Best 100W Power Delivery Power Banks Mighty Gadget

Any links to online stores should be assumed to be affiliates. The company or PR agency provides all or most review samples. They have no control over my content, and I provide my honest opinion.

Following on from the guide of the best 60W+ PD power banks that are ideal for the Nintendo Switch, Steam Deck and lightweight laptops.

This guide looks at power delivery power banks that are capable of 100W or higher. These tend to have a price premium, which is understandable as they are higher specced. With 100W power delivery, you have a wider range of devices that can be powered with these power banks.

Device Compatibility

The main devices that will benefit from these will be laptops. The 16‑inch MacBook Pro (2021) uses a 140W USB-C power adaptor, and most gaming laptops will now support 100W power delivery.

For gaming laptops, 100W should be enough to run the laptop under light loads. For gaming, they will draw considerably more than 100W, and the laptop will discharge faster than it is charging unless you use the higher-powered DC power pack.

Similarly, with the MacBook Pro, under heavy load, it will likely pull more than 100W, but most of the time, it should be well under this.

Maximum Capacity Power Bank for Air Travel

Most of the below recommendations are high-capacity power banks. They are designed to be used for high-powered devices such as laptops, and small and light power banks won’t hold enough capacity to extend a laptop battery by much.

Many people take their power banks with them when travelling (it is what they are best for), so you should be aware that there are limitations on what you can take on a flight.

For a start, you are not supposed to put any power banks in your checked luggage.

For your carry-on luggage, the limit is supposed to be 100Wh, which normally works out to around 27,000mAh.

Advertised Capacity vs True Expected Capacity vs Real World Performance and USB Cable Efficiency

One common problem with power banks is that every manufacturer lists a relatively misleading capacity of the battery.

The actual capacity should technically be true, but the stated capacity is that of the internal battery, which is normally 3.7 volts. However, most electronics use 5 V or higher.

USB-C power delivery uses 5 V, 9 V, 15 V, or 20 V with a maximum current of 5A

This means the true expected capacity of the power bank will be considerably lower than the quoted figure.

To work out the true expected capacity, you have to use the following formula:

True Expected Capacity = Internal Battery Volts x Stated Capacity / Output Voltage x USB Cable Efficiency

USB cable efficiency is normally around 0.8 to 0.9.

If we take an example of 27000mAh, which is the approximate capacity of many of my suggestions, you get:

  • 3.7v x 27000 / 5 v = 19980 mAh capacity before USB inefficiencies
  • 19980 mAh x 0.85 (guessed average for USB-C)  = 16983mAh true expected capacity

100W Compatible USB-C Cables

Another thing you should be aware of with these power banks is the USB-C cable you use. Gone are the days you could use any old cheap USB cable.

If you want to achieve 100W power delivery, you need a cable that is rated for this capacity. I have used random good-quality cables before, and the charge gets limited.

There is a premium to pay over cheap cables, but they are still affordable:

Some of my suggestions have a USB-C cable included, and I have tried to list this where possible.

Best 100W Power Delivery Power Banks for MacBook, Gaming Laptops, and Steam Deck

Anker 737 Power Bank

Anker 737 Power Bank mightygadget
  • Power Delivery: 140W
  • Capacity: 24,000 mAh
  • Power Outputs: 140W total
    • USB C1/C2: 140W
    • USB-A: 18W
  • Charge Speed: 140W
  • USB-C Cable Included: 140W USB-C to USB-C cable
  • Weight: 1.39 lb / 630g
  • RRP: £140

To the best of my knowledge, the Anker 737 Power Bank is the only power bank on the market that can do 140W output, which is enough to power the 16‑inch MacBook Pro without the risk of it discharging faster than you charge.

Anker claims this will charge an iPhone 13 almost 5 times or a 2021 iPad Pro 12.9″ 1.3 times. It can then charge the 16‑inch MacBook Pro to 50% in just 40 minutes.

The is rated at 86.4Wh, which meets the requirements to be taken on airplanes as carry-on baggage for flights. In comparison, the 16‑inch MacBook Pro is rated as 100Wh.

Zendure Power Bank Portable Laptop Charger

Zendure Power Bank Portable Laptop Charger
  • Power Delivery: 100W (138W max total)
  • Capacity: 26,800mAh / 96.16Wh (17,000mAh (5V ==3A) or 6,700mAh (14.8V))
  • Power Outputs:
    • USB-C1/C2: 100W input/output
    • USB-C3/C4: 20W output
  • Charge Speed: 100W
  • USB-C Cable Included: No
  • Weight: 566g
  • RRP: £230

With the launch of the Anker 737 Power Bank at almost £90 cheaper, the Zendure looks less appealing, but it is still a well-specced power bank. Unusually it has no USB-A ports, instead, it has four USB-C ports, with two rated for 100W. The maximum output is limited to 138W.

