FYI
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 a variety of other devices, from vibrators and video projectors to breast pumps and baby monitors.
We’re confident the Mophie Powerstation Pro AC is the best portable charger with an AC outlet that you can buy. It keeps up with MacBook Pros and other powerful laptops, it has a compact size and shape, and its battery life is as good as any we’ve tested.
Our pick
Mophie Powerstation Pro AC
This portable charger has an AC outlet, two fast-charging USB-C ports, and a USB-A port, and it can charge even the most power-hungry laptops while they’re in use. But you need to provide your own wall charger.
The Mophie Powerstation Pro AC has the best AC output (174 watts) and as much capacity (27,000 mAh) of any model we’ve tested.
It’s also the only one we’ve tested with two USB-C ports—one has 63 W input and 62 W output capabilities, and the other only outputs at 24 W—and its two-year warranty is the longest of those we tested.
On the downside, it’s the heaviest option we tested at 2.2 pounds, it only has one USB-A port, it doesn’t come with a wall charger, and it’s on the pricier side ($200 at this writing). But its higher output and dual USB-C ports make it well worth the splurge.
Rated capacity: 27,000 mAh (97.2 Wh)
Max output: 174 W
Weight: 2.
2 pounds
Dimensions: 7.5 by 4.5 by 1.0 inches

Budget pick
ChargeTech Premium 27K AC
This more affordable charger has a fast-charging USB-C port, a standard USB-A port, and an AC outlet that cranked out an impressive 157 W of power in our testing. Plus, it comes with a wall charger.
The ChargeTech Premium 27K AC performed well in our testing, with a maximum output of 157 watts and a rated capacity of 27,000 mAh.
It’s also the only model we tested with a USB-C port that’s powerful enough to fast-charge the 13″ MacBook Air (we measured 65 W input and 67 W output). Unlike our top pick, it can be recharged over DC as well as USB-C, it’s fairly light (1.5 pounds), and it’s the least expensive of those we tested ($185 at this writing).
However, it has just one USB-C port and one USB-A port, its one-year warranty is on the shorter side, and it feels a little chintzy overall.
Also, the DC charger it comes with is bulky and won’t fit in the included carrying pouch. But overall, it’s a great option if you’re on a tight budget.
Rated capacity: 27,000 mAh (97.2 Wh)
Max output: 157 W
Weight: 1.5 pounds
Dimensions: 7.3 by 5.0 by 1.0 inches
Also great
Omnicharge Omni 20+
This compact, lightweight charger supports wireless charging and has an easy-to-read screen. It’s not as powerful as our other picks and doesn’t come with a wall charger, but it recharges via most USB-C or DC chargers.
If you have a phone or other device that can charge wirelessly, the Omnicharge Omni 20+ is the only one of our picks with wireless charging capabilities. It’s also one of the few models we’ve seen with dual input options (you can recharge it over DC or USB-C), as well as a screen showing input/output wattage, charge level, and operating temperature.
The Omnicharge is the lightest (1.4 pounds) and most compact of our picks, and it looks sleeker than most models, with rounded corners that make it comfortable to handle.
If you want those extra features and maximum portability, this is your best option, but this charger also has the lowest output (98 watts) and capacity 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 W
Weight: 1.4 pounds
Dimensions: 5.0 by 4.8 by 1.1 inches

Why you should trust us
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 29 hours researching and 82 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.
Who this is for
Portable laptop chargers aren’t just for laptops. Since they’re power banks with AC outlets, they can provide power to virtually any device that draws up to about 100 watts—such as a room fan, floor lamp, air mattress pump, or ice cream maker.
But since most people who buy these chargers are mainly looking to charge their laptops while working remotely, 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.
)
Even someone who is rarely away from their desk might want a portable laptop charger in case of a blackout or other emergency. A portable laptop charger will provide more power in that scenario than a USB power bank.
If you want to charge lots of different devices, or a single power-hungry device, for more than a few hours—or if you have critical electronics that require a pure sine wave inverter, such as a CPAP machine—you should get a portable power station. Generally speaking, these have more capacity, power, and ports than most portable laptop chargers, and they’re more ruggedly built (but they also tend to be bulkier, heavier, and more expensive).
How we picked and tested

