(Last Updated On: April 1, 2022)

If you’re in the market for a portable power station, you’re looking at many options. The power station market has expanded over recent years due to technological advances and because of the need of having portable power when people are traveling. Depending on your needs, you could go for a simple power station with a lower price, but that comes with its limits, such as low power capacity and insufficient output power.

The best choice is to go for a mid-range power station with just enough capabilities for your needs, and that’s what we think the EcoFlow Delta Mini power station does. This EcoFlow is a brand known for creating top-tier power sources such as solar panels, power banks, and power stations. The EcoFlow Delta Mini sits at a great spot, and we think it can fit into what most people are looking for, so let’s take a closer look to see why that is.


Power Capacity:

One of the integral parts of a power station is its high power capacity, as the output has to keep up with the capacity to ensure that you can use the unit for a long time. This EcoFlow Delta Mini has an 882Wh power capacity, tons of power. Smartphones can easily charge more than 50 times; laptops and tablets with similar battery sizes can charge more than ten times.

When it comes to powering appliances, it’s then about runtime, and even then, the Delta Mini does a great job with powering low, mid, and higher wattage appliances. Power capacity duration does fall drastically when it comes to power higher wattage appliances. For example, you can power a 500W blender and that can last for about 1.5 hours, a 65W projector can last up to 9 hours, a 40W CPAP machine can last up to 13 hours, and a 200W Playstation 5 can get you 3 hours of gaming.

So mid-tier appliances are what this power station was made for, as it offers an ample amount of output power and can keep these lower wattage appliances powered for hours. However, higher wattage appliances will heavily drain into the Delta Mini’s power capacity leaving the unit depleted rather quickly; with that said, we must say that running out of power unexpectedly isn’t a problem because you get a clear display that shows just how much time is remaining until the Delta Mini is out of power.

The max output of the Delta Mini portable power station is 1400W, so it’s important to stay below that threshold. If you’re looking to power a 1000W Microwave, the power station will last you about 36-40 minutes. Electric frying for when you want to hook on a road trip or a camping trip that is 1200W will get you about 30 minutes of constant usage. Once again, the runtime of the Delta Mini when running lower or mid-tier appliances is very useful, and it’s still amazing to run higher wattage appliances. Still, those can deplete the 882Wh power capacity much faster.

Charging Ports

The way you can use this Delta Mini is impressive. On one side of the Delta Mini, you’ll find the charging ports, including three USB-A ports and one USB-C Power Delivery port. The USB-C Power Delivery port has a 100W output, which enables you to charge most USB-C charged devices, including laptops, tablets, and smartphones. In our test, we charged a Lenovo IdeaPad Flex 5 at its max charging speed via the USB-C PD port, and the same can be done for most other USB-C laptops such as Macbooks, Dell, and Samsung laptops.

Of the three USB-A ports, two have a standard 12W output, and one of the USB-A ports features Quick Charge for fast charging Quick Charge compatible Android smartphones. We quickly charged a Samsung Galaxy Note 9 via the Quick Charge USB-A port, while we standard charged an LG G7 and a Galaxy A51 from the two standard USB-A ports.

On the opposite side is where you’ll find the rest of the output selection of the Delta Mini, and it includes an AC outlets section with five AC outlets and another section with two DC5521 ports and a car port.

AC Outlets

Of the fives outlets, you have two that are three-prong outlets. As we mentioned before in the power capacity section, the higher you go with the wattage of the appliances you’re powering, the faster you deplete the capacity. That said, disregarding the power capacity, the 1400W max output of the EcoFlow Delta Mini power station is truly flexible. With so much power, you can plug in many devices to charge and be powered simultaneously.

We had three phones, one laptop, an electric bug zapper, and a heater connected to the Delta Mini; the Lasko heater was the highest wattage appliance connected to the Delta Mini, which was pulling about 800W. An essential factor to know is that we are were running the heater at Low and not high because the high setting on the heater requires 1500W of power. Using the high setting eventually makes the Delta Mini automatically turn off.

X-Boost Feature

The EcoFlow Delta Mini power station and many other EcoFlow power stations have a hidden trick, though, which would be their X-Boost feature. The X-Boost features enable the Delta Mini to output a continuous 1800W. This lets you power appliances that go above the max 1400w output of the Delta Mini, but the only way that X-Boost can be activated is via the EcoFlow app. With the boosted 1800W, you’ll have less time to use the power station as the capacity is used a lot faster.

Our recommendation is to use the X-Boost of the Delta Mini sparingly because it goes further than what the power station is capable of and can affect battery longevity in the long run.

There is a 2100W Surge output that will make the Power Station run for a short duration.

