Quick Answer
Yes, you can charge a Goal Zero Yeti with a car's alternator using a suitable adapter, such as a DC-to-DC converter. This method is efficient and can provide a reliable source of power for your Yeti during extended trips or in areas without access to grid power. However, the charging speed will depend on the alternator's output and the quality of the adapter.
Choosing the Right Adapter
When selecting a DC-to-DC converter for charging your Goal Zero Yeti with a car’s alternator, look for a model that matches your alternator’s output voltage and current rating. For most modern vehicles, a DC-to-DC converter with an output of 12V/20A or 12V/30A should be sufficient. Some popular options include the DC-DC Converter from Goal Zero or the Renogy DC-DC Converter. Be sure to choose an adapter that is designed for your vehicle’s specific alternator output.
Installing the Adapter
To install the DC-to-DC converter, you will need to connect it to your vehicle’s battery and the Goal Zero Yeti. Typically, this involves connecting the positive and negative wires to the corresponding terminals on the alternator and the Yeti. It is essential to follow the manufacturer’s instructions for the specific adapter you choose, as installation procedures may vary. Additionally, make sure to secure the wires and connections to prevent any damage or electrical shock.
Optimizing Charging with Lithium Batteries
When using a lithium battery like the Goal Zero Yeti, it’s crucial to optimize the charging process to prevent overcharging and prolong the battery’s lifespan. When using a DC-to-DC converter, you can usually set the output voltage to match the recommended charging voltage for your lithium battery. For the Goal Zero Yeti, this is typically around 14.4V. Be sure to consult your Yeti’s manual or manufacturer’s guidelines for specific charging recommendations.
