I've charged everything with it that has USB, from headphones, smart watches, Handsfree, mobile, tablet and laptop.
Powerbank with long endurance which you will appreciate especially during a longer stay in the countryside where you do not have access to an electrical outlet.
A little more weight

The 40000 mAh capacity is at 3.7V, so at 5V charging it has about 29600 mAh. Think about this when choosing.
Large battery capacity
The display shows the current charge of the power bank, voltage and current flowing.
Serviceable port selection
Impossible to charge multiple devices with different voltages, always adjusting to the lowest possible. Tz. it is not possible to charge the laptop + e.g. Watch

The power bank has a very good price/performance ratio, i.e. for little money, it has a large capacity and can also charge the device quite quickly. Some other sources wrote about pass-through support (i.e. simultaneous charging of the PB and the connected device), which we need, so we tried to buy PB. But unfortunately it can't do that and not even a little bit (other PBs can't do full pass-through, but they can at least partially reduce the charging current and it works in limited mode). With this PB, it basically stops charging the PB and almost stops charging the connected device. We eventually had to go back and look elsewhere for PB because of this. Note to fully charge/discharge PB before use: Someone mentioned that it's not necessary. Yes, Li-Pol batteries don't need it. However, this is not to "activate" the battery, but to calibrate the display and display the battery capacity correctly/accurately (otherwise PB will e.g. discharged, even though it will report about 20% of its status; or it doesn't recharge 100%, etc. ).
price for 40 Ah power bank
display showing battery capacity, voltage (V) and charging current (A)
fast charging (12-13h)
powerbank does not support pass-through at all, i.e. simultaneous charging of PB and connected device
large and heavy (slightly larger and heavier than other 40 Ah PBs)

Notice in the box is a paper with instructions that states complete battery discharge and charge. The powerbank has a Li pol battery which does not require this step 👍🏻

in short, well processed and large powerbank that will hold you for a few days.
capacity good, but it has more like 30.000-35.000mah
display
appearance, and processing
charging via usb-c