After scanning the websites of major retailers and consumer-electronics brands, we narrowed our search based on the following requirements:
- 65-watt or greater output: Most laptops (larger business and gaming laptops aside) need about 60 W to charge at full speed, so we set our minimum limit at 65 W just to be safe.
- 60 to 300 watt-hour capacity: TSA regulations generally only permit you to carry spare batteries up to 100 Wh on a plane—or, with airline permission, either one battery up to 300 Wh or two batteries up to 160 Wh each. Since some people like to work or watch movies on their laptop on long flights, we capped our capacity limit at 300 Wh to account for this restriction. We set our minimum at 60 Wh because that’s equivalent to running a 60 W device (such as a 13-inch MacBook Pro) for one hour.
- Light and compact design: We gave preference to smaller, lighter models since they’re easier to bring to a coffee shop or on a plane.
- At least one fast-charging port: USB-C Power Delivery (PD) ports are starting to replace older USB-C and USB-A ports, in part because they can transmit up to 100 W (compared with just 15 W over standard USB-C and 12 W over USB-A). This means, with the right cable, they can charge a laptop or other compatible device about as fast as an AC outlet would.
- At least one USB-A port: Even though USB-C is becoming more common, most people still have standard USB-A charging cables, so we insisted that our picks have at least one USB-A port.
- Reliable support: If you’re spending hundreds of dollars on something and depending on it in tight situations, you want to know that the manufacturer is reputable and reachable in case something goes wrong.
- A cost of no more than $300: Based on the range of prices we saw, this is what we think someone would reasonably want to spend on a work-related purchase.

To test each charger, we gauged performance in a few key areas, including the following:
- Maximum power output: To test the maximum power output of each model, we connected each one to a Kill A Watt power meter and an array of light-bulb sockets. We screwed in 20 W halogen bulbs one by one until the charger overloaded and shut down. Then we recorded the maximum wattage reading on the power meter.
- How many times each charger could recharge a laptop: We started with a fully depleted 2015 13-inch MacBook Air and a fully charged portable laptop charger. Once the charger had juiced the laptop enough for it to power on, we maxed out the screen brightness and played a loop of high-resolution railway footage on YouTube. We let it run until the portable charger died or the laptop reached a full charge. If the laptop reached 100% before the portable charger died, we fully drained the laptop again and repeated the test with the partially charged portable charger to find the combined total number of recharges.
- Ability to charge a 15-inch MacBook: To make sure all of the chargers could power a large, high-powered laptop, we connected them to a 15-inch MacBook Pro that normally uses an 87 W power adapter and checked the Mac System Report to make sure it wasn’t struggling to get enough power.
- Look and feel: We picked the chargers up, stuffed them into a crammed backpack, and carried them around to see how they would fit into our lives. We also assessed extra features, such as a screen or battery-status lights.

