I was able to test my new setup a while. To challenge it even with 2 fridges (what isnt my current setup in europe) - I had the time for, because I had an heavy addicent (not with a car).
I am needing power for
two 12v compressor fridges (Freezer / Fridge), my Notebook, Camera, Smartphone, Tablet, Drone, some LED Lights at night.
I did it 9 years ago as a DYI Project for beeing able to staying self sufficent some days offgrid with my travelling car.
At 2011 $1500 not a cheapie, very capable, 95 AH AGM Battery, B2B Booster, Inverter, Solarcharger, Batterymonitor:
Writeup classic powersetup (35kg AGM)
Did serve my well during my transafrica and further international journeys.
Then I did try the same at 2021, with LiFePO4 and new components. I wasnt able to beat this ecoflow device in weight, size or price. Here is my updated Setup from 2021:
At 2021 710$ LiFePO4/Lithium 576Wh Battery solution with 8.5kg:
Writeup mobile offgrid solar solution with LiFePO4 It is still strong enough, and I did save a lot of weight and get new space inside of my car.
- It allows to charge with 500W(!!) at campsites, 200W with Solar, 120W during driving with 12v. Just sun let
my consuments running extended (weeks) during summer with one 100W EFTE Solar Panel (!!).
- You can charge most devices directly with 12v, even a Mac Book pro - because there is a 100W USB-C Socket.
- 1200W/600W Power Inverter 110v/220v. As you can see, he can run (with undervolting) many devices like a water kettle witch use power way about specs.
- You have an App to use as remote control and have a good Battery Computer.,
- it is small, lightweigt with 8.5kg.
You cant get it smaller and more lightweigt even with using double of the cash as a DYI Project, without dropping some requirements.
It is perfect for my Power consuments named above.
I`m currently on a detailed writeup about a DYI Project for a bigger LiFePO4 project, still struggeling to get a USB-C 100W Port for 12v as example.
Those Battery boxes bring a great value! And Ecoflow has the best specs, if you look at the details. And the buildquality is great, I have add a dismantle disassembly and teardown video in my link above.
You can still find LiFePO4 based new/used devices in the FB Group if you ask -and are willing to pay shipping/import. Otherwise you have to optain with lithium specs ;-)
