Best LiFePO4 Portable Power Stations
LFP is now the default chemistry, which makes the marketing claim meaningless. What separates these five is the retention threshold behind the cycle count.

| 5 |  Anker SOLIX F3800 | Best LiFePO4 unit for a whole house | 3,840Wh 132.3 lb | Check price |
The short version: buy the Anker SOLIX C1000 Gen 2, because 80% capacity after 4,000 cycles is the best longevity figure published for any portable unit here and it arrives in a 24.9 lb box that does 2,000W. If weight is what decides your purchase, the Jackery Explorer 1000 v2 is 45.0Wh per pound — but read its cycle rating twice, because it is quoted to a different threshold.
That threshold is the whole reason this page exists. LiFePO4 has become the default chemistry across every mainstream brand, so "LiFePO4" on a box has stopped being a differentiator and started being a given. What still differs — enormously — is what the manufacturer promises the cells will still hold at the end of the rated cycle count.
Why the headline cycle number misleads
Two units both advertise 4,000 cycles. One means 4,000 cycles to 80% of original capacity, the other means 4,000 cycles to 70%. Those are not the same claim. The second unit is allowed to lose half again as much capacity over the same number of charges, and both brands print "4,000 cycles" in the same size type.
| Unit | Capacity | Cycle rating | Weight | Wh per lb |
|---|---|---|---|---|
| Anker SOLIX C1000 Gen 2 | 1,024Wh | 80% after 4,000 cycles | 24.9 lb | 41.1 |
| Jackery Explorer 1000 v2 | 1,070Wh | 4,000 to 70% capacity | 23.8 lb | 45.0 |
| BLUETTI AC180 | 1,152Wh | 3,500+ to 80% original | 35.27 lb | 32.7 |
| EcoFlow DELTA 3 Plus | 1,024Wh | 4,000 to 80%+ | 27.6 lb | 37.1 |
| EcoFlow RIVER 3 Plus | 286Wh | 3,000 to 80% | 10.4 lb | 27.5 |
| Anker SOLIX F3800 | 3,840Wh | 3,000+ (no threshold stated) | 132.3 lb | 29.0 |
Read that table as a ranking of claims rather than of products. Anker's C1000 Gen 2 and EcoFlow's DELTA 3 Plus make the strongest promise: 4,000 cycles against the stricter 80% bar. BLUETTI makes fewer cycles at the same bar. Jackery makes the same cycle count at an easier bar. Anker's F3800 publishes a cycle count with no bar at all, which is the least useful version of the spec.
What a cycle count actually buys you
This is the part most chemistry roundups leave out, and it changes the shopping advice completely. If you camp eight weekends a year, a 3,000-cycle unit and a 4,000-cycle unit will both outlive your interest in the hobby. The cycle rating only becomes the deciding spec if the unit cycles close to daily — a van build, an off-grid cabin, a shop that runs tools off a battery. How long portable power stations last covers the calendar-ageing side, which is the real limit for everyone else.
What LiFePO4 is genuinely better at
Against the NMC chemistry that dominated this category five years ago, LFP wins on three things that matter here: cycle life by a factor of three or more, thermal stability, and tolerance of being left at a high state of charge. It loses on energy density, which is why an LFP unit is heavier than an NMC unit of the same capacity. LiFePO4 vs NMC power station batteries is the full comparison.
What LFP is not better at is cold. Below freezing the usable fraction of any lithium battery shrinks, and charging a LiFePO4 cell below 0°C is the one thing that genuinely damages it — which is why every unit here has a battery management system that refuses to. If your trips are winter trips, power stations in cold weather matters more to your purchase than the cycle rating does.
How to choose between these five
- You carry it — Jackery Explorer 1000 v2, at 45.0Wh per pound. Accept the 70% threshold.
- You want the longest honest life — Anker SOLIX C1000 Gen 2: 80% after 4,000 cycles.
- You run many small things in one place — BLUETTI AC180: 1,152Wh and four AC outlets.
- You need it under 11 lb — EcoFlow RIVER 3 Plus: 286Wh, 600W out, expands to 858Wh.
