Are there any power banks that output enough to charge it while playing? I have some PD power banks but when I connect them it says they charge too slow.
I have the Anker 737 Powercore 24k powerbank, which is a 24.000mAh power bank capable of charging and discharging with 140w, which makes it a perfect Steam Deck powerbank as it can charge itself super quickly while still expanding the Steam Deck’s portability massively.
Can charge the powerbank in 1 hour or less, while adding over 10 hours of gameplay to the deck - or more, depending on how power hungry the game is.

When looking for a power bank suitable for the Steam Deck it needs to support atleast 45W Charging and you a suitable cable that will support this capacity (i.e a DECENT quality 3C cable).
I use a 20W power bank and it just about prevents the drastic battery drain. A 30W one should be good for most games I reckon
A 30w will suffice but to ensure charging under all circumstances regardless of load, 45w is the benchmark. For context, the charger that is included out of the box is 45w.
