Best Portable Power Stations for Off-Grid and Outages

A portable power station is a lithium battery, an inverter and a solar charge controller in one box you can carry. It runs 120 V appliances, charges from the wall, your car or solar panels, and makes no fumes, so it can sit inside your house, cabin, van or RV.

This guide covers the carry-it-yourself class: about 1 to 2 kWh, under 45 lb, a few hundred dollars to about $1,500. If you want to back up a whole house with 240 V circuits, see our best solar generators for home backup instead. Prices and specs below come from each maker's own US store and spec pages, checked on November 4, 2026.

How to choose in four questions

1. How many watt-hours do you need?

Capacity, in watt-hours (Wh), is how long it lasts. Virginia Cooperative Extension's appliance energy guide gives the formula: watts × hours used per day ÷ 1,000 = kWh per day. Do that for each device you want to run and add them up.

Then leave a margin. The inverter loses some energy turning battery power into 120 V AC, so for our own planning we count on about 80% of the label capacity. By that rule a 1,024 Wh unit gives roughly 820 Wh at the outlet, enough to run a 100 W load for about 8 hours. That's our rule of thumb, not a maker's figure, and real results vary with the load.

Our off-grid solar calculator does this math and adds how much solar you'd need to refill it in your state.

2. How many watts at once?

Output, in watts, is how much it can run at the same time. Add the running watts of everything that might be on together. Motors and compressors (fridges, pumps, small RV air conditioners) pull extra for a moment when they start, which is what the surge or peak rating covers.

EcoFlow's X-Boost lets some high-wattage devices, like a kettle or a hair dryer, run above the rated output by lowering the voltage. It suits heating loads, not motors, so size for the rated number.

3. How will you recharge it?

• Wall: all five picks refill from a household outlet in roughly an hour or two.
• Solar: check the max solar watts and the voltage window. Every pick here accepts 60 V or less on its solar port, so you'll wire panels in parallel or small series strings, not a long rooftop string.
• Car or RV alternator: a 12 V cigarette-lighter socket only puts in about 100 to 120 W, so it takes many hours. A dedicated alternator charger is far faster (see the RV section).

4. Can you carry it?

Weight matters more than you'd think. A 25 lb unit goes anywhere. A 45 lb unit is a two-handed lift you won't want to carry far down a trail.

Five portable power stations compared

All five use LiFePO4 (LFP) batteries and put out 120 V only. Price per Wh is the listed price divided by capacity, our math. EcoFlow's DELTA 3 Max weight is converted from its 20.3 kg spec, and the DELTA 3 Classic from 12.1 kg. Sale prices change often, so check the page before you buy.

The picks, one by one

Best budget pick: EcoFlow DELTA 3 Classic

At $479, the DELTA 3 Classic was the cheapest 1 kWh LFP unit we found on these makers' stores. It stores 1,024 Wh and puts out 1,800 W of pure sine wave power, with X-Boost up to 2,600 W for heating loads and a 3,600 W surge. EcoFlow lists 0 to 80% from the wall in 45 minutes, a 10 ms auto-switch for keeping a router or NAS running when the grid drops, and up to 500 W of solar input.

It's the one to buy for a fridge, lights, phones and internet through a short outage, or a weekend at the campsite. EcoFlow's warranty is 3 years standard plus 2 more when you register in its app.

Most capacity under $650: Jackery Explorer 1000 Plus

The Explorer 1000 Plus holds 1,264 Wh, about 24% more than the 1 kWh units, for $619. It has three 120 V outlets rated at 2,000 W combined (4,000 W surge), two 100 W USB-C ports and a 12 V car port. Solar input is the strongest in the 1 kWh class: two 12 to 60 V ports, up to 800 W combined. Jackery lists a 1.7-hour charge on its AC adapter and a 5-year warranty on purchases from jackery.com.

Two things to know. Jackery rates the cells at 4,000 cycles to 70% capacity, where Anker quotes 80% after 4,000 cycles. And while the page still mentions expanding to 5 kWh with battery packs, it also says the Battery Pack 1000 Plus has been discontinued, so treat this as a fixed-size unit. At 32 lb it's also the heaviest of the 1 kWh picks.

Lightest 1 kWh pick: Anker SOLIX C1000 Gen 2

The C1000 Gen 2 is the one to carry. It stores 1,024 Wh, weighs 24.9 lb, and puts out 2,000 W (3,000 W peak) across 10 ports, including two 140 W USB-C ports. Anker lists a full wall recharge in 49 minutes at 1,600 W (you turn that mode on in the Anker app), 600 W of solar input that refills it in about 1.8 hours, under 10 ms UPS switchover for a CPAP or laptop, and 4,000 cycles to at least 80% capacity.

