Whether you’re looking for a backup power source for outages, off-grid electricity for an RV, or simply want to keep your laptop and smartphone charged while working remotely, portable power stations offer an effective solution. These handy devices, which are essentially packs of rechargeable lithium-ion batteries, are quiet, exhaust-free alternatives to noisy gas generators.

Portable power stations come in a broad range of sizes, running the gamut from smaller models capable of charging a phone and powering a laptop for a day of remote working up to high-capacity power stations that can keep your fridge running and lights on during a days long power outage. We’ve tested power stations from some of the top brands to find the best models.

Maximum Output

A portable power station’s maximum output is the total amount of wattage the power station can produce and determines what you can and can’t power with it. Look for a power station that can handle the combined wattage of the electronics you plan to plug into it. If you want to power a toaster that uses 400 watts simultaneously with a blender that uses 600 watts, then you’ll need a power station that has a maximum output of at least 1,000 watts.

For example, we were able to power a refrigerator, air fryer, toaster, and space heater with the Anker F3800 Plus, which puts out a max 6,000 watts, with plenty of power to spare. The Jackery Explorer 300 Plus, meanwhile, produced just enough power to operate a blender with its 300 watt max output.

Many power stations also have surge power that allows them to produce higher wattage for short bursts. This is designed specifically for appliances that draw more watts in the first few seconds that you first start them up, including power tools, blenders, and window air conditioners.

Capacity

A portable power station's capacity, which is listed in watt hours (Wh), determines how much power it can store and, hence, how long it can serve as back-up before requiring a recharge. Power stations with more watt hours can run for longer. Exactly how long depends on the amount of watts the devices connected to the power station draw. You can roughly estimate how long a power station will last by dividing the amount of watts devices are drawing from it by its watt hours.

Keep in mind that the usable watt hours are not the same as the watt hours listed on the power station’s label. You’ll typically get about 85 percent of the listed watt hours due to power lost in connections and from electricity the power station itself uses to power its inverter and display. Given those losses, you can expect to get about 85 percent of a power station’s listed watt hours in usable power. So, a 2,000Wh power station will typically have about 1,700 usable watt hours.

Battery Technology

These days most portable power stations, including all those we recommend here, use LiFePO4 batteries, which are capable of holding far more cycles, which is the number of times a battery goes through a complete discharge and recharge, than older lithium-ion batteries while also being less likely to combust. Their one drawback is that they have a lower energy density, which means it takes more LiFePO4 batteries than lithium-ion batteries to produce the same amount of power. Still, this is the battery type of choice for portable power stations both large and small.

Portability

While all these power stations are portable, some are easier to transport than others. A power station’s portability is directly related to its power capacity and output.

Small power stations with around 300 watt hours of capacity and a max output of 300 watts, such as the Anker Solix C300 DC portable power station, typically weigh under 10 pounds. and are about the size of a lunch box.

Mid-size models like the Bluetti Elite 200 V2 portable power station, which have a max wattage of between 2,000 and 2,600 watts and a 2,000Wh capacity are about the size of the printer in your home office and weigh around 60 pounds, just small and light enough for one person to carry from one room to another.

Large portable models such as the EcoFlow Pro Delta 3, which can sustain a max output of up to 6,000 watts with a 4,000Wh capacity, can weigh up to 135 pounds and are about the size of a suitcase. While these monsters are too large for one person to lift, they do sit on wheels that allow you to move them over flat surfaces, technically making them portable.

Ports

Portable power stations have an array of output ports, including USB-C, USB-A, car accessory, AC, and RV. Consider what types of appliances or electronics you’re planning to charge and the type of connections they use when choosing a portable power station.

Since the wattage of the output can vary, also consider the maximum charging output of each port to avoid disappointing recharge times. For example, a power station with a USB-C port that has a 15-watt max output will take a much longer time to charge a laptop than one with a 140-watt USB-C port.

Controls

Portable power stations have control panels with LED displays and buttons that turn off and on inputs and display usage and remaining power. Most portable power stations are also compatible with Bluetooth and Wi-Fi, allowing you to monitor and control them remotely from a smartphone app.

UPS

Most large power stations, including the EcoFlow DELTA 3 Plus and Anker F3800 Plus, can serve as an UPS (uninterruptible power supply) for your home. To use these power stations as a UPS, plug them into the wall, then plug whatever devices you want backed up into the station’s AC output ports. When the power is on, those devices use energy from the grid. When there is a power outage, the power station instantly switches these devices to battery power. If you live in an area prone to power outages, thus can be useful to prevent data loss from a connected computer, keep medical devices running, or even the pump and filter on a fish tank.

