An E-Rig is an electronically controlled dab rig for your concentrates that gives you several preset temperature settings to heat the quartz coil quickly and precisely. The E-Rig is an evolution in the dabbing market eliminating the torch that is needed with a traditional dab rig. E-Rigs have a built-in lithium-ion rechargeable battery inside to power the heating coil and allows you to use it anywhere.
