Ok, so maybe blenders aren’t a top priority in an emergency/EOTW situation. But we should have “every needful thing” and let’s face it, sometimes we will want to blend things. When it comes to off grid blenders you really only have two options;. the brand new Coleman Rechargeable Portable Blender or the Vortex Hand Powered Blender. While the Coleman would work a little bit better, for storage and self sufficiency the Vortex wins hands down.
