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 suspect your power pack is expecting a different current limit protocol to that in the chargers.



    Thanks Mike! 


    So if I take the USB plug I use in the UK and use it there via a two to three pin adapter then that should work? 


    Andy - When the two pin USB charger stopped working I was using one of those multi charging cables with the different connector ends on it. I also used the same cable afterwards ( with the lightning connector) to charge up my iPhone successfully (using a three pin USB charger in a travel adapter) but to be honest I haven't used the micro USB connector also on the cable to attempt to charge anything else as that's the lead that stays in France.


    When I used a different USB charger plug (on the three pin extension lead) I was using the official cable that came with the power bank which then broke the 4 socket extension lead.... 


    As french plugs don't have fuses in them and rely on the circuit breakers I was surprised that the mcb didn't trip which is what I expected it to do when both the two pin USB charger and the extension lead stopped working?