Our pick: Mophie Powerstation Pro AC
Budget pick: ChargeTech Premium 27K AC

Budget pick
ChargeTech Premium 27K AC
This more affordable charger has a fast-charging USB-C port, a standard USB-A port, and an AC outlet that cranked out an impressive 157 W of power in our testing. Plus, it comes with a wall charger.
If you want to save a few bucks without losing many of the features or capabilities of our top pick, get the ChargeTech Premium 27K AC.
It has plenty of power. Like our top pick, this model can charge even large, professional-grade laptops without breaking a sweat. In our testing, we measured a peak-power output of 157 W (not far behind that of our top pick) from its AC outlet.
It’s also the only model we tested with a USB-C PD port that’s powerful enough to fast-charge the latest MacBook Air and MacBook Pro models: We measured a maximum output of 67 W.
Like our top pick, the ChargeTech has a single USB-A port, which is handy for charging a phone, wireless headphones, or other small device—albeit more slowly than a USB-C port.
It has great battery life. Just like our top pick, the ChargeTech has a rated capacity of 27,000 mAh, and it performed just as well as that model in our capacity tests.
It has multiple recharging options. Unlike our top pick, the ChargeTech can be recharged over DC as well as USB-C. While we didn’t test its DC input capabilities, we measured up to 65 W flowing into the USB-C PD port (meaning it can recharge itself a bit faster than our top pick).
It’s small and lightweight. Weighing just 1.5 pounds (about as heavy as a bottle of beer) and about the same size and shape as our top pick, the ChargeTech is highly portable.
Its warranty is on the shorter side. ChargeTech backs this model with a one-year warranty, which is shorter than that of our top pick, but it should still give you plenty of time to use your unit and ensure it’s not a dud.
It comes with a charger, but it’s bulky. Unlike our other picks, the ChargeTech helpfully comes with its own charger. However, the proprietary DC charger has a fat plug that takes up a lot of space in a bag (and, annoyingly, the power bank and its charger don’t fit in the included soft pouch).
It’s inexpensive (and it shows). As one of the least expensive portable chargers we’ve tested ($185 at this writing), the ChargeTech feels a little chintzy overall. So if build quality is important to you, go with one of our other picks.
Also great: Omnicharge Omni 20+

Also great
Omnicharge Omni 20+
This compact, lightweight charger supports wireless charging and has an easy-to-read screen. It’s not as powerful as our other picks and doesn’t come with a wall charger, but it recharges via most USB-C or DC chargers.
The Omnicharge Omni 20+ is one of very few available options with wireless charging, as well as a screen showing helpful information like input/output power and operating temperature. It is pricey and has less capacity and output power than our other picks, but it’s your best bet if you want these features.
It can charge your phone wirelessly. 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 phones and other devices.
It’s exceptionally compact and lightweight. 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. And at 1.4 pounds, it’s the lightest of our picks.
It has well-spaced ports. The ports on this unit are widely spaced, leaving ample room for multiple plugs.
It has an AC outlet on one side, and 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.
It has an upscale, professional look. 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, however.
Its screen is bright and informative, if sometimes cluttered.
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 data—wattage, voltage, temperature, percentage charged, and what ports are currently powered on—that the display can feel cluttered, making it harder to glean key info at a glance.
Capacity and output are on the low side, but sufficient for most needs. 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 no charge to 80% charged, which again was less than our other picks managed, but not by much.
It comes with cables, but not a wall charger. 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, and you can typically get one of our favorite wall chargers for less.
Its ports aren’t protected. We wish this unit came with a rubber flap over its ports to protect its internal components against dust and minor spills, as several other models we’ve tested do.
Product support is solid. Its one-year warranty isn’t as long as that of our top pick, but we still think the coverage is long enough for you to fully test the charger and confirm that it doesn’t have a problem. Customer service is responsive, too.
It’s not cheap. 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.
Other good portable laptop chargers
If you don’t mind buying a discontinued product: Get the Anker PowerHouse 100 or Mophie Powerstation AC.
Both are former top picks, but since they’re discontinued they may be difficult to find. They’re still being sold by some retailers, though, and either would be a great substitute if our current top pick becomes unavailable—or if you see a good deal.
The Anker PowerHouse 100 performed well in our testing, providing a maximum output of 141 W and a 27,000 mAh rated capacity—enough 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 PD port, two USB-A ports, and an AC outlet. And unlike most portable chargers, it 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.
Similarly, the Mophie Powerstation AC has a peak-power output of 123 W, a 22,000 mAh capacity rating, and a good selection of ports: a USB-C PD port, a USB-A port, and an AC outlet.
It doesn’t come with a charger, but it’s small and compact, weighing just 1.7 pounds. Plus, it’s covered in a soft twill fabric that we love.
What to look forward to
Goal Zero has introduced a new version of the Sherpa 100AC Power Bank, which improves on the original with an angled color LCD and faster wired and wireless charging. We plan to test it soon.
The competition
This is not a comprehensive list of all portable laptop chargers we’ve tested and dismissed. We have removed models that are discontinued or do not meet our current criteria.
The Goal Zero Sherpa 100AC Power Bank (original version) had a 160 W output in our testing, and it charged our MacBook Air up to 95% on a single charge.
It’s fairly compact, enjoyable to use, and equipped with an informative OLED screen, too. But was also the spendiest model we tested at $300, and it didn’t offer any extra features that justify this price jump. However, as of this writing, open box copies are on final sale with a large price cut that may make this charger a better option for the right buyer.

