“Not published” means the manufacturer’s specification list for that device does not state the value.
What the differences mean
- Capacity: the Pulse X holds 18 mL against 16 mL in the Pulse, so at the same rate of use it lasts about 12% longer.
- Battery: a larger battery means fewer charges between the first puff and the last, not a longer-lasting device. E-liquid decides that.
- Modes: both have a regular mode and a higher-power pulse mode. Pulse mode uses e-liquid faster, which is why each device carries two puff ratings.
- Price: $2.00 separates them at Vaperan.
Which one to buy
Pick the Pulse X if you want the longer run time, the 3D curved screen and adjustable airflow, which the Pulse specification list does not mention. Pick the Pulse 15000 if you prefer the smaller, lighter device or a flavor that only it offers. Flavor ranges overlap but are not identical; compare them in our Geek Bar flavor list.
