The battery charger that I got with my Olympus Tough TG-5 (left) looks pretty different from any typical USB charger that you see here in Europe (right).
But in spite of its somewhat unusual and bulky appearance, it seems to work just like any other 5V 1.5A USB charger. I can use it to charge a mobile phone, and more importantly, I seem to be able to use any modern USB charger to charge the battery of the camera.
So is there anything special about the Olympus charger? Is it really just a normal USB charger?
The user manual is unhelpful; as usual, it instructs against using any third-party charger, but this is what you find in the manual of any mobile phone, too.
