If you search the Costco website it shows up and than says product not found.

The newer model is in my Austin, TX Costco for $99, its same as old model but with a USBC port. Seems cheaper than other local retailers by at least $50, but seems regular price at Costco. I picked one up cause winter is coming and I can't wait for the coupon book sales LOL.

Definitely a consideration if you're connecting this to a computer. Be nice to your power supplies and they'll be nice to you!

Although tricky, the more adventurous should also consider buying used/refurb true sine wave units as the worst case is often that you'll need to swap in new batteries (so price those out as well).

Good luck!
Jon

Yeah, but those sales are how often? ON a quick SD search, I'm not seeing any 1500VA True sine for $130 in any recent deals. 1350VA @ 810W for $135 back in March 23, 2020 is the closest I can find.

This price is what I'd expect from Costco for simulated sine. If you don't need pure sine, this deal is fine. I've personally used Cyber Power w/simulated sine for 2 UPS for well over 4 years and haven't had an issue with any of the PC's I've had connected to it. I'd argue simulated sine will still beat out not having a UPS. If you can't for over the premium for pure sine, simulated sine is a good stopgap. Just imagine installing or updating OS and the power goes out. Best case scenario without a UPS, you're doing a clean OS install.

pretty sure this is normal price. i believe last year's BF they had the 1500VA for $99 which was sold out before I got to make it to store. hopefully they come back with it this year.

Good deal.

With the supply chain and inflation issues, getting anything at prior low prices is good.

In the past we could find 1500VA pure sine wave models for $130 on Black Friday.

I expect this Black Friday to be very poor compared to the years prior to the Pandemic.

Costco in general have increased prices ..

many others are also increasing prices.

Oil is up, Shipping rates have skyrocketed ..

Every CyberPower UPS I have owned seems to develop the same annoying behavior. When the power glitches ever so briefly, the UPS tend to simply shut off, requiring it to be manually turned on to restore power to all connected devices. I am referring to the daily Florida sub-second power glitch that does not impact most other gadgets throughout the home. While it might relate to aging batteries, the front panel does not show any obvious problems as it displays them at 'full' capacity. Maybe it is a 'protection' feature but I would prefer for the power be restored like a normal power strip would (hmm... "Alexa, turn my CyberPower UPS back on"). Anyway, my fourth CyberPower began doing that a couple of weeks back so I picked up an APC from Sam's this time around (to my chagrin, at regular price because I just could not wait Frown).

I've had that same problem twice, all on the 550 va models. One was only 3 months old. It's a valid failure covered under warranty but you need to mail the machine back to them.

Very annoyed, they claim its a battery failure but expensive to mail back these heavy devices. Don't understand why they won't turn back on when power returns. Was gone for a month and couldn't access anything because router connected to the UPS.

I hear this a lot, but I think it's misleading. I have extensively used simulated sine wave for power supplies and have never run into any issues. This is consistent with everyone else's experience you'll find on the internet as well.

I've run a home network with 3 servers, 2 switches, a firewall, modem, several iot devices, desktop with two monitors, and a mesh system off of three of these for the last year.
No issues with it being simulated sine despite it keeping me working through several brown/blackouts.

Modern electronics are generally unaffected.

Agreed. This is like many issues here on Slickdeals where one user mentions a feature is a little better than a different feature then that difference gets repeated and exaggerated until is does not resemble reality in the slightest. For example, there is endless comments about how knives with really good steel are actually trash because it isn't M390 and is just D2. This discussion here is similarly without merit. If PC power supplies routinely handle raw outlet power, they can handle a simulated sine wave.

If you are really concerned GET A GOOD POWER SUPPLY. That is far more important than sine vs non-sine.

Also, don't trust people who say "1500VA true sine wave can be found for around $130 on sale" but cannot support this with an actual link. If that was once 4 years ago, it is just impractical to wait, especially since prices are going up on everything and will likely never go down again.

FYI If you log into the Costco app, you can find the 99$ model.
