How many MAh is the 55 watt hour battery? (alien.top)

Hi guys, I’m looking to get an AMD framework, and I was just wondering if anyone knew the mAh of the 55-watt-hour battery? The reason I ask is because I’m looking at buying a portable charger, specifically this one: [https://www.baseus.com/products/adaman-power-bank-65w-20000mah?variant=39912115798093], and I was curious how much it’ll charge the framework when the framework is at rest or if it will sustain it while I’m doing light to moderate loads. The reason I ask is because I’m kinda new to this and looking to use the power bank as a charger since I can’t plug the laptop in myself when I’m out and about. (I’m in a wheelchair and can never reach wall outlets.) Thanks!

mAh mean nothing outside phones, because they only convert to an energy unit if they are paired with a voltage. The reason why it's valid with phones is that they all have the same voltage, so it's always an apple to apple comparison. If you change device type, it doesn't make sense anymore.

For example, my Pixel 6 has a 4700 mAh battery at 3.75 V = 17.6 Wh. But if the voltage was, say, 9V, then it would be 42 Wh. Which is a battery twice the size.

You can't compare mAh across device types which don't share the same voltage. Which is also why I hate it so much that it's become the standard way to talk about batteries for phones.

mAh means nothing even in phones... it doesn't tell you how long it could run, nor now many times it could charge a given device. It's a d*ck-measuring contest between arbitrary numbers, that's like the GHz race but for batteries.

God, I very deeply wish we could get the industry to stop using mAh as a measure printed anywhere but the lowest, trivial details of a spec sheet - which is all it really is. Watt-hours (Wh) are the real measurement, where you can understand and compare real, functional data.
