Hey Guys,
Good news!
I was also worried about not having a backup charger so had a search but it didn’t look hopeful until I came across this one from Lumsing
https://www.amazon.co.uk/gp/product/B01KTJ2BGW/ref=oh_aui_detailpage_o02_s01?ie=UTF8&psc=1
It has a USB-C output that chucks out 14.5V/2A so all good. all i needed was a USB-C to USB-C cable which I also got from amazon for £7.88 https://www.amazon.co.uk/dp/B01D175HMO/ref=pe_1909131_77697001_tnp_email_TE_AMZLdp_1
it was only £18,99 from amazon (UK) and just tried it with my Hi13 and works a treat. definitely filling up the battery as can see the charged capacity increase using BatteryBar app. 🙂
