Review on Adapter Alienware Precision GA240PE1 00 ETTECH by Rafael Calderon

Works on Dell G7 17 7700 with no issues. There are no problems with overheating or undervoltage yet. Slightly larger than the original but to be honest it's negligible. There's a slight difference when comparing side-by-side, but if it had come from the factory I never would have known. One thing I noticed is the discharge rate, which is much faster than the OEM. The OEM light ring stays on for a few minutes after it's turned off, but aftermarket it's 30-40 seconds. The jack seems to be a more secure fit than the OEM. Great as a backup or to leave in the office. This may be the one I received, but again the cord length, which is 2 inches shorter, is negligible.
