EGO Nexus Power Station Review | Modular Battery Inverter

The EGO Nexus Power Station is the best battery inverter we’ve reviewed with solid power and excellent capacity

The EGO Nexus Power Station is giving lithium-ion power supplies a kick in the pants with its unorthodox design. I say unorthodox, but outside of the Kohler enCube and Goal Zero products, there aren’t many big names in the battery-powered inverter space taking on 2000-watt gas generator/inverters, so I guess they’re all unorthodox. In any case, this is the best battery inverted we’ve ever tested—and we’ve brought in some of the biggest names in the industry.


  • Capable of powering many 15A tools
  • Flexible lithium-ion power source options – use one to four EGO 56V batteries in any capacity combination
  • Nearly silent, emission-free power
  • 2000-watt continuous power handles up to 3000 surge watts
  • Easily replaceable/upgradable batteries
  • Large, bright LCD screen
  • Simple yet useful app offers controls and more detailed info
  • Handles some 15-amp tools and has higher output than most other battery-powered options
  • Firmware updates offer easy and free upgrades down the road
  • Roll cage offers extra protection


  • Onboard capacity is well under Goal Zero’s max
  • Won’t make it past the startup surge of all 15-amp motors


The EGO Nexus Power Station is the best battery inverter we’ve tested so far. It lets you run tools up to 15-amp handheld worm drive saws. That may get even better with firmware updates. While short of matching the total capacity of the Goal Zero Yeti 3000 on its own, the flexible design makes it easy to carry extra batteries in reserve. Whether you’re looking for no emissions, low noise, or just need to run your power source inside, the EGO Nexus Power Station pushes access to reliable power further than ever before.



This system is a far cry from the EGO Nexus Escape which outputs 150 watts. The EGO Nexus Power Station can output up to 2000 continuous watts with 3000 peak watts out. Those are pure sine surge watts and at 50% over its continuous output rating, it exceeds what a 2000-watt gas generator/inverter can do by a long shot.

The Power Station runs on any combination of EGO 56V batteries. The EGO battery inverter possesses 4 ports, but you don’t have to use all of them. You can use just one if you want. The type of battery (or batteries) determines your maximum output watts.  With a 1P pack (2.0 or 2.5 Ah), it runs at 600 watts. It bumps up to 1200 watts of output with a 2P (5 Ah) battery. To get the 2000-watt maximum, you need to run at least one 3P (7.5 Ah) battery or equivalent in smaller packs.

It’s really about the number of cells. EGO’s 56V battery runs on 14-cell groups. 14 cells on the Power Station gives you 600 watts and 28 cells bump it to 1200 watts. With 42 cells or more, you get the maximum 2000 watts output. It doesn’t matter what combination of batteries you use.

You can also mix batteries without issue. When you use batteries with different capacities or charge states, the EGO Nexus Power Station will draw down the highest one(s) first until they’re all at the same level. Then it pulls equally from all battery packs together.

Real World Testing

So what can you do with 2000 continuous watts and 3000 surge watts? Lots, apparently.

Goal Zero’s Yeti 3000 moved us into the 13-amp range for corded tools. The EGO Nexus Power Station will run 15-amp tools. I started with a standard 15-amp sidewinder circular saw cutting 3/4″ OSB subfloor and then stacked it to make 1.5″ cuts with a 15-amp Skilsaw worm drive saw. Even pushing the worm drive, I didn’t trip the Power Station.

EGO Nexus Power Station

Out of curiosity (and because it was 85º in mid-February), I plugged in our 17,500 CFM drum fan and ran it on high to see if I could still cut with that sidewinder at the same time. It turned out that I could. Of course, you can trip the unit if you push too hard. The fan puts out an additional 900 watts, or 7.3 amps. Running that and pushing the saw harder brings the total draw higher than 2000 continuous watts.

EGO Nexus Power Station

We also tested Skilsaw’s larger worm drive table saw and that seems to be where the limit lies. This battery powered inverter can’t currently handle the startup surge on that tool.

