I would like to have the option to limit the charging to 80%. When I’m not using it that I can keep it in the charger and use it as a charger for other gadgets. But keep the battery life at it’s best as it’s not pegged to 100% for long periods.

Great product. Easy to use with a nice app. Good price!

I was hesitant whether to choose the AC or DC version. The AC version however is significantly bigger, so I bought this smaller DC version which is really beautiful on our living room table.
This DC version is relatively cheap if you already have a USB-C >60W Fastcharger. If not, it can get expensive.
As I like to keep charging times to a minimum, I bought two Anker Prime 100W USB-C Fastchargers and two Ugreen 240W USB-C cables. That was another 130€.
This combo makes it obviously more expensive, so keep that in mind.
I also happen to have an old 24V-5A AC-DC charger for which I bought an XT60 adapter.
I have connected both 100W USB-C into the two USB-C Input ports AND the AC-DC charger into the XT60 port and I was rewarded with a total of 272W input charging power :-)
Note that when SoC reaches 85%, one of the two USB-C charging ports is shut off in order to protect the battery.

In summary, everything works as advertised incl. the App.
As some functionalities are hidden in the App, installation of it is nearly a must, especially for firmware update improvements. However, I find the Android app rather intrusive from a data privacy point of view. Hence I installed the app on my old Android smartphone which uses a Google dummy account.
Once firmware updated and other settings in the app adjusted, you won't have to use it again, at least for another year (to check for new firmware).
Overall, I'm pretty chuffed with my new, portable power cube.

I worried on its size, but to my surprise it is a bit smaller than I expected. Perfect engineering. Very good product, absolutely recommended.

It's really cool and I like it but I got it with twisted handle, stripe was twisted one time.
So when it was stationary it was perfect tool. But now when O need to move with it... It's soo frustrating, because it's a sipliest to do, it's not electronic or roxket science.
Probably there are some videos how to fix it?
