Second silly question, does it have the capacity to run a standard laptop which is 19 volts?
I believe I have a few buck converters laying around to boost the 12 volts up to 19 volts for a laptop and should have a commercially made unit somwhere in my car which powered my sons HP Pro laptop when we were travelling.
I'm not sure of the power draw of my under-powered laptop but I'm interested in saving up for the Bluetti device after hearing too many good things about them.
I've been looking at the larger Bluetti BE70 but it will be a while before I have the funds, a smaller, cheaper unit could be the go.
I guess I'd have to add a small camera into the mix (Player One Neptune with MX178 sensor).
They are certainly more compact and portable than my old jump starter which died (second battery and a replacement battery was near the cost of a new jump starter). I bought a much more compact jump starter to start my old Falcon if needed but I wouldn't count on it running my mount for long.

Hi Leo, I,m not certain what the current draw of your mount would be , but I assume it would be similar to what I have, and not really the item that makes a significant demand on the supply, as for your laptop I dont have anything that uses 19v, mines all USB charged, as to whether a buck converter or a 240v stepdown is more efficient I would guess them to be much of a muchness too. I have used 240 out on the bluetti a couple of times its only 300w but adequate for 240v charging if the need arises. But it will run the wifes blow dryer for only about 15 minutes though...
. The most significant draw on mine is the camera , I,m in the tropics and its running close to flat out to get down to -10. so I dont try to go past that because then it becomes a bit variable.I know another bloke that uses one of those Kings units, a kinda ruggedised outdoorsy type Power supply on his setup, reckons it does the job, and quite a lot cheaper, but takes a long time to charge, I charge my bluetti during the day with 200w solar blanket, and when its fully charged it acts like a pass through 12v regulated uninterruptible with usb charging and 240v @ 300w. I guess if your lappy battery can do a whole session on one charge it wouldnt count as draw for the session hey ?...One thing about bluetti though, they dont make extravagant claims about output and charge times, pretty much you get what the say you get, if not slightly better... I read somewhere that lithium batteries are not all created equally either, different chemistry etc, but thats a whole other can of worms. what I,m citing here is real world experience with the unit I got for the purposes I need it...
