Can I Use Any Power Bank with Heated Jacket?

Heated jackets have come a long way since their invention years ago. While they may have faced skepticism in the beginning, their widespread popularity today speaks for itself. Now, you can find heated jackets almost everywhere, especially in colder regions.

Unlike traditional jackets, heated jackets are powered by batteries and equipped with heating elements to generate warmth. Because of this key difference, a common question arises: Can different types of batteries be used to power heated jackets?

How do heated jackets work?

Heated jackets work in a similar way to heated blankets, using built-in heating elements to generate warmth. Most models use carbon fiber elements, which are lightweight and provide even heat distribution for efficient, all-over warmth.

These jackets also include a convenient pocket for storing the battery. Once the cable is plugged into the battery port, power is transferred to the heating elements, allowing the jacket to begin producing heat within seconds.

Can I use any power bank with heated jackets?

As mentioned earlier, the power bank is essential to a heated jacket’s performance. Without it, the jacket loses its functionality. Because of its crucial role, many users wonder: “Can I use other batteries with my heated jacket?” or “Is it safe to use my phone's power bank?”

In the heated apparel industry, most jackets come with specially designed rechargeable power banks to ensure safe and reliable performance—just like those from Venustas.

At Venustas, we offer several types of power banks for heated jackets, typically featuring 5V, 7.4V, and 12V outputs. The 5V models were our earliest versions, but they’ve since been phased out as we’ve upgraded to more advanced systems. Today, our 7.4V and 12V batteries deliver stronger performance, heating larger areas and distributing warmth more evenly. (Learn more: Battery Guide—5V, 7.4V, or 12V: Which One Is Better?)

Our batteries are also designed with dual USB ports, allowing you to power your heated apparel and charge your mobile phone simultaneously. While we don’t recommend using third-party power banks with Venustas heated apparel, our power banks can still serve as regular portable chargers for your other devices.

That said, not all heated jackets are limited to designated batteries—some can run on other power sources, offering more flexibility. However, this comes with risks. Non-original batteries may lack safety features like overheating protection, which can lead to instability, overheating, or even fire hazards. For this reason, we strongly recommend using original batteries whenever possible.

How to take care of the power bank?

A power bank is composed of an integrated battery and electronic components, and improper use can be dangerous. To ensure safety, always follow these battery guidelines:

• Keep the battery away from water, and always remove it before washing the jacket.

• Avoid exposing the battery to direct sunlight, high temperatures, or excessive moisture.

• Prevent overcharging by unplugging the cable from the battery port when not in use.

• Do not use low-quality or incompatible charging adapters.

• Handle the power bank with care—avoid squeezing or dropping it.

In short, it’s best not to use third-party power banks with heated jackets. Doing so not only reduces the risk of accidents but also helps extend the lifespan of your heated jacket. For added safety and reliability, we recommend choosing brands that provide specially designed batteries. for added safety.
