MAINS BLACKOUT - can the EcoFlow River 2 save my PC work? 

No problem Alan - thanks for the great idea. Please subscribe to the channel!

It's much more than 3000. After 3000 you have only lost a fifth of the capacity

I've not heard of that functionality requirement. That must be for a specific computer UPS I guess. A bit out of the design scope I would say

@@CampingSecretsUK every modern computer has a UPS function under power on a desktop PC you will see a little battery icon in the tray when one is connected just like a laptop with an internal battery.

I think that would work yes. I've used a power station to charge another power station. The only problem is that you're doubling up on efficiency losses. Ultimately though, you've got more battery capacity, so you've got more storage.

​@@CampingSecretsUK I am hoping the R2 Max will have enough power to run my Gas central heating unit, that draws 40watts (when it’s running) and my Fridge at 120watts (when it’s running) So if my calculations are right, I should get about 2.7 ‘continuous hours’ of runtime. So more than enough for any three hour scheduled power outage. One disappointment is that the New River 2 series does not have an expandable “Extra Battery” pack however, I do have a load of 5Ah Ryobi 18v one+ batteries and an aftermarket power cap that has a XT60 plug already fitted to it. Witch I am hoping will charge the R2 by about 80Wh (giving us an extra half an hour of continuous runtime) per battery Guess I'll find out, when it all arrives :)

@@FiddlingwithmyWhistle great stuff. Good luck!

@@CampingSecretsUK and yes. I saw you used a power station to charge another power station when you use the USB-C cable... how does it know witch way you want to charge ? You charge the R2 from the Delta ". but what if you wanted to use the R2 to top up the D2 ?

That's a good question. I don't think the Delta 2 has USB-c charging capability. If it did then I have no clue what would happen. Safer to charge using the AC in and out in that case

This is true, and I'm not able to test that. I think you could be right and there is no actual switch from mains to battery. Battery all the time, with the mains keeping the battery topped up seems more likely. I'd be interested in what this does to the battery lifetime but have no info.

@@CampingSecretsUK Good point! EF defines lifetime of its batteries by the number of charging cycles (e.g. 3000). Since the usage as UPS does not result in complete zero-to-full charging cycles, this must not affect battery lifetime ... theoretically.

That's quite an interesting idea, I'll have a go. What kind of laptop do you have, and should it be fully charged first or not?

@@CampingSecretsUK I am running a basic desktop pc sir. Ryzen 5 5600g CPU no external GPU and 16gb of ram and 1 monitor. Power wattage pull based from my wattage meter is around 65 to 80 watts for the PC during full load (work stuff, chrome and MS office) and 15 watts for the monitor. I guess I could pretty much get the jist of how long mine can stay running if you could put in the wattage pull of your setup sir. ;)

Yes the Ecoflow fast charging is excellent

Yeah if you want the fastest switch time then you buy a dedicated switch. For matters of life and death that's a no brainer

I had to Google that - Emergency Power Supply - yes you're right, because the battery will obviously only last a short time. However, as long as the power outage is shorter than the stored capacity time, it's effectively a UPS

The pc was drawing about 100W, and so it would keep it going for about two hours. Enough time hopefully for the power to come back

​​@@CampingSecretsUKA computer is 100 watts?

@@Peace-tk3gr yup

Why? What's the difference? I'm dealing with daily blackouts over here and this feature for the PC would be very welcome.

@@Pandamasque I live in Kyiv so I know what I am talking about we have electricity about 6hours a day every day sometimes even less than that, 6-7hours no electricity 2 hours electricity then again 6-7h no electricity and I already tried most powerstations, inverters, UPS and other solutions to help myself to overcome this struggling 😉 and I have the same power station as well, including few more from Bluetti, if EcoFlow has X-boost on believe me it can sometimes turn off your pc when grid will get off and will not do the same when you just unplug cord because when you just unplug cord your voltage doesn't do voltage drops, its a common EcoFlow problem, they have AVR with 30ms ups mode its kind of slow when voltage drops or gets high. Lab Mode, X-Boost means no UPS mode because UPS mode is very sensitive to voltage. When I first purchased River 2 I did the same tests as you, unplugged the cord and wow UPS was on and what was my surprise when electricians turned off grid suddenly and my pc turned off)))

@@deraid712 Same situation. Pechersk, Kyiv. I've had 2h of power today so far. I had to turn down a job opportunity, because I don't even own a laptop. I'm on my phone right now with a wifi router powered off a 20000mAh powerbank. Your explanation gave me an idea though. You can plug the River2 into a wall via a power strip with an on/off switch. 5 minutes before the scheduled outage you manually cut the power via that switch (like unplugging, but more convenient). And the PC will keep running. Flip the switch back on after the outage happens so River2 is ready to start charging as soon as the power comes back. It's not ideal, but it's cheaper than buying a true UPS to put between River2 and the wall socket.

This doesn't help if it's an unscheduled outage!

Interesting comment sir - I will test it again. I send my best wishes to you and your country. Keep up the good fight
