Heated Jackets Not Charging Troubleshooting Guide

“Yeah, it’s a heated jacket I bought last year for my mom, and she likes it very much. But what out of her expectation is this jacket cannot generate heat when she plans to wear it this winter.”

Heated jackets have become increasingly popular for those who work outdoors in cold temperatures or engage in winter activities. However, some users may experience issues with their heated jackets not charging properly. In this troubleshooting guide, we will discuss common symptoms and potential reasons for a heated jacket not charging, as well as provide tips for resolving the issue.


Normally, issues with a heated jacket not charging can be classified into two categories: apparel-related issues and battery-related issues.


  1. The press button cannot flash in red/white/blue light with a fully charged battery, even after pressing it for several seconds.
  2. The press button flashes in red light when a fully charged battery connects to the jacket, but it cannot flash when you press the button for 3-4 seconds.
  3. The battery LCD shows 0 or has no display indicator when a fully charged battery is connected to the jacket, but the battery can charge a mobile phone.
  4. Loose wire connection on the heated jacket to make the apparel out of work.


  1. The battery needs to take more than one day to fully charge.
  2. The battery cannot be charged, and even cannot power the heated jacket and mobile phone.
  3. A fully-charge battery remains lower power after one hour of using a heated jacket on low level, and the apparel could not turn on.


What causes a heated jacket not turning on has a lot of reasons. Here we conclude some common reasons.

Internal reason

Some manufacturers may pay less attention to detailed design on heated jackets, which brings users terrible experiences. Additionally, troubleshooting issues can arise if users do not follow the apparel's user manual. For example, some users may not charge the battery regularly.

External reason

Heated jacket should avoid wet

Normally, the weather or temperature would degrade the use of a heated jacket. For instance, extremely cold temperatures may hinder the battery's functionality. Similarly, wet weather conditions, such as rainy days, could potentially damage the battery or heating elements.


It’s simple to make a diagnosis and solve the issue of heated jackets not charging.

Firstly, check to see if the battery is fully charged. If it is, the next step is to check whether the battery port is correctly inserted into the cable on the heated jacket. Occasionally, defects in the USB port may lead to loose wires, preventing the heated jacket from turning on.

Secondly, if the battery is fully charged and the USB port is functioning normally, please re-plug the battery into the heated jacket and check if the press button flashes. If it still does not work, we suggest attempting to charge your mobile phone with the battery to determine the cause. If the battery can successfully charge the phone, the issue may lie with the apparel. 

If it can not normally charge the battery, there may be something wrong with the apparel. Instead, it could be the battery issue. Alternatively, if available, trying an extra battery could also be a helpful troubleshooting step.

Lastly, if the above steps cannot resolve the issue, it may be time to reach out to the customer service team for further assistance. They may be able to offer additional troubleshooting advice or recommend repair or replacement options.

All in all, a heated jacket not charging can be a frustrating issue, but it is often easily resolved with a few simple troubleshooting steps. Please follow this troubleshooting guide to help resolve the issue. Additionally, remember to refer to the heated jacket instructions to ensure optimal performance.
