Overall, I am very satisfied with this power bank. I also have its previous generation (it had the same capacity, but USB-C PD only 45W and did not have an area for wireless charging). I have tried some solar panel solutions before, but the problem with them is that the conditions are not always right to use them. This power bank has so much energy that I don' t have to deal with a solar panel. I was particularly interested in its good capacity/weight ratio, which makes it suitable for traveling on foot. With such a large capacity, I was pleased with the new generation' s 60W charging via the supplied adapter, which, since it can also handle other voltages within PD, I often use it for other devices as well. (an advantage for me and a possible disadvantage for others may be that the USB-C cable is attached to the supplied charger). Personally, I am also pleased with the presence of a 12V cigarette socket, which expands my options. It just bothers me a little that it doesn' t maintain a constant voltage and, like a car battery, the voltage decreases during discharge. so if you connect, for example, a portable car cooler, it may not be able to use all the energy and at a certain level of power bank discharge it will stop taking energy. The second and at the same time the last thing that bothers me a bit is the slightly distorted indication of the capacity, 77850mAh is also indicated by the manufacturer, so Alza is innocent in this case, but the numbers do not match. The battery has 24Ah at 11.1V (probably 3 lithium cells 3.7V in series), but this capacity corresponds to 72000mAh at 3.7V and not 77850mAh (it wouldn' t fit even at the usual 3.6V). I don' t know how the manufacturer came up with that number. But what, instead of charging your mobile phone 15 times, you only charge it 14 times. for me, the power bank offers so many positives that the two mentioned won' t spoil it for me. In conclusion, maybe just wishful thinking, maybe someone will make a similar powerbank (comparable capacity), which will also have a classic socket on top and will fit under 2kg. This is how I have to prefer a different power bank during some trips, which has generally worse parameters, but unlike this one, it has a classic socket.
