UGREEN 145w 25000mAh Fast Charging Power Bank Review

Design

As our devices have become larger and more powerful, so have their power requirements. Remember those small “lipstick” power banks? They’re difficult to find now!

The UGREEN 145W 25,000mAh power bank is built for those powerful devices with its large 25000mAh capacity and its ability to output a total of 145 watts. It has some weight to it at just over 1 pound, which is something to keep in mind if you plan to carry this around frequently. It could potentially add some extra heft to your laptop bag! Its dimensions are ‎6.3” x 3.2” x 1.1”. It looks sleek with its matte, silver-colored finish with an LED display on the side to show you the remaining capacity, which is a lot easier to interpret than the 4 blink LEDs many other power banks use.

Performance

Sure, this can charge your smartphone, but where this power bank really shines is its ability to charge your laptop! It can handle MacBooks with a USB-C port including the MacBook Pro and MacBook Air, and other modern USB-C devices such as the Dell XPS 15 and 13, Nintendo Switch, Steam Deck, and more.

This really comes in handy for both students attending class or professionals attending a conference, for example, where you may be moving from class to class (or session to session) and need a portable method to keep your laptop charged. Therefore, you don’t need to try and be the first person in the room to secure a desk by an outlet. And, thankfully, this power bank has 2 USB-C ports and 1 USB-A port, so you can share it with a friend.

It can also charge smaller devices such as iPhones, iPads, and Android phones. It also supports “trickle charging” (by holding down the power button for 3 seconds) to charge even smaller items like AirPods, Apple Watches, and Bluetooth earbuds which would normally draw so little current that most power banks would think they are done and would shut off.

If you have another USB-C device, you’ll want to refer to the “Technical Specifications” below to verify that the power bank is capable of the voltage and amperage that your device needs to charge, just to be safe. However, the UGREEN 145w power bank seems to conform to all modern charging standards, so I have yet to find a device that does not charge with it. Below are some of the devices I tested.

Apple MacBook Air M1

The UGREEN 145W power bank was able to charge my MacBook Air with 20V.

Nintendo Switch

The UGREEN power bank successfully charged my Nintendo Switch at 15V.

Lenovo 14W Laptop

My Lenovo 14W Laptop (running Ubuntu!) was able to charge with its normal 20V profile with this UGREEN power bank.

Dell Chromebook

The UGREEN 145w power bank supports the Dell Chromebook’s 20V charging profile, allowing it to charge at full speed.

Features

• Two USB-C ports: This power bank allows you to charge two USB-C devices at the same time, although, when you’re charging multiple devices at the same time, the maximum wattage gets split up among the available ports. Please refer to the image below to see how the number of ports in use affects each port’s maximum output.

• “Regular” USB-A port: If you have a charging cord with a rectangular USB connector, you can still make use of this power bank as it has a USB-A port in addition to the two USB-C ports.

• Trickle charge mode: By holding down the power button for 3 seconds, you can activate “trickle charge” mode, which allows device that draw very little current (such as AirPods, Apple Watches, and Bluetooth earbuds) to continue to charge even when most power banks would assume they’re done.

• LED Display: The unit displays a numeric readout of the remaining charge capacity.

Recharging the UGREEN 145W power bank

You can recharge the UGREEN 145W power bank by using the either USB-C port, but USB-C port #1 can accept up to a 65W charge for the fastest recharge (USB-C port #2 accepts up to 45W, but only one can be used at a time). For example, you could use UGREEN’s 65W USB-C charger to recharge the power bank in as little as 2 hours.

Additionally, lower-wattage USB-C chargers will work as well, just at a longer recharge time. For example, if you used a tablet charging brick (generally around 18W), it could take 12.5 hours or more to recharge.
