I am new to the whole portable power units when camping. I love the AC60 IP65 rating, but I also love the AC70’s increased power, and additional USB C ports. Why not combine the best of both for a better mid range camping unit. Take the AC70, add the IP65 dust and water resistance, add the battery expansion capability. I am sure there are a bunch of others that have this same idea, so it should be an easy model to build and test. I believe the IP65 rating should be standard for something that is touted as a camping/outdoor power unit. Just my 1/2 cent.

Agreed. AC60 has this useful swivel handle too, but it misses AC70’s voltage range to allow full-sized panels.
Hey @Hercule_Poirot

I agree, I have an AC70 and love it, the AC60 has advantages, but is just a bit too low in its W /Wh for my uses
