NMC chemistry. It seems like LiFePO4 is preferred for these power banks.

Personally, I would not purchase an NMC unit in 2026.

In most cases, the power density advantage is wasted on something that's already this size and weight, and so LFP is all benefits with virtually no downsides. Cell longevity alone makes NMC a hard sell.

One reason LFP is preferred over NMC is that it's substantially cheaper to manufacture. So the profit margins are much higher for sellers. The energy density of NMC is still substantially better than LFP though. This is the reason why all Teslas Premium long-range EVs and Semi Trucks still use NMC. All Teslas entry level (if you can call them that) use LFP but they are all shorter-range models. When you get into building larger battery packs, the energy density advantage of NMC really shines vs LFP. But it even shows on smaller packs. For example, I have an older Gen NMC Pecron S1500F 1.5kWh power station that's about the size of a 2-slice toaster and only weighs 27 lbs. You can't build a 1.5kWh LFP station that small and that light. It's not happening. On paper, the longevity advantage looks awesome, I just don't think the longevity advantage in the real world is that big of a big deal. Hear me out why. My NMC pecron is rated at just 1000 cycles till 80% bat degredation occurs. Meaning, If I fully cycled it from 100% to 0% and back to 100% every other day (178 times a year) for 6 years straight, that would bring my pack to exactly 1068 cycles and 80% useably capacity, which is still a lot of usable capacity by the way. In 6 years, we'll likely have a cheaper and superior battery chemistry to both of these chemistries anyway. I also don't fully cycle it 178 times a year so its going to last much longer than 6 years. I just don't plan on using my battery station this hard and for that long before I figure I'll be looking to buy something newer, superior, and probably even cheaper in 6 plus years from today. Lastly, I just noticed that this station is rated at 2000 cycles before 80% so you could in theory, fully charge & discharge every single day for 6 years straight without missing before you hit 80% degredation.

Just a few things to consider:-NMC is heavier than newer LFP-NMC has a lower heat tolerance rhan LFP-This model does not use solar charging or Bluetooth-This model has 1 year warranty compared to newer models that offers 3+ years warranty
