[Q]Confusion with chargers, cables & speed

---

Hi y'all,

I'm looking to buy some new chargers (wall charger, car charger) for my HD2 (not that this should matter, I guess it's something that applies for a lot of devices) but can't figure out which combinations of chargers & cables will really charge at 1A.

The combination of an iPod USB charger with a micro USB cable from my local store resulted in 'USB connected', and hence maxed out at 500mA. Recently also used a 1.2A car charger with a micro USB cable (both from dealextreme, being cheap =) ), and once again I got the dreaded 'USB connected'.

What do I have to buy or do in order to make my phone understand that it's not charging through USB (well, in a way of speaking) but through a wall charger?


Muchos thanks!

Edit: did some more research. Just short circuited the 2 center pins of my car charger, and now it's recognized as AC, whoo! I suppose this applies to all chargers, hence, question solved!
