Where can I get a decent 5V 2A wall charger?

I've searched through ebay, amazon, dealextreme, ncix, infonec, newegg, no avail yet.

If you can order this one, get it. It can charge 2 phones at a time and is considered a rapid charger.

T-Mobile rapid charger

If you look at the 4th picture the "user instruction" clearly says it's 300-500mA. This item is mis-advertised...

Its output current is 500mA... and it seems a little weird to be honest...

After a second read, seems that the "user instruction" is not for that device. The picture on the instruction looks similar but is actually different from the device. So maybe the seller got things mixed up.

Idk what the output is tbh. But I have several of their chargers and they charge fast. Faster, way faster than the slow stock charger.

If the T-989 circuitry is anything like the ATT Samsung Infuse, ATT Samsung GS2 or the Galaxy S1 variants the charging current is LIMITED by the ROM & hardware and the MAX current for the device limited by the chipset is ~600mah so a higher current charger won't help, it's probably placebo effect.

I believe Entropy512 on the ATT GS2 forum has done some heavy investigation into the integrated chipsets in the phones used for charging these devices and has confirmed these limitations using the manufacturers chipset specs.

He was able to jack up the max charge current about 100mah or so on a couple devices in the kernel. But a larger charger is going to make very little if any difference. The phone automatically current limits to prevent overcharging the battery or at worse an explosion. These batteries are very dangerous at too high current.

Bottom line is you could use a 10amp charger and the phone will only charge at it's rated capacity which a WAY WAY below 2000mah and probably no more than 700mah on these phones.

I'm on the stock rom and these chargers are better than the stock though. The car charger version can charge the phone very fast (within an hour). I know from use that these can charge a stock gs2 faster than the stock charger. I got them because the sensation took 8days 22minutes and 43 seconds to fully charge. And I kept them for the gs2.
