Jackery HomePower 3000: Specs and Runtime Math

The short version. 3,072 Wh of LiFePO4, 3,600 W continuous, 59.52 lb, no expansion batteries, $2,499 list. That capacity runs a fridge and a fan for about four days with no recharge. It is the right size if you cook on electricity or want home backup as a second job; it is roughly double what a weekend camper with a fridge and a fan needs, and the honest recommendation for that reader is to spend less.

Specifications, as published

Every figure below is from Jackery's own product page, accessed 13 August 2026. Two things are missing from this table on purpose, and both are covered further down: solar recharge time, because Jackery's own pages contradict each other, and maximum AC input in watts, because Jackery publishes only an amperage and we are not going to multiply it out and present the result as a specification.

What 3,072 Wh is actually worth

Not 3,072 Wh. The rated figure is gross capacity measured at the cells, and two things take a slice before it reaches your fridge.

1. Usable depth of discharge: we plan on 90 percent, so 2,765 Wh. Battery-management cutoffs reserve headroom at both ends of the pack and the inverter draws a little simply being switched on. This 90 percent is our planning constant across the site, not a Jackery figure - Jackery does not publish a usable-capacity number, and we are not going to attribute one to them.
2. Inverter conversion: a further 10 to 15 percent on AC loads only. Anything drawing from the household sockets pays it. Anything on the 12 V socket or USB does not, which is the single easiest way to make this unit last longer.

Cold does more damage again, and we are not applying a number to it, because the honest answer depends on the pack and the night. What Jackery does publish is the boundary: the unit will not charge below 32 F at all, and between 5 F and 14 F its output is capped at 2,000 W rather than 3,600 W. That second figure is worth knowing before you plan winter cooking on it.

What the capacity runs, in days

The load figures below are the same appliance presets our calculator uses - a 60 L compressor fridge at 50 W on a 40 percent duty cycle is 480 Wh a day, a 25 W roof fan for eight hours is 200 Wh, and so on. AC loads in the last two rows have the inverter penalty applied at 15 percent, which is the conservative end.

Worth reading the last two rows twice. Adding a kettle costs you a full day; switching to induction costs you three. Cooking on electricity is not a small extra load, it is the dominant term in the budget, and it is the only reason most people ever need this much capacity.

These are our numbers for our assumed appliances, not yours. Check this capacity against your own load - the calculator uses the same constants and lets you set the fridge size, the fan hours, and the trip length.

Recharge: what is published, and what is not

From AC, 2.2 hours to full. Jackery publishes this directly. Hybrid AC-plus-solar together is published as 1.7 hours.

From solar, we are not giving you a number. Jackery's own materials disagree with themselves: one Jackery page says 3.5 hours, another Jackery page says 5.5 hours using two SolarSaga 500 X panels, and Popular Mechanics reports 11 hours at 400 W of panel. We cannot reconcile those, and inventing an average of three contradictory figures would be worse than saying so.

What we can do is give you the arithmetic bound, which is not in dispute because it follows from the published input ceiling:

• The DC input is capped at 1,000 W. So 3,072 Wh cannot enter the pack in less than about 3.1 hours, regardless of how much panel you connect. That is a floor, not a prediction.
• Panels do not deliver their rated output. Using the 70 percent real-world yield factor our calculator applies, you would need roughly 1,430 W of rated panel to actually hit that 1,000 W ceiling - and even then only around solar noon, in clear conditions, at a good angle.
• With about 4.5 effective sun hours in a good summer day, a full solar recharge from empty is realistically a whole day of sun, not an afternoon.

Maximum AC input is not published in watts. Jackery states only "100-120 V, 60 Hz, 15 A Max." We are not multiplying that out, because the result would be a number Jackery has not stood behind.

Who should buy less than this

This section costs us money and it is the reason to trust the rest of the page. Run the numbers on your own load before buying this tier.

A typical vehicle-camping load - a fridge, a fan, lights, phones and a laptop - is 600 to 900 Wh a day. Over a three-night weekend with a modest solar panel, that needs somewhere around 1,200 to 2,000 Wh of gross capacity. A 1,000 to 1,500 Wh station covers it, weighs half as much, and costs well under half as much. Buying 3,072 Wh for that job means carrying 27 kg of battery you will never discharge.

The capacity earns its price in four situations, and not really otherwise:

• You cook on electricity. Induction is the load that justifies this tier on its own.
• You run a medical or always-on device alongside a fridge, and you want margin rather than a calculation that only just works.
• You work from the vehicle with equipment heavier than a laptop.
• You want home backup as a second job, in which case the 20 ms UPS switchover and the TT-30 outlet both matter - though note Jackery explicitly says this is not 0 ms and does not recommend it for sensitive equipment.

If none of those describe you, other stations in this capacity band includes smaller units that will do your job.

Alternatives at the same capacity

On published specifications only - we have not tested any of these either. The clearest comparison is the EcoFlow DELTA Pro: more capacity at 3,600 Wh, the same 3,600 W continuous output, expandable to 25 kWh, but about 99 lb against this unit's 59.52 lb. If you expect to add batteries, that is the decisive difference, because the HomePower 3000 cannot be expanded at all.

For the brand-level picture across every capacity tier, including where Bluetti fits, how Jackery compares to EcoFlow and Bluetti covers the differences in chemistry, recharge behaviour, app quality, and warranty support.

What we cannot tell you without testing one

Named rather than quietly omitted, because these are the things that decide whether a power station is good, and a specification sheet answers none of them.

• Real delivered capacity against the rated 3,072 Wh. Our 90 percent figure is a planning constant applied to every station on this site. It is not a measurement of this one.
• Inverter waveform quality under load, which decides whether sensitive equipment is happy on it.
• Fan noise, and at what load the fans come on. This is the most common complaint about high-output stations and it needs a sound meter and a quiet room.
• Cold-weather behaviour beyond the temperature limits Jackery publishes.
• Build quality, port durability, and app reliability over a season of real use.
• Long-term degradation against the 4,000-cycle claim, which by definition takes years to verify.

What would unblock these: owning the unit, a clamp meter and a resistive load bank for the capacity test, a sound meter, and a winter. Until then, on independent coverage, the only named reputable publication we found with hands-on time is Popular Mechanics, and their piece is explicitly first impressions rather than an instrumented test. Several affiliate review sites publish confident figures for this unit that contradict Jackery's own specification - we found ones claiming 400 W solar input, 3,000 cycles, and expansion-battery support, all of which are wrong.
