The 4 Best Portable Laptop Chargers of 2023

We’ll be updating this guide soon with testing notes on the Mophie Powerstation Pro AC (our new top pick) and the ChargeTech Premium 27K AC (our new budget pick).

A portable laptop charger is the ideal companion if you want to charge your laptop while traveling or working remotely, in an emergency, or anytime a wall outlet is out of reach. And it's not just for laptops: With its built-in AC outlet, a laptop charger can power other small devices, as well, from vibrators and video projectors to breast pumps and baby monitors. We spent 25 hours researching and 79 hours testing 11 models, and we’re confident that the Anker Powerhouse 100 is the best option. It can keep up with MacBook Pros and other powerful laptops, it's compact and lightweight, and it's one of the few models that come with a wall charger to recharge the unit itself.

This compact, lightweight portable charger has an AC outlet, a USB-C PD port, and two USB-A ports, and it can charge even the most power-hungry laptops while they’re in use. Unlike many competitors, it also comes with a 45 W wall charger.

The Anker Powerhouse 100 performed well in our testing, offering more than 100 W of power output and enough capacity to bring a dead MacBook Air battery up to 90% charged—even during heavy use with the screen brightness turned up. It has a variety of output ports, including a USB-C Power Delivery (PD) port, two USB-A ports, and an AC outlet. The unit comes with a 45 W wall charger and a USB-C cable that you can use to recharge it at top speed, as well as a USB-A cable and a protective cloth carrying case. It's small, ruggedly built, and easily packable, weighing just 1.9 pounds. It's intuitively designed, too, though we could do without the built-in flashlight and wrist strap. It's backed by Anker's standard 18-month warranty, which is one of the longest we’ve seen in this product category.

This model has plenty of ports, impressive capacity, and the power to charge most laptops. It's slim, sleek, and easy to use, and it comes with a wall charger. But it's heavier than the rest of our picks and not as ruggedly built.

*At the time of publishing, the price was $150.

The ChargeTech Portable Power Outlet 27K 4.0 has the same port options as the Anker, higher capacity (it was able to charge our test laptop 1.2 times), and a lower price at this writing. This charger is sleek and compact, making it easy to slip into a backpack or briefcase, and it's just as simple to use as our top pick. But it's not as ruggedly built as the Anker—its metal exterior shows scratches and dings more easily, it doesn't have a protective rubber flap over the AC outlet, and it doesn't come with a carrying case—and at 2.4 pounds, it's a little heavier. As with our top pick, you don't have to supply your own wall charger to juice up the ChargeTech since it comes with a USB-C charging cable and a 30 W wall charger. It's backed by a one-year warranty, which is shorter than Anker's coverage, but that should still give you plenty of time to make sure it's not defective.

Rated capacity: 27,000 mAh (97.2 Wh)Max output: 133 WWeight: 2.4 poundsDimensions: 8.0 by 5.4 by 1.2 inches

This compact, lightweight charger supports wireless charging and has an OLED screen that displays battery life and other metrics. It's not quite as powerful as our other picks, and it doesn't come with a wall charger, but it recharges with any compatible DC or USB-C charger.

*At the time of publishing, the price was $200.

The Omnicharge Omni 20+ is the most lightweight (1.4 pounds) and compact of our picks. This easy-to-use charger looks sleeker than most models, seems durable, and has rounded corners that make it comfortable to handle. If you have a phone or other device that can charge wirelessly—such as a newer iPhone, Google Pixel, or Samsung Galaxy—this is the only one of our picks that has wireless charging capabilities. It's also one of the few models we’ve seen with dual input options (you can recharge it with DC or USB-C PD), as well as a screen showing you helpful information such as input/output wattage, charge level, and operating temperature. If you want those extra features and maximum portability, this is your best option, but there are some notable drawbacks. Namely, the Omnicharge has the lowest output (98 W) and capacity (it charged our MacBook Air only to about 80%) of any of our picks, and it's the most expensive at this writing. And although it comes with USB-A and USB-C cables, the package has neither a case nor a wall charger. Like the ChargeTech, this model is backed by a one-year warranty.

