Needed an extra battery for my Ecoflow Pro and this was cheaper than even used or refurbished units.
Thanks for the heads up!

Looks like they charge tax for TX now. My previous DELTA Pro was from them, and I didn't pay tax.

Using the code POWER10 instead of those two saves you another $4.

you mean without the inverter? because this does have a lifepo4 battery inside it.

btw, this is very old tech, dating back to 2021. this model is almost 4 years old. the fact that this made the frontpage at $1587.49 is laughable and shows a lack of credibility on the part of slickdealers.

the delta pro 3 would be front page worthy at $1587.49, but not this old outdated tech. this should be more like $1200 max.

thumbs down!

How much power does your refrigerator use?

waiting for Delta Pro 3 deal.

My home has a generator circuit with NEMA L14-30 120/240v plug. DP3 has it.

I don't know. It is old class refrigerator, I guess average one. My question is can these power banks be replacement to normal electricity in a modest apartment?

You will need to know the usage to calculate whether these types of battery can sustain your house.

A quick Google shows that an average refrigerator uses about 60 watts an hour. This DELTA Pro is capable of 3600 watts an hour. That means you can power your fridge for 3600 / 60 = 60 hours.

If you have more devices, add their wattage up to know the hours.

Watts an hour? Nonsense. That's like saying horsepower an hour.
The term is watt-hours. One Wh is a power consumption of one watt for one hour. Sixty watt-hours would be used when a 60-watt bulb was operated for an hour.
Never-the-less, math is correct. However, a more logical means would have been to use the refrigerator's daily power consumption (1200 Wh) and divide that number into 3600 Wh capacity to arrive at 2.5 days.

The Delta Pro is ~90% efficient meaning it can put out ~3240w. My 90s refrigerator uses 75w/h which is ~43 hours of runtime.

Sure, its a 4 year old design but it is also priced accordingly. It is still a monster power supply. I'd much rather have a Pro 3 for the same price too but seeing as you can't get it I am not sure why you would mention it.


The price on these are continuing to drop. If you aren't in immediate need there will be better deals in the future. For comparison purposes I bought mine a few months ago from Aputure for $1300 shipped which was better than I could find refurbished units being sold for with coupon deals. If it weren't for that deal I probably would have gone with the Pecron E3600LFP.

Can you carry these easily to charging stations? I am guessing these are not replacements for home electricity. I am paying triple on recurrent account charges than actual electricity used.

I guess it depends on your definition of easily, but these weigh 100 pounds. They also need an adapter to charge from a car charging station. Also if recurring base charges are most of your cost, this won't help you. You can't just turn your power off and the utility stops billing you. It's probably impossible to get disconnected since you live in an apartment.
