<body class='hmmessage'><div dir='ltr'>On the most recent Hacker Trip To China, we visited a factory that makes AC power strips. Many of them have USB connectors, with USB power supplies built in. They design them, as well as manufacture them. I don't think they measure any with batteries, though. But, if you like, I could connect you with that factory.
