Haktuspit still had to go to Starbucks to access WiFi, so the point is moot at best.
Btw, those xtar VC2 and VC4 just needs an USB. Either wall, computer, power bank, solar, automobile, etc. But even these won't give Haktuspit WiFi.
I was using my XTAR VC4S to drain a couple of dozen cells down to storage charge. But a day later, I too had a power outage. Now I could have used all of those cells I just drained. Live and learn. Luckily my power was only out for 8 hours.