I say “currently” intentionally. One of the beautiful things about this kind of inverter is that the electronics and Bluetooth/WiFi connections permit firmware updates. If EGO finds they can better optimize the output, an update can be made available to download.

So far, the only battery inverter that’s been able to make cuts on that saw is DeWalt’s Portable Power Station. It’s just severely limited in battery capacity compared to EGO.


This seems like a good time to talk about resetting the Power Station. The electronics make this very easy. Just turn the main power switch off and back on, turn your outlets on, and power is restored. Alternatively, hold down the blinking reset button for 3 to 4 seconds, then turn your outlets back on. Either method works fine.


The total capacity of the EGO Power Station is the sum of the batteries you put on it. Stick four 2.5 Ah packs on it and you get 560 watt-hours to work with (140 watt-hours x four batteries). Here’s what some other options look like:

  • 4 x 5.0 Ah batteries: 1120 watt-hours
  • 4 x 7.5 Ah batteries: 1680 watt-hours
  • 2 x 7.5 Ah and 2 x 5.0 Ah: 1400 watt-hours

EGO Nexus Power Station

Kohler’s enCube sits at 1200 watt-hours with its lead-acid battery. Goal Zero has multiple options running from 150 watt-hours up to 3000. EGO stops well short of the 3,000 mark, but it’s easier to get your hands on spare batteries if you need more capacity. And remember that the Power Station can run on just one battery.


It seems curious that the charging unit is external, but that’s intentional. It gives EGO the option of offering an upgraded rapid charger down the road without needing any modifications.

When our 7.5 Ah batteries arrived, they were nearly dead (1 bar each). It took just under 13 hours to complete the charge cycle. Your charge times will vary based on the batteries you use. The onboard charging port pulls 170 watts (EGO’s standard charger is 210 watts and their quick charger is 550 watts). Here are some estimated optimal charging times:

  • 4 x 2.5 Ah: 4 hours, 3 minutes
  • 4 x 5.0 Ah: 8 hours, 7 minutes
  • Four 7.5 Ah: 12 hours, 10 minutes

When you plug the charger in, the LED screen will tell you the estimated charge time once it stabilizes.

If you have more than one battery onboard, the charger automatically switches from one battery to the next. Instead of fully charging before moving on, it switches at a consistent interval. This keeps the group’s charge state close in case you need it before all batteries fully charge.

One important note: You can’t charge and discharge at the same time. If you power anything and plug in the charger, it cuts the power and prioritizes the charge cycle.

Additional Details


Check and see if there’s a firmware update straight away. Some of the earlier units may need it. They’ll still run, but they’ll run better and have the latest firmware after the update.

New vs Old Batteries

Any EGO 56 batteries work in the Power Station, but they may perform differently. The original EGO batteries have a red/yellow/green level indicator that blinks like a Christmas tree when inserted into the Nexus.

The new batteries have a 5-LED ring to give you a better idea of how much charge you have and aren’t as “festive”.

One other thing—the original batteries can put out up to 90 amps (5,040 watts) of power. The newer packs produce up to 130 (7,280 watts)! There’s an 80-amp fuse on the Power Station, so you won’t access all of that potential.

Add a Battery in Use

Did one of your batteries go dead? You can pop a charged one in while the Power Station is running without interrupting your power. It’s kind of like adding gas to a running generator—except this battery powered generator runs on lithium-ion cells.

Roll Cage Design

Dropping a battery inverter off your tailgate probably means the end of it unless you’re using the EGO Nexus power inverter. Its roll cage gives it a fighting chance to survive. EGO intentionally designed it to let the batteries pop off to avoid worse damage.

Environmental Conditions

The EGO Nexus Power Station has an IPX4 rating. It can handle splashing water for 10 minutes, but it’s not designed to leave out in a storm. Since it produces no emissions, there’s no problem bringing it inside the tent or cabin with you. Besides, do you really want a family of bears plugging in and watching TV while they eat all the food from your cooler?

