Designed for heavy gas and diesel engines up to 16 liters but also suited to cars, minivans, and SUVs, the Noco Boost Max 250+ 5250-Amp 12V Jump Starter will keep your fleet rolling and your equipment on the job. This 242 watt-hour lithium-battery jump starter provides up to 5250 peak amps to start depleted batteries safely, with no-spark technology and reverse-polarity protection. Use the 60-second timer to conserve power—if the engine isn't restarted within that time, the jump starter must be powered off and back on to try again.

Along with starting your biggest engines, the Boost Max serves as a power bank, with a 12V outlet for operating tools, appliances, inflators, inverters, etc., and a USB port to power or charge smartphones, tablets, cameras, etc. Finally, the unit is equipped with a 600-lumen light, with seven light modes including SOS and strobe. The unit can be fully recharged and ready for jump-starting in 8.5 hours from a vehicle 12V auxiliary port or with its XGC4 adapter plugged into AC power.

Q: 1. Looking at this for freelance work with DSLR, at my regular job we have a Canon XA35. Would it work with the Canon?

A: It will indeed work with the Canon. Remove the off-set that is needed for the DSLR to set up for the XA35. (With the XA35's LCD open, you do not need the rigs off-set.) I am not seeing how the follow focus would work. I also do not think you need that.
