Most tech start-ups in the field of mobile phone battery preservation are looking at innovative ways to charge people’s phones. From the [Donor Cable](https://www.prote.in/en/feed/2014/06/donor-cable?ref=protein.xyz) \- a bracelet that siphons power from another phone, to [trousers that charge your phone](https://www.prote.in/en/feed/2014/06/charging-trousers?ref=protein.xyz) as you walk, developers are trying to push things forward; to the point where [prototypes are charging using ambient noise](http://mashable.com/2014/08/14/charge-smartphone-with-sound/?ref=protein.xyz).  
  
But for every inventor there’s a businessman and businessmen find solutions too; only these solutions often take a more direct, lucrative route to fixing problems. A new service called [Doblet](https://www.doblet.com/?ref=protein.xyz) plans to place portable battery packs in popular bars and restaurants, with users paying to use them. By paying a flat annual fee of $30, members can walk into any venue that stocks Doblets and recharge their phone. Those who aren't members can pay $3 for a single charge. Members can find the nearest Doblet through the companion app.   
  
Not only is this likely to be a money-spinner for Doblet but bars and restaurants can also use the service to attract passing trade for themselves.
