Power bank blowing fuses?

Lisa Miles
Hi all


I have a question I hope some of you might know the answer to.


We've recently moved over from a builders electricity supply to a domestic supply on our new build house in France. The electrics have all been checked out and signed off by the Consuel.


I have a two port USB powerbank manufactured by a well known battery manufacturer (?) and I was trying to charge it up while I was there using a native two pin USB charger plug. It basically fried the charger plug but didn't trip the fuse on the main board... 


I then plugged it in to a four socket extension lead (two pin plug to three pin sockets) using a three pin charger plug I have. It blew the extension lead but again didn't trip the fuse on the main board. 


At first I thought it must be a fault with the powerbank but  when I got back to the UK, I plugged it into my usual charger and it charged up as normal... ??


What do you think the problem could be?

    I do not feel that discussions as to the capacity of the internal battery or the current available at 5 volts are relevant. Any likely figures would correspond to a small fraction of an amp at mains voltage.

    Neither is the mains voltage likely to be relevant, it tends to be nearer 240 volts in the UK and often nearer 220 volts in France, though both are now called 230 volts. Either should be fine.
