In the Costco app, in the warehouse tab in the bottom navigation bar, you can search for inventory and price of a particular item. You can compare prices and availability if there are multiple stores near you.

I've been using one of these for my modem, router, and nas as a ups. Extremely quiet. When I test run it down under load, the fans will be at max, I can barely hear it. I like the app for EcoFlow way better than the BLUETTI app as well.It's not much different size wise, from old style ups's I've used in the past. I got sick of those old ones running for all of 5-15 minutes…. Then having to replace a lead acid battery every 3-5 years… ugh. This one has a constant 53w load on it for my internet stuff/NAS and I added an expansion battery from a previous sale I got through the app, to it, a couple months back to double the runtime. I honestly have no complaints other than I have it set to only charge to 80% but it will go between 80 and 90%, albeit very slowly over the course of a week or so. Not sure what that's all about but whatever. It's the only nitpick I can find. These barriers last so many cycles anyways I'm not concerned too much.I run it down to zero every few months then back to full as part of my hurricane preparedness checks and so far it's great and it's worth the money imho.If you want a good ups that is quiet with a bunch of good app features, this is the one. Btw, I don't use this for my computer because it's a beast that goes over 700w in gaming 😬*I didn't realize this was a 'wireless' version, my bad. I have the standard non wireless one but still similar/same product basically and I'm happy with it.

My Costco store was pretty useless. First guy I asked said "the Costco app is usually wrong in inventory we don't carry it. 2nd guy I by the checkout lane in the red vest straight up said "This is a road show item and we don't have it". I asked them to check inventory and he said it says "we have 2 but we don't carry it or it will be on this isle"I had him check the other stores and one store had 11 and another had 6. I literally saw these in the store a month ago but waited for a sale. Usually the Costco app will say low inventory but it definitely failed me tonight since I went at closing hours ☹️But I am a big fan of the 5000mah silver battery packs. Bought 3 as gifts and was super impressed. Super strong magnet and has a built in kick stand and slim enough.

Just picked one up the last one for $100.00 on clearance at Fountain Valley, CA. ($160 - 60). Pretty slick.

For UPS usage, be aware that it shuts off power on firmware updates ..kinda bad design decision 😕
