HTC Chargers – Mini USB or EXT-USB

Tuesday 3rd March 2009 by Andy in Mobile Accessories.

The one thing we get asked about quite often with HTC devices is about the charging connection. Older HTC models came with accessories that had a standard Mini USB connector, where as the more recent devices use EXT USB, they look similar, but whats the difference?


Mini USB on the left, EXT USB on the right.

EXT USB is a connector type that is specific to HTC Devices and features a powered USB and Headset connections in a single combined connector. This new type of connector lets you charge, sync and use audio devices all through the same port (though not necessarily at the same time).

The EXT USB port is backwards compatible with Mini USB which means that you can use older Mini USB accessories with newer EXT USB handsets, but you not the other way round.

HTC still have stock of Mini USB accessories, which is why some genuine HTC replacement cables or chargers are not exactly the same as the one that you got in the box with your phone. If you order a replacement and its not exactly the same as your old one, don’t panic, it will still work perfectly fine.

    If your phone has the connection shown on the left, then no, you won’t be able to use a the new type of connector on an older handset, but you can use older accessories on newer phones.

    Not that I’m aware of, most ext accessories are wired up differently, so even using an adapter like the one you’ve mentioned wouldn’t necessarily mean the accessioy would work.
