Samsung

Sharing is caring, folks, and that?s why Samsung has created something that?ll help you share your phone or tablet?s battery life. The company has introduced the power sharing cable, a two-way micro-USB cable that can use power from select Galaxy smartphones and tablets to charge any other device with a microSD charging port. Samsung?s obvious primary use case is charging your Gear S smart watch using your Galaxy S5?s battery, but it should be able to work with any device.

 

The accessory pairs with an app that will allow you to dictate how much juice is being sent over, so if you only want 25% of your power to be dedicated to charging another device you can make that change quite easily.

So instead of just your phone or your watch not quite managing to last a full day, use one to charge the other to guarantee that neither will? :p

...charge any other device with a microSD charging port. 

 

Pretty sure they mean MicroUSB...  :rofl:

Is this actually useful?

Probably in very specific situations. 

 

If you needed to charge a phone and you were in the middle of nowhere and only another device that had a micro USB port...

Well, say your are low on phone battery but your watch was fully charged.  Use your watch to give the phone a little extra juice.  Cool idea, but only useful in very specific situations.

DOH!  :)
