Ugreen 145W 25000mAh Power Bank Review scaled

I have become a bit obsessed with power banks recently. In particular, power banks that provide high-wattage power delivery. With 60W or higher power banks, it opens up the number of devices you can charge.

Most of my ultraportable laptops are 60W, but things like the 16‑inch MacBook Pro (2021) use a 140W USB-C. Most gaming laptops nowadays support 100W power delivery as well, though that may not be enough power when playing games.

This led me to write up a best of guides for the best 100W+ power delivery power banks and the best 60W+ power banks.

For 100W, the number of choices is quite poor. The Anker 737 Power Bank has been the best option by far, but the competition is improving, and this Ugreen 145W 25000mAh power bank is the best competitor yet.

Compatibility – Does not support the PPS protocol

Ugreen state this has a wide range of compatibility and this supports the PD 3.0 fast charging protocol. Most things that accept power delivery should work but you may need to check the voltage/amp configurations above.

Ugreen list a wide range of Samsung phones as being compatible, and this can sometimes be one area where power banks fall short due to the PPS support.

Ugreen says this is compatible with:

Galaxy S23 Ultra, S23+, S23, S22, S22 Ultra, S22+, S21 FE, S21 Ultra, S20, S20FE, S10, S9, S8+, S8; Tab A8, S8, S7+; Z Flip; Note 10, Note 9, A72, A71, A51, A52, A53, A50, A40, A21, A20; M43, Galaxy Fold 2 etc.

However, Ugreen has confirmed that the power bank does not support the PPS protocol to enable 45W Supercharging on a Galaxy S22 Ultra.

Ugreen 145W 25000mAh Power Bank Review vs Anker 737 Power Bank (PowerCore 24K)

There are only a few good 100W power delivery power banks, and the Anker 737 Bower Bank is probably the best choice on the market.

The Anker has a slightly better specification than Ugreen.

  • USB C1
    • Ugreen: 100W
    • Anker: 145W
  • USB C2
    • Ugreen: 45W
    • Anker: 145W
  • USB A
    • Ugreen: 18W
    • Anker:  18W
  • Max Output
    • Ugreen: 145W
    • Anker: 140W
  • Battery / Capacity
    • Ugreen:
      • 88.2 Wh
      • 3.6v
      • 25000mAh
    • Anker:
      • 86.4 Wh
      • 3.6v
      • 24000mAh

Basically, the Anker has a fractionally smaller battery and total output, but it is generally better in every other department.

For Samsung users, several people on Reddit have confirmed that the Anker 737 supports PPS for both 25W and 45W, which is a big selling point.

Personally, I don’t have any devices that need 145W, so there is barely any difference in the output for me.

I like the display on the Anker as it is useful to see how much power a device is pulling, but it may be less useful for normal people. The Anker does charge faster, which is perhaps the only spec I’d see any benefit from.

The Ugreen has a couple of advantages. I prefer the form factor of this power bank, and the flatter design is a bit more friendly for slotting into a bag. It also weighs a bit less. The flatter design and lighter weight could make this a superior choice for anyone that travels a lot.

Advertised Capacity vs True Expected Capacity & Watt Hours

As I covered in my 100W PD power bank guide, the advertised capacity is less than what you will see charging your devices. This is true for all power banks.

Most power banks are created using Li-ion batteries which use a different voltage to USB. The standard voltage of any USB port will be 5V, though this can go up to 20V with power delivery. 

For a 5V output, you would need to recalculate the capacity as:

  • 5V capacity = (Voltage of Battery * Advertised Capacity) / 5V

For Ugreen, the capacity listed on the back of the battery is 24500mAh and therefore, the true capacity is 17640 mAh capacity.

For the Anker 737, its six 4000mAh cells are actually 3.6v (21.6Vdc),

Therefore, for a 5V output on this 24,000mAh battery, you should have a 17280 mAh capacity.

How many charges does the Ugreen power bank hold?

Ugreen has provided some examples of the number of full charges it can provide:

  • Macbook Pro 14”(70wH) – 1.3x
  • Samsung Galaxy S23 Ultra (5000 mAh) – 3x
  • iPhone 14 (3279 mAh) – 5.6x
  • Nintendo Switch (4310mAh) – 4.3x

Testing Real World Capacity

My first simple test was charging the Realme GT NEO 3 from flat. It was just after I received the power bank, and the charge of that was at 50%.

The Realme has a capacity of 4500 mAh, and when it was fully charged, the Ugreen power bank was left with 22% charge. If everything was 100% accurate, the power bank used 4939mAh of its true expected capacity.

With the power bank at full charge, I charged the Zhiyun Fiveray M40 from flat, which has a capacity of 2600mAh.

Testing Power Output and Input

When it came to charging the Ugreen power bank, I used the Ugreen Nexode 140W GaNFast charger, which can easily charge it at the maximum speed.

My USB power meter confirmed that this accepted a 65W input.

For the output, I don’t have many devices that go up to 100W. Out of curiosity, I tested the Anker 737 with this, and the Anker was able to pull 90W from the Ugreen.

Using the power bank to power the 100W Zhiyun Molus X100 LED lights, the power meter showed 89W at 100% power. Switching to the 45W USB-C port, the light was only able to be dialled up to 45%, and the power draw was 44.1W.

Price and Alternative Options

The Ugreen 145W 25000mAh has an RRP of £140, but at the time of writing (22nd of May), it was £89.99. It is consistently under £100, often requiring the on-page discount vouchers.

The Anker 737 Power Bank (PowerCore 24K) is the best alternative. This has the same RRP, and at the time of writing, it is at full price, but it regularly drops to £98.99. Keepa indicates that £98.99 is the lowest price it has ever been.

The imuto Laptop 100W Power bank is £100 and it is technically better, with 100W + 60W PD outputs with 138W max. It also has the benefit of 2x USB-A ports and a claimed 27200mAh (99Wh) capacity. However, there are a few mixed reviews about its performance.


The Ugreen 145W 25000mAh power bank is a superb power bank that I can easily recommend to most people.

It is priced attractively, has a massive capacity, and the power delivery output should be good enough for most demanding devices.

I think the Anker 737 Power Bank is a slightly better power bank. In particular, if you use a Samsung device with Super Fast Charging 2.0 (PPS), then the Anker 737 should be able to provide up to 45W charging.

The Anker also has a higher maximum output, faster charging and a handy smart display. In reality, I doubt those will make much difference to my real-life usage. The faster charging is perhaps the only benefit which may be handy when travelling and needing to charge things as fast as possible during my downtime.

The Ugreen might be preferable for people that travel a lot, the flatter design is more convenient for bags, and the 100g weight difference isn’t insignificant.

Unless you specifically need 45W PPS or 140W PD for a MacBook, I think the differences are small enough that I’d buy whatever is the cheapest at the time, and as I write this, it is the Ugreen.
