A standard 510-thread battery works with most THC vape cartridges. Look for one with variable voltage (3.0-3.8V) so you can adjust the temperature for different cart types and personal preference.
A 1ml cartridge typically lasts 200-400 puffs depending on draw length. For most users, that's 1-3 weeks of regular use. Half-gram (0.5ml) carts last roughly half as long.
Live resin carts preserve more natural terpenes from the fresh-frozen flower, delivering a fuller flavour and a more balanced, strain-specific high. Distillate carts are typically higher THC but have a more uniform taste.