Noise

Portable power stations heat up when operating for extended periods or when they’re providing power for multiple devices. Internal fans will kick on to keep the power station from overheating. While these fans are far quieter than the roar of a gas-powered generator, they do still create some noise. Smaller power stations are about as loud as a small fan, while larger ones produce about the same amount of noise as a refrigerator.

In our most recent testing, we evaluated five power stations of varying size, focusing on each model’s maximum output, capacity, charging time, and portability. To test max output, we connected enough electronics and appliances to each power station to meet or slightly exceed their listed max output to see how well they could operate at maximum load. We then tested capacity, using an electricity usage monitor to record the total watt hours each power station produced while running them under a consistent load from 100 percent to 0.

Once they were drained, we charged each power station from 0 to 100 using their AC adapters, timing how long it took to get to 80 and 100 percent capacity. Finally, we evaluated each power station's portability by attempting to carry it or roll it. Other factors that weighed into our decisions included the number and power output of each power station’s inputs and its charging options.

We previously tested the EcoFlow Delta Pro and Jackery Explorer 1000 v2 and still recommend them among the best—but don’t have the same test results and numbers as the five power stations above.

Our picks for the best portable power stations range from smaller models you can comfortably carry in a backpack for a day of remote work to full-size battery banks that can effectively function as a whole-home backup.

With a max wattage of 6,000 watts, the Anker F3800 Plus had no problem handling the combined load of a miter saw, table saw, blender, and space heater when we put it to the test, demonstrating its tremendous power output.

It has a capacity of 3,840 Wh (we recorded 3,230 actual watt hours), enough to serve as a whole-home backup for the essentials for a day or two. We ran a space heater at a consistent 1,300 watts for about 2.5 hours and a fridge for a full day.

If that capacity isn’t enough, the F3800 Plus is also expandable. You can add another F3800 Plus power station using a Anker Solix Double Power Hub to double the output and capacity and also add expansion battery packs to increase its capacity to a max 53.8 kWh.

Large portable power stations with their 100-plus-pound weight are inherently difficult to move. And while the F3800 is one of the heavier models at 135 plus pounds, its upright suitcase-like design and four sturdy wheels made it easier to wheel around the tester’s garage and living room than other large power stations that only have two wheels and a handle. And with its small footprint, we was able to keep it out of the way in a busy kitchen by tucking it into a corner. (You can also lay it down into a horizontal position, which is useful for RVs)

The Anker F3800 Plus is loaded with six AC ports (most have four), which allowed us to load it up with various appliances and power tools without having to use a power strip. There’s also an RV port for campers, and a 240-volt port for larger appliances such as an oven or dryer.

It took us just under two hours to charge it from 0 to 80 percent power using the included AC power cord and a standard 120-volt outlet. The F3800 Plus also comes equipped with two solar inputs for a max of 165 volts, which equates to a max 3,200 watts of solar panels. This means that, with enough solar panels, you could feasibly recharge this beast with less than two hours of direct sunlight. You can also charge the F3800 at EV charging stations or via a car charger.

The Explorer 300 Plus is light enough for me to carry in a backpack over a short hike through the trails in our tester’s backyard, yet still powerful enough that we were able to use it to make a protein shake in a blender. It’s this balance of power and light weight makes Jackery’s newest version of the Explorer 300 an ideal option for camping trips or off-grid remote working. It pumps out a max 300 watts (we recorded a max sustained wattage of 310 watts), yet weighs just over 8 pounds and is about the size of a lunchbox.

Along with being light, the Power Plus 300 also gives you a bevy of charging options. There are inputs for charging via a power cord, car accessory port, or solar panels. It took about 76 minutes to charge from 0 to 80 percent capacity using the included AC cord.

The Jackery has five power ports, including a DC input, AC three-prong outlet, two USB-C ports, and one USB-A port, which is similar to other portable power stations of this size. While I liked the variety, I had mixed feelings about their max wattage output. The 100-watt max output of one USB-C outlet was ideal for a MacBook Pro, but the second USB-C’s paltry 15 watts was too low to fast charge an iPhone 15.

This new version of the Explorer is an upgrade of its previous iteration, trading a lithium-ion battery for a longer lasting LiFePO4 battery. The main difference here is its lifespan. Whereas the older version of the Explorer 300 was rated for 500 cycles before dropping below 80 percent capacity, the Explorer 300 Plus gets a whopping 3,000 life cycles.

If you don’t mind the lower wattage of some of its output, the Jackery Explorer 300 Plus offers great power output and capacity in a lightweight package.