Furthermore, they have a built-in OLED display to provide feedback, and the powerbank has upgradable firmware so you can stay up to date with newer charging protocols when new devices come up.

It is quite a bit lighter than the Anker, and the aluminium housing should make it more durable than the Anker.

There is a more affordable model which has the same capacity, the durable aluminium housing, but changes the ports to USB-C PD (100W + 60W) & dual USB-A then ditches the OLED display for a basic LCD. This is around £190.

Imuto X6G-27200 Laptop Power Bank

  • Power Delivery: 100W (Total output 138W max)
  • Capacity: 27200mAh
  • Power Outputs: USB C1 100W(Max); USB C2 60W(Max); USB A1 QC3.0 18W(Max); USB A2 15W(Max)
  • Charge Speed: 100W
  • Weight: 610g
  • USB-C Cable Included: 3.3ft 100W USB C to USB C Cable
  • RRP: £100

Moving on to something a bit more affordable. This power bank ticks a lot of boxes, being cheaper than the other two; it also has the best reviews on Amazon (which includes reviews for the more affordable model).

It then has a high capacity while still being OK for flights and can do 100W on one of the USB-C ports.

An alternative option is the Imuto Taurus X4G PD 100W, which has a 20000mAh capacity, weighs 529g and costs just £70

EASYLONGER Laptop Power Bank

  • Power Delivery: 100W (Total output 138W max)
  • Capacity: 26800mAh
  • Power Outputs:
    • USB C1 100W(Max)
    • USB C2 45W(Max)
    • USB A1/A2 3.8V-6.5V/3A, 6.5V-9V/2A, 9-12V/1.5V (18W Max)
  • Charge Speed: 45W
  • Weight: 550g
  • USB-C Cable Included: 100W USB C-C Cable
  • RRP: £80

This is an affordable and well-reviewed power bank. One reviewer has done the maths for a realistically expected capacity:

This power bank true expected capacity = 3.7v x 26800 / 5.2v x 0.85 (0.85 for average USB cable) = 16208 mAh

With their testing, they used an inline meter and achieved between 12000 mAh and 14000 mAh.

Even though the real-life capacity is well under the official number, it is still good value.

Krisdonia 100W USB-C PD 64000mAh Power Bank

  • Power Delivery: 100W
  • Capacity: 64000mAh/236.8Wh
  • Power Outputs:
    • DC 1/2 : 120W Max        
    • USB C1 100W(Max)
    • USB A1/A2 5V/9V/12V 3A support QC 3.0
  • Charge Speed: 60W USB-C
  • Weight: 1.8kg
  • USB-C Cable Included: A 19V 2.2A charger, a USB charging cable, a USB-C charging cable, a Mag-Safe 2 cable, a DC cable and 14 pieces of connector.
  • RRP: £250

With a 64000mAh capacity, this is not designed to be taken on planes. It is more of a niche product as it also has a DC input/output with a selection of DC port adaptors.

The company claims that the Krisdonia PD power bank 64000mAh charges the 2021 14-inch MacBook Pro 2.2 times, MacBook Pro 16” 1.5 times, iPad Pro 12.9” 3.5 times, iPhone 13 Pro Max 9 times, and the Samsung Galaxy S22 Ultra 8 times.

The company also has a smaller 32000mAh power bank which is priced at around £170.

Baseus 100W USB C Portable Laptop Battery

  • Power Delivery: 100W (Total output 138W max)
  • Capacity: 20000mAh
  • Power Outputs:
    • USB C1/C2: 100W(Max)
    • USB A1/A2: 30W
  • Charge Speed: 65W USB-C
  • Weight: 1.8kg
  • USB-C Cable Included: USB-C to C fast charging cable
  • RRP: £90

Baseus popped up in my last power delivery recommendation post.

Baseus claims this 20000mAh battery pack is tested for charging a drained iPhone 13 Pro Max to 100% up to 2.5 times, 3.4 times for the Galaxy S20 and 0.8 times for the MacBook Pro 13-inch.

One reviewer claims the rated capacity on the battery is listed as 12000mAh on the side of the power bank itself. It could be that they mean actual capacity; using my calculations above, this would work out as 12580 mAh.

This has a handy voltage/current display, which will let you know how fast a device is charging, and it looks like it will show you how long is left before the battery pack is fully discharged.

Overall

If you can justify the cost, then the Anker 737 Power Bank is the option I’d go for. They are by far the most reputable brand in the business, and this power bank has the most powerful PD output on the market.

However, the Anker 737 Power Bank costs 40% more than the Imuto X6G-27200 and double the price of the more affordable Imuto X4G-100W. If you are looking for the best value for money, I’d go with Imuto.
