The product surprised me on delivery by the size. I kind of didn't expect that. The capacity is impressive. It will easily cover the consumption of one iPhone 13 and an Apple Watch on a week's holiday, including recharging the battery lamp. You could probably feed a second iphone. It is recharged via an adapter. Included are a lot of connectors and attachments that I don't use. Includes a travel case, but only for the device itself, with a pocket for one or two cables. The adapter for recharging must travel free. It has a digital indication of how much capacity is left. It'll recharge in a couple of hours. Uses MacbookPro or laptop.

The quality is good, but the battery capacity is definitely not up to par [I see it more like 10-20K mAh]

according to the number of times the tablet is charged, the 40000mAh does not work out, but still a decent capacity overall
huge set of reducers for all possible power inputs
fast charging via transformer
the capacity display is almost a joke and cannot be followed at all

Capacity
Supports fast charging via an adapter to a power outlet
Cannot charge slowly via microUSB
The battery % indication is very inaccurate, at constant load it first hardly drops and then starts dropping very quickly.

Huge capacity and it charges with its own charger, so in 6h it is fully charged.

High capacity
Quality workmanship
Unfortunately it does not have DC-OUT -> USB output, so e.g. Lenovo MiixII, among the 2% of unsupported devices

Works as expected
Super realistic capacity, fast charging from a proper transformer (not from a phone microUSB charger)
Charging the MacBook from 10->100% used about 25% of the power bank capacity. It lasts me realistically for 3 working days without electricity
Display - clear overview of capacity/mode
Good design
Take into account that it weighs 1.2 kg

Solid endurance
Clear display of voltage and remaining capacity
Unlike some other powerbanks, it can't power a device and recharge at the same time
It has adjustable output voltage separately 8,4 V and 9 V, but it doesn't have 15 V (it can do either 12 V or 16 V), which is a problem for a spoiled older Toshiba - it just needs the 15 V
