This will be a DC powered charger, there's is no AC/DC dual charger with enough charger output power to do what you require with high capacity 6S lipos.There are only a few true dual chargers - Hyperion Duo3 which is being susperseded by the SuperDuo (whenever it actually makes to the market), Bantam BC8DX charger and iMax B6 Duo chargers. All feature builtin balancers on both ports.

To charge a 6000mah 6S takes ~151watts of charger output power. The minimum power in these 3 chargers is 180watts per port or channel. Any of them have enough power to charge 2 6000+mah 6S lipos. The lowest amount of power is from the Hyperion Duo3 at 180watts per port, but its prob the most popular of the 3. The iMax is relatively new and had some QC probs when it 1st came out.

Hyperion Duo3 requires a 14.5+v power supply to develop full power. The typical rc oriented PS is usually 13.8v and with that, the Duo3 will only provide 160watts per port, which is still enough to meet your requirements unless you want/need to charge 6S lipos with more than ~6350mah. There's not really a high voltage (>14,5v) supply available and most power a Duo with a 30 or 40amp 13.8 supply. Here's some links -
