One of the battery has stopped working

Useful product

Le chargeur marche très bien avec son indicateur de charge. Les batteries sont parfaitement adaptées. Je ne suis pas capable de déterminer si elles permettent de prendre plus ou moins de photos et de vidéos que celle d'origine car je ne fais pas deux sessions identiques et que je me sers beaucoup du zoom de mon Sony RX10 IV qui consomme pas mal à lui tout seul. Quant à la longévité je n'ai pas assez de recul. À ce stade je suis satisfait.

Works fine; the charger charges pretty quickly (18W if I remember, when charging both batteries). Independent circuits for each battery. Nice and small, portable enough for the camera bag. The batteries so far seem to work well, though we'll see how they hold up to heavy use over time.

These batteries work well and charge pretty quickly. I got this brand because I have other Neewer products and never regretted it. The price point was also a factor.

Clean, light, quick charger. One battery came in already dead. It looks like is charges at the beginning, then the charge indicator goes blank and the battery simply doesn't work. The other battery works ok, full charge lasts about 80% of an original Sony - I saw reviews and stats, but my experience disagrees with those. The issue is that the dead battery does not work AND the battery spot doesn't charge other batteries. UPDATE: Neweer support reached out to arrange a new charger delivery. Support is very kind and cooperative.
