I bought it on the basis of some youtube review where a guy described its high efficiency and low price. Low price in this category certainly agrees, efficiency is hard to judge - I charged it 83.7Wh, I stuffed 62.5Wh into the laptop at 20V charging (i.e. 74% efficiency across charging and discharging). I have not yet measured the efficiency of charging the phone with lower voltage.
It contains two "non-standard" 10Ah flat cells, we will see how it will be with the lifetime.
It charges at 20W ([email protected]), i.e. it charges in about 4 hours.
I also charge my laptop (dell latitude), but I don't charge it with 33W but "only" 28W. ([email protected]).
When charging 20V quite warm around the outlet
The integrated cable is quite impractical, I'm afraid that it will break or break off in the backpack between the other stacks
Only 4 integrated LEDs to indicate the status (but even if other power banks have an integrated display, it still often shows nonsense)
Subjectively I find it unbalanced in weight, but that's a small thing
The integrated cable is short, charging the laptop on the road is a bit awkward through it
