Naturally, there is an LED battery power indicator but something I had never seen, or more accurately, heard of, is integrated voice notification in four languages: English, Spanish, French, Portuguese. You hear spoken alerts when the device starts or stops charging, and the Peak tells you the percent of battery level available. This is great for anybody, but it will be especially useful for visually impaired users who rely on their iPhone. As technologies like Siri become commonplace, it's nice to see a charger that embraces text to speech. Regular readers know I am also an app developer, specializing in TEXT-TO-SPEECH. My AutoRingtone app helps tell users who is calling using dozens of voices, so if you can't look at the phone, you can know who is calling without guessing which song is for which user. A lot of visually impaired users use that app, and I could see them also using the Peak from myCharge.
As the Swiss Army knife of chargers, the Peak from myCharge has earned a place in my gadget bag. Even if the next iPhone comes out, with its new 19 pin connector, the extra USB port will ensure I'll always be able to stay charged.