- You are backing up a house — Anker SOLIX F3800: 3,840Wh, 6,000W, true 240V.
- You are running panels — the EcoFlow DELTA 3 Plus takes 1,000W of solar, more than any unit above.
If you have not yet worked out your capacity requirement, do that before picking a chemistry: what size power station do I need takes five minutes and will usually move you a whole size band. And if expansion rather than longevity is your real concern, best expandable power stations ranks the same registry on that axis instead.
Two small units worth knowing about
Below the capacities ranked above, the same chemistry argument plays out in miniature and the documentation gets noticeably thinner. The BLUETTI Elite 30 V2 publishes "over 3,000 cycles" on 288Wh of LiFePO4 — a real figure, but without the retention threshold that makes the claim comparable. The Anker SOLIX C300, at the same capacity, publishes no cycle rating at all, which on an LFP unit is the gap we would want closed before buying on longevity.
A note on what we did not do
We have not cycle-tested any of these units and we are not going to imply we have. Every cycle figure above is the manufacturer's own published claim, sourced below, and the only thing we have added is the arithmetic and the observation that the thresholds differ. How we choose sets out the method and what it cannot tell you.
The picks in full
1. Best overall LiFePO4 unit
Anker SOLIX C1000 Gen 2
- 1,024Wh
- LiFePO4 (InfiniPower LFP)
- 2,000W continuous / 3,000W surge
- 24.9 lb
- 600W
- 80% capacity after 4,000 cycles
- Full in 49 min (UltraFast, 1,600W max input)
- 5 years
Anker publishes 80% capacity after 4,000 cycles — the strongest pairing of cycle count and retention threshold on this site, and the number that matters most on a chemistry whose selling point is longevity. Cycled daily that is roughly eleven years before it drops to four-fifths of what you bought.
The rest of the sheet backs it up: 1,024Wh of InfiniPower LFP, 2,000W continuous with a 3,000W surge, 24.9 lb, a full recharge in 49 minutes on a 1,600W input, and a 10 ms UPS switchover. At 41.1Wh per pound it is the second-most weight-efficient unit here.
Two AC outlets and no expansion are the trade. The previous-generation C1000 gives you six outlets and a second battery, which is why that comparison exists.
Reasons to buy
- 80% capacity after 4,000 cycles — best retention figure here
- 2,000W continuous, 3,000W surge
- 24.9 lb for 1,024Wh — 41.1Wh per pound
- Full recharge in 49 minutes; 10 ms UPS switchover
- 5-year warranty
Reasons to avoid
- Only two AC outlets
- Not expandable
- 600W solar input, behind EcoFlow
- 1,024Wh is the smallest battery in the 1kWh class here
Buy it if: you want the longest-lived LFP unit you still carry.
Skip it if: you need six outlets or a second battery.
2. Best LiFePO4 per pound
Jackery Explorer 1000 v2
- 1,070Wh
- LiFePO4 (LFP)
- 1,500W continuous / 3,000W surge
- 23.8 lb
- 400W
- 4,000 cycles to 70% capacity
- 1.7 hr wall; 1 hr emergency charge via app
- 5 years (with registration)
1,070Wh of LFP at 23.8 lb is 45.0Wh per pound — the best figure on this site, and 9% ahead of the Anker. If the unit gets carried, this is the one, and the chemistry is the same LiFePO4 either way.
Jackery publishes 4,000 cycles, 1.7 hours to full from the wall, a one-hour emergency charge from the app, below 22 decibels in silent mode and a 5-year warranty with registration.
Read its cycle rating carefully: Jackery quotes 4,000 cycles to 70% capacity, where Anker, EcoFlow and BLUETTI all quote to 80%. Same headline number, easier test. That is the single most misread spec in this category.
Reasons to buy
- 45.0Wh per pound — best on this site
- 1,070Wh, largest battery in the 1kWh class here
- 23.8 lb with a foldable handle
- Below 22 dB in silent mode
- 1-hour emergency charge via the app
Reasons to avoid
- 4,000 cycles quoted to 70%, not 80%
- 400W solar input, lowest in the class
- Not expandable
- Two AC outlets
Buy it if: carrying it, and charging from the wall.
