Rated 5 out of 5 by from Very High QualityThese are definitely high quality. I haven't had one fail yet out of dozens purchased. Higher amp rating than most. Similar supplies can be found cheaper from other vendors, but they aren't as reliable as the ones from Parts Express.

does it fit Lepai amp without modification?

Asked by: gychang
The Lepai amplifier requires a 2.1mm x 5.5mm plug, so this will fit but it may have an intermittent connection.

Asked by: TaylorJ
You will need a power supply that produces an output of 17 VDC at 1A or higher. Unfortunately we do not have a suitable power supply for this application.

I need a replacement power cord for a Halloween animated full size (6 ft) figure (Edwardian Butler). When powered, he talks and moves and is motion activated. Would this cord work for this purpose?

Asked by: MikeR10
This power supply is 12vdc rated at 5amps and uses a 2.5mm connector. Review the requirements for your figure and make certain it accepts the proper voltage, current rating and tips size as described.
