> <i>Elecom says the Na Plus can operate in temperatures ranging from around -30 to 122 degrees Fahrenheit</i><p>Nice perk. 122 F doesn't sound like a ton.<p>45W for a small-ish pack like this is pretty power dense. I wonder if it can charge at 45W too?<p>5000 cycles is comparable to LFP, quite decent.<p>Others have already discussed, yes, it's not nearly as energy dense as li-po. It feels.lile it performs closer to LFP, with high currents, better temp flexibility, good cycle.count, high safety. Would be neat to have the exact energy density figures for all three.
