I would have to have my car running or my battery would die but yes that could work as well!
I've used portable generators in the past and they work totally fine, I was looking for something that can be solar powered and self contained without running extension cords or needing other gear.
I settled on the batteries and this additional power bank for my mixer which I also use to solar charge the batteries.

So everything you see is solar powered and self contained, which I prefer, but you are 100% right there are other ways to do it.
Perhaps the best way would be 2x the rockpals which provide 3x 12v DC each, and can be directly solar powered. It just won't fit in my case.
What do you think about this?

My goal is to run a macbook pro 15" each day for about ~5 hours. This particular device claims it can recharge a laptop 5 times which, starting from a full charge and lasting about 45 min per charge should be something like 4.5hrs of use.
Do you have any experience with these kinds of portable battery systems?
Hmm.. I'm not familiar with Boosted boards, but I know for the OneWheel XRs that can't do the "CnR" either use a portable power generator like this one

or they make a Charge and Ride setup with the third pin connected so they can't charge while on the move, but still can charge with the eBay batteries sitting down. The good thing about this setup is that you can control the amperage for charging. In the case of OneWheels, they can handle safely to charge around 5 amps. That charges really really quick so even just sitting and waiting for it to charge isn't too bad. It does, however, affect the battery's long-term condition and whatnot so there are trade-offs.

You might be able to solder in a whatever cable the Boosted board uses to charge and pretty much do the same setup. Just have to make sure what voltage and amperage you need to be at and put it to that setting. That said, this is just speculation because I haven't even touched boosted boards before so you're probably going to have to do some research if that would work or not.