Skip it if: you compare cycle ratings without reading the threshold.
3. Longest cycle rating of the five
BLUETTI AC180
- 1,152Wh
- LiFePO4
- 1,800W continuous / 2,700W surge
- 35.27 lb
- 500W
- 3,500+ cycles to 80% original capacity
- 1.3-1.8 hr full (1,440W max AC input)
- 5 years
3,500+ cycles to 80% original capacity on 1,152Wh — the largest battery in the 1kWh class here, and the longest-rated LFP cell life of any unit on this site measured against the stricter 80% threshold alongside Anker and EcoFlow.
Four AC outlets, four USB-A, a USB-C 100W and a 15W wireless pad make it the best of these five for keeping a lot of small things alive at once, and 1,800W with a 2,700W surge covers everything except heating appliances.
35.27 lb for 1,152Wh is 32.7Wh per pound, the worst weight efficiency in the group. This is the heaviest thing here you would still call portable, and that is the honest framing.
Reasons to buy
- 3,500+ cycles to 80% original capacity
- 1,152Wh — biggest battery in the 1kWh class
- Four AC outlets plus a wireless charging pad
- 1.3-1.8 hr full recharge at 1,440W input
- 5-year warranty; 20 ms UPS switchover
Reasons to avoid
- 35.27 lb — 32.7Wh per pound
- Not expandable
- 500W solar input
- Heaviest unit in its capacity class
Buy it if: a fixed spot, many plugs, and a long service life.
Skip it if: you carry it any real distance.
4. Best small LiFePO4 unit
EcoFlow RIVER 3 Plus
- 286Wh
- LiFePO4
- 600W continuous / 1,200W surge
- 10.4 lb
- 220W
- 3,000 cycles to 80% capacity
- 0-100% in 60 min
- Not published on the US product page
286Wh of LiFePO4 at 10.4 lb, rated 3,000 cycles to 80%, with 600W of continuous output and a 1,200W surge. That output figure is twice what a 288Wh Jackery delivers, which makes it the small unit that runs the most things.
It is also the only sub-11 lb unit here that expands, to 858Wh with a wire-free extra battery, and it charges 0-100% in 60 minutes.
EcoFlow publishes no warranty term for this model on its US product page, which is the one real gap in the sheet. We are not going to infer one from another model's page.
Reasons to buy
- 286Wh at 10.4 lb
- 600W continuous, 1,200W surge — twice the class norm
- Expands to 858Wh wire-free
- 0-100% in 60 minutes
- 3,000 cycles to 80%
Reasons to avoid
- No warranty term published on EcoFlow's US page
- 27.5Wh per pound — the weakest ratio here
- 220W solar input
- 286Wh will not run a full-size fridge for long
Buy it if: a CPAP, phones, a laptop and lights in under 11 lb.
Skip it if: a fridge or a kettle is on the list.
5. Best LiFePO4 unit for a whole house
Anker SOLIX F3800
- 3,840Wh
- LiFePO4 (LFP)
- 6,000W continuous / 9,000W surge
- 132.3 lb
- 2400W
- 3,000+ cycles
- 1,800W max AC input
- 5 years
3,840Wh of LFP, 6,000W continuous, 9,000W surge, true 240V receptacles and 2,400W of solar input. Nothing else here is in this conversation, and nothing else will start a 240V well pump.
Anker publishes 3,000+ cycles and a 5-year warranty, and it expands to 53.8kWh across six packs — a ceiling no household in this roundup will reach.
132.3 lb including the wheels, and 3,000+ cycles with no stated retention threshold, are the two places it is weaker than the units above. Neither matters for a garage installation.
Reasons to buy
- 3,840Wh of LFP with 6,000W continuous
- True 240V output (NEMA 14-50 and L14-30)
- 2,400W maximum solar input
- Expands to 53.8kWh
- Published weight and dimensions
Reasons to avoid
- 132.3 lb including wheels
- 3,000+ cycles with no retention threshold published
- 1,800W AC input, no published recharge time
- Not portable in any normal sense
Buy it if: a transfer switch and 240V loads.
Skip it if: it has to leave the garage.