High-Vis LCD Screen

The LCD screen has a black background with easy-to-read white and red graphics—even in bright sunlight. The display is also larger than Kohler and Goal Zero, making it easier for those of us who can’t see like we used to.

Not Crazy Heavy

Even with the batteries onboard, I can carry the Nexus pretty well thanks to the handle design. I don’t really want to lug it a long distance, though. It weighs a little over 29 pounds bare and 54 pounds with four 7.5 Ah batteries. The charger and cords add another 2 pounds.

Get More from the App

The LCD screen gives you valuable feedback, but you can see more details in the app. Here’s what you can do/view:

  • Toggle between Bluetooth and WiFi connection
  • View current watts out per outlet
  • Turn outlets on/off (full bank of USB and individual outlets)
  • View battery charge status on each port as a percentage

Who is This For?

The EGO Nexus Power Station works well as a quiet, emission-free power supply for jobsites, camping/hunting, emergency power, tailgating, and more. The potential use for providing emergency power really sheds some light on the benefits of a device like this. If you’re a homeowner, you can stick your gas generator outside and enjoy most of your comforts after a storm.

But what if you’re in a 5th story apartment?

You can run the Power Station inside without any fear of building carbon monoxide. It’s a great solution for folks that live in the city, especially considering the average power outage is just 3 hours.

That isn’t quite as reassuring in hurricane and earthquake-prone areas where outages often last for days. However, EGO is bringing solar panel compatibility soon. That’s something that will make it a better option for multi-day outages. I’d go with at least 200 watts of panels to get a reasonable charge during the day.

EGO Nexus Power Station


There’s a pretty wide spread of prices depending on what kind of capacity you need. EGO is kitting the Power Sation at The Home Depot with two 7.5 Ah batteries for $1199. If you already have other batteries and can make it a group of 4, you get more capacity. If you don’t, 7.5 Ah batteries run $350 each. The would bring your total cost to $1899 with 20% more capacity than the Yeti 1400.

  • Kohler enCube (1200 Wh): ~$1100
  • EGO Nexus Power Station (840 Wh): $1199
  • Goal Zero Yeti 1400 (1400 Wh): $1799.95
  • EGO Nexus Power Sation (kit + two extra 7.5 Ah packs – 1680 Wh): $1899
  • Goal Zero Yeti 3000 (3000 Wh): $2999.95

Want to match the capacity of the Yeti 3000?

Start with the kit. Four extra 7.5 Ah and two extra 5.0 Ah packs get you 3080 Wh.

Total cost? $3037—about $40 more than the Yeti 3000. And Goal Zero isn’t going to help you maintain your lawn.


The Bottom Line

The EGO Nexus Power Station is the most capable, best battery-powered inverter we’ve tested so far. It lets you run tools like 15-amp handheld worm drive saws. That may get even better with firmware updates. While short of matching the total capacity of the Goal Zero Yeti 3000 on its own, the flexible design makes it easy to carry extra batteries in reserve if needed. Whether you’re looking for no emissions, low noise, or just need to run your power source inside, the EGO Nexus Power Station is pushing your access to reliable power further.

The best place to buy the EGO Nexus Power Station right now is at The Home Depot.

Really wish they’d release or at least announce the solar adapter already…

Would this power station Run an Electric Power Washer or a Vacuum for Detailing Cars?

Art Rubin

thanks for the very useful review. I wondered if you or any of the readers out there would know if the unit that is available today will be able to take the solar charging once that is released (i.e. will solar compatibility just require a firmware update or will only newer version be able to take in the solar charge)?


I build and sell my own. I put everything inside a rolling toolbox (you have to lug this one) and I hang solar panels off the luggage handle to charge while not using. I didn’t see the need for a USB port, but may add to future models. I have a power strip mounted to the outside of the box and a master switch for easy of shutting down the inverter. Bottom Line is I am $1500 for 2000 watt hours and have a way to recharge


Love the ideal of light weight and compact can’t wait to see one or find one to buy and use… I did see that no running times were posted on long it would run on fully charged batteries.
