Regarding these and the use og Synology silver plugs:
After personal experience i must strongly recommend that these coilpacks aren't used with any plugs with a lower resistance than stock, as they won't be able to use the energy they generate and WILL cause the coilpacks to catch fire.
Okada have taken notice to this and has put a warning inside their products packaging to avoid there plugs being matched with the wrong type of plugs