Rated capacity: 20,400 mAh (73.4 Wh)Max output: 98 WWeight: 1.4 poundsDimensions: 5.0 by 4.8 by 1.1 inches

This unit cranks out 149 W—the most power of any of our picks—and its battery capacity is as high as that of any charger we’ve tested. It's heavier than most, weighing over 2 pounds, but it performs as well as or better than pricier models.

The RAVPower 30000mAh AC Power Bank (RP-PB055) may seem expensive for a budget pick, but at this writing we haven't found anything under $100 that we feel comfortable recommending. It's not our top pick because it doesn't come with a wall charger, its rubberized finish collects fingerprints, it's relatively heavy at 2.2 pounds, and it's bulkier than the rest of our picks (especially in its protective hard-shell case), but it excels in almost every other way. It's more powerful than our other picks, capable of pumping out a whopping 149 W to laptops and other power-hungry devices. It charged our test laptop 1.2 times (tying with the ChargeTech for the highest capacity), and like our top pick it has a USB-C PD port, two USB-A ports, and an AC outlet. In addition to the hard-shell case, it comes with a soft mesh pouch and a USB-C charging cable, and its 18-month warranty matches the coverage period on our top pick from Anker. This model is your best bet if you don't mind some added bulk in exchange for having the most power possible.

Rated capacity: 30,000 mAh (108 Wh)Max output: 149 WWeight: 2.2 poundsDimensions: 7.0 by 5.4 by 1.8 inches

This compact, lightweight portable charger has an AC outlet, a USB-C PD port, and two USB-A ports, and it can charge even the most power-hungry laptops while they’re in use. Unlike many competitors, it also comes with a 45 W wall charger.

I’ve been a science journalist for more than seven years, covering a wide variety of topics from particle physics to satellite remote sensing. Since joining Wirecutter in 2017, I’ve reported on solar battery chargers, USB-C cables and adapters, rechargeable AA and AAA batteries, and more. I spent 25 hours researching and 79 hours testing portable laptop chargers for this guide alone.

For a previous version of this guide, I consulted with Lee Johnson, an electrical engineer with more than 15 years of experience designing and testing electronics.

Portable laptop chargers aren't just for laptops. Since they’re power banks with AC outlets, they can provide on-the-go power to virtually any device that draws up to about 60 watts—such as our favorite room fan, floor lamp, or ice cream maker. But since most people who buy these chargers are mainly looking to charge their laptops, we wrote this guide with them in mind. (If you need only USB-C and USB-A ports, our favorite USB power banks are powerful enough to charge a 16-inch MacBook Pro, a Dell XPS 13, or other laptops that charge via USB-C.)

If you work remotely, you may not have consistent access to a wall outlet. Competition for outlets can be stiff at coffee shops, libraries, and coworking spaces. And if you have a long commute, travel frequently, or regularly attend off-site meetings and conferences, an alternative source of power like one of our picks can relieve charge anxiety. This is especially true if your laptop is near the end of its lifespan or if you run a lot of apps and programs at once.

Even someone who is rarely away from their desk might want a portable laptop charger in case of a blackout or other emergency. Ready.gov recommends keeping "an emergency charging option for your phone and other mobile devices." You could always use one of our favorite pocket-sized or high-capacity power banks for this purpose, but a portable laptop charger gives you more types of output ports and, in most cases, more power.

If you have a long commute, travel frequently, or regularly attend off-site meetings and conferences, an alternative source of power can relieve charge anxiety.

We have a separate guide to larger portable power stations, which weigh as much as 50 pounds and can output hundreds of watts—the type of thing you’re likely to want for off-grid living, car camping, or fieldwork.

To find the most popular power banks that include AC outlets, we scanned the top results on Amazon, Google Shopping, and the sites of major retailers such as REI and Target. We also considered models recommended by news outlets like Forbes, Popular Science, and The Verge.

