Nah, it's different. The madvapes has two connectors, but functionality is the same. The madvapes one isn't rechargeable, you need two AA batteries.
As far as the point earlier in the thread wrt multimeters, yeah I agree--until you build a mess of
coils and want to test them. This rig is worth the $20 I paid for mine in terms of pure convenience. No chance of accidentally shorting something.
YMMV
