Can we use this product, connected to an external battery, such as a smartphone, for walking, cycling or motorcycling? Knowing that the attachment is of course designed for a car?
It is possible but not practical, the charging cable runs perpendicular to the back of the GPS. You would need a large hand to hold it. I don't see how it could be fixed with an external battery.
Hello,
I used it as recently as the Easter weekend to walk around Beaune and Dijon without any problems. The capacity of its internal battery was sufficient. But I can't answer the question if it is possible to connect it to an external battery, I think not.
Have a nice day
