The Geekvape Griffin 25 Mini is an upgrade Griffin 25 RTA but in a smaller form factor and with improved quality.
With dimensions of just 25mm x 36mm, it is a very portable RTA. Compared to the larger Griffin 25, any leaking issues have been eliminated.  The Griffin 25 had two versions: a top airflow and standard one.  The Mini 25 is a combination of both.  You’ll get two alternate drip tips for a customized vape.  The 510 contact pin is adjustable for adaptibility and gold plated for best electrical conductivity.
The Velocity style deck on the Griffin 25 Mini measures 18mm across.  It has been changed to provide more space for building and to leave more room in the tank for e-juice.  A ceramic block is included for a single coil option.  The tank capacity comes in a 3ml which is very adequate for a portable RTA.  It is refillable via an easy top fill system. Airflow is located at the top and at the bottom of the RTA.  Bottom air intake works identically to the standard-sized Griffin 25 and is fully adjustable.
