It’s that time of the year again as Samsung starts to make changes as their new phone models are coming out. With the release of the Samsung M300 and M510 to Sprint also came the release of different chargers and data cables. Unlike the older Samsung chargers, the M300 and M510 charger are slightly slimmer, yet wider than its predecessor as featured below in the travel charger(Samsung Product ID: TAD437JBEB/STD).

This particular charger was compatible with the older and newer models such as the Samsung i607 Blackjack, SCH-U740, and the more recent Upstage M620. The difference with the newer proprietary port is minor. The minor change in the charger includes a shorter mini USB plug in comparison. At the moment, the official Samsung website does not have the OEM travel charger for either the M300 or M510. However, other websites do have the OEM charger available pictured below in the car charger (Samsung Product ID: CAD300SBEB/STD).

Samsung seems to change the ports on a yearly basis, unlike to its competitor Nokia. Additionally, LG Electronics also follow the same path. For older models such as the LG VX9800, VX8300, and the CU500, the ports are all similar. However, LG also has a different charger available with a much smaller USB plug for the Chocolate VX8600 and enV VX9900.

After doing research, we are unsure as to what is the reason for changing the port for the M300, M510 and possibly other upcoming phone models. The change may possibly be connected to the designs of the new slender models. However, it may also be a move to add and introduce another full line of Samsung accessories.

Why is it that Samsung and other manufacturers always change their ports? Unlike Nokia which only introduced 2 different ports in the last decade.