Best portable laptop battery chargers and power banks of 2023
When you purchase through links on our site, we may earn an affiliate commission.
Here’s how it works.
(Image credit: Future)
Having the best laptop power bank or battery charger in your portable arsenal is a good idea, especially if you do a lot of traveling or like to squeeze in some more work while commuting to and from the office. These days, you shouldn’t go anywhere without one.
While the battery lives of many of the best laptops are now longer than ever, longevity still depends on how demanding the tasks they handle are. And, it’s not like you can find an outlet anywhere – even big-name coffee shops like Starbucks are making outlets inaccessible to patrons.
The good news is that many laptops today are designed with USB-C charging available. So, just like regular power banks for smartphone-dependent teenagers, laptop battery chargers have fast become an integral part of any professional’s setup, specifically those who work remotely or enjoy working at a cafe. And, just like regular power banks, they come with various port options – some even come with an AC outlet for those whose laptops do not offer USB-C charging.
Getting a portable laptop battery charger or power bank isn’t as straightforward. You should check to see what laptops the chargers support, as some laptops still come with proprietary chargers, and ensure that it has the right connector to plug your laptop in. You’ll need to consider how much power they supply, as particularly power-hungry laptops, such as gaming laptops, may not work with them. Finally, check how large their internal batteries are, as this will dictate how many times the charger can charge a laptop, and their overall size, as you don’t want to lug around a large and heavy charger.
As complicated as that sounds, you will find that the ideal laptop charger or power bank is worth all the effort. Besides, we’ve gathered the best portable laptop chargers 2023 offers to save you time and hassle. Take a look at our top picks below.

It has its own jump start port and comes with its own jumper cables. And, unlike other portable laptop chargers, which only come in one or two colors, this one comes in seven different colors/design patterns, making it ideal for folks who don’t care for the minimalist approach. Unfortunately, it doesn’t have a USB-C port, and the AC outlet should take care of most of your laptop charging needs.

This incredibly high-capacity laptop power bank might have too much power to take on a flight.
However, it’s ideal for long road trips. It’s also incredibly versatile, with 28 different laptop connectors and a Magsafe 2 adapter to accommodate just about any laptop under the sun. The laptop charger also has a passthrough function that can be easily turned on and off and a LED display that shows the voltage and current battery level. Unfortunately, even though it is the highest capacity charger on this list at 50,000mAh, it can fully charge in 6-8 hours – charging overnight is obligatory.

The Voltaic Systems V88 Portable Laptop Power Bank has all the necessary features that any great laptop power bank should have, including four outputs, passthrough functionality, and an easy-to-read LCD display for monitoring the battery level and voltage.
It’s fairly versatile, including 10 laptop adapters that should cover most users’ needs. At 88Wh, it’s also airplane-friendly. The Voltaic power bank is unique, though, because it’s solar-optimized. This means it works with solar chargers and solar panels when traditional power sources are unavailable. While those have to be purchased separately, this feature makes the Voltaic Systems V88 particularly useful for those going off-grid.

