It does not draw 2 AMPS.
The friggin thing can be powered via a computer's USB port.
BUT... they do suggest using the 5V power cord with it.
Power Supply(Adapter): DC 5V 2A (Providing more stable electric current)
While yes its a 2A adapter, from the looks of it, it nearly exactly the same charger my Droid-X had which also said 2A. I was again, able to charge my Android by my USB computer port on my laptop.
My SGN (Samsung Galaxy Nexus) charger is a tiny little thing also says its 2A output on 5V. Not over those wires supplied with it.
The guy is an idiot... I'm sure his TV was nearly ready to puke anyway. I mean hell if Hard Drives can be USB powered, they have surge current *WAY* up there... he was doing it wrong.
