Starting Location: All Charged Up
This side mission starts in the place where the previous side mission Null and Void ended.
Push implosion drive onto loader
Directly above the quest giver, melee attack the red marked metal pod. Then it falls down onto the loader.
Meet Outbounders at Order hydroplant
The next objective is 450 meters north-east. You can fast travel to the nearby safehouse to glide to it. When you arrive there will be a bunch of enemies fighting your allies.
Kill Order guards
Defeat all enemies.
Talk to Rhodes
Afterward talk to Rhodes who stands upstairs at a locked door.
Open loading bay
Interact with the console behind Rhodes. A 60-second countdown will start. Enemies will spawn, fight them off while ECHO-4 hacks the door.
Escort implosion drive
Hit the switch on the back of the implosion drive transporter, then kill the enemies behind the door.
Unlock elevator
When the transporter reaches a locked door, interact with the green switch across from the door.
Escort implosion drive
Now hit the elevator button. Continue to defeat the enemies along the way.
Reach hydroplant reservoir
Your allies will enter a door and disappear. You must advance solo. Take the path to the right of where your allies entered the door. Follow the location line, it will guide you there. After going upstairs you must glide over a gap to reach the reservoir.
Drain water
Use the green cogwheel on the side of the water reservoir.
Release loader
Hit the switch on the other side of the reservoir, up the stairs. This will spawn some enemies. The objective automatically updates after about 2 minutes when the implosion drive arrives on the central platform in the drained reservoir.
Lower loader
Flip the switch on the central platform where the implosion drive arrived.
Destroy drone
This will spawn some flying drone enemies. Defeat the biggest drone to advance.
Enter reactor maintenance
On the west side of the reservoir, go through the door. Close to where you entered the reservoir.
Raise reactor
Go through the facility until you reach a red-lit console room, hack the green computer.
Find reactor components
You must find 3 components. They are all scattered in front of the computer you hacked. If you scan with 
they will be highlighted in blue from afar.
The first is on the right path.
The second is directly above the first, up the stairs.
The third is on the left path.
Install reactor components
Jump down to the reactor in the middle of the room and interact with the green points.
Lower reactor
Go back to the console room and flip the switch next to the computer you hacked.
Lower loader
Backtrack outside to the reservoir and flip the switch on the central platform again.
Escort implosion drive
Follow the implosion drive through the now-open path, down the central platform in the reservoir where you hit the switch. Keep killing the enemies along the way.
Unload implosion drive
When the drive stops, hit the green button on its back.
Activate reactor
Go up the stairs in the corner of the room and flip the switch.
Defend implosion drive
Looks like your Outbounder friends forgot an important step: to clear out the enemies before activating their reactor. Lots of enemies will spawn. Defeat them all. There will be multiple waves of Badasses. You can’t do anything wrong here, there’s no timer and they can’t actually destroy the reactor. If you are severely underleveld and all enemies have a red warning icon, you may need to come back to it later. Luckily, if you die you don’t need to defeat all enemies again, and there’s an ammo vending machine in the same room. Use the room in the corner upstairs for cover.
Eject implosion drive
After all enemies are defeated, hit the button on the reactor in the middle of the room.
Follow drive to lower-level
Where you pressed the button, you can now jump through the open reactor in the middle of the room. This leads down to the caves with a boss. This one scales to your own level.
Kill Sludgemaw
Defeat the Sludgemaw boss. He is a big Thresher. He will dig into the ground, attacks with his claws, and throws rocks at you.
Inspect implosion drive
After the boss fight, interact with the blue glowing implosion drive in the middle of the boss arena.
Leave lower-lower level
Pull yourself up the grappling hook at the end of the boss arena on the ceiling. Rhodes will stand where you land.
Talk to Rhodes
Talk to Rhodes to completed the mission.
This finishes All Charged Up side mission in Borderlands 4 and unlocks the next mission Bound For Launch.