Bluetti manages to pack a lot of power into the Elite 200’s surprisingly compact size and manageable weight. It boasts a max output of 2,600 watts with 3,900 watt startup power and a 2,073.6-Wh capacity.

We hooked up a miter saw, blender, and space heater, all three of which it powered simultaneously, easily handling the spike to 4,000 watts to start up the saw, above its listed 3,900 rated lift power, before maintaining an even flow of around 2,500 watts.

The Elite 200 also impressed with the quality of its battery. We recorded an impressive 92 percent of its listed 2,073.6-Wh capacity, well over the 85 percent average for most portable power stations. The Elite 200 also boasted a quick recharge time for its capacity, going from 0 to 80 percent in 81 minutes and to full in just 107 minutes.

And since it uses a LiFePO4 battery, you can discharge and recharge it a whopping 6,000 cycles before it drops below 80 percent capacity.

The Elite 200 gives you plenty of output and input options for its size. Four AC outlets allow you to load up multiple appliances. There are also four USB ports for charging smaller devices, a car accessory outlet, and a DC output. Along with its power cord, there’s also a port for charging from a car accessory port or with up to 1,000 watts of solar panels.

The Bluetti Elite 200 is also surprisingly light at a manageable 53 pounds. This made lifting and carrying the Elite 200 short distances around our workshop an easier task. With a great power-to-weight ratio, the latest version of the Bluetti Elite 200 is a great portable power station for powering a camper or providing backup power for the essentials.

With its tremendous capacity, the EcoFlow Delta Pro 3 is truly a portable power station designed to function as a whole-home backup. Our test rig came with one expansion battery, giving this power station a whopping 8,096-Wh of capacity.

Whatsmore, the Delta Pro 3 was also the most efficient power station we tested, putting out 97 percent of its listed power capacity, which means most of that 8,096-Wh is usable energy. We was able to run a space heater pulling a consistent 1300 watts for nearly 6 hours.

Similar to other large portable power stations, the Pro Delta 3 is modular, which means you can add up to two batteries to increase its storage capacity by adding battery packs and a second power station to reach a max 48k Wh.

The Delta Pro 3 produces a max output of 4,000 watts, or up to 6,000 through its X-Boost technology, which automatically turns on when wattage demand exceeds 4,000 watts. This is especially useful for devices that require more power when you first turn them on or when under a heavy load, such as window air conditioning units and power tools. We pushed it well above 5,000 watts with no noticeable lags by simultaneously operating an air fryer, toaster, and a space heater while making intermittent cuts with a miter saw.

The Delta Pro 3’s four AC plugs do limit the number of appliances you can plug into it. We were forced to add a power strip to add enough appliances to push its output limits. However, the Delta Pro 3 does offer two different types of 220-volt outlets and a 30-amp RV outlet, along with four USB outlets for smaller devices. In addition to its power cable, you can also charge this EcoFlow with a car charger or via two solar ports for a total of 2,600 watts.

Referring to these larger power stations as “portable” is being generous, and the EcoFlow Delta Pro 3 is no exception at more than 113 pounds. The Delta Pro 3’s two wheels and extendable handle allowed us to wheel it around our living room and kitchen like a piece of luggage, but it was difficult to move over a threshold between the garage and kitchen. The expansion pack sits on top of the power station, which saves space, but pushes the whole kit to a total weight approaching 200 pounds.

We took the Anker Solix C300 with us for a day of remote work at a local coffee shop, easily stowing it in a backpack. Its tall and narrow shape and 6.3-pound weight makes it the smallest and lightest portable power station we tested.

Despite its compact size, its max 300-watt output and 288-Wh capacity are comparable to larger power stations that weigh several pounds more. It kept a laptop, portable screen, and smartphone charged for the entire day with plenty of power to spare.

The CS 300 is limited to DC outputs, which include four USB-C, two USB-A inputs, and a DC output, but it makes up for it with the high output of those ports. Two of its USB-C ports put out max output of 140 watts each, which allowed us to charge a MacBook Pro from 0 to 80 percent in just 75 minutes even while continuing to use it with multiple browser windows open.

While the CS 300 lacks a power cable, you can use both 140-watt ports as inputs to fast charge the C300 from 0 to 80 percent, a process that took just one hour, though we needed two charging cables and power blocks to do so.

Add in a lamp that extends from the top—allowing it to function as a lantern with three brightness settings and 28-volt input for charging via a solar panel or car accessory port—and the CS 300 is the ideal small power station for camping or remote work.

