Need power strip explanation on number meaning

strip a...2250 joules...1875 watts...1875va
strip b...4000 joules...1875 watts...1100va

What does the joules and va #s mean?
I don't think I can answer this very well but I'll take a stab at it.

The joules rating is specific to surge protector circuits, it is basically the amount of energy the surge suppressor components can absorb before they are exhausted and can no longer provide surge/spike protection to the attached devices.

The 1875 watts just means it is a 15 amp/125volt device.

I have no idea why a power strip would list the va. This is commonly included as a rating on UPSs to indicate the continuous apparent power it can provide. The only reason I can think of a surge protector having a va rating different from the total watts is if it contains active components in the surge circuits.

Someone more versed in ac circuitry can probably clarify this and correct any errors I may have made.

When I was in my 20's, I had coffee after dinner when I would attend dinner business meetings. I would ask for an Irish Mexican coffee with heavy cream. It was loaded with alcohol
I actually just ordered a "Caramel Blondie" latte. White mocha and caramel. It's tasty!

Sorry, I'm available to answer the electrical question now!


My answer is as follows: I am a water guy. Water guys do not mess with electrical stuff because electricity happens.

Sorry, I cannot help.

What does the joules and va #s mean?

Joules is the surge protection rating. It tells you how much surge energy the strip can absorb over its lifetime before the protection is basically used up from power surges etc.. Higher joules means better and longer-lasting surge protection, but it doesn’t change how much power the strip can deliver day to day.

Watts is the real power the strip can supply to your devices. In the U.S., 1875 watts is basically the max for a standard 15-amp outlet. Standard outlets are 15 Amps. Appliances use higher amps usually. Since both strips are rated for 1875 watts, they can both handle the same total load from whatever you plug in to standard outlets..

Volt-amps is apparent power, which includes inefficiencies from things like power supplies, motors, pumps, LEDs, etc. Normally VA is equal to or higher than watts because of power factor. That’s why the VA numbers are usually more relevant to UPS units than basic power strips.

What stood out to me is that strip A lists 1875 watts and 1875 VA, which is straightforward and normal. Strip B lists 1875 watts but only 1100 VA, which doesn’t really make sense if taken literally. My guess is that the VA number is a conservative or continuous-load rating, or it applies to a specific internal component rather than the total output. A strip couldn’t actually deliver 1875 watts if it were truly capped at 1100 VA. (If I had to guess it just wants you not to plug a lot of high energy items in Strip B)

Bottom line, the watt rating tells you how much you can safely run, and both strips are the same there. The joule rating tells you how good the surge protection is and how long it will work for, and the 4000-joule strip offers much stronger protection. The VA number on a regular power strip seems mostly confusing and inconsistently reported, so I wouldn’t base the decision on that alone.

I absolutely dislike condos . There are no privacy and you pay to have a someone make designations as to what you can do in this space . I lived in one in my 20s and never again .

You know I never really did check if they allow aquariums in my Condo. They do have pet rules about dogs. I am on the first floor though. Ehhh, who cares.

It's probably saying in Virginia it's illegal to use it for more than 1100 watts.

I wasn't allowed to have aquariums in my dorm down at the University of Arizona (don't worry, I didn't graduate from there). I compromised and got land hermit crabs instead.

@That Crusso Kid then you know where I live in the Cape...well more like were my husband lives lol when it's cold in NJ. He wants to sell the house in NJ but I refuse. My kids, brother and mom live in NJ, and I refuse to move to FL. Hubby only wants to live in a condo in FL because it's like a college dorm🙄. His buddies ...old dudes are in walking distance. It's comical...they meet everyday at the pool at 11 AM and depart at 4 PM. They spend all this time in the water talking. There are cameras all over the property.

The condo only allows 40g or less aquariums.
I do recall when you and your husband came down to Cape Coral kind of recently. I think it may have been to get one of your children set up at school.

Only with coffee, bud. Anything goes elsewhere in my life. You don’t reach my age living safely… 🤣
Safety is not my middle name!

Thanks for answering this as I didn't really want to type it all out. Very well explained too!

On a more serious note, I found out my landlord supplied WiFi is 5g only and won’t let my inbird hook up. I’m think of looking for a Bluetooth solution, unless anyone knows of a product that’ll work with the higher bandwidth?

Get a 2G network extender?

Not sure I follow as all WiFi 5 devices will work on WiFi 6 or 7.

Now, if the Inkbird only operates on WiFi 2.4 then you could have a problem. However, there are sometimes work-arounds for these too.

Btw - it is GHz. Not G.

The ink only 2.4 ghz. Makes it useless. Might as just use heaters built in temp controller at that point.