We catalogued a range of features for each model we found, and we narrowed our search based on the following requirements:

This process left us with the following 11 models to test:

After spending 79 hours testing all 11 portable laptop chargers, we got to know them better than most dentists get to know their patients’ teeth. We tested the performance of each charger in a few key areas, including the following:

In previous rounds of testing, we measured noise levels using an RC Professional Decibel Meter, and we used an oscilloscope from BitScope to visualize the electrical waveforms of each charger. But since we had seen only minute differences in those areas among all the models we had tested in the past, we decided to forgo those tests for our 2020 and 2021 updates.

This compact, lightweight portable charger has an AC outlet, a USB-C PD port, and two USB-A ports, and it can charge even the most power-hungry laptops while they’re in use. Unlike many competitors, it also comes with a 45 W wall charger.

The Anker Powerhouse 100 is the portable laptop charger we’d buy for ourselves. With enough power output to keep a 15-inch laptop running, it charged our MacBook Air to nearly full even with the laptop's screen brightness cranked up and video playing. But even with that extra power, it's one of the smallest and lightest chargers we tested (the Omnicharge Omni 20+ is a few ounces lighter). It's ruggedly built yet sleek and professional looking, and its slim shape makes it easy to slip into a backpack pocket or briefcase. Plus, it's one of the few models that come with a wall charger.

In our peak-power tests, the Anker got up to 141 watts before shutting down, outperforming all but one model: the RAVPower 30000mAh AC Power Bank. With that much power, the Anker can handle large appliances like a room fan or a powerful laptop just as well as it can charge small devices such as a baby monitor or a rechargeable lantern.

The Anker recharges at top speed via its USB-C PD port when paired with the included 45 W wall charger and USB-C cable (you can use any USB charger and cable, which is convenient, but they might be more sluggish depending on their wattage). With the right cable, the USB-C PD port can also charge a small, handheld device such as a Nintendo Switch, a wireless mouse, or a smartphone as fast as possible. Its two USB-A ports are handy for charging small devices, too, albeit at a slower pace.

The Anker measures 7.9 inches tall, 4.7 inches wide, and 1.2 inches thick (about the size of a paperback novel) and weighs 1.9 pounds, a few ounces heavier than the newest iPads. It's flatter and smaller overall than the Jackery and Renogy chargers we tested, and it weighs nearly half a pound less than the RAVPower and ChargeTech models.

In addition to the wall charger and USB-C cable, this unit comes with a USB-A charging cable and a velvety-soft pouch. The latter is convenient for storing the unit and its accessories, as well as protecting the outer surfaces from scratches and dings.

The Anker's polished-metal shell has a sophisticated look, and the entire unit seems sturdy and well built. We especially like the rubber flap over the AC port, which prevents dust and other debris from sneaking into the port when the charger is getting jostled about in a backpack or a laptop bag. It also has a pleasantly textured rubber strip on one end that makes it even more impervious to damage, comfortable to hold, and easy to grip if you’re pulling it out of a bag.

At this writing, the Anker is one of the pricier models we tested, but not by much. Made by a company we trust, it's also backed by an 18-month warranty, which is as long as the coverage on any of our other picks.

When we charged an empty MacBook Air in our testing, the Anker Powerhouse 100 brought it up to 90% with the screen at full brightness, Wi-Fi on, and an HD movie streaming. Ideally we’d have preferred 100%, since the highest-capacity chargers we tested—the RAVPower and ChargeTech units—were able to fully charge the laptop (plus an additional 20%) under the same conditions. But considering that these power banks primarily serve to provide backup power between periods of access to wall outlets, we concluded that the Anker's extra portability was worth tolerating the slightly lower capacity.

The Anker has two features that are unique among the models we’ve tested: a nylon wrist strap and a built-in flashlight. These features feel superfluous to us—even if you’re planning to use your charger for camping or emergency preparedness, the flashlight isn't bright enough to be useful—and both extras somewhat detract from its otherwise sleek, stylish appearance. But they’re easy enough to overlook, and you can cut off the strap if you like (we removed ours after testing).

