EcoFlow Delta 2 + Extra Battery Charging Speed and Fan Noise [Quick Look link in description]

[namenotfound]

It does charge faster than any other power station I have ever seen.

[brianpollard]

It only sounds like that if you are fast charging. But if it is doing a normal charge rate it won't sound as loud.

[Miki-mwby]

Even if the fan was loud. You won't actually charge the Delta 2 inside the bedroom.

I think it just sounds like any other power station except that it can charge quite fast.

[SAMMIEJONESJUNIOR]

That is not loud or a aggravating noise I have 1 snd I don't really notice it at all.

[alleng]

Can you charge the extra battery while the eco flow 2 is plugged into the 110 outlet

[CB-kddn]

It does show that the fan is actually working and cooling down the hardworking Delta 2.

When connected to an empty or incompletely charged extra battery the power station will shift its own capacity into the battery. In the end you have two half-full or equally charged devices but none at 100%. In order to use the complete original load you now have to carry two heavy units with you instead of only one. In other words: while connected you cannot get a completely charged main unit unless the extra battery is fully charged too. What is the deeper meaning behind this?

Video Review: Visual good, commentary was a little weak.

[theonlyEYEBROWKING]

Looks like the main unit is 100% charged but the EB is not. Can you charge the EB separately being that the main unit is fully charged?

[ES-mqox]

Sounds very similar to a vaccum cleaner or a hair dryer set on high. And with that high pitched shrill sound, I would think it's a bit too much for almost anyone to remain nearby for an entire 50 to 80 minute full recharge session. No late night/early morning stealth charging at the camp ground bathrooms, that's for sure. It would wake half the campground up.

Try changing the charging rate to 900, that keeps the fan noise to a minimum

[raedalshaye]

Thank you for sharing this . Question for anyone who knows. If you turn off AC charging, the main Delta 2 can function as a 900-watt outlet. Will the extra battery charge the main unit at the same rate (900 watts)?

[taraskuz]

You can lower watts so the cooler will make less noise and better battery lifecycle

[pollyaloy]

All ecoflow need to do is stop putting cheap fans in the units .

Bonjour le câble est-il fourni avec la batterie supplémentaire merci beaucoup

[tfergo]

can you use these to charge leisure batterys in a camper van and also connect to solar pannels on your van ?or do you have to use eco flow panels ? any help appreciated

[HansKeesom]

When running on battery I am fine with the fan-noise, when running on AC(in) it shows this does not have a transfer switch but does AC->DC->AC. Which not only is noisy but also inefficient. That is why I installed a real transfer switch at home which uses the Delta 2 as generator in case the grid goes down.

However, this does not take away the fact that the Delta 2 is using like 16 watt no matter what it is doing, a bit wasteful
