The Anker Prime 26K Power Bank (300W) is one of the most powerful laptop power banks that you can match with your MacBook. It is a great fit with the top-end 16-inch MacBook Pro, which has a battery rated at around the same watt hours (99.6WH) as this power bank (99.75Wh).

There are three USB ports. Each of the two USB-C ports can be used to power at 140W. Attach Apple’s USB-C to MagSafe 3 Cable or the included 240W USB-C cable to the power back and you can utilize one of the 140W PD 3.1 ports to fast-charge the 16-inch Pro. Indeed, with its 300W total output at your disposal you could fast-charge two of the top-end MacBooks at the same time and still have enough juice to fast-charge your iPhone!

Anker claims that you can fast-charge that top-end MacBook Pro up to 50% in 27 minutes. In our tests, we charged a 14-inch M2 MacBook Pro to full power with enough left over to power it back to 25% on the second recharge.

You can recharge the power bank itself to 50% in under 150 minutes using the two USB-C ports at the same time at an impressive 250W.

This is a sophisticated power bank with some tricks of its own. It can be controlled by an app, which gives real-time charging stats (Remaining Charging Time and Input and Output power indicators) and can be optimized to help extend the battery life of the devices being charged as well as its own. You can even use the app’s Find Device feature to activate a sound alert from the power bank when you need to locate it.

Anker also sells a 27K Prime Power Bank, available in either black or gold colors. We prefer the 26K model as it’s a little smaller, performed better in our tests, and out guns the 27K model in total output (300W vs 250W) and input (250W vs 170W).

Who should buy the Anker Prime 26K 300W Power Bank?

Powerful enough to charge two 16-inch MacBooks at the same time, this power bank is a great travelling companion for any of Apple’s laptops. Both its 300W total output and 250W input are top-end for a truly portable power bank.

Although a little larger and heavier than the Anker Prime 26K 300W Power Bank, reviewed above, the EcoFlow RAPID Pro 27K Power Bank (300W) has a hidden weapon in its battle for the best MacBook power bank: a built-in retractable USB-C cable tucked away in its base—saving you from carrying a spare cable around with you and keeping your travel bag neat and tidy.

Like the Anker Prime 26K, this power bank can fast-charge two 16-inch MacBook Pros at full pelt. It boasts the same 200W total output, and has two more USB-C ports—both at a potential 65W—but no legacy USB-A port. If you need a USB-A port, look to the Anker Prime instead. USB-A aside, it can recharge up to four devices at the same time, although. With three devices it can output at 140W, 95W and 65W—enough for three MacBooks at the same time. And using all four charging points, still allows for two MacBooks at 140W. with the remaining two USB-C ports sharing 20W.

In our tests it scored 120%—a little lower than the Anker Prime’s 125% but nothing substantial in comparison. It can be recharged itself at 280W, which is a little faster than its Anker rival.

Who should buy the EcoFlow RAPID Pro 27K 300W Power Bank?

As powerful as the Anker Prime 26K Power Bank and boasting a built-in USB-C cable plus an extra port, the EcoFlow RAPID Pro is a real rival for the crown. If you can take the (minimal) extra weight and don’t need a USB-A port, it is highly recommended if only for the retractable cable.

The Ugreen 48000mAh 300W Portable Power Bank is the missing link between a laptop power bank and a full-blown power station. It has a huge battery capacity but is still portable, although you wouldn’t want to carry it around in your backpack all day, and it’s too powerful to take on a commercial flight.

It has a handle so is carriable, but the bulk and weight mean it is one to move around inside or carry in a car. It would be the perfect power companion on a camping trip. It’s not super-heavy, but it is noticeably larger than the other laptop power banks tested here.

Keep it powered up in case of power outages and it should keep your laptop and phone going for days. In our tests we recharged a 14-inch M2 MacBook Pro 1.8 times, so you can expect to get maybe as many as two charges for a MacBook Air. The Pro charged from 5% to 90% in an hour, which impressed us.