EcoFlow’s Delta Pro is a massive power station that rivals the output of gas-powered generators. The brand claims it will power nearly any appliance, and after testing, we’re inclined to agree. With an output of 3,600 watts, it can handle multiple appliances, and you can bump the output to 4,500 watts with its built in X-Boost technology if you need more power.

In testing, running with a continuous 470-watt load, as indicated on the Delta Pro’s display, it provided power for 6 hours and 57 minutes. Of course, in a home back-up during a power outage situation, we would run only what was needed to conserve power. To that end, we used it to power a full-size, 25-cubic-foot refrigerator—which it did for a remarkable 51 hours and 24 minutes.

Recharging the power station from empty using a standard 120-volt home outlet, it recharged to full capacity in 2 hours and 36 minutes. You can also charge the system, with the included adapter, at EV charging stations, with solar panels (sold separately), a car charger, or combinations of these to speed things up.

The Delta Pro’s display screen provides all the important information you need to manage you power consumption. We frequently checked the screen during testing to see the unit’s charge level, current load, and estimated run time at the current discharge rate.

All of this information is also accessible through EcoFlow’s app, which was the most intuitive and easy-to-use of those tested. We connected the app both locally using Bluetooth and via Wi-Fi remotely to monitor the power station from anywhere. We could also toggle outlets on and off remotely, which is helpful if you’re trying to manage power station output to extend the battery life.

We’ve also tested the brand's Whole-Home Backup Kit, which includes two of the power stations and a dual voltage hub used to connect to your home service panel, via a transfer switch. We used this set-up to power critical circuits in a Northeast Pennsylvania home in late winter.

The Delta Pro Whole Home Kit ran just over 24 hours, powering kitchen outlets, a full-size refrigerator, a chest freezer, a cable modem and wireless network, and a hot water boiler. The two Delta Pro power stations had been previously stored with 100 percent charge for 8 months, and maintained their full charges.

Testing was performed under normal usage conditions—run time could easily be extended by employing standard power-conservation strategies like lowering the thermostat, powering the fridge and freezer for four hours on and four hours off, and only opening the them when absolutely necessary. EcoFlow’s Delta Pro Whole Home Kit is a legitimate home back-up system that can operate inside your home, with none of the risks or potential hassles of running a generator.

The Jackery Explorer 1000 V2 is a new and improved version of the previous iteration of this model. Jackery increased the storage capacity by 70 Wh, and bumped the output by 50 percent, to 1,500W. This means you can power devices with higher loads, like an electric grill or large microwave. Jackery managed this while maintaining the Explorer 1000’s compact size and weight, which means it’s still easily portable for activities like camping.

The Explorer 1000 features three standard 120v AC outlets, two USB C ports (30 and 100W), one USB A port (18W), and one 12V DC outlet. Paired with Jackery’s app, you can monitor it locally via Bluetooth, or from anywhere when it's connected via Wi-Fi. In the app you can check charge levels and estimated run time, as well as toggle any of the outputs on or off.

Plugged into the wall, the Explorer 1000 recharges in under two hours. Using an optional 200W solar panel will take longer, at over seven hours—but that time can be reduced using multiple panels. It can also be charged from your vehicle, taking up to 12 hours.

Performance wise, the 1000 V2 did well powering a 25-cubic-foot refrigerator for 18 hours, 22 minutes, which is better performance than we've gotten from other tested 1000W models. Under a constant load of 475 watts—that’s a little less than a small coffee maker—it ran for 1 hour and 57 minutes.

This power station offers a lot of bang for the buck. Sure, it isn't going to power your house through a days-long outage, but it offers a lot of nice features for the price, making it one of the better values out there, especially if you can pick it up on sale.

How long do portable power stations last?

A portable power station’s lifespan depends on the type of battery. Most newer portable power stations, including all the models we review here, use LiFePO4 battery technology, which lasts far longer than older lithium-ion technology. How much? LiFePo4 power stations will last for more than 3,000 charge cycles, or about 10 years, far longer than the 500 or so charge cycles and three to five years of a power station with a lithium-ion battery.

How long does it take to recharge a portable power station with solar panels?

That depends on the capacity of your portable power station, the wattage of your solar panels, and the weather. For example, a 1,000Wh power station that’s receiving a consistent stream of 200 watts of power from a solar panel would take about 5 hours to recharge (1,000/200=5).

Are portable power stations weather resistant?

Some have weather ratings. The Bluetti Elite 200, for example, has an IP65 rating, which means it can withstand water sprays from all angles. However, other portable power stations do not have a weather rating, so it’s important to check if you plan on using your power station outdoors.
