Portable Power Packs - LifePo4 Battery Boxes -- How I done It --

loving the EF R 2 MAX. . .

same top quality as all the EcoFlow units.

same APP aswell.

still running it through its paces. . . so far its run everything.

As for the 12v Pump . . . . . . . . .
 
as for the pumps. . . .


i have this OutdoorMaster 20PSI SUP pump that i use for our air tents.

says a 12A fuse, . . . . . and 110w

so far its been fine with all the 12v power packs. . . . at least up to 8PSI anyway.



the only time it cut out a battery pack was when trying to add air to a tent that was already at around 5psi. . .

as this is a twin pump, high volume to 1psi, then swapps to a High Pressure pump from 1pSI.


when connecting the pump to the tent it read 5psi . . but wouldnt start (tripped out the power pack)

the easy fix was to disconnect the pump from the tent and start it running . . . then plug in the air pipe to the tent. . . this was enough to keep the pump running up to at least 8psi without cutting out.

we also have two of these from before. . .

12v and up to 12.5PSI,

this one is up to 10A 12v.

these work on all the 10A battery packs aswell. . . .

so if you want more than the 10A output for any big pumps. . .

assuming max power draw at say 15psi. . .

then a @Dellmassive battery box is the way to go.

i have twin 50A Anderson outputs that will run any pump.

with a Anderson to High Power 12v socket adapter . . .

thanks for all the info you’ve put into this thread so useful

Quick question, for someone with limited electrical understanding- how can I work out the most efficient way to run my Alpicool cf45 from my EcoFlow delta mini - assuming there is a different draw of power from the the ac / dc inputs - what would the difference in run times etc?
 
Glad the threads help.....


In theory the cf45 should use the same wattage from either 12v or 240v.

So you would expect the run time to be the same.(ish).

Ish = You would expect slight efficientcy losses in the 12v to 240v conversion..(so slightly less run time)

So the best way to be sure is test it.

****

Fully charge battery pack to 100%

Fill the fridge with cans or bottles of water.

Start with everything at room temperature, set fridge to 1 Deg C.

Connect fridge to 240v.

Run fridge for 24 to 48 hours.

End test by switching off and noting remainder of battery state of charge.

*"**

Allow fridge to return to room temp,

Then repeat test using 12v.

****

Compare the remaining state of charge.

....


If you do the test, post your results here.

Dell's way would be the 'proper' way to do it

Could you not do a more basic approach which is plug it both and see what the screen on the box or the app tells you? It should give you a watts readout

funily enough . . . we done just that before.

Fyi.. run time. Dometic CFX3-35. On AC, 44kwh/A (year) 44kwh / 365days is 120wh per day. So according to the quoted numbers the 256wh box should run that fridge for 2days.. 2*120 - 240wh. ... I'm not sure about the quoted 12v DC operation.... ++++ Energy consumption (DC@5/25°C) 0.47...

240v - 50w / 6w - expect 20.2 hours.

53w / 0w


++++++++++++++++++



its also important to note that the Dometic fridges have a separate 240vac input, and a separate 12vdc input.


some of the Chinese units have a 12vdc input - but then just supply a dc power brick that plugs into the mains. . . so an external power supply possibly even 14.5v ( which is good).



++++++++++++++++++


this is important as in my testing the units were happier with the 240v mains as running off the 12vdc side the voltage was already say 12.3v . . . then with volt drop over the cable the fridge may struggle with lower voltage, so draws more current. the fridge may see 11v at the compressor . . . . in which case its better to run from a small pure sine wave inverter.

+++++++++++++++++++

thats how i run my fridges . .


battery box with 12v out.

into one of these small inverters. . .

That’s great, what a reply thanks.

Will have a read through that tonight and give it go next few days and report back.
 
Dell, couple of questions
- Ecoflow is pure sine wave for 240v too isn't it? Would it make a difference plugging into that rather than using a separate device? My fridge needs a 240v power brick, so it's easier to use the 12v output from the EF unit, just saves a device. But you have an EF so wondering why you're saying you use an inverter with it?
- Why do you reckon your fridge takes 6w on 240v when not running, but 0w on 12v? Do you think that's the fridge's internal inverter drawing power?
 
Yes the EF is pure sine.

Traditionally I always used SLA battery's for camping.... So have been using inverters for years.

The portable power packs are relatively new.

And yes as you say you can use the 240v or 12v from the power packs.

So the best test is to try it out and see what happens....

In some.of the pics above you will see me using the 240v from the power packs into a extension lead.... Then onto the fridges and lighting etc.
 
Sorry for a very basic question, but I’m new to power banks - and this thread is amazing! What sort of Wh should I be considering to run a Dometic CFX30, recharge two phones and iPads and maybe an occasional LED light?

without solar, and just using the battery pack,

prob 500-1200wh for a weekend.

depending on numerous parameters, temp, how often fridge opened or reloaded, what tablet, how may phone recharges etc etc etc .


+++++


if you added 200w solar in summer then you might get away with the 256 - 600wh range.


+++++

ie - a 200w solar suitcase like this one. (then panel VOC spec needs to be below the power pack solar input spec)






1689152641083.png

Specifications​

  • Max Power at STC: 200W
  • Open-Circuit Voltage: 24.3V
  • Short Circuit Current: 10.42A
  • Optimum Operating Voltage: 20.4V
  • Optimum Operating Current: 9.82A
  • Dimension: 1062x530x70 mm
  • Weight: 15.6 kg


and say this 512wh power pack:

1689152798086.png



++++++++++++++++++++++



that should see you good.


so charge at home via 240v,

and top up with solar,

or just take to campsite office and ask to plug it in for 30mins if no solar.


you can also connect to van 12v socket for a 8A 100w slow charge while driving (engine must be running or you will flatten the starter battery)