There are five ports (three USB-C and two USB-A) with a maximum simultaneous power output of 300W. As it has a 140W PD 3.1 USB-C port, it can be used to fast charge a 16-inch MacBook Pro. At the same time, you could charge another top-end MacBook Pro at 100W, and use one of the USB-A ports at 22.5W.

The smart display shows the remaining battery, total input and output power.

Who should buy the Ugreen 48000mAh Portable Power Bank (300W)?

Portable but certainly not pocketable, this is the border between power banks and power stations and would be a great travel gadget if you have a vehicle to carry it in. It is also a mini-prepper’s safeguard against power outages at home.

Retractable cables are very in right now—although nicely tucked away when not in use—for power banks and chargers. This 20K Ugreen Nexode Power Bank has one 2.1-foot retractable 100W USB-C cable nestled and ready for action right next to another 100W USB-C port and a 33W USB-A port.

At under 19oz it’s a little lighter than the cable-friendly Anker 25K 165W power bank, reviewed below, and is half an inch shorter, too. Although it matches the Anker on 165W maximum power output and 100W ports it does have a smaller battery capacity—although is therefore $20 cheaper. In our tests the 25K Anker recharged a 14-inch MacBook Pro to 92% while this 20K Ugreen power bank reached a respectable 78%.

In the battle for power and cable convenience, these two power banks must be chosen on capacity, portability and price.

Who should buy the Ugreen Nexode 20K 165W Power Bank?

This mid-range laptop power bank is compact and lightweight with a handy retractable cable, and will get your MacBook back up to about three-quarters power on a single recharge.

Ugreen

Ugreen sells another 20K model with a built-in USB-C charging cable. The $79 Nexode Power Bank 20000mAh 130W (above) is shorter at 5.1 x 2.1 x 1.9 inches (12.9 x 5.3 x 4.8cm) and $20 cheaper with the same 20K capacity but a lower max power output of 130W vs 165W. It weighs fractionally less than the 165W Nexode. Buy the 130W model if all you need is to charge a MacBook at 100W and an iPhone at 30W—this stubbier cousin may be all you need. It’s integrated 5.4-inch USB-C cable—useful for MacBooks and later iPhones—is nowhere near as long as the 165W model’s 2.1ft retractable cable but it can double up as a carry handle.

Buy the 165W model if you regularly charge two laptops at the same time: one at 100W and the other at 65W. On both 20K models, the USB-A output can be handy for legacy devices.

Macworld Test Score: 92%

The performance is impressive—we recharged a 14-inch M2 MacBook Pro to a respectable 92%, not far off the 100% from its slightly higher-capacity sibling Anker 27650mAh power bank—but what we love about this laptop battery pack is its handy 2.3-foot (70cm) retractable USB-C cable that means you don’t have to carry one with you when you take the power bank walkies. There’s even a second built-in USB-C cable that doubles up as a carrying loop.

Each USB-C port can output and provide input at 100W.

The cable wraps neatly into a groove at the top of the power bank. There’s spare USB-C and USB-A ports on one side, so you can charge multiple devices simultaneously. Note that if you want to charge more than one device, they must share the maximum output of 165W between them. However, 165W can only be supplied by two devices; with three and four devices, the maximum output is limited to 133W, although that is likely enough for most needs.

It’s available in either Space Black or Silver.

With its integrated cables this is one of the the most travel friendly laptop power bank we’ve tested.

A cheaper alternative is the 65W Baseus Free2Pull Power Bank that features one retractable USB-C cable, which is available in the U.S. at Amazon or in the U.K. via AliExpress.

If you frequently recharge multiple devices at the same time, maybe one integrated USB-C cable won’t be enough for you. This power bank boasts two cables, and performed well in our tests.

The INIU P62-E1 20000mAh (65W) Power Bank may have a dull name but it stands out a mile with its colorful looks—it’s available in six bold colors—and dare-to-be-different compact shape.

Not just fun to look at and easy to hold, it performed excellently in our tests, recharging a 14-inch MacBook Pro to 87% from a flat start, outperforming our recommended 20K power bank, the Ugreen Nexode 20000mAh Power Bank, reviewed higher up, by nearly 10%. That Ugreen power bank features an integrated retractable USB-C cable and is more powerful with 100W outputs and a maximum 165W power—beating the 65W INIU.

