Where This Comparison Comes From
Every figure in this article comes from one source video — Minute Man Solar's EcoFlow vs Jackery vs Anker SOLIX comparison, watched more than 780,000 times. The host has been testing solar generators for nearly a decade and has tested hundreds of units, and in this video he lines up three of the best-selling mid-size units side by side: the EcoFlow Delta 3 Max, the Jackery 2000 V2 and the Anker SOLIX S2000. If you would rather watch the comparison before reading the breakdown, the video is right here:
The test answers the question that matters most to people buying their first solar generator: which one should I choose for a 12-hour blackout, and is one unit actually better than the others? The honest answer from the video is "it depends on your situation" — but one unit does come out ahead on pure value, and the reasoning is worth reading carefully. Below is the full breakdown, every number taken from the on-camera tests.
Why These Three Units Are Worth Comparing
These three are among the most-sold portable power stations in their size class, and they share surprisingly similar battery capacities. The core idea of a solar generator is simple: everything is pre-wired — battery, inverter, charge controller and outputs in one box — so you skip the confusing wiring decisions of a DIY system. All three brands are equally competent on build quality, which is exactly why the comparison comes down to specs and numbers rather than brand loyalty.
If you are sizing any battery system — whether a portable power station or a permanent bank — the same three pillars decide everything: how much power it can output (inverter), how long it lasts (battery) and how fast it recharges (solar and wall input). Those are the dimensions this video tests, and they are the same dimensions we talk about in our battery product range and in our sizing guides.
Inverter Output: the "Engine" of Each Unit
The inverter is the engine of a power station — the bigger it is, the more you can run, but the more it tends to cost and consume. On this test, the Delta 3 Max leads at 2,400W continuous, with an X-Boost feature that pushes higher (up to about 3,400W) by lowering voltage and raising amperage — lights may dim slightly, but heavy tools keep running. The Jackery 2000 V2 sits at 2,200W with no boost mode. The Anker SOLIX S2000 is rated at only 1,500W — but the video's point is that a 1,500W inverter is enough for a typical refrigerator, which is the actual job these units do during an outage.
The perspective trick that matters: a standard wall outlet is rated 15A, i.e. 1,800W, so anything above that is already beyond "household normal." If your essential loads — fridge, freezer, Wi-Fi, lights — stay under 1,500W combined, paying extra for a 2,400W inverter buys headroom you may never use. That is the key value question this comparison keeps circling back to.
Battery Capacity: Almost Identical, With a Twist
All three units pack essentially the same energy storage: the Delta 3 Max holds 2,048Wh, the Jackery 2000 V2 holds 2,042Wh, and the Anker SOLIX S2000 holds 2,010Wh — while being physically about half the size of the Delta 3 Max. All three use LiFePO4 chemistry, with the S2000's compactness coming from pairing a smaller inverter with the same battery capacity. The S2000 is rated for about 10,000 cycles (at 60% usable capacity), versus roughly 4,000 cycles for the other two (at 80% usable capacity) — the video notes the marketing difference and that the real lifetime usable capacity is comparable.
One caveat the video flags: none of the three accepts expansion batteries, so you cannot add capacity later. That is a real limitation for people who want to grow a system over time — and it is a point in favor of systems (like our home storage batteries) that are designed to be stacked or paralleled from day one.

|---|---|---|---|
| Battery capacity | 2,048Wh | 2,042Wh | 2,010Wh |
| Inverter output | 2,400W (X-Boost ~3,400W) | 2,200W | 1,500W |

Efficiency and Idle Draw: Where the S2000 Wins
The most surprising result of the video is that the smallest unit ran longest. The S2000's inverter measured 96% efficiency — the highest the host has ever recorded on any solar generator — against 92% for the Delta 3 Max and 90% for the Jackery. Its idle power draw of 4W is dramatically lower than the 17W (Delta) and 21W (Jackery) of the bigger units. Over a 24-hour outage, that difference alone is significant: 4W idle wastes ~96Wh a day, while 21W wastes ~500Wh — nearly a quarter of the battery.
The runtime test makes the point concrete: the S2000 ran a refrigerator for 19 hours and 20 minutes, the Jackery 2000 V2 for 17h 25m, and the Delta 3 Max for 16h 55m. Despite having the smallest battery, the S2000 outlasted both rivals because less energy was lost converting DC to AC. For anyone who primarily runs essentials, this is the headline stat of the whole comparison.
Charging: Wall, Solar and Car
Because none of these units expands, fast recharging matters. On wall power, the Delta 3 Max and Jackery both charge at up to 1,800W (15A); the S2000 defaults to about 1,100-1,200W but has a boost mode up to 1,600W that must be toggled in the app — it does not do that out of the box. All three can technically charge from a car's cigarette-lighter port with the right DC adapter, though the video notes most owners rely on wall and solar.
On solar, all three share a 60V MPPT charge controller, and both the Delta 3 Max and S2000 use the common XT60i connector (the Jackery's proprietary DC8020 is not recommended). The Delta 3 Max tops out at 500W solar input versus 400W for the other two — a 20% difference. Since the US averages about five solar peak hours a day, 400W input produces roughly 2,000Wh daily, and 500W input up to 2,500Wh — enough to fully recharge any of these on a good sunny day, and to run daytime loads while topping up if your nightly draw is moderate.
Price and Bang for the Buck
Pricing changes constantly with sales, but at filming time the numbers were: Delta 3 Max $800, Jackery 2000 V2 $900, S2000 $600. The video's "whole watt" metric factors inverter, battery and solar input together: the S2000 lands at 73 cents per whole watt, the Delta 3 Max at 77 cents, and the Jackery at $1.03 — roughly 25% above the EcoFlow. By this measure the S2000 is the clear best value of the three.
Price-per-watt thinking applies beyond portable units. When you scale to a permanent battery, the same comparison — capacity, inverter needs, solar input and cost per usable watt-hour — is how you should evaluate home storage and commercial battery options too. The numbers change, the logic does not.
The "X Factors": Light, Compactness, X-Boost
Beyond the specs, each unit has a differentiator. The Jackery 2000 V2 is the only one with a built-in light — handy for outages and camping. The S2000's superpower is compactness: with only two AC outlets and the wall charger on the back, everything else is on the front, so you can tuck it into a corner without cords everywhere — a big deal for camping and off-grid cabins. The Delta 3 Max's X-Boost lets it push heavy tools up to about 3,400W, which matters if you occasionally run power-hungry equipment.
Two software-adjacent features round out the comparison. First, output tracking in the app: the Delta 3 Max and S2000 record how much energy came in from solar or wall and how much went out — the Jackery app is simpler and lacks this. Second, output memory (dark start): if the unit dies at 4 a.m. during an outage, it automatically turns its outlets back on once solar recharges it past about 10%, so your fridge and Wi-Fi come back without you doing anything. All three carry about a 5-year warranty.
Which One Wins, and for Whom
The host's verdict, with one asterisk: if you are running bare essentials — fridge, freezer, Wi-Fi modem — the Anker SOLIX S2000 is the pick. It is more affordable ($600), you do not need the bigger inverter, you get the same battery capacity, only slightly less solar input, and the 96% efficient inverter with 4W idle makes it outlast both competitors on the same charge. The Delta 3 Max is the choice if you need X-Boost headroom for heavy loads; the Jackery wins only if you specifically want the built-in light or prefer its app.
The asterisk: none of these units can run a whole house, and if your needs exceed 2kWh a day you should be looking at a scalable system — a stackable or high-capacity home storage battery, not a portable station. The same "match the unit to the load, then check the price per watt" framework applies at every scale, and it is the framework we use every day when engineering packs for customers.
