"The battery is rated at 3166 mAh capacity with 35.9 Wh. That means adding an additional 10,000 mAh battery should extend battery life to about 12 hours." This is totally incorrect. Most standard powerbanks like Anker are based on 3.6v. The vision pro is at 13v. It's the total watt hrs that people need to focus on. That said a standard 10000mah power bank at 3.6v is 36Wh, but there is inefficiency battery to battery that results in some loss, so don't expect to get double the time.
