Usually yes! you can charge your smartphone, tablet, or camera only at the MAIN tent. You can use the power sockets not only to charge smartphones but also for any other light electronic devices. Please note that heavy appliances or electronic devices that require a very huge amount of power is not allowed to use in the sockets. Our electricity generation is limited to the maximum power preserved by the solar panels near us. Therefore to provide electricity for everyone equally, we request the oncoming customers not to bring any appliance which requires heavy electricity. That will not only work but also increase the burden of your luggage.
Also keep in mind that, all the sockets are available in the lounge and restaurant areas but not in your tent. So, you can definitely charge smartphones, tablets, or your cameras while having the food. We recommend to bring a power bank battery so you have battery all across the trip.
