Extra power when you need it!

Ecoflow has always been my favorite when it comes to extra battery power. This small but well designed extra battery will double your current river pros power capacity and trust me when I say it, you will love the extra power.

Thank you for your review, and we are huge fans of EcoFlow products as well. We're glad the battery is working out so well for you. Please let us know if there is ever anything more we can do to serve you!
