Now , I realise very few caravanners will carry that much solar capacity but also consider you could connect two of EcoFlow ’ s 400W bi-facial portable solar panels and recharge in as little as 2.8 hours .
If you have access to 240V mains , the Delta 2 Max can be charged at up to 2300W from a standard 10A outlet in a little over an hour .
The Delta 2 Max also shares the same variable charge input function as the Delta 2 . Here , you can set that actual AC charge wattage via the EcoFlow app from anywhere between 200W and 2400W . This is extremely useful if you have an inverter in your car or caravan .
Using excess solar input from your rooftop panels , you can set the charge rate to a level that will not impact your batteries ’ state of charge .
The Delta 2 Max is larger than the Delta 2 .
Of course , you can also recharge the Delta 2 Max from your tow vehicle ’ s 12V system . At present , you can plug directly into a cigarette lighter outlet and charge at a rather slow 100W . You can also connect the Delta 2 Max directly to your car ’ s alternator output and charge at around 200W , or wire up a Victron DC-DC converter and charge at a respectable 400W .
EcoFlow recognises these rates may not be fast enough for owners of the Delta 2 Max and , in response , have announced that it is about to release its own DC charger that will be able to deliver up to 800W of charge . This unique system can also be connected to a caravan or motorhome ’ s house battery as an option . We can ’ t wait to get our hands on one !
THE ECOFLOW APP
One of the best things about owning an EcoFlow product is the smart device app . It is brilliant . You can control and monitor all aspects of the Delta 2 Max ’ s setup and operation . You can control the power to the 240V , 12V and USB outlets separately , set the AC charge rate , check the battery level and monitor solar input . It is intuitive and very easy to use .
