Is it easy to replace my charging cable?
If you are using a battery-based hand warmer, then we have good news and bad news. The bad news is that most retailers don’t seem to offer the option to order just a new cord in the event that you need a replacement. The good news is that many hand warmers charge via the same input port as phones so ordering a replacement charge cord is pretty no hassle.
These types of ports mean that some of these phone warmers have the option to act as a phone charger as well as a hand warmer, which is a nice added plus. So while replacements can be limited you should be able to easily find a new cord that will do the job all the same.