The INIU P62-E1 might not have a retractable cable but it does boast a removable USB-C cable that creates a handy carrying loop.

While 65W is a little lacking—but not unusable—for the Pro MacBooks it’s ample for the MacBook Air.

Who should buy the INIU Cougar 20K (65W) Power Bank?

Stand out from the crowd with this cute and compact laptop power bank that offers impressive performance for MacBooks that don’t require top-end power output to fast charge. That said, even MacBook Pro owners may desire something as lovely as the Cougar.

The Anker Prime 20K Power Bank is a recommended laptop power bank that is lighter and smaller than the top-end Anker Prime 27650mAh Power Bank, but boasts the same number of USB ports.

Anker has a couple of 20K laptop power banks that are worth considering. The latest model is the 3-port Anker Prime 20K Power Bank (220W), which boasts two 140W PD 3.1 fast-charging USB-C ports and a 22.5W USB-A. When charging with all three ports at the same time, it offers two 100W outputs and a 20W. With two it can output two USB-C at 110W or one at 140W and the USB-A at 22.5W.

The older but slightly cheaper Anker Prime 20K Power Bank (200W) doesn’t feature the 140W PD 3.1 USB-C ports, instead packing two 100W USB-C ports and a generous 65W USB-A port. That doesn’t rule it out as a battery pack for the 16-inch MacBook Pro, but it can’t fast-charge Apple’s largest laptop. Its maximum output of 200W is a little below the 220W model.

Both feature a clear display but only the 220W model works with the Anker app. While the 27650mAh Anker Prime can be charged itself at 200W, the two Anker 20K Power Banks can be charged at a lower, but still reasonable, 100W using just one of its USB-C ports.

The 200W model is noticeably shorter than the 220W, measuring 4.9 x 2.1 x 2 inches (12.7 x 5.5 x 5cm) compared to the 220W’s 5.8 x 2 x 1.7 inches (4.4 x 5.0 x 14.7cm), although the 220W is a little lighter at 1.1lbs (510g) compared to the 200W’s 1.17lbs (529g).

The 200W model is cheaper at $139 compared to the 220W model’s $179 price tag, but both appear quite expensive when compared to some rival 20K power banks; see the Ugreen 20K Power Bank reviewed below. The 200W model fared impressively in our recharge test.

Who should buy the Anker Prime 20K Power Bank (220W or 200W)?

Although priced at a premium, these are great options for the smaller MacBooks unless you need as much power in the bank as you can carry. If you don’t need the 140W outputs, the 200W model will save you some cash, or consider the lower-output Ugreen Nexode 20K Power Bank below..

Great for: 14-inch MacBook Pro, 13-inch or 15-inch MacBook Air.

Thomas Bergbold

Ugreen’s equivalent to the Anker Prime 20K Power Banks is the much cheaper $89 Nexode Power Bank 20000mAh, pictured above. The battery capacities of both are identical, but the Ugreen is noticeably lighter (1lb or 480g) even though its dimensions are closely aligned: 5.1 x 2.1 x 2.0 inches (13.1 x 5.4 x 5.1cm). Each has a smart display that tells you more than enough about what’s going on between the power bank and the devices being charged.

The Ugreen Nexode is a more portable solution, but we still prefer the Anker Prime model for both its impressive USB ports. The Anker has two 100W USB-C ports, while the Ugreen’s USB-C ports are rated at 100W and 30W. As the Ugreen power bank has a maximum power output of 130W, this doesn’t matter, but the Anker can pump out up to 220W simultaneously, making its powerful ports more useful. Power input is also better on the Anker (100W) vs the Ugreen (65W).

However, we’ve seen the Nexode Power Bank 20000mAh priced a lot more competitively than the Anker Prime 20K, and that weight difference may be important to you. Also, for the lone traveller one port for the MacBook and another for fast-charging an iPhone or iPad might be all that’s required. Read our full Ugreen Nexode Power Bank 20000mAh 130W review.

