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!
The nominal mAh of the 55Wh battery is 3572mAh
HOWEVER that is at 15.4V, while the Powerbank you linked is 20000mAh at 3.7V
So I’d actually recommend doing this the other way around, calculating the Wh of the Powerbank, because Wh is an actual representation of Energy stored inside the Battery, while mAh is only telling you half the story.
And multiplying 20Ah with 3.7V, we get 74 Wh, so that Powerbank is gonna charge the FW 13 about 1.3 times.
Given average battery life reports between 8-12 hours, that should give you between 18 and 27 hours of non-stop use (Laptop Battery + Powerbank),
I’d stick with the 18h estimate, both just to be sure and to account for Windows (assuming you’re using it) thinking “Ohh look I’m plugged in so I can use even more power now to run random background tasks”, but 18h of run time should still suffice for most if not all situations.
Most powerbanks can only transfer 75% of the power (power loss is the rest. At least that’s the case with me bases 65W)
Honestly I wish the EU would get on board and require that batteries be labeled by energy content, not “Ah”
Amp-Hours is a bullshit non-stat.
