Ovide Smart Assist's transport case has the dimensions and weight to travel by plane as checked luggage.
Ovide Smart Assist has a super bright screen, but if you are shooting in a exterior sunny location you may need a sunhood.
If you are shooting in a dark location you won't be able to read you paper documents (like scripts), a reading lamp could be really useful.
Fanless power supply
Ovide Smart Assist can be powered by camera batteries, but sometimes you may preffer to power it with a power supply.
Cheeseplates can be fixed on the top of your unit, they are perfect to attach accessories like mini-monitors or wireless transmitters.
You can also fix handles on your Smart Assist to move it in a much confortable way. These handles are also made as cheeseplates, so you can attatch accessories to them.
