Customer Reviews for EcoFlow - DELTA 2 MAX 2048Wh Portable Power Station (2048 Wh Capacity) - Black

I bought this one after watching review videos of different solar generators and comparing specifications. This unit was by far the best option with its lithium iron phosphate battery. I'm a beginner so I've been testing different items around my house to get comfortable with it. I'm planning to take it camping and use the solar panels. Really happy with my purchase.

I purchased this unit to back up a 13 CI Freezer as we get plenty of power outages. Thus far it works well and I may soon connected it to two larger solar panels and keep these for camping.

I've had my delta 2 max now for 3 weeks and so far I'm loving it. It's a little more heavier than the delta 2 is at around 50 pounds vs 28 for the delta 2 but not to heavy for me to carry it around without a problem. I've used it to power various appliances around my house such as a microwave oven, a convection oven, hotplate, hairdryer, space heater and a room size air conditioner and it's handled everything like a champ! The fans are alot quieter than the delta 2 fans also. The fast charging is nice at around 10% it took a little over a hour to charge to 100%. I love the eccoflow app too! It puts everything you need to know about the unit and what it's powering at your fingertips. Overall it is a great unit with lots of awesome features and works really well for what I use it for. I am well pleased with my purchase and would recommend this product to others who are looking for a portable powerstation.

Time to Ditch Gas and Go Solar with the Delta 2 Max!
Let’s do a quick rundown of the new kid on the block and compare it with its little brother, the Delta 2.
The Delta 2 Max is definitely much beefier than the Delta 2. The D2Max sits at 19.6 × 9.5 × 12 inches and weighs approximately 50 lbs. The Delta 2 on the other hand is 15.7 × 8.3 × 11.1 inches and weighs in at 27 lbs. Reading the dimensions may not seem like much of a difference but trust me, it is!
The D2Max sports a whopping 2,048Wh batt capacity! That is DOUBLE the capacity of its little brother, the Delta 2 at 1,024Wh. Of course, we are talking nothing but LFP with an estimated 3,000 cycles to 80% of capacity.
The D2Max also sports an add-on option where you can triple the capacity from 2kWh to 6kWh by adding two Smart Extra Batteries. Kick things off with a blistering 2048Wh base and move up to 4096Wh with a single extra battery. From there, max out at 6144Wh with a second extra battery! Major capacity upgrade!
One immediate noticeable difference (besides size), are the AC outlets. While both have six outlets, all of the D2Max's outlets are grounded outlets. With the Delta 2, only two are grounded. The D2Max provides up to 2,400W total (4,800W surge) AC while the Delta 2 sits at only 1,800W (2,700W surge). EcoFlow's proprietary X-Boost on the D2Max is 3,400W vs the Delta 2 at 2,200W.
USB ports remain the same between the two models, x2 USB-A and x2 USB-A Fast Charging. There are also x2 USB-C (100W) ports for a total of six USB ports. DC/Car Outlet and x2 DC5521 (barrel) outputs also remain the same.
On the input side, the D2 Max sports dual solar inputs (500W each/1,000W total) and a mind blowing 1,800W AC input. This is a game changer with a lightning fast estimated 43-minute charge time to 80% when combining both AC (1,800W) and a min of 600W solar input! Super-fast!
Going to save this for last... Charging at the Max X-Stream setting of 1,800W or any of the variable settings is WHISPER QUIET! This is going to blow you away! I cannot believe how quiet this thing is! The Delta 2 sounds like a jet ready for take-off. Ecoflow must have an Area 51 scientist on the design team. the D2Max is Aurora Stealth quiet! Either that or it was built by Ninjas... ;)
If you are looking for a home backup solution, be the envy of all the other overlanders in your weekend run to the mountains or just light up and power the playa at the next Burn, the Delta 2 Max is the power station you have been looking for!
Way to go EcoFlow, you knocked this one out of the park!
