Question

Can I use a charger with my GPS that has a little lower current than my GPS car charger?

Answer 1

If the voltages are the same you can "try" it.

The unit with lower current will take longer to charge the unit (since it does not have as much capacity to charge.)

You may find that one or all of the following occur.

1. The unit with lower current may get very warm or burn out while attempting to charge the unit.

2. The lower current unit may not even charge the unit.

3. The lower current unit probably will not operate the unit while you charge.

The main issue is whether there is enough current to charge the battery. So the real question is HOW MUCH LOWER is the current available.  A small amount of difference is probably no big deal. If it is only 1/2 or less then you probably won't get a charge - it won't damage the GPS but it may not charge it either!  Just be sure that they both are the same polarity and same voltage!  Either of those will cause major issues!

I wouldn't attempt to RUN the unit on the lower current but attempting to charge it, maybe!
