I have the same problem. The current draw isn’t enough to keep the power pack turned on. If you use a cable to connect the two ports on the power core it will go into override and stay on for 2 hours. Look for Anker battery packs with the trickle charge feature.I have the Anker PowerCore 5000 cylinder. My super hogster will turn on but won’t stay on even though the battery packs are fully charged. Brand new magnetic cable. Any help? They aren’t brand new battery packs but I have hardly used them.
