What's the Difference Between USB mini-A and micro-B USB?

Is there any speed/functional/power difference? They are almost identical in size...why the variant?



All I ever really needed to know, I learned from watching Star Trek.

they are thinner for thinner devices and they are for USB ON the GO devices.
there's a further or subset set of rules for plug orientation for that group of devices

I'm pretty sure the micro allows device identification to allow power beyond the 500 mA standard to allow a phone ( or device) to charge faster.

Are you SURE you have mini-A cables? mini-A is a deprecated standard.

If you have a bunch of cables laying around, they are more than likely standard A to mini-B.

I think a lot of cell phones are moving to the micro-B standard (at least I hope so since my current phone is micro-B and I don't want to buy another charger and cable when I replace it!!).

Of course, the iPhone connector is anything but mini or micro.

The EU has gotten all the cell phone makers to agree to standardize on one type of connector, the micro.

Is that the micro-B or the micro-AB?

According to Wikipedia, micro AB: Wikipedia - USB

The cellular phone carrier group, Open Mobile Terminal Platform (OMTP), have recently endorsed Micro-USB as the standard connector for data and power on mobile devices.[23] These include various types of battery chargers, allowing Micro-USB to be the single external cable link needed by some devices. As of January 30, 2009 Micro-USB has been accepted by almost all cell phone manufacturers as the standard charging port (including HTC, Motorola, Nokia, LG, Hewlett-Packard, Samsung, Sony Ericsson, Research In Motion) in the EU and most of the world. Worldwide conversion to the new cellphone charging standard is expected to be completed between 2010 to 2012.

In addition, on 22 October 2009 the International Telecommunication Union (ITU) announced that it had embraced micro-USB as the Universal Charger Solution its "energy-efficient one-charger-fits-all new mobile phone solution", and added: "Based on the Micro-USB interface, UCS chargers will also include a 4-star or higher efficiency rating—up to three times more energy-efficient than an unrated charger."[24]

I bought a handful of little pigtail adapters on eBay that convert the mini to the micro (or the micro AB to the micro B, I'm not sure!). They have a lanyard on them so you can loop them onto the cable they're adapting, and they won't get separated.

I think they cost a buck apiece and were quite worth it in my opinion.

...and that's not counting the proprietary USB connectors for stuff like Sony and Nintendo joysticks and memory-cards; Nintendo DS and Jabra power-adapters; automobile alarm boxes and testers...