The Cuktech 15 laptop power bank we tested might not perform to the same degree as more expensive rivals but offers great value for money.

Despite its somewhat confusing name, the Cuktech 15 has a 20K (20000mAh) battery that managed to charge our test 14-inch M2 MacBook Pro to 60% power. That’s not as impressive as other 20K power banks reviewed here but at under $50/£50 it’s one of the cheapest MacBook battery pack that we trust.

You can use it as a multiple-charge iPhone power bank, too: it should charge an iPhone 15 around 3.5 times. You double-click the power button to enter low-power mode for devices such as a smartwatch or headphones.

With the three USB ports all in action, you can charge the MacBook at 65W and share the remaining 20W between the other USB-C and USB-A ports.

The Baseus EnerCore CR11 even sounds like a battery name and maybe power banks are becoming as ubiquitous. This handy-sized 20K battery pack is the lightest one we have tested and includes a retractable 27.6-inch (70cm) USB-C cable that tucks away at the top when not is use.

In our tests it recharged an 14-inch M2 MacBook Pro from 0% to 95%, which is excellent going for such a compact power bank.

It is probably best suited to the MacBook Air as its power output is 67W, which is just enough to fast-charge one of Apple’s entry-level laptops. It will work fine with the Pro models—as proved by the tests mentioned above—but will be a slower charge. At a total output of 67W and 45W input (charging the power bank itself) the EnerCore CR11 looks a little weak in comparison to some of its 20K rivals.

That said, it’s lightweight and compact with a simple remaining-charge display, and won’t weigh down your hand luggage as much as the others.

A little cheaper than the higher-capacity Cuktech 20, reviewed below, this slim laptop power bank can also fast-charge even the 16-inch MacBook Pro with its 140W output. The 20 looks the better buy in terms of capacity and at a similar price, but the 15 Ultra has a special feature known as Beast Mode.

While the 25000mAh battery of the Cuktech 20 is certainly worth the small extra investment on this 15 Ultra in terms of capacity, this 20000mAh power bank impresses with its super-speedy 165W input, which means you can recharge itself faster than most using Beast Mode where you use both the USB-C ports to recharge the power bank up to 70% in around 20 minutes.

The smart display shows you what each of the ports is doing, battery status, connected devices, and when the unit is powering up in Beast Mode.

Outdoor adventurers and in-the-field professionals need devices that are stronger than softy office desk jockeys and occasional airport travelers, and the Sandberg Survivor boasts a tough !P66 shell that is impervious to water and dust. As such it is bigger than most power banks but it would survive outdoors much longer and has a big enough battery to keep a bunch of devices charged up before being introduced to a wall charger again.

Behind a protective rubber flap there are three USB ports: two old-school USB-A and one USB-C. We would have preferred more USB-C, which is used on most modern devices, and that singular USB-C port is also where you will charge the power bank itself. The USB-C port outputs at up to 65W and receives power at 60W. Each of the USB-A ports can output at 18W. Total simultaneous power output is 65W. Uniquely, there is also a 24W DC 5525 port if your devices can be powered using this connection.

As it charges at a maximum 65W, it’s better suited to the lower-end 14-inch MacBook Pro and 13 and 15-inch MacBook Air, rather than the more powerful versions of the 14- and 16-inch Pro MacBooks that prefer a 100W or higher charger. That said, if your 16-inch Pro is on an outdoors adventure, the Survivor will still charge it, just a little slower than a 100W or 140W power bank.

Built for travel, this combo 4-in-1 wall charger and 10K battery pack can charge a laptop at 45W as a power bank and at 65W when plugged directly into a wall power socket. It comes with international plug adapters for U.K., E.U. and AU/NZ that slip onto the built-in U.S. foldable prongs—great for travel or just use in your own region. It even has a fold-out rubber handle that you can use to attach it to your backpack while hiking.

Its 10000mAh battery capacity is certainly not the highest of the laptop power banks we have reviewed here, but it did recharge a completely faded 14-inch M2 MacBook Pro back up to 45%, which should get you an extra few hours charge when on the move, depending on your laptop’s battery health.

