Is there a battery option for the Rigol DHO802 DSO?

Is there an internal battery option, or failing that, is there an external battery pack that will meet the need for 12V and 4A?  Is the 12V DC or AC?

There is no room for an internal battery. You can connect an external USB-C power bank. The scope will negotiate a 15V supply, not 12V, so 3A is enough. (All DC, of course.)

The DHO800 is not exactly a low-power design. At 45W consumption, typical power banks will only last you between half an hour and an hour.

Thank you!  To get at least one hour of service from a power bank with the DHO802 how many mAh would a battery bank require?  Might I be better served by an OWAN XDS3202E with it's internal battery option?  By the time I add the price of a suitable external battery pack to the Rigol it's overall price will be closer to the OWAN with it's internal battery option installed.

As a first approximation, it's  3 Ampere * 1 hour = 3 Ampere hours = 3000 mAh. Multiply by the 15V voltage to convert to 45000 mWh. Then add a 20% margin for conversion losses. And if you buy a no-name power bank from AliExpress or such, add an unknown margin for shameless bragging/lying by the vendor. 

I don't know the OWON scope. Just as a general rule of thumb, Rigol, Siglent and GW Instek are considered the better "B brands"; other brands like OWON, Hantek, UNI-T etc. tend to be a tier below in terms of quality, support (firmware updates) etc.
