During our 8-Day Jordan Trail trek, you should not expect to have much access to electronic charging. After leaving Amman on Day 3 with your fully charged devices, our next decent charging opportunity will be at the Bedouin Camp in Little Petra on Day 7. You can charge your devices there until around 10pm when the camp turns the generator off for the night.
If you want extended access to electronic devices, we recommend bringing a reliable battery pack or solar recharging device.
