Try jumping to the battery directly.
Yeah my experience with mine is that there is some sort of computer or sensor in the car AND in the charger to prevent arcing and sparks. So, the charger isn't just pushing charge out unless it can sense there is a pull for it, and the car isn't looking to just have power thrown in under the hood unless it's forced in. It's like the car and the charger don't stay "hot" on the terminals all the time. The port under the hood is designed to be jumped by another car. When you attach charger cables from another running vehicle, that is power being "pushed" through the cables and then the car can receive it. IDK. But when attaching the charger to the battery directly, it bypasses all the car safety stuff and works.That sort of worked, I was able to get my car keys to lock/unlock the car again.
That was my other thought. The charger pack isn't juiced up enough. Have you charged it? I doubt it came to you fully charged. If it is fully charged, then I'd try just leaving the pack on the battery for a while to let it charge in.My battery pack isn't giving enough power my 12v battery needs to start the engine.
