If you’re taking stock for your camping trips for the summer, you should make sure you have a portable power station on your list. These battery units have enough juice to keep your fridge, speakers or laptops charged for days on end. Plus, you can often daisy chain them or plug in a solar panel for more power. 

The EcoFlow Delta range includes four models, starting with the Delta 2. It provides 1kWh of storage and can be paired with a second Delta 2 or a Delta 2 Max battery for up to 3kWh. It will provide 1800W so it can even cope with high power devices like fridges and portable AC.
