18650, 21700 or Built-in? Battery Types Explained
Batteries in Portable Vaporizers
The battery is crucial for mobility and usage time in portable vaporizers.
Integrated Batteries
Many vaporizers come with permanently installed batteries that cannot be replaced by the user. This allows for a more compact design and simpler handling – no need to carry spare batteries. The downside is that once the battery degrades, the device often needs to be sent in for repair or replaced entirely. The Mighty+, Crafty+, and PAX 3 all use this approach.
Replaceable 18650 Batteries
Some vaporizers use standard 18650 lithium-ion cells that you can swap yourself. With a spare battery or two, you get practically unlimited runtime. When a cell wears out after a few years, a replacement costs just 5-10 euros instead of a whole new device. The trade-off is a slightly larger form factor, and an external charger is recommended for best results. The Tinymight-2/" class="vc-product-autolink">Tinymight 2, Firewood 7, and XMAX V3 Pro use this format.
Other Formats
The 21700 format is larger than the 18650 and offers more capacity – the Tinymight 2 can use this size. On the other end, 18350 cells are shorter and lighter, used in compact devices where space is limited. The trade-off with smaller cells is roughly half the capacity.
Battery Care Tips
Avoid fully discharging your battery – charge it when it drops to around 20-30%. Store your device at room temperature, away from extreme heat or cold. Stick to high-quality brand batteries from Samsung, Sony, or LG. If a battery shows any sign of damage, replace it right away.

Battery Chemistry Explained
Lithium-ion (Li-ion) batteries power virtually all modern vaporizers. Within this category, different chemistries offer varying characteristics. Most vaporizers use lithium cobalt oxide (LCO) or lithium manganese oxide (LMO) cells optimized for high discharge rates.
INR cells (lithium nickel manganese cobalt oxide) are popular in high-performance vaporizers. They handle high discharge rates well and offer good capacity. Samsung, Sony, and LG manufacture the most trusted cells used in quality vaporizers.
Capacity vs. discharge rate: Higher capacity cells (3500mAh) typically have lower maximum discharge rates, while high-discharge cells (20A+) often have lower capacity (2500mAh). Vaporizer manufacturers balance these factors for optimal performance.
Removable vs. Integrated Batteries
Removable batteries (18650, 21700) offer significant advantages. You can carry spares for extended sessions, replace worn cells yourself, and charge externally with sophisticated chargers. Devices like the Tinymight and Arizer Air 2 use this approach.
Integrated batteries enable sleeker designs and better weather sealing. The trade-off is that when the battery degrades after 2-4 years, replacement often requires professional service or replacement of the entire device.
Battery care tips: Store at 40-60% charge for extended periods. Avoid extreme temperatures. Dont fully drain before recharging. Quality chargers with proper termination protect battery longevity better than cheap alternatives.
Safety Considerations
Always use authentic batteries from reputable suppliers. Counterfeit cells are common and dangerous. Rewrapped low-quality cells may lack proper protection circuits and can fail catastrophically.
Inspect batteries regularly for damage to the wrapper or positive terminal insulator. Damaged wraps can cause shorts. Many vape shops offer free rewrapping services if the cell itself is undamaged.
Common Cell Formats
18650 cells are the most common removable format in vaporizers. The numbers indicate dimensions: 18mm diameter, 65mm length. Quality cells from Samsung, LG, or Sony provide 2500-3500mAh capacity with 15-30A discharge ratings.
21700 cells are newer and larger (21mm x 70mm), offering higher capacity (4000-5000mAh). Devices like the Tinymight use this format for extended battery life.
Proprietary batteries in devices like the Pax 3 or Crafty+ can’t be user-replaced. When these wear out (typically after 2-4 years of heavy use), professional service or device replacement is needed.
Maximizing Battery Life
Charge before the battery is fully depleted – keeping cells between 20-80% charge extends their lifespan. Avoid leaving the device on the charger indefinitely after reaching full charge.
Store batteries and devices at moderate temperatures. Extreme cold reduces available capacity temporarily, while extreme heat causes permanent damage to cell chemistry.