This model has plenty of ports, impressive capacity, and the power to charge most laptops. It's slim, sleek, and easy to use, and it comes with a wall charger. But it's heavier than the rest of our picks and not as ruggedly built.

*At the time of publishing, the price was $150.

The ChargeTech Portable Power Outlet 27K 4.0 offers the same input/output port options as the Anker Powerhouse 100, it's just as sleek looking, and it's compact enough to easily slip into a backpack or briefcase. It has a larger battery capacity than the Anker, and at this writing it costs a bit less. However, we decided not to make it our top pick because it's heavier and not as rugged: Its painted-metal exterior shows scratches and dings more easily, it doesn't have a protective flap over the AC port, and it doesn't come with a carrying case. Its output is slightly less powerful, too, and it comes with fewer accessories and has a shorter warranty. All things considered, though, it's a great option if the Anker is unavailable.

Like the Anker, the ChargeTech can power even large, powerful laptops like the Dell XPS 13 or MacBook Pro while they’re in use. In our testing, it pumped out 133 W of power to our test laptop, more than enough for most laptops or other household appliances that you might need to run while out of reach of a wall outlet, such as a room fan or movie projector.

In battery capacity, the ChargeTech bested the other candidates aside from the RAVPower 30000mAh, which it tied—both models were able to charge our MacBook Air test laptop 1.2 times. This extra capacity should offer some additional peace of mind if you’re working at a coffee shop, an airport, or anyplace else where wall outlets are scarce.

You can recharge the ChargeTech with the included 30 W wall charger and USB-C cable. (As with the Anker, you can also use any compatible USB wall charger and cable, though they may recharge the unit more slowly). It has the same port options as the Anker, too—an AC outlet, two USB-A ports, and a USB-C PD port—so it can charge most devices.

Measuring 8.0 by 5.4 by 1.2 inches, the ChargeTech is about the size and shape of a paperback novel. Its slim profile and smooth exterior give it a sleek look and make it easy to slip into a backpack or briefcase. However, at 2.4 pounds it's the heaviest of our picks, weighing about as much as a liter of soda. We also found that its painted-metal shell is not resistant to scratches, scuffs, and dings. Unfortunately, it doesn't come with a carrying case to protect it, nor does it have a rubber flap over any of its ports to keep out lint and crumbs, like some of the other models we tested. If you buy one, handle it with extra care.

At this writing, the ChargeTech costs just a little less than our Anker pick and a little more than the model from RAVPower. We’ve had good experiences with ChargeTech's products and customer service, and if you run into any issues with this unit, it's backed by a one-year warranty.

This compact, lightweight charger supports wireless charging and has an OLED screen that displays battery life and other metrics. It's not quite as powerful as our other picks, and it doesn't come with a wall charger, but it recharges with any compatible DC or USB-C charger.

*At the time of publishing, the price was $200.

The Omnicharge Omni 20+ is one of the most expensive models we’ve tested, but it's also one of the few options with wireless charging, two ways to recharge (via DC or USB-C PD), and a screen showing helpful information like input/output power, percentage charged, and operating temperature. It's the smallest and lightest of our picks, yet it still offers all the same ports. And like our top pick from Anker, it's ruggedly built, sleek, and professional looking. Beyond its high price, the biggest downsides of the Omni 20+ are that it has the lowest output and capacity of any of our picks, and it doesn't come with a case or wall charger. But if you want the extra charging options it provides and don't mind paying a premium for them, it's your best bet.

In our testing, the Omnicharge topped out at 98 W of power output—less than our other picks, but still plenty of power to charge most laptops while they’re in use. It brought our MacBook Air from 0% to 80% charged, which again was less than our other picks managed, but not by much.

The Omnicharge comes with both USB-A and USB-C cables, but you’ll have to supply your own wall charger. Since most laptops are powered by a USB-C or DC wall charger, you might already have one on hand that's compatible with this unit. If you don't already have a suitable charger, Omnicharge sells a charger separately or in a bundle with the main unit, but we don't recommend either one. The wall charger is difficult to put together—it stymied us, and we had to ask customer support for help—and you can typically get one of our favorite wall chargers for less.

