without knowing too much should be fine.

If they are both in fact 12 volt chargers, there should be no issue.

a 24 AH sealed lead acid battery should cop a couple or 3 amps no sweat.

In general recomanded ideal charge rate is arround 10% of Ah capacity.

Most 4 ah SLA batteries will cop over an amp.

The current rating (the 1A or 1.25A rate) on the charger is the maximum the charger can deliver.
The rating on the device (the Jump-starter) is the maximum it will draw.
So long as the latter (the requirement of the device) is less than the former (the maximum deliverable by the charger) it will be fine. Of course, this assumes that the voltage is the same on both. And, if the voltages are different, it makes no difference - they are not compatible.