It does not take expansion batteries; Anker says it left that out to save size and weight. At $699.99 it costs more per Wh than the others, so you're paying for the low weight and fast charging. Anker's SOLIX store said new orders ship from November 21 when we checked.

Best value at 2 kWh: EcoFlow DELTA 3 Max

The DELTA 3 Max gives you 2,048 Wh for $879, the lowest price per watt-hour on this list. It puts out 2,400 W through four 20 A outlets (X-Boost to 3,400 W, 4,800 W surge), charges 0 to 80% from the wall or a generator in 68 minutes at 1,800 W, and has a sub-10 ms UPS and a 126 W car output. EcoFlow lists it at 25 dB or less at 600 W, which is quiet enough for a bedroom.

The catch is solar: it takes 500 W max, the same as the 1 kWh Classic, so refilling 2 kWh from panels alone takes a full sunny day. For RVs, EcoFlow sells it bundled with a 500 W alternator charger for $1,039. At 44.8 lb it's the heaviest pick here.

Best for RVs and vans: Anker SOLIX C2000 Gen 2

The C2000 Gen 2 is the strongest all-rounder for life on the road. It stores 2,048 Wh, puts out 2,400 W (4,000 W peak), and has a TT-30 outlet, the common 30-amp RV plug, so you can plug the RV's shore-power cord straight in. Anker sells an 800 W alternator charger for it and lists a full charge from the vehicle in about 3 hours, versus 23 hours from a 100 W car socket.

Solar input is 800 W on an 11 to 60 V port, with a full solar charge in about 3 hours at that input. Anker's user guide notes panels must be wired in parallel so the input stays at or under 60 V. Add the wall and you get 100% in 58 minutes. It expands to about 4 kWh with one BP2000 expansion battery, idles at 9 W, and is rated for 4,000 cycles to 80%. At 41.7 lb it's lighter than the DELTA 3 Max, but at $1,499 it costs much more per Wh. Anker's SOLIX store said orders ship from November 21 when we checked.

Solar generator for an RV: what to look for

A "solar generator for RV" is just a portable power station paired with panels. What makes one good in an RV:

• A TT-30 outlet. Most 30-amp RVs use this plug for shore power. With one, the station feeds the RV's own outlets and lights through its existing wiring. Without one, you run extension cords to each device. On our list only the C2000 Gen 2 has it built in. A 2,400 W unit still can't run everything a 30-amp hookup can at once, so turn off big loads like the water heater element.
• Alternator charging. Driving days are your best charging time. A dedicated alternator charger (Anker's 800 W, EcoFlow's 500 W) refills a 2 kWh unit in hours, not days.
• Enough output for the air conditioner. Many RV rooftop units draw more on startup than they do running. Check your AC's startup and running watts against the surge and rated output before you count on it. Anker says the C2000 Gen 2's 4,000 W peak handles most RV ACs; a soft-start kit on the AC helps any unit.
• Low-voltage solar wiring. All five picks top out at 60 V or less on their solar port, which suits the 100 to 200 W panels that fit on an RV roof, wired in parallel.

Which one should you buy?

• Cheapest reliable backup for the fridge, router and phones: EcoFlow DELTA 3 Classic.
• The most battery under $650, with strong solar input: Jackery Explorer 1000 Plus.
• Camping, tailgating, carrying it around: Anker SOLIX C1000 Gen 2.
• The most kWh per dollar for outages or a cabin: EcoFlow DELTA 3 Max.
• RV or van life: Anker SOLIX C2000 Gen 2 with the alternator charger.

Power station or gas generator?

A gas generator runs as long as you have fuel, but it must stay outdoors. The CPSC says portable generators kill an average of about 100 people a year in the US through carbon monoxide poisoning, and tells owners to run them at least 20 feet from the house, never in a garage, porch or carport (CPSC).

A power station is silent and safe indoors, but it only lasts as long as its battery and your sun. Many people keep both: the station for indoor, quiet power, and the generator outside to recharge it in a long, cloudy outage. All five picks list generator charging.

Before you buy

• Add up your watt-hours per day and leave about a 20% margin.
• Check the rated output against everything that might run at once, and the surge against anything with a motor.
• Match your panels to the solar port's voltage window. These all top out at 60 V or less.
• For RVs, look for a TT-30 outlet and an alternator charger option.
• Confirm the ship date. Two of these were back-ordered when we checked.
