I like to occasionally get away from my desk and work on my laptop in public places. What I do not like is the desperation that comes from hunting down the only available outlet in whatever coffee shop, coworking space, airport terminal or library I find myself in. So I always try to pack a laptop power bank in my backpack. The one I usually bring is Anker's version with a retractable cable but I've tested more than a dozen others and have recommendations for budget and travel models too. Here are the best laptop power banks according to a few years of testing, along with a quick breakdown of power bank facts to help you get the most out of your new battery.

Best laptop power banks for 2026
Capacity: 25,000 mAh | Ports: 1 x USB-A, 1 x USB-C and 2 x USB-C cables | Maximum combined output: 165W | Size: 6.2 x 2.1 x 1.9 in | Weight: 21 oz | Digital status display: Yes | Warranty: 1 year
This is the bank that comes with me when I need to work from the coffee shop up the street. The Anker Laptop Power Bank has two built-in USB-C cables, one that retracts into the body of the battery and another that acts as a handy carry strap. The display shows you the amount of charge left and how much wattage you're currently drawing (it also smiles and makes funny faces when you yank on the retractable cable — cute).
It got my 16-inch MacBook Pro from 10 percent to 78 percent in about 50 minutes, but I most often use it to refill my phone (and sometimes accessories like my earbuds and mouse). It charged a Galaxy S23 Ultra from five percent to full in around 50 minutes as well. The best part about the bank is that I don't have to remember to bring an extra cable along. Either of the built-in cords can be used to charge the battery itself, which means I don't have to hunt down a cable at home either.
- Built-in cables are convenient
- 165W combined charging speeds deliver a fast charge
- Display is accurate, useful and cute
- Large display screen is easily scratched
- Expensive when not on sale
Capacity: 25,000 mAh | Ports: 2 x USB-C, 1 x USB-A | Maximum combined output: 145W | Size: 6.3 x 3.2 x 1.1 in | Weight: 17.8 oz | Digital status display: Yes | Warranty: 2 years
The UGreen 145W Laptop Portable Charger has a list price of $100 but is almost always on sale for around $70. It has a simple design that packs three ports and a small display for monitoring the remaining charge. One of the USB-C ports can deliver up to 140W, which is the max for the entire bank — meaning if you use other ports at the same time, the wattage from that port will go down.
It was able to fill my laptop from 10 percent to 81 percent in around 90 minutes. Separately, it filled an iPhone 15 from near-dead to full in about 95 minutes, which is one of the faster times I've measured. True, there are cheaper laptop banks out there — but considering the heat-regulating tech, voltage converters, insulation and other components that go into making a battery safe, I don't recommend going for the super cheap models.
- Excellent capacity for the price when it's on sale (which is often)
- Comes with a USB-C cable
- Just three ports can be limiting
- Somewhat basic design
Capacity: 27,000 mAh | Ports: 1x USB-C (100W), 1x USB-C cable (140W), 1x USB-A | Maximum combined output: 200W | Size: 6.4 x 2.1 x 2.0 in | Weight: 23 oz | Digital status display: Yes | Warranty: 3 years
ReelCharge is a new accessories brand started by ex-Satechi execs. The ReelPro 200W is one of their first batteries and a promising first move. The compact brick holds 27,000mAh — which is the maximum allowable capacity for a carry-on according to FAA and TSA regulations. That translates to about four or five refills for a standard smartphone, about 80 percentage points on large laptops or a full charge for lighter notebook computers.
It has a handy built-in, 11-inch long USB-C cable so you'll never be without a way to charge a device. And the built-in display accurately lets you know how much charge the battery has left to give.
A hefty 200W maximum output rate means it can refill devices pretty quickly. It got my MacBook Pro from 4% to 86% in just over an hour — and that's while I was using my computer. Charging an iPhone was super fast too, getting from near-dead to full in about 95 minutes.
Overall, the battery charges devices faster and has a bit more charge to give than our top pick from Anker, plus they're both the same price. I still prefer the Anker bank for its dual cables, one of which is extra long and retractable, but if you're looking for something new and fast, this is a great pick.
Capacity: 26,250 mAh | Ports: 2 x USB-C (140W), 1x USB-A (22.5W) | Maximum combined output: 300W | Size: 6.3 x 2.5 x 1.5 in | Weight: 21 oz | Digital status display: Yes | Warranty: 2 years
The Anker Prime Power Bank can deliver up to 300 watts of power if you use all three ports at once. That would require you to have two devices hooked up to the USB-C ports that can ingest 140 watts each and another plugged into the USB-A port. Unless you've got two massive laptops (and a phone) that all need refills simultaneously, it's unlikely you'll take advantage of the max wattage.
But that does mean whatever you plug in should charge as fast as it's able. When I used it for my MacBook Pro, it got my laptop from 10 percent to 75 percent in about 45 minutes. That's the fastest of any battery I've tested.
The power bank itself is compact and feels solid. There's a display that shows you how much charge remains, how much power is jetting through each port and the battery's current temp. It also makes a cute animation when you set it on the optional charging base . That accessory is not necessary, to be clear, but it is convenient and acts as a little charging hub with its extra ports. Of course, it also makes an already pricey power bank even more expensive — but if speed is what you're after, this bank delivers.
