Questions
Where can I charge my laptop in Tbilisi?
At any of these 13 places. Calm ones with outlets: Stamba, Prospero's Books, Littera, TBC Concept and Coffee LAB Lisi Lake.
Do I need a power bank for a 3–4 hour session?
Not at these places. Outlets are at or near the tables. A power bank still helps at busy times, when every socket is taken.