Notebooks, netbooks, ultrabooks are chosen for their portability and battery backup, on which they work after being disconnected from the mains. Battery operation is convenient when traveling if there are no outlets nearby, or if you don’t like extra cables getting in the way. Laptops use lithium-ion batteries (Li-Ion), sometimes lithium-polymer (Li-Polymer). The lithium polymer battery is an advanced lithium ion battery. It is important to remember that every laptop battery has charge and discharge cycles. Battery life varies from 2 to 3 years, after which the battery charge gradually decreases and soon the battery does not hold a charge at all.
That’s why it’s better to replace the battery. Buying a laptop battery is more reliable and more profitable than repairing an old one.
Chinese manufacturers offer to buy original batteries for laptops of popular brands. Do not intend to overpay for the brand? Manufacturers in China produce batteries under OEM contracts, and such batteries are not inferior in quality, but their prices are lower than original batteries.
In addition to internal laptop batteries, we offer prompt delivery of external batteries from China. When choosing an external battery, pay attention to the capacity, weight, dimensions, number of USB outputs and current strength.
We will help you with the delivery of bulk consignments from China with subsequent customs clearance. In the case of complex work with us, we will provide all closing documents and certificates. We use door-to-door delivery through Kazakhstan, so we deliver goods in 25 days. To order wholesale delivery of laptop batteries from China, send us the package and invoice to zakaz@sapsanplus.

Backup battery Toshiba CB17 20mah
- Approximately 500 charge-discharge cycles until the battery capacity reaches 70%
- Service life of at least 2 years
- Can be charged at any time and does not have to be completely discharged (no “memory effect”)
- Has a built-in charge controller that protects against overheating and overcharging.
9 0003 Low self-discharge characteristic of high-quality lithium batteries
All batteries are safety tested and certified, ISO 9001:2008.
All recommendations and warnings apply to Li-ion, Li-polymer batteries only.
Charging
-
How do I start using a new battery?
Lithium battery must be charged before first use! Only new Ni-Cd, Ni-MH batteries are discharged before use, while lithium batteries need to be charged!
It is recommended to make three complete charge-discharge cycles for the device to determine the full capacity of the battery. Each cycle includes charging for at least 3 hours and then completely discharging the battery.
Do not leave the battery empty, charge the device immediately. These cycles are necessary for your device to use the full capacity of the new battery.
-
How to charge the battery?
Use the charger and cable supplied with the device, regardless of the capacity of the new battery (more or less).
Fast charging does not depend on the battery, if the device supports it, it will also work after replacing the battery.
-
Memory effect
None (does not require “training” and “calibration”), but several charge-discharge cycles are required for a new battery (after replacing the old one).
Storage
-
Date of manufacture
Date of manufacture is indicated in the serial number. Example: C11x04xx or A11x04xx – 2019 4 months, C12x06xx or A12x06xx – 2020 6 months. From 2022, 2202Nxx is indicated, where 22 is the year, 02 is the month.
-
Shelf life
A 30-50% charged battery can be stored for no more than 2 years at a temperature of 0 – 25 °C. In this case, the battery loses no more than 4% capacity per year.
Service life
-
What causes the battery to deteriorate
Very hot during charging or use. For example in the sun, near heaters. This does not apply to natural heating during charging or operation.
Heavy duty. They do not reduce the resource as much as other reasons, but frequent loads can significantly reduce the service life.
Cold charger. Charging the battery at temperatures below 5°C greatly reduces the resource.
Mechanical damage. Damage to the sealed packaging of the battery increases the risk of complete failure.
Storage in a discharged state. Also, long storage with the battery connected drains it faster and often the device can no longer charge it.
Incompatible charger. A charger with a lower capacity can charge more slowly and also reduces the resource.
The battery is defective, signs
-
Discharges quickly
Turns off abruptly, it was 50% and immediately 20% most often this is due to a battery malfunction.
-
Won’t turn on
Diagnosis required, but battery replacement does not always solve the problem.

Finding the cause of the problem in order of verification:
1. replace the cable,
2. replace the charging adapter,
3. clean the charging port on the device itself,
4. replace the battery.

-
What is the danger of the battery
The absence of damage and stress in the operation of the battery practically guarantees its safety. The degree of assurance is illustrated by the following comparison from the US National Oceanic and Atmospheric Administration:
• the chance of becoming a victim of lightning during a person’s lifetime is about 1 in 13,000;
• 1 in 10,000,000 chance of accidental ignition of a lithium-ion battery. Read more in this article. -
