Good quality Nitecore 18650 with USB charging port
September 1, 2022
I have many 18650's from different manufacturers. Nitecore is on top of my list along with Olight. Has the actual capacity as advertised. Works well in my torches & other devices. Can simply charge the battery from the micro USB port on the battery. This is very convenient if you don't have a charger around & just a micro USB cable & power source. ie, DC USB car adapter or power bank.
