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.

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.

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.

If you're looking for a backup battery for your power-hungry USB C devices (such as a Surface Go tablet), then your old USB battery isn't going to work. You'll need a battery like this one.
The battery itself seems solid and it is able to charge my Surface Go and other USB devices pretty quickly. It recharges fast, too. From this perspective, it works well and does what it is designed to do.
I still think it would be better if it shows clearly which port can charge the power bank.