Its two USB-C and one USB-A ports make it a capable AC wall charger, and a magnetic side pad works as a 15W Qi2 wireless charger for the MagSafe-ready iPhone 12 to 16 families. If charging by wall, the USB-C port output is 65W. When operating as a power bank, the USB-C port outputs 45W, unless also wireless charging when the maximum out put is 30W (15W wireless plus 15W USB-C).

A smart displays shows the power bank’s remaining battery charge, remaining time to full charge, real time output/input, and temperature.

While certainly portable it isn’t one to slip in your pocket or clamp to your phone on the move—the Nexode Qi2 is aimed at the iPhone using laptop owner. It’s a handy travel companion that should handle most of your power bank needs while out and about, and then sit on a desk as a smart-looking and informative charger that can charge four devices simultaneously.

The Cuktech 20 Power Bank 25000mAh 140W PD 3.1 power bank looks a lot like the Anker Prime 27650mAh, reviewed above, in a tall format with an informative smart display.

As with the Anker, there are three USB ports, with one at the required 140W for fast-charging a 16-inch MacBook Pro. The other two ports aren’t as powerful as the Anker’s though: 45W vs 140W, and 30W vs 65W.

An M2 MacBook Air should be fully charged with a little power left over for your iPhone, AirPods or Apple Watch.

Power input is also not as great, but at 110W it’s impressive enough compared to most. Maximum simultaneous power output is 210W—again not as high as the Anker but still respectable.

The Cuktech’s display gives more data than the Anker, which is informative for wattage junkies but probably overkill for most of us, who just need to know how much battery life remains in the power bank. Anker’s dedicated app is perhaps more useful. Again, this is a nice to have and the Cuktech power bank does the important stuff of recharging the laptop at a price point that is noticeably lower than Anker’s.

Who should buy the Cuktech 20 Power Bank?

This is an affordable 140W-capable power bank that lacks some of its rivals’ top-end specs but might be all you require at that price.

Great for: 16-inch MacBook Pro.

The Cuktech CP253L is a budget rival to the Anker 165W Power Bank and Baseus Free2Pull Power Bank, and indeed any of the 20K laptop power banks reviewed here. It wins points for its built-in USB-C cable, although at 6 inches (15cm) the cable not as long or handy as the 2.3-foot (70cm) retractable cable on the Baseus.

It is also a less powerful: 45W vs 60W via USB-C, and charges itself slower, too. It recharged our test MacBook Pro to 75%, again a little off the Baseus performance but probably enough for most users in need of a power boost. At 45W it’s fine for the MacBook Air but a little underpowered for the Pro MacBooks, which will charge a little slower.

(We’re only interested in Apple’s MacBook here but if you also own a Xiaomi laptop, its USB-C connectors can charge at 55W and the USB-A supports 33W UFCS charging for some Chinese phones.)

Who should buy the Cuktech CP253L 20K Power Bank?

The lower power input and output plus shorter cable, along with a slightly heavier weight, are compromises you may well overlook when you see the price. This is a great-looking—in either black or a cool white—and solidly performing portable battery pack for your laptop. It’s also available in the U.K. unlike the Baseus.

Great for: 13-inch or 15-inch MacBook Air.

Battery capacity: 97.2Wh
Fastest Power Output: 140W

This is another column-shaped laptop power bank with a high-capacity. The three top-mounted USB ports support PD 3.1 so it is particularly useful for owners of the 16-inch MacBook Pro, which can be fast-charged using one of this power bank’s 140W ports.

As total power output is also 140W, you can’t charge another device at the same time as fast-charging that top-end MacBook. If you want to simultaneously charge more devices, look for a power bank with a higher maximum power output. The similarly designed Anker Prime 27650mAh, reviewed above, can use all three of its ports up to 250W. The Ugreen 48000mAh Portable Power Bank, also reviewed previously, is a larger unit but can reach 300W total power output.

The Alogic Ark has a smart display screen that shows you how fast devices are charging, remaining battery capacity, and how long it will keep charging at the current speed.

Who should buy the Alogic Ark 27K Power Bank?

