A large battery, a variety of AC and DC power ports, and a solar generator all in a compact and lightweight package that’s easy to take along on any trip.
The Jackery Explorer 1000 powered just about everything we threw at it, from a mini-fridge for the car to air pumps for air mattresses and inflatable paddleboards.
For reference, iPhones have batteries with about 10 watt-hours and our Sony A7 camera battery is about 7 watt-hours, so we could charge over 100 of those batteries on a fully-charged Jackery 1000.
