I can't say whether the Dell power unit is supplied by IGO or not. It certainly does not look like the IGO Juice--it is larger and heavier. It also does not have more power--it is only 65 watts. The documentation specifically states that it is not enough power to charge the batteries on higher power computers such as the 8500 or D800.

Also the cords are lighter weight than the IGO cords.

Another difference is that the cord between the power brick and the computer does not detach from the brick, so this power supply is only usable with Dell computers that use the same plug as the D600.

Another difference is that the peripheral power port is at the end of the cord where it plugs into your computer. This means that you can only plug one item in at a time. If your computer is plugged in, you cannot simultaneously recharge your cellphone, and vice versa. Thi IGO juice has the peripheral power port in the middle of the cord making it possible to power both your computer and your cell phone at the same time.
