EcoFlow Delta Pro vs Delta Max – What to Buy?
We have three incredible power stations from EcoFlow that you can consider buying for your home or outdoor needs. The Delta Pro is the highest-end model and is perfect for a home backup system. Its two lower-end models, the Delta Maxes, have modular features and are perfect for use in RVs, campervans, and other outdoor activities.
The great thing is that all the machines have expandable battery packs, allowing you to take their storage capacities to higher levels. This means you can power more of your appliances and other gadgets.
The Delta Pro is especially exciting, as you can pair two of them with a Smart Home Panel to achieve double inverter power of 7200 watts at 240V. Plus, it comes with an LFP battery, which is a bit heavier but offers ultra-safety and longer lifespans. Meanwhile, the Delta Max variants come with NCM lithium battery packs that make them much more lightweight and easier to take on trips.
For instance, the Delta Pro weighs 99 lbs, while each Delta Max weighs only 48 lbs. However, remember that each model comes with different storage capacities and is meant for different purposes. The Delta Pro is perfect for home backup, while the Delta Max variants are better suited for outdoor use. With the right solar panels or other power options, you can get unlimited portable power!
