EF EcoFlow Wave 2 Add-on Battery, 1159Wh Battery for Portable Air Conditioner (Wave2 Not Included)

This battery is needed to make the WAVE2 a stand-alone machine without a power cord. It works great and holds an awesome charge. I didn't know I needed it until I got it - but happy I have it.

The additional battery makes the Wave2 more practical by providing enough power to run the Wave2 for over 8 hours and allows solar charging. Generally, works as advertised.

I bought this product and I am happy with its good design , customer support and the rewards of eco flow credits . As I am trying to cool down the summer , but oddly enough last night I used the heat setting cause the temperature dropped in to the 50s , with a constant breeze . But the wave two and the delta 3 did its job and with out losing less than 2 minutes I changed the settings to warm me up real nice . As I am working in the field this willl be the best option I have purchased with a smile of a winner against the elements . But I still want more like carry bags and extras attachments in case I need quick replacements . I am now a certified Ecoflow dependant customer . I am planing on making cars vans and what ever you ride a business . I can only tell you that every one that sees my suv with the new eco flow vent window cover saying this is Ecoflow portable a/c and added extras . In the last month I have record the highest ratings by other suv and sprint van van life people . Truly I can say my car is not taking an over idling problem . That is the worst thing to do to your car . I can not wait to get a roof rack with your solar panels .

Well just a little disappointed because I have gotten the first Wave and now with no extra battery available because it's deemed obsolete. However Wave2 is so much better I couldn't pass it by. I'm very satisfied with my purchases.

So far so good. You must use this with wave 2 ac unit. It gets recharged from the ac unit when the ac unit is plugged in. This is not a stand alone piece. If you are looking for just a battery pack, ecoflow has better options.

Nice unit, but eco flow need to have a larger batter for the wave 2 so it can run 8 hrs and someone does not have to get up to change batteries in the midle of the nigh. As an opton Eco flow needs to be able to connect two of the existig batteries together so one will have unimited power while sleeping. It gets hot in Texas and the eco mode just does not cut the mustard.

This unit works great. The app is well designed and it does what they claim it will. The two downsides are the inability to accommodate other 13v. Power without the add on battery and the necessity to charge the add on battery only when connected to the wave unit. It would be nice to be able charge an extra battery so you can power it longer.

I got my Wave 2 in May and it cools well but it will no longer run off of a/c or charge off of a/c. It works from my delta 2 but you can not charge the battery and run the wave 2 at the same time. Over all I have to say the add-on-battery was a waste of money.
