If you use a heated jacket or other attire, then you are all too familiar with being locked in to USB battery packs with barrel connectors. While I'll grant that it is typically more durable, it is also inconvenient at the same time. That's where this charge adapter comes into play.The listing shows DC5.5mm connection and down below it also lists "Includes DC 3.5-4.0mm output plug that fits most standard heated clothing power connections". There was no adapter for 3.5-40mm included.In my case, I have a 7.4v heated jacket that I wanted to be able to utilize standard USB battery packs with.Sadly, I misjudged the plug size on my jacket as it's smaller than I had thought, even smaller than what the adapter may have offered. So I am unable to test out the adapter and really put it to use.At most, I did plug in the adapter to a USB battery pack and it showed 9.0v.When I find the appropriate adapter to go from this size to my jacket, I will post an update.