- Extremely fast charging
- Optional base offers a convenient recharge
- Display and (optional) app provide lots of info
- Expensive
- Shiny front may get scratched
- Just three ports
Capacity: 27,000 mAh | Ports: 1x USB-C, 2 x USB-A, three wireless pads | Maximum combined output: 100W | Size: 8.5 x 3.5 x 1.3 in | Weight: 32 oz | Digital status display: No | Warranty: 5 years
The Lion Eclipse Mag is a beast of a bank. It's heavy at two pounds and has a rugged, rubberized exterior. It's got a big 27,000 mAh capacity, which puts it at the upper limit of what TSA will allow you to carry on an aircraft. And instead of only offering ports, it has three charging pads to accommodate an iPhone, AirPods and an Apple Watch. The USB-C port can output up to 85W to recharge your laptop, and it refilled mine from 10 to 89 percent in 78 minutes.
In theory, you could charge your phone, accessories and laptop all at once, but that will really cut down on speeds. I've found it works best as a laptop savior during the day, then as a three-in-one wireless charger back at your hotel, as you can refill the battery while using the wireless pads. There's no display, only one USB-C port and one Type-A outlet, which cuts down on the number of things you can charge at once. But if you're traveling with your full arsenal of Apple gear, this is a handy battery.
- Three ports and three wireless charging pads
- Doubles as a charging station
- Large capacity for the price
- Doesn't make sense for non-Apple users
- Heavy
Capacity: 25,000 mAh | Ports: 1 x USB-A, 2 x USB-C (100W), 1 x USB-C (15W), one wireless pad | Maximum combined output: 120W | Size: 5.4 x 4.4 x 1.4 inches | Weight: 21 oz | Digital status display: No | Warranty: 2 years (3 years if purchased through Biolite)
The rugged Biolite Charge 100 PD is refreshingly not gray or black, and the rounded corners and blocky design make it easy to pack. It has three USB-C ports (two of those can output a respectable 100W) and a wireless charging pad up top that maxes out at 15 watts. The charging pad has some magnets to help the bank align with MagSafe-compatible iPhones and Pixelsnap-enabled phones. But the attachment is not strong enough to hold the phone on the move (in other words, keep the battery on a table during wireless charging).
It was able to get my laptop from 10 to 85 percent in under an hour and speedily refilled my Galaxy S23 Ultra in a little over an hour. A wireless charge on an iPhone 15 took about two and a half hours.
There's a lot to like about the company, too. Biolite is a certified B-Corp that helps provide lights and safer cookstoves to impoverished areas around the world.
- Attractive and tough design
- Four ports plus a wireless charging pad
- Company is a certified B-Corp
- No digital display
How we test laptop power banks
I've tested dozens of batteries over the past few years. Before I start physically testing a battery, I read the reviews on Amazon and the manufacturer's sites as well as verdicts from other publications to make sure the batteries are worth the time to test them.
To test laptop power banks, I fill each battery to capacity then use it to recharge phones (both Apple and Android), my iPad Air (11-inch, M1) and my work computer (16-inch MacBook Pro M1). I note the time it takes to go from nearly dead (5 percent for phones, 10 percent for a laptop) to 100 percent or when the battery depletes its charge.
In the case of the phones, I don't use them as they recharge. But I do use my laptop as the batteries recharge. The setup is likely how most people will use a laptop battery: connected to Wi-Fi, using a VPN and running apps like Slack, Photoshop and Chrome with multiple tabs open.
To pick the best models, I look at the number of ports, capacity, design and performance as compared to the price to decide which are most worth your money. As new models worthy of testing come to market, I will test them and will update this guide accordingly.
Laptop power bank FAQs
Are laptop power banks the same as phone power banks?
Laptop power banks are usually much bigger so they can handle the batteries inside laptops. Power banks meant for phones often have a capacity from around 5,000 milliamp hours (mAh) to 15,000mAh and output a lower wattage, often at levels too low to give a charge to a laptop. So most power banks that would qualify as a laptop power bank will be rated between 20,000mAh and 27,000mAh and have ports that can output 60 to 100 watts. Laptop power bank capacity typically stops around 27,000mAh as that matches the TSA's 100Wh limit for batteries you can put in your carry-on .
Can I bring a laptop power bank on an airplane?
You are allowed to carry a portable battery that's rated below 100 watthours (Wh) in your carry-on luggage. No batteries are allowed in your checked luggage. Most laptop power banks are rated below 100Wh so they meet the TSA's requirements . Some airlines have enacted rules around the use of power banks. For example, some require that you keep the power bank out of your bag and visible while it's in use. This is to prevent (and quickly catch) fires that sometimes happen when lithium ion batteries overheat.
How many ports should a laptop power bank have?
Three or four is a good number, because then you can charge a laptop and your phone at the same time if needed. Just note that the more things you plug into a power bank, the slower it will recharge everything.
Also make sure the bank has the right type of ports for your needs. Most laptop power banks will have at least one high-powered USB-C port, with wattage in the 60 to 100 watt range. That's the one you'll use for your laptop. Lower wattage USB-C ports and USB-A ports can be used for your phone and accessories like headphones. Just remember that the cable you use has to be capable of delivering the wattage listed on the port, or it'll slow down your charging speeds.
Do laptop power banks have wireless charging?
Some do! In addition to ports for cables, some laptop power banks have a wireless pad up top that can also charge your phone (as long as your phone supports wireless charging). Of course, this feature will increase the price, so only get it if you think you'll need it. Just remember that wireless charging is less efficient than wired charging. To get the most from your power bank's capacity, go with a wired connection.
How much do laptop power banks weigh?
Because of their higher capacity, many laptop power banks weigh between 1.5 to 2 pounds. That may add some significant weight to your backpack or luggage, so make sure to look at a portable battery's listed weight before you buy.
