Both of these designs are intended to provide tons of power that will enhance the options you have whether off the grid or simply prepping for the end of the world as we know it.

Power Output Possibilities

Both designs are intended to give you enough power to run most of your essential appliances like a refrigerator, lights, and other items. In addition to powering these high-usage devices, these systems are also expandable so that you can build a system that

The Bluetti AC300 starts as a 3,000 watt power generator and can be expanded by adding battery packs. It’ll accept up to four of the B300 battery packs rated at 3,072 watts each. With the total of possible power, you’ll have 14,576 watts of available juice to power just about anything, even smaller central AC units.

The Ecoflow Delta Pro also starts out with a base 3,600 watts of continuous power. It can also be expanded to take advantage of the expandable battery packs that will increase output to 25,000 watts. This is enough power for you to run just about any possible device or accessory you can imagine.

Winner: Ecoflow Delta Pro

Recharge Rates

Smaller devices can be expected to recharge quickly, but when you are dealing with this much power, you are going to need to plan on having some time. You can enhance the speed at which these devices will recharge by using a combination of AC power and solar panels, sold separately.

The Bluetti AC300 will accept up to 5,300 watts of input power but you’ll need to use an optional AC wall charger and count on the full amount of solar input, which is rated at up to 2,400 watts. Using everything it can take, the Bluettie AC300 takes less than two hours to reach a n 80-percent charge.

The Ecoflow Delta Pro will also charge fastest when you include the highest level of input possible. It provides you with the ability to add 6,500 watts of total input, giving you a recharge of 100-percent in only 1.7 hours.

The thing that sets the Ecoflow Delta Pro apart from the Bluettie AC300 -and literally every other rechargeable power station on the market- is the fact you can charge it at EV stations. Only this design can do that, giving you a new type of charging that you won’t find anywhere else.

Winner: Ecoflow Delta Pro

Output Ports

The number of devices you can plug in at once is more important than the amount of power available sometimes, particularly when you are primarily charging smartphones, laptops, drones, and other small devices that are commonly useful off the grid.

The Bluetti AC300 offers six 120v AC ports to power appliances. You’ll also find a total of five USB ports including a USB-C 100w port and four USB-A ports. On the 12V side of things, Bluetti adds a 12v and 24v port. On top of the unit, there are dual wireless charging pads to handle your compatible devices needs.

The Ecoflow Delta Pro provides four 120v AC ports. USB ports outperform and outnumber the Bluetti to make up for the two-fewer AC ports, though. You’ll find dual USB-C 100w ports along with two USB-A QC 3.0 ports and two standard USB-A ports. That gives you the power you need for the most useful devices you have. It includes two types of 12v plugs and an Anderson Plug for powering a trailer.

How We Picked

The Ecoflow Delta Pro stands out for a couple of reasons. The most relevant and immediate reason is the ability to expand the power and take advantage of massive amounts of solar and AC power input. This makes the system more convenient regardless of the manner in which it is used. While the Bluetti AC 300 will provide high levels of power when properly configured, the Ecoflow Delta Pro is designed to power your entire house with ease, though upgrading the package to the full wattage is prohibitively expensive.

The Ecoflow Delta Pro is a fully-contained battery backup system that provides more than 3000 watts of power in it’s base configuration and can be expanded to include more than 28000 watts of power. That is enough to easily power an entire household for several days. The device works the company’s battery expanding devices to offer huge amounts of power. Our detailed review of the Ecoflow Delta Pro.


  • More available power than most people will need when fully expanded
  • Easy and simple process for connecting to the home power grid


  • Large and bulky design is difficult to store
  • Add on battery packs are equally large, making an expanded system not portable
