but in expect to need 3 to 4 hours of charging time to fully charge a heated clothing battery. Some brands, Gobi is an example, come with a car outlet charger so you can charge your heated clothing on the move.

Mobile Phone Charging

Some heated jackets now come with the ability to charge a mobile phone using the heated jackets battery pack. Not all brands have this functionality, Ororo and Ravean are examples of the coats that will charge your phone. However, it should be noted that this will lower the runtime of the battery so make sure you consider the implications for battery life when charging your phone.
