The voltage in Mongolia is 220 volts/50 Hz, and electrical outlets are identical to those found in Europe. As you venture into the steppe, electricity will be scarce. However, you'll be able to charge your electronic devices at the ger camps where you stay. It's also possible to charge batteries via the vehicle's cigarette lighter outlet—though you'll need an appropriate adapter for this. For backcountry trekking expeditions, we recommend bringing a solar charger or packing spare batteries.
