You've to check your notebook's PSU output W.  Many of the Lenovo/HP/Acer/Dell notebooks are using 65W PSU.

How about Smartcoby Trio 67W 2C1A 20000mAh Powerbank?
USB-C output: 5V3A / 9V-3A / 12V-3A / 15V-3A / 20V-3.35A (Max. 67W)

我用緊呢隻, 試過電腦由20%叉上50%就完左, 幫唔到幾多, 應急用下就得

    20000mAH係咁上下, Notebook用65W電, 好快扯乾

mAh 並唔代表容量要知埋電池 cell 嘅電壓
最準確睇電池容量應該睇 Wh
手頭上啲 Anker 電都有寫幾多 Wh

要計 Wh 可以用以下公式
mAh / 1000 * V = Wh
1Ah = 1000mAh

例子
Anker Prime 27,650mAh Power Bank (250W)
27650mAh / 1000 * 3.6V = 99.54Wh

如果 Notebook 充電要求 65W 嘅話要計算頂到幾耐
99.54Wh / 65W = 1.53h ~= 1 小時 31 分鐘
仲要預留返部份電壓轉換嘅損失個時數會再少啲

Smartcoby Trio 67W 20000mAh vs Anker Prime 250W 27,650mAh
330g vs 660g
HK$3xx vs HK$12xx

I'm okay with the highly portable and affordable Smartcoby Trio (or anything similar) for emergency use

Some laptop nowadays have a battery health protection that would stop charing at a set charge level (e.g. 60%), when the laptop battery is not charging, the chaging input would be used to power the laptop directly, thus the charge of the powerbank can last for longer in this situration, therefore keep the powerbank connected to the laptop is a good idea if not moving the setup around.
