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. On the other side, it would cause some troubleshooting if users cannot follow the apparel user manual. For example, some users don’t 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 example, the extremely cold temperature would affect the working of the battery. And wet weather, like rainy days, maybe 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. Sometimes the USB port may have some defects to cause loose wire and make the heated jacket not turning on.

Secondly, if the battery with full power and a normal USB port, please re-plug the battery to the heated jacket and see if the press button flash. If it’s still not working, we suggest you could charge your mobile phone with the battery to find the cause. If it can normally charge the battery, there may be something wrong with the apparel. Instead, it could be the battery issue. Or it’s a good try to use an extra battery (if you have one).
