Sodium-Ion Solar Generator

Anyone take a look at the new Sodium-Ion Solar Generators?

Bluetti is touting charging of the NA300 solar generator from 0-80% in just 30 minutes.
Retention capacity of over 85%, the sodium-ion battery pack of the NA300 and B480 can offer 80% efficiency when operating at low temperatures.

Anyone using prior generation Bluetti Solar Generators?

Sodium-ion is new to me, but I’ve been happy with my prior gen Bluetti. I’ve got the AC50S, which uses just regular old Li-ion, and have been pretty happy with it.
