Capacity is as advertised, for the most part
Update: after about using it for a month somewhat regularly (maybe 4 full discharges every week or so), the capacity seems to have become somewhat finicky. Now a full charge from 0% to 100% is reading as a transfer of 137 Wh, a full 11Wh decrease within one month. However, even though it reads 100%, it will still trickle charge a bit further if I unplug and plug it back in, leading me to believe that the capacity estimator is not particularly reliable and that the true capacity might not have changed as much. Besides this, I overall still feel like I get the same life out of it in daily use. Still highly recommend for laptops up to 65W.Don't pay attention to the other reviewers saying that the mAh is incorrect. mAh is voltage dependent, so if it's charging at a voltage higher than the voltage of the individual cells within the power bank, it's going to result in a lower mAh readout for an equivalent energy output (Wh). The rated 148 Wh is pretty much on point for mine (charged from 0 to 100). Charging and discharging rates are also as advertised, capable of maintaining constant 20V transfer and up to a peak rate of 50-60W as far as I've seen. I just received it, so I can't comment on longevity yet.

No GO
Hatte diese Powerbank insgesammt 2 mal bekommen.... jedes mal war sie defekt. Hat anfangs immer geladen und sobald sie einen bestimmten entladezustand angenommen hatte, brach alles zusammen. Der Verkäufer wälzte zuerst alle schuld nur auf mich, und das ich der einzigste Kunde damit sei. Nachdem er sie aber selbst geprüft hat, versicherte man mir das ich eine Funktionierende bekomme, was leider nicht passierte. Diese war genauso defekt.Service schleppend,Produkt mangelhaft,Verkäufer keine Hilfe leider......

これよりお得なモバイルバッテリーいないぜ
だが、もうモバイルバッテリーとは呼べない重さです。😅

It's good for about a year.
This item worked great for about a year. Now I can charge my S22 Ultra 3 times and when the % is at about 35 ... It goes dead.

本当に大容量
充放電を何度か繰り返して測定したところ、120Wh程度の測定値であり、40Ah（148Wh）の容量に嘘は無いと思われる。大きくて重いのは当たり前で、こんなに大容量が5,000円弱（20%クーポン使用）で手に入るのは正直驚きであった。また、65W出力も本当で、20V、3A程度でノートパソコンに充電出来る。謳っている性能に偽りなしで、大きくて重くても良いなら買って損はない。
