Hi all , I have a chinese gps that came with the car charger but no wall charger. I have a charger marked 5.1v , but Inotice on the car charger it says 5v. the amps are ok, can i use the 5.1v on my 5v gps?. I know this is not a big difference,but no wish to fry gps!
The battery is 3.7 volts DC.
Normally chargers will have higher voltage to facilitate the charging.
Same with phone chargers.
0.1 excess should no harm but even better.
Just ensure you have the proper fuse installed to prevent over-voltage due to surge from vehicle alternator
Thank you airion, I did not make myself clear,sorry. The problem is with a wall charger.I have a 5.1v wall charger and want to charge the 5v gps with it.But I guess that the same answer would hold?..Thanks again
