FAQ Section
FAQ Section
Q: My device only requires 5V 3A. Is it safe to use this 8A adapter?
A: Yes, absolutely. A device will only draw the current (Amps) it needs. Using an 8A adapter for a 3A device is perfectly safe and actually means the adapter will run cooler and last longer since it isn't operating at maximum capacity.
Q: Does this adapter come with the power cord that plugs into the wall?
A: No, this listing is for the adapter brick only. It uses a standard 3-pin (C14) inlet. You can use a standard desktop computer power cable, or purchase one directly from our store via the link above.
Q: Will this fit my CCTV camera?
A: Most security cameras use a 12V supply, while this is strictly a 5V supply. Please verify your camera's voltage requirement before purchasing. The physical plug (5.5x2.1mm) is an industry standard often used in 5V IP cameras and networking gear.
