A LiFePO4 power station is a portable battery box that uses lithium iron phosphate cells. On this site that chemistry is the usual label — 44 of 45 models — not a prize. It names the cell. It does not replace watt-hours, continuous watts, or a cycle claim that includes a percent.
The Jackery Explorer 300ModelJackery Explorer 3008.1 / 10293 Wh · 300 W · 7.1 lb · 3.22 kg · $289.00 and the Explorer 300 v2ModelJackery Explorer 300 v28.1 / 10288 Wh · 300 W · 8.16 lb · 3.7 kg · $279.00 show what that split feels like. One is listed at 293 watt-hours and 7.1 lb (NMC, 800 cycles with no percent). The other is 288 watt-hours and 8.16 lb (LiFePO4, 4,000 cycles to 70%+). Both are rated 300 watts continuous. The chemistry changed; the name alone did not pick a winner.
Is LiFePO4 a better power station?
Not from the name alone. A shirt tag that says cotton is not a size. LiFePO4 works the same way. Of the 45 stations on this site, 44 use it, and the other one is that NMC Explorer 300. When a page leads with the chemistry, it is telling you the battery family. You still have to read the watt-hours, because that is the energy printed on the label, and the continuous watts, because a load above that number will not run.
What you notice in your hand is the weight. At nearly the same watt-hours, the LiFePO4 Explorer 300 v2 is 8.16 lb and the NMC unit is 7.1 lb. An Anker SOLIX C300ModelAnker SOLIX C3007.8 / 10288 Wh · 300 W · 9.1 lb · 4.13 kg · $429.99, also LiFePO4 and also 288 watt-hours, is listed at 9.1 lb. The chemistry leans heavier. It does not lock the weight to one number. If you are picking one of these up to carry, the lightest portable power stationsReviewLightest Portable Power Stations Worth BuyingStations light enough to pick up with one hand. A phone and a laptop are the load. This is not a weekend camping list, and the order is not weight alone. page orders the v2 and the C300. The NMC Explorer 300 is not on that list.
What does 4,000 cycles to 70% mean?
It means the brand is counting charges until the battery still holds about 70% of its rated capacity. A cycle is one charge and one discharge. The Explorer 300 v2 says 4,000 cycles to 70%+. The EcoFlow RIVER 3 PlusModelEcoFlow RIVER 3 Plus8.2 / 10286 Wh · 600 W · 10.4 lb · 4.72 kg · $299.00 says 3,000 cycles to 80%. Both are LiFePO4. The bigger count stops lower, so it is not automatically the longer life.
You will not feel that split on the first weekend. You feel the extra pound. The percent is the part that shows up only after years of recharging, and only if the brand told you where the count stops.
Twenty of the 45 stations here leave cycle life off the page. A blank is not zero. The Jackery Explorer 1500 v2ModelJackery Explorer 1500 v29.0 / 101,536 Wh · 2,000 W · 31.97 lb · 14.5 kg · $849.00 is listed as 6,000+, and the percent it falls to is not always stated. The C300 says 3,000 and gives no percent at all. Set either number beside 4,000 to 70%+ and you are lining up a bare count with a count that states the percent.
Are portable power stations all LiFePO4?
Not on this site. The Explorer 300 is the only NMC station here. Its cycle claim is 800, written as a typical figure for older NMC units, with no percent beside it. That is a different kind of claim from 4,000 cycles to 70%+.
On 2026-10-31 the list price was $289 for that NMC unit and $279 for the LiFePO4 v2. Between these two, 293 watt-hours and 288 watt-hours are not the reason to pick. The pound and the cycle claim are.
What should I check before I buy?
- Chemistry. LiFePO4 names the cell. On this site it is already the usual label, not a ranking.
- Cycle percent. Keep the percent the brand printed. A blank, or a bare 6,000+, is not the same sentence as 4,000 to 70%+.
- Weight at the same watt-hours. The NMC Explorer 300 is about a pound under the LiFePO4 v2. That pound is not a reason to ignore the cycle claim.
Questions
Is a LiFePO4 power station better?
Not from the name alone. 44 of 45 stations here already say LiFePO4. Compare watt-hours, continuous watts, weight, and whether the cycle claim includes a percent.
What does 4,000 cycles to 70% mean?
The brand is counting charges until the battery still holds about 70% of its rated capacity. A claim that stops at 80%, or that gives no percent, is a different sentence. You cannot treat the bigger number as the longer life until both claims state the same percent.
Are portable power stations all LiFePO4 now?
Not all of them. On this site the exception is the Jackery Explorer 300, listed as nickel manganese cobalt (NMC). It is about a pound lighter than the LiFePO4 Explorer 300 v2, at almost the same watt-hours.
Updated 2026-10-01. Chemistry, weight, and cycle claims come from the model pages. List prices for the two Jackery 300s were recorded on 2026-10-31. If a number looks wrong, write through About.
