Brilliant. I have to do a 3 hour bus trip every other week for work so this will definitely help next year.
Did you get any interesting looks from the other passengers on the plane? 
18 hour flight to Bali coming up. This might ease the pain slightly.
how long was the flight? and how long was the AR on ? cudos for first AR reported on airplance picture!!! [/quote]
It was only a few hours flight and I played Analog RYTM about 2-3 hours. It consumed about 1/3 of battery capacity so I guess it can operate about 6 hours or so?

thanks!
Just a few! The guy next to me was very interested in a suspicious kind of way. Should probably have made more of an effort to bop around to show Iâm actually making music, rather than blowing up the plane 
Looks great!
FWIW, All my machines are connected to the regular but small UPS just in case of power outage. I wonder for how long it would provide a current if used as a battery for one Elektron box. Itâs not that portable, but the battery is big.
Sorry to revive this older thread from the dead.
Very keen on getting mobile with the RYTM.
Lots of great suggestions in this thread but none of the branded batteries seem attainable here in the uk.
Are there any UK based Rytm users that are successfully using a specific battery they could recommend? Was looking to pick something up easily through amazon/maplins etc
I wanted to bump this thread and ask users sloppy23, onoffon, and petal: Everything still working out with your RavPower Xtreme 23000 after a couple years? Bought to pick one up so I can take my RYTM on a road trip.
All my elektron gears are fine. But it seems my battery is dead. Actually battery it self is fine but LCD on the battery is not working anymore.
I have to buy a voltagemeter.
wow! Good find, the omnicharge looks like a winner! Over 20k mA and 100W 
Sorry to necro this old thread, but I am having serious trouble finding a 12V 2.5A DC outputting battery that ships to Finland (EU). Amazon.de .co.uk .com - none of them will ship these type of batterypacks to my country 
And that omnicharge, while being awesome, does not seem to support EU 220V?
Surely this canât be this hard to find⊠Any ideas?
Maybe that?
