Someone suggested earlier that a 100W lamp could be wired
across the open ends.

That seemed a far more practical solution.

Yes - a lamp limiter - common practice for enthusiasts
renovating old radios and TVs - especially TVs.

They usually have a bulb and bulbholder mounted on their work
bench in series with the mains supply with a bypass switch to
short out the lamp when they are satisfied that no damage will
result.

20mm glass fuses may be unsuitable if it's mains fusing, they have low rupturing capacity. A light bulb is a nondestructive option.
Of course if you put a 3A fuse in the plug you don't need one in the charger - purely for testing I mean.

Update:
So fuse arrived today, soldered in to the charger, switched on and POP!
That will be for the bin then as now beyond my understanding of electronics.
At least it never exploded this time.

Ok now waiting on replacement fuse & holder for the other charger,
fingers crossed.
