Hey guys,

Just recently bought a UPS and found out that it shouldn’t be used with an extension cord on either side.

My three questions are:
1. Can I use an extension cord and if so which one should I use?

2. Can the connect be as follows - wall socket>extension cord> Double adapter>UPS?

3. Can I use a 4 port power strip to the output of the UPS

The UPS IS LISTED BELOW:

I currently have a normal 10 ft extension cord bought from the supermarket - it has the markings ordinary duty 250/440 V

Thanks guys

Technically it *can* be done. But you are taking a big risk in 1) damaging the UPS itself, 2) damaging a circuit in your home, or 3) in worst case, burning your home down.

Your best safety margin is buying a 12 or 10 gauge cord if you are not a handyman and don't know how to add a grounded power outlet to your room (it's so easy but people pay a handyman $100 or more to do it). But again, I'd never do anything outside of what the manufacturer recommends. Your hardware, your gamble! I will say this: if a thunderstorm were around and you go with the extension cord, I'd shut that UPS off.

I have read a lot of forums prompting it can be used but I’m unsure on the specification of the extension cable? Also there are other questions I asked, hoping to get answers to those :)

1. Already answered.

2. See #1.

3. If the hardware you are running on that power strip plugged into the UPS does not draw much power and you do not plug it into the battery backup part of the UPS and instead directly into a non-backed up input, you should be fine. In other words, do not put a PS4 and TV or monitor on that power strip plugged into the UPS.

But back to #1 and #2, UPSs need to go DIRECTLY into the wall outlet.

Extension cords are not meant to be permanent. Sure no one can stop you but it is a fire hazard. I know commercially per the fire code, they will red tag it (may differ depending on location). Also keep in mind that extension cords and power strips will void equipment protection policies from the ups manufacturer. They would also deny warranty on the ups.

^^Yep. Any protection coverage Cyberpower promises from their UPS ruining your hardware will be voided using an extension cord if something goes wrong. All we can do is give advice. If I didn't know how to drop in a new outlet, I'd rather rearrange my room as necessary.
