I’m going to add that the math about the Deck having a 5200mah battery and thus with (let’s say) a 25000mah powerbank it’s easy to think that 25000/5200 almost 5 charges… that’s wrong. The Deck has 7.7v battery while powerbanks normally are 3.6 so things don’t translate directly.
Fastest way to know? https://www.steamdeck.com/en/tech/ The Deck has a 40Whr battery, a 20000mah powerbank should be around 74Whr and there the math is clear: less than two charges. Usually on the bottom of a powerbank there’s the specs, should have that value too.
Thanks so much for this, it’s what I really wanted to know.
Is the conversion from mAh to Whr something you can explain to a five year old, or should I really just search-engine that conversion if I need to in the future?

Watts are amps * volts, so the conversion depends on the voltage. So for example 20000mAh at 5V is 100Wh.
