The best portable power stations for a sump pump
Only protecting the basement? Most homeowners are better served by a battery backup sump pump. It is a second pump with its own battery that turns on by itself; our pick pumps nonstop for 3.8 to 4.8 hours per charge. Buy a power station when you also need the fridge, Wi-Fi or a CPAP running, or your pit has no room for a second pump.
Buy the EcoFlow DELTA 2 Max ($1,049 at Amazon). It clears this plan's hardest motor start on the maker's own peak rating, it sells on Amazon, and it takes expansion batteries if one day turns out not to be enough.
The Jackery Explorer 2000 v2 holds much the same battery for less money, but its peak rating starts the pump only in the best case, which is a gamble on the one thing you are buying it to do. Buy the EcoFlow DELTA 2 Max ($1,049 at Amazon). Less money, thinner margin: the Jackery Explorer 2000 v2 ($999).
A sump pump is a motor that starts hard and then runs in bursts: the starting surge decides which station can start it at all, and the weather decides how much energy it drinks. Sized on the harder end of every range.

Who this is for
You have a pump in a pit that fills when it rains hard, and you would rather not learn what happens when the same storm takes the power out. You want something that runs indoors, starts the pump on its own with nobody standing there, and keeps the router and a few lights going while it does.
How much battery you need
Two numbers come out of this plan and only one of them decides the pick. Keeping everything running takes 730 to 1,620 watts, which is the easy part. Starting the pump takes 2,030 to 4,620 watts for a split second, and a station whose peak rating falls short of that does not run the pump weakly, it does not start it at all.
Adjust this plan to your house. Change the hours or the loads and the picks are re-scored here, with the same planner and the same maker figures.
Where the energy goes, load by load
| Load | Hours | Running watts | share of time running | Energy | Share of worst case |
|---|---|---|---|---|---|
| Sump pump | 24 | 700–1,500 | 5–35% | 840–12,600 Wh | 90% |
| Wi-Fi router and modem | 24 | 15–40 | 100% | 360–960 Wh | 7% |
| A few LED lights | 8 | 15–80 | 25–75% | 30–480 Wh | 3% |
Energy = running watts × share of time running × hours, at each end of the range. The right-hand end of every row is what the plan is sized on.
A sump pump, Wi-Fi and a few LED lights for 24 hours, run against all 82 units we track: 37 clear at least the best case, 41 do not, and 4 could not be judged (a missing maker figure or an unclear recall status). Every figure is from the maker’s own page or manual; nothing here was tested by us. The method.

The EcoFlow DELTA 2 Max clears the hardest motor start on EcoFlow's own peak rating, which is the number this plan cannot compromise on, and it is still a one-person carry rather than a fixture. It covers the quiet end of a 24-hour outage and not the storm end, which is true of everything portable.
How we picked it: the cheapest unit that covers a typical day of this plan (4,000 Wh). The same-size EcoFlow DELTA 3 Max (2048Wh) is $150 cheaper but takes no extra battery, and one charge does not cover this plan.
On a typical day this plan needs about 4,000 Wh, more than one charge, so plan a recharge. A hard-working sump pump may need up to about 14,000 Wh.

The Jackery Explorer 2000 v2 holds much the same battery as our pick for less money and is the lightest of the three, but its peak rating starts this pump only in the best case. That is worth saying without decoration: if your pump sits at the hard end of the range, Jackery's own peak figure does not cover the moment it starts.

What you give up: Margin, everywhere. It may not start a hard-starting pump, there is no expansion port, so the ceiling is fixed the day you buy it, and the solar input is the lowest here, which makes a multi-day refill slow.

Day two and three
Three days (72 hours) of the same loads needs 3,690 to 42,120 watt-hours. None of the three picks covers even the bottom of that on a single charge, and neither does anything else we track, so past the first day the question stops being which box and becomes how you put energy back into it.
Hooking it up safely
The plug-in path is the plan on this page. The station sits indoors, the fridge, router and lamps plug into its outlets, and nothing touches the house wiring.
Wired loads are a different job. A well pump, a furnace or a whole circuit needs a transfer switch or a power inlet installed by a licensed electrician (which switch fits which station or generator). Never feed a station or a generator into a wall outlet: it backfeeds the line and can kill the crew restoring your power. The safety rules and pass-through and output quality.
Buying it right
A search for these models returns bundles, sibling models and the same unit under two prices. We link only a listing whose own title states the unit on its own with its exact battery and output. Match the model number on the label to this page. How we check a listing.

What this page can’t promise
This page sizes a battery against a pump. It does not know how fast water comes into your pit, which is the number that decides everything here, and it cannot promise you a dry basement. It is also worth saying plainly that this is the one appliance you back up while standing in the place that floods: keep the station up off the floor and well away from the pit, and do not wade anywhere to reach it.
Nothing here was tested by us. The figures are the makers' own, read off their pages and manuals and cited under each pick, and where a marketing page and a printed manual disagree we say so rather than take the better number. What owners report comes from public threads and hands-on review sites and is labelled as such.

Questions people ask
Can a portable power station run a sump pump?
If its peak output clears your pump's starting surge, yes. This plan needs 2,030 to 4,620 watts for a split second, and a station rated below that will not run the pump weakly, it will fail to start the motor. Energy is the second question and a separate one: how long it lasts depends entirely on how much water is coming into the pit.
How long will a power station keep my sump pump going?
That depends on the water rather than the battery. Across 24 hours this plan needs anywhere from 1,230 to 14,040 watt-hours. In a dry spell the pump barely runs and any of these picks carries the day comfortably; in the storm that took the power out it can run a third of the time or more, and no portable battery we track covers that on one charge. Size for the storm.
Does the pump have to stay plugged into the station the whole time?
In practice, yes. A sump pump runs off a float switch with nobody watching, so it has to already be plugged into the station when the grid drops. All three picks pass grid power through to whatever is connected while they charge themselves, then take the load over in a few hundredths of a second when the supply fails, which is quicker than a motor can notice. Set it up that way in good weather.
