I reviewed two portable Bluetooth speakerphone options earlier this year: The Philips WeCall ($145) vs. Logitech P710e ($125) . Both are square and have internal batteries and make conference calling easy. But for their ~$150 price tag, I wondered if you could get more portability and style without sacrificing sound quality.

The answer to those questions is the Harman Kardon Esquire line of portable speakerphones. Below, I take a look at the Esquire Mini which retails for $149.99 and can be found as low as $145 at Amazon or $135 at World Wide Stereoexpand full story

There’s no real hard news at this talk given by Elon Musk this week but it is certainly interesting to see the back and forth with the iPhone Engineer (Evan Wong? Didn’t quite get the name) and the CEO of Tesla. Apple is of course rumored to be an investor in Tesla’s battery Gigafactory so that makes the conversation all that more interesting. Some notes:

  • The engineer manages a big part of the hardware development of the iPhone.
  • Apple is one of the biggest buyers of batteries along with Tesla and they’ve done a lot of thorough testing
  • Chemistry, material, packaging and process affect  battery life constant.
  • Tesla buys 18650 form factor batteries and is sticking to them.
  • When musk asks about the energy density, the engineer knows not to say anything (he says he doesn’t want to get sued by his employer – to many laughs from the audience).
  • Musk assumes the battery energy density is public domain because of teardowns
  • Musk says in high production they can get to 260Wh/KG at the lowest price per kW which might be good info for those looking at the Gigafactory specs.
  • Apple likely can’t use these cells in their products because they are 18mm thick, much thicker than many of Apple’s products – or so speculates Musk

iFixit has done its usual trick of hopping over to Australia to get its hands on an iPad Air in the first time-zone to open its doors for business to bring us a look at the innards of the new device. The device is now on sale in the U.S. too, with supplies expected to be good.

No surprise that the company found little prospect of success for DIY repair, reporting that even opening the casing was a challenge: when you pack that much technology into so small a space, there’s going to be a lot of glue involved.

AnandTech dug into the FCC filings for the new iPhones to reveal that the iPhone 5s battery offers approximately 10 percent more capacity than its predecessor, while the 5c battery offers a more modest 5 percent gain. That’s a different size battery (5.96Wh vs 5.92Wh) than we’d seen in supposed 5s prototypes …  expand full story

With a gold iPhone 5S and multi-colored iPhone 5C expected on September 10th, Mophie has responded by offering a choice of five different colors for the Juice Pack Helium external battery-case for the iPhone 5/5S which we reviewed back in March.

[We] today announced five distinctive new colors for the juice pack helium: blue, purple, pink, green and red. The new matte-finish, jewel-tone cases wrap serious protection and power in a burst of color, delivering 80 percent more battery life and edge-to-edge protection against the drops, bumps and scratches of everyday mobile device use.

The units are otherwise identical to the standard Juice Pack Helium, with a 1500mAh battery that we found delivered on Mophie’s claim of between 6-7 hours additional usage.

You can pick up Mophie Helium Juicepacks at Amazon starting at $68 or on Mophie.com for $79.99 retail price. expand full story
