In Why don't they cloak the jumpers before entering the gate?, one of the commentators says that the puddle jumper does not power the gate.
However, it's established in Stargate SG-1 that the DHD provides power to the gate. There are multiple instances of external power sources (lightning, naquada generators, etc) being used to activate a manually dialed gate (or later via the portable dialing computer).
Each puddle jumper includes a DHD, used to dial the gate without having to leave the confines of the jumper. This is especially important when it comes to space gates.
Is there any in-universe or out-of-universe statement for or against the jumper in SGA being the sole source of power for activating a gate?
