Doblet is a new Y Combinator-backed startup that aims to provide mobile device charging everywhere you go. The startup is currently working with businesses around San Francisco to get its charging system installed in bars, restaurants, and other businesses where people stay for extended periods of time.
Doblet users can sign up for the service, order a portable battery for their device, and then pay to get their device charged. The cost of this service is either $3 for a single full charge at any establishment supporting Doblet, or $30 for an annual pass that lets you charge an unlimited number of times.
The company says that once another month has passed, it will have its charging systems installed in 50 locations around San Francisco. Right now, three businesses are working with Doblet, but others are lined up.
