GPS hookup on a snowmobile.

If you are referring to a 12V DC - to -120V AC converter, then the answer is obvious. The converter makes the AC from the DC voltage provided by the batteries. You cannot charge a DC battery with an AC source. Additionally, even if you could, the resulting charge would be less than the draw taken from the battery (physics - loss from heat). Also, there wouldn't be enough power left over to do anything with.

Yes. Either by using a 12v dc tv, or if it uses 120v/240v ac by using an inverter on the 12v dc supply which ups the voltage and converts to ac.

dc will not power ac, soorry

You cannot convert an AC charger into a DC charger for a cordless tool, no matter what you do. The charger has a transformer that operates only on an AC current only. You did not state what battery your drill has, but a range of chargers are available for cordless tools, as long as the batteries are 12v or less. Speak to your hardware outlet.

I Have a 2010 Polaris Shift (with No electric start) and over the clutch on the left side (sitting on the sled) is a bunch of plugs, one with 4 wires.. and a longer plug with even more wires.... The One with 4 wires has a Yellow wire that produces about 10V AC, which is a good tap for a electric shield. The Longer plug has a solid Red wire which produces around 13.5V DC, which is a good tap for your 12V Plug. Connect your positive to the red wire and your ground to the brown wire (also your ground can be securely attached to your frame by a nut located just above your plugs on the frame) and your good to go!.. with the 2010 shift you don't need a battery for it to produce DC voltage.

Hi!

Incredibly, the AC charger for your GPS is incredibly inexpensive.

I found a link where you can purchase them for a very good price!

Hope this helps.

You haven't supplied enough information. An inverter only converts 12V DC to 115V AC. There are some battery packs with inverters, but that's not what you asked about. The time it "serves" is dependent on the load being connected and the battery(s) that the inverter is being supplied from. Go to a web site such as :http://www.donrowe.com/inverters/inverter_faq.html#hookup
You can learn a lot about inverters here.

The alternator.
It should produce 13.5-14.6 volts DC when charging a 12V battery

I found there are select 120v AC adapters that will work on Magellan GPS. When a working 120v or 12v adapter to mini USB adapter is plugged into the unit, the battery bars will be 'scrolling' and therefore charging.

When your adapter, or even USB cable from your computer, is plugged into the GPS unit, and the battery goes to FULL, it is NOT CHARGING. The battery bars must be SCROLLING for the unit to charge. In this case, get a different adapter until it works.

This system uses in conjunction with the transformers a rectifier which converts the High AC current voltage (220V-AC) to a Low AC current voltage (12V-AC) and then the rectifier converts that energy into the D/C current (12V DC). The two diffrent 12V power sources are controlled, operated by a "electric" relay, via a roadside or electric selector switch. DS_TK TECH
