I purchased two 5 packs for a total of 10 Ego Batts this way since I like to change flavors often I can load 9 carts and have 3 different flavors running at once and have 3 carts for each, I would say I never run out of pwer or juice during any day,!!!
good god man! You could never sleep, vape constantly, and still have seven batts charged and ready, lol
