In order to make the NUC PC system portable for at least 3 hours, there has to be an UPS battery.
Is there now something already to exchange the size of the mSATA SSD with battery power in the NUC?
Looking at https://www.amazon.co.uk/CompuLab-fit-Uptime-Black/dp/B01704YBA8 reviews about the Fit-Uptime UPS they all state that it does not work. And intel service has mistaken validated this device http://compatibleproducts.intel.com/ProductDetails/ExportPeripheralInfo?moduleName=Intel®%20NUC&productType=Kits&productName=Intel®%20NUC%20Kit%20NUC7i3BNH here, because the Fit-Uptime UPS does not also support screen. And who runs a nuc without screen?
Are there other (lightweight portable) UPS batteries available to buy in Europe that can power NUC + http://www.asus.com/us/Monitors/MB16AC/overview/ USB powered screen for at least 3 hours and be bought elsewhere than in the amazon jungle?
