You can get a dc-dc converter with a USB socket (eg https://www.ebay.co.uk/itm/DC-DC-Converter-Module-12V-To-5V-USB-Output-Power-Adapter-3A-15W-FT-/134004905372 ) These usually run from 12v but should be fine down to about 8v. That's a bit close to the Hope voltage of 8.4v so it might be worth looking for a more efficient one like this https://hobbycomponents.com/power/215-lm2596-dc-dc-3-35v-adjustable-step-down-power-supply-module but that will need more fettling