It’s a well-priced laptop power bank so you might be happy to choose the Ark over an alternative that can pump out more power at one time.

The Baseus Blade HD Laptop 20000mAh Power Bank is a different design to most other laptop power banks. It is slim (1.8cm) and almost square rather than a rectangular obelisk. This makes it easier to slip into the laptop compartment of a backpack or case.

There are four ports: two 100W USB-C, and two 30W USB-A.

The 20000mAh capacity is enough to charge a 13-inch MacBook Air from zero to 100% once, with about 5% remaining.

The Blade HD also recharges via either of the two USB-C ports—although at 65W it’s slower than others reviewed here. In our tests it reached 90% after just 90 minutes and is fully charged after just under two hours—batteries always take longer to fill the last part of the charge.

Like other laptop power banks, it features a smart display, but this one is harder to read than the others tested here. It provides information about the capacity percentage, voltage, and current, as well as the approximate time for the charging process, but the practical benefit of the display would be even greater if the power was displayed in watts and not in a combination of volts and amps.

Baseus makes good products but can be let down by a confused product lineup. As well as the “Blade HD“, there is also a “Blade” with very similar specs and price but slightly longer (6.4 vs 5.3 inches). As far as we can tell, only the Blade is available in the U.K. while the smaller Blade HD is available in the U.S. and E.U.

Who should buy the Baseus Laptop Powerbank 20K?

If slimness is key in carrying your laptop power bank, the Blade will slip into a backpack or briefcase with ease.

Great for: 14-inch MacBook Pro, 13-inch or 15-inch MacBook Air.

Battery capacity: 90Wh
Fastest Power Output: 140W
Total Power Output: 145W

As well as its oblong Nexode laptop power banks, Ugreen offers an alternative slab shape in the form of the Ugreen 25000mAh Power Bank. We think the slab shape works better for portability, while the more vertical Anker shape looks good when sitting on your desk.

Offering 140W PD 3.1 via one of its USB-C ports, it is ideal for fast-charging the 16-inch MacBook Pro. Maximum power output, however, is only a little over 140W so there’s not much power left if you want to charge another device at the same time.

There’s not enough battery to fully recharge Apple’s top-end MacBook Pro, but it gets very close when recharging our test 14-inch M2 MacBook Pro.

It is closest to the 27650mAh Anker Prime power bank, and while having a little lower battery capacity it is nearly a quarter of the weight so is easier to carry around with you. The Ugreen battery pack can charge the same number of devices (three) as the Anker, but the Anker can pump out 250W of power simultaneously while the Ugreen is limited to 145W. The Anker is also much faster to re-charge itself, with 170W power input compared to Ugreen’s 65W.

The display is not as smart as those on other laptop power banks reviewed here, showing just the remaining percentage. That said, this is the key statistic you’ll be interested in rather than more detail on power input and output wattages.

Who should buy the Ugreen 25K Power Bank (145W)?

The max power output means you’ll only charge one MacBook at a time, but this is a slim portable power bank that offers enough charge for short travels.

Great for: 16-inch MacBook Pro.

Battery capacity: 72Wh
Fastest Power Output: 100W
Total Power Output: 100W
Power Input: 65W
USB ports: 1x USB-C (100W PD 3.0); 1x USB-C (30W); 1x USB-A (22.5W).

As well as its 25000mAh laptop power bank, Ugreen the a smaller and lighter Ugreen 100W 20000mAh Power Bank that is well-suited to the MacBook Air. This power bank should have enough juice in it to fully recharge a 15-inch M2 MacBook Air.

This model has a 100W power output so is less able for the 16-inch MacBook Pro, although it would still offer enough recharge to give even that laptop a few more hours of usage on the road, although with a total 100W, it’s limited to also charging other devices at the same time as a larger laptop.

Who should buy the Ugreen 100W 20K Power Bank?

This one is a useful option when portability is the main aim, as at 419g it’s one of the lightest laptop power banks with a decent battery capacity.

Great for: 14-inch MacBook Pro, 13-inch or 15-inch MacBook Air.
