Excellent!

This power bank is a lifesaver! It charges my devices multiple times and is perfect for long trips.

The coolest power bank I've ever seen

I can really see the inside wires through the transparent case. Really cool!! and it charges really fast. The most interesting part is the two charging cables inside. They're so thick like electric wires! Recomend to those who need fast-charging and large capacity power banks.

saved my for work and play.

so this thing is pretty cool as I lost power in my home a few days after receiving it.
it charged my laptop and helped me get through a day of zoom meetings.
One thing I don't like is its cable. Once I plug the USB-A port, it blocks the USB-C port. I can live with that because I have other cables to use.

Happy with Cool Gadget laptop power bank

I received this large capacity power bank for laptop a day earlier than expected. I received it in the middle of a 3 day power outage. Very happy with it! I could tell that it would be a quality charger from the minute I opened it. It supports 22.5W fast charging for my Android and it can charge my phone almost 3 times. Very useful.

FAQ

Is this compatible with the new iPhone 15?
Absolutely! It's compatible with the new iPhone 15 lineup.
Is it worth getting a portable charger?
For most modern people, the answer has to be Yes. Not having a charged cell phone could be life-threatening. You divide the expected battery life by two, and your phone battery still doesn't last that long. Phones are getting slimmer, but they are also getting more powerful. And power requires energy. The energy that phones don't have, but portable chargers do. The Large-capacity Power Bank 20000mAh can be a great choice for you.
What is the difference between a power bank and a portable charger?
There is no difference between a power bank and a portable charger. Both names can be used to refer to the exact same battery pack you use to charge a device. A power bank has several nicknames, including a battery pack.
How many mAh should a good power bank have?
The best capacity for a power bank depends on your needs. For regular phone use or a daily commute, take a look at power banks between 3,000-5,000 mAh, which are portable and have adequate juice. For phone users with unique needs or for particular scenarios, 7,000-10,000 mAh are good options. The Large-capacity Power Bank 20000mAh can be used for a long trip. It can charge your laptop as well, which a small-capacity portable charger can not do.
