Say Goodbye to Dead Batteries with the UGREEN 145W Power Bank 

It depends on your laptop needs. Mine only need about 100w on the MacBook so this 145w is plenty.

@@techbyleon but ZMI and Green gives maximum 100W so there is no difference and takes the same 65w to charge it, I think only Anker 737 gives more than 100W and takes more ?

​@@Jordan_Belforyep Ur right

@@Jordan_Belfor it also depends whether your laptop's type-c port supports up to 100 watts or more. I bought the ugreen powerbank since my laptop (predator helios 300) can only support up to 100 w of charging in its type-c port.

I don't have an ROG Ally (I was interested in it but already have a Steam Deck and Ayaneo Air Pro) but I did a simple Google search for the OEM charger specs, looks like it's 65W. This should be plenty as long as you use the 100W port. I couldn't find info on the required charger volt/amp output, but the UGREEN 145W power bank can handle basically any volt/amp requirement you throw at it. So unless there's another odd variable that nobody mentions, like the Ally only using a proprietary charging protocol, you should be able to charge the ROG Ally, and even another device or two simultaneously.

@@LiL_Miss_Fiasco can you test this with steamdeck? Thanks

@@joelwilliamvalenzuela6161 Confirmed, this power bank works well to charge my Steam Deck and my Ayaneo Air Pro

@@joelwilliamvalenzuela6161 it works pretty good but is quite heavy when you attach it on the back of the steam deck.

yes @@joelwilliamvalenzuela6161