The ports on this unit are widely spaced, leaving ample room for multiple plugs. It has an AC outlet on one side and offers USB-C PD and DC input/output ports on another. On a third side, you’ll find two USB-A output ports, an OLED display screen, and control buttons to toggle various ports on and off. This unit also has a Qi wireless-charging feature (though it's not certified by the Wireless Power Consortium, which we’d prefer for confirmation of safety and optimal performance) that you can use to charge some newer phones. This feature is definitely not necessary for everyone, but it's nice to have if your device is Qi-compatible.

The Omnicharge is about the size of a bagel or kaiser roll. It has a square shape with gently rounded corners that make it easier to hold or to stuff into a bag. At 1.4 pounds, it's the lightest of our picks. Its outer shell is made of a soft-textured plastic that's grippy and comfortable to hold, and it seems relatively scratch and scuff resistant. After you handle it for a while, its surface is likely to gain some fingerprints, but they won't be nearly as noticeable as on the RAVPower 30000mAh. Overall, it has an upscale, professional look.

We wish this unit came with a protective case, as our Anker and RAVPower picks do, though in practice this omission probably isn't a big deal—most people are likely to carry their charger around in the same bag as their laptop, phone, and other important belongings, so they’ll probably handle it with care. What would have made a real difference is a rubber flap over the Omnicharge's ports (which, again, the Anker and RAVPower models have) to protect its internal components against dust and minor spills, but that piece is also missing here.

The Omnicharge's OLED screen, unique among our picks, is bright and generally informative. When you’re recharging the unit, it displays a large battery icon to show how much charge it has, which is clear and helpful. But when you’re using it to charge another device, the screen offers so much information—wattage, voltage, temperature, percentage charged, and what ports are currently powered on—that the display can feel cluttered, which makes it harder for you to get headline info at a glance. Still, if you like to keep close tabs on how much power your laptop is getting or precisely how much battery life your device has left, you might find that level of detail advantageous.

At this writing, the Omnicharge is one of our more expensive picks. But as the brand's name suggests, this model also offers the most charging options. Its one-year warranty isn't as long as those that come with some of our other picks, but we still think the coverage is long enough for you to fully test the charger and confirm that you don't have a dud. When we emailed Omnicharge's customer support, representatives responded within a few days, so if you do run into an issue, you can count on timely assistance.

This unit cranks out 149 W—the most power of any of our picks—and its battery capacity is as high as that of any charger we’ve tested. It's heavier than most, weighing over 2 pounds, but it performs as well as or better than pricier models.

The RAVPower 30000mAh AC Power Bank (RP-PB055) is the least expensive of our picks, yet it's also a smidgen more powerful. It has just as many ports as our other picks do, and its capacity is as high as that of any model we’ve tested. It's not as sleek looking or as portable as our other picks—even without its hard-shell case, it's on the bulkier side, it weighs over 2 pounds, and its rubber shell is a smudge magnet—and unlike our other picks it doesn't come with a wall charger. But if you’re looking to save some cash without sacrificing much utility, this charger fits the bill.

In our testing, this unit had the highest peak-power performance of any model we tried, cranking out an impressive 149 W of power. That means you could plug in a 15-inch MacBook Pro running several programs, as well as a phone and a couple of other small devices, without overloading it.

This charger also reigns supreme when it comes to battery capacity. It was able to charge our MacBook Air from 0% to 100%, and then again from 0% to 20%, on a single charge. In terms of battery-charge percentage, that's equal to what the ChargeTech provided, 20% more than we got from the smaller (discontinued) RAVPower model we tested, 30% more than the Anker produced, and 40% more than the Omnicharge managed.

