What has your experience been with this? Any advice would be really appreciated.
I have travelled to England several times and got away once without a better power converter, but then the next time it was a nightmare. I strongly recommend you get either a better power converter or arrange to rent a battery charger locally. I ended up buying a UK scooter battery charger since I have traveled to England multiple times and it has been a godsend. It charges slower than a regular wheelchair charger, but still gets a full charge overnight. So, I have not regretted that purchase at all!
In England my North American battery charger shorted when plugging in even though I was told by manufacturer it was fine with simple adaptor.
Luckily I was able to buy a new one from Amazon uk
