he most professional GPS handset,has a few car GPS and GPS module. If you are using a battery powered products, go out can bring some more for the way of dry cell possible period of want or need, this is probably the biggest advantage of it compared with lithium battery. But dry cellvolume, and weight also had to face the fact.

Solar power supply

Solar energy can be said to be taking advantage of human, a new clean energy andpositive development, therefore using solar power is also represent the general trend.In order to solve the problem of travel time endurance, the application of solar energyfunction, the GPS module is a good start.

Use this kind of power supply to say with a high sharp sun bird as the representative of the GPS module, in addition to the body of lithium is also equipped with a largesolar panel, to convert solar energy to electricity. At present, the power supply of theproducts can be said to be less and less, although the life time of the problem solved,but the supply is not stable, it will also affect the use of products.

Vehicle power supply

Vehicle power supply basically is the car GPS product design, used in automobileproducts using a vehicle mounted power supply can be said to be the most promisingsolution. But not all products are available using the vehicle power supply, but also forits GPS product is more and more opportunities, so not all can use the car power toyour navigation equipment power supply.

In addition, the GPS product can also be used for charging in the use of DC power supply, USB lines, here we do not put them down to "within the scope of power".Therefore, power supply mode of navigation products, but also is more than four, to buy GPS products don't forget to consider.