The RAVPower 30000mAh's outer surfaces are coated in a rubbery material that, while comfortable and grippy, causes it to collect smudges and fingerprints more easily than any other model we’ve ever tested. But that's a pretty small quibble, especially since it comes with a soft, mesh pouch as well as a roomy, hard-shell case. It also comes with a USB-C charging cable, but sadly without a wall charger; you’ll need to get one that supports USB-C PD charging to recharge it at top speed.

Although this unit still feels relatively sleek and compact, at 7.0 by 5.4 by 1.8 inches it's the biggest charger we’ve tested. Weighing 2.2 pounds, it's also one of the heaviest. But those are reasonable trade-offs for the extra power it gives you.

Like the rest of our picks, the RAVPower 30000mAh has a single AC outlet—and, like our top pick, it covers that outlet with a protective rubber flap to keep out debris. It also has two USB-A ports, which are powerful enough to charge most handheld devices. Its USB-C PD port works for either input or output, as well; this means you can use the port to charge a device such as a Nintendo Switch or 13-inch MacBook Pro, or you can plug it into the wall and recharge the unit itself, at top speed (provided you pair it with the right cable and wall charger).

Not only is this charger the least expensive of our picks at this writing, but it also has one of the longest warranties at 18 months. In addition, we’ve found the company's customer support team to be responsive and helpful.

The Goal Zero Sherpa 100AC Power Bank is fairly compact, enjoyable to use, and equipped with an informative OLED screen. In our testing, it had the highest peak-power output (160 W), and it charged our MacBook Air from 0% to 95% on a single charge. But at this writing, it's also the most expensive model we tested. In addition, it's one of the heaviest chargers we’ve seen, tied with the Naztech Volt Power Station at 2 pounds (though still a little lighter than our ChargeTech and RAVPower picks).

The Mophie Powerstation AC used to be our top pick, but it has been discontinued. It's still a great choice if you can find it, though, with a 79.2 Wh battery capacity and 123 W maximum output in our testing. It has a USB-C PD port, a USB-A port, and an AC port with a protective rubber flap. It weighs just 1.7 pounds, it's small and compact, and it's covered in a soft twill fabric that we love.

If you don't need an AC outlet, our favorite high-capacity power banks can charge laptops and other USB-powered devices, and they’re smaller and lighter than the picks in this guide.

The ChargeTech 27K AC Battery Pack and RAVPower 27,000mAh AC Power Bank are former picks that have been discontinued and replaced with newer versions (our runner-up pick and budget pick, respectively).

At 1.5 pounds, the Jackery PowerBar 23200 (discontinued) was one of the lightest models we tested, and its two-year warranty was as good as any we saw. It was one of the least expensive models we tested, and it seemed well built. However, due to its brick-shaped design, it wasn't as sleek or portable as the others—it was a lot tougher to slip into a briefcase than the book-shaped chargers, and multiple Wirecutter staffers said they would prefer a slimmer design. Also, as soon as we turned on the AC output, its fan became audible, which could be distracting in a quiet room.

The Naztech Volt Power Station AC Outlet 14149 has one of the best warranty periods (two years) and currently costs the least of the chargers we tested. It shares some aspects of our picks, offering a clean, simple look and good capacity. However, along with the Goal Zero, it's one of the heaviest chargers we tested, weighing 2 pounds. It's also one of the biggest, measuring 6.9 by 5.3 by 1.4 inches, and its AC/DC charger is a bit bulky. It had the lowest peak-power output (95.1 W) in our testing, and it's one of the most finicky chargers to control when you need to turn the power—or even the flashlight—on and off. Lastly, we’ve had little experience with Naztech and the Volt brand, and when we contacted the company's customer support, a response took 17 days, which doesn't bode well for customers if something goes wrong.

The Renogy Phoenix 100 Mini Power Station has the same brick shape (and roughly the same size and weight) as the Jackery PowerBar, so it's less portable than thinner, book-shape options, which fit better in laptop bags and backpacks. It also cost about the same as the PowerBar at the time of our research, and it has one fewer USB-A port. It does provide an additional input option (Micro-USB) that none of the other tested models offer—but since charging is painfully slow over that port, that feature doesn't offer much of a benefit.
