The Speeder by Aspire is a 200watt dual 18650 mod.
This device has full temperature control compatibility and users can even set a wattage curve. Build quality is very good and the device feels great in the hand.
To fire the device the Speeder uses what I lovingly refer to as a “fire button panel thing” on the side of the device. This button mechanism feels very ergonomic and with the locking features present in the Speeder it is easy to avoid accidental firing. The screen automatically positions itself in the correct orientation and the chipset used on the Speeder has a ton of other interesting features.
Overall this is a great 2 battery device!