Overall, the number of AC outlets is plentiful, and with 1400W output, you can power microwaves, TVs, or power tools for when you’re working outside and don’t want to run an extension cord from inside.

Car Port and DC Ports

The section with two DC5521 ports and the car outlet may be the least used on this power station. Fortunately, we did find a usage for the car outlet. We used a portable tire pump with the car outlet, and it worked just fine. The usefulness of the DC5521 ports depends on if you have any compatible devices to use with them, such as certain appliances that use the ports or a laptop that charges via a DC port.

Input Charging:

There are three options for charging the Delta Mini, and you get three cables included in the box to use at least two of them readily. An AC charging cable, a car charging cable, and a solar charging cable are in the box. Unless you already have a solar charger with solar connective ports, then solar recharging is not the immediately usable type of recharging that you can use. Still, it’s helpful if you’re in the wild.

Regular recharging speed

Instead, the best way to recharge the Delta mini is via AC charging because you can recharge the unit at 200W at regular speed. However, you can use X-Boost recharging with the flick of a switch and upgrade to a 900W recharge rate. Yes, by just using a switch, you can recharge this power station faster, and it’s one of the coolest features we’ve ever seen.

X-Boost Recharging speed

Recharging a power station should be fast, and the X-Boost feature accomplishes that.

Car charging is also available but charges the Delta Mini at the slowest speed of the three methods.


Size and Weight:

Being a portable power station, the “mini” part of the EcoFlow lineup makes sense as the Delta Mini is a good size for all your traveling or stationary needs. We will say, though, that the 24-pound weight of the mini is quite heavy and not something that you’re going to hold for a long time.

The Delta Mini has a length of 14.9 inches, a width of 7.2 inches, and a depth of 9.4 inches. So not too big, and you’ll be able to fit it into your car or store it in your home with no issues.

Functional Components:

Using this EcoFlow Delta Mini is simple enough, but there are things to know.

On the side with the charging ports is where you’ll find an LED screen that shows the remaining power capacity, how much usage time you have left of the power station, the output wattage, the input wattage, and what parts of the power station are being used. The LED display also shows if the Wifi functionality is on to connect to the EcoFlow app, and it shows the speed of the fans inside the Delta Mini.

The screen is a significant part of the power station to tell you what’s happening, and we think it’s straightforward to understand see what’s going on.

On the opposite side of the charging ports is where you find the AC ports, car ports, and DC ports; it’s also on this side is where you’ll find the recharging ports that can be found under a covering. The AC port and the car port section each have power buttons to turn each section.

Functionality when it comes to the structure of the Delta Mini is the large handles to the sides of the unit, and they are necessary to use when picking up the power station.


Structure and Material:

The build quality of Delta Mini is superb. The entire structure is made of plastic, but we don’t think that making it out of Aluminum Alloy would be much different for the safety of the unit. Even with its plastic build, the unit’s structure is solid, and you won’t have to worry about it getting damaged by bumps or light hits if you’re traveling with it in your car.

It’s not exactly a rugged build, though, you should be careful about the Delta Mini falling from a high height as it’s not shockproof, and neither is it waterproof, so keep it away from water.


When it comes to portable power stations knowing the safety features you get is essential for such a high wattage device. The Delta Mini has a total of 5 internal fans that change speed depending on how much wattage you’re using from the power station. The more wattage you’re using, the faster the fans spin; the less wattage, then they spin slower.

If you go over the 1400W output without X-Boost activated, the unit will automatically turn off.


As we mentioned at the beginning of this review, the Delta Mini is one of the best portable power stations to start with. Most beginner power stations have too low wattages, even though they may have a good enough power capacity. The Delta Mini has a very high 1400W output that can be boosted to 1800W if needed and an 882Wh power capacity to back its output power.

The five AC outlets, four charging ports, a car port, and two DC ports are handy ways to use the output power because it opens a broader range of appliances that you can power via the Delta Mini. Yes, we realize that the price of the Delta Mini isn’t exactly low, but for what you’re getting, it’s worth it over being limited by other lower-tier power stations that may have a lower price.



The 882Wh power capacity is enough to charge large and small devices to full power multiple times and power higher wattage appliances for a couple of hours.


The Delta Mini is heavy at 24 pounds, but the size is great for traveling with. Using the Delta Mini is simple enough; with just the press of the main power button to power on the unit, you can then use the charging ports; the AC port and the car port sections each have their power buttons.


The Delta Mini is made well, but you still have to be careful about dropping it, especially exposing it to water, as the unit is not waterproof. Four internal fans keep the unit cool and have varying speeds depending on the power station’s output.


The Delta Mini has a significant amount of power capacity and output power that can power a wide range of appliances that lower-cost power stations can’t.
