Got this magnificent thing for 3.5€ on Temu just to reach the required amount for free delivery. Had power outages during the Hollidays, worked out of the box for at least 7 hours and had some power left. Its rechargeable, USB C.

Large and sudden wet snow fell on Western Serbia at the beggining of January and lots of trees fell and damaged the power lines. We celebrate Christman by Julian Calendar on January 7th..had total power outages for at least 5 days, with like 2 hours of electricity daily(to charge phones, cool the freezers, etc). This thing prooved itself worth every buck. I highly recommend it.
